Seagull 4A-105 Review

[If you like this blog, please click the ad at the end of this post to help it grow. Thank you.]

A twin-lens reflex (TLR) camera offers you an entry price point into medium-format photography. Instead of the usual SLR design of cameras such as Hasselblad and Mamiya, a TLR has two lenses. The top one provides an image on a ground-glass viewing screen and the bottom is used to record the photograph directly onto film.

The 4A-105 is the latest in a succession of models from the Chinese twin-lens reflex manufacturer Shanghai Seagull. Each model that has appeared has had slight modifications to improve the handling and this one includes the following:

Seagull TLR review

The Seagull costs 189 including VAT and is available from importer Kauser in Hertfordshire. It looks very much like a Yashica 124G or old Rolleiflex and is designed to be used as a waist-level camera. A hood flips up on the top and allows you too look down onto a shielded screen to focus and compose your photograph. The hood is easy to return to its flat storage position. You just squeeze the sides and give a gentle push and it all collapses into place. Raising is just as easy – gripping the sides and lifting so it springs into place.

Seagull TLR review When you look down into the hood you see a reversed image. This is one of the disadvantages of this type of camera and does, if it’s your first time using one, take time to grasp. If the subject moves to your left it will appear to move to the right in the viewfinder and your instincts won’t follow.

To use the camera you cradle it in the left hand and use your right to wind the film on and press the shutter release. The plunger is threaded so a cable-release can be attached.

 

Seagull TLR review The viewing screen has a ground glass surface to help make the image easier to focus. It goes slightly darker into the corners, but overall the image is bright thanks to the f/2.8 viewing lens. In the centre is a horizontal split line surrounded by a microprism style circle. These are used to provide accurate focusing. The split image is a familiar item on single-lens reflex cameras and splits the subject’s vertical lines in two when the subject is out of focus. As you move to the correct focusing distance the lines gradually become closer until they meet and correct focus is obtained. The microprism shimmers when the subject is out of focus and appears clear when it’s in focus. You can use each or a combination to help you gain perfect focus or, at least, that’s what you hope! (see comments later)

 

If you rely on peering down into the finder you won’t be able to focus accurately and to assist the Seagull has a pop up magnifier that you reach by pressing in a plate on the face of the hood. The magnifier is used with your eye pressed up to it and still allows you to view the whole image area, but concentrate on the inner focusing aids.
A large knurled wheel on the left of the camera is used to focus and the lens mount moves backwards or forwards to adjust the lens’ distance from the film.

 

Seagull TLR review

I found the focusing hard to determine. Despite having both options, neither seemed to be very accurate and it took too long to be sure I was happy.

Also look at the bright white vertical line to the right of the magnifier (pic above). This is the hinge of the hood and it lets light in. Although this will do no harm to the film it did cause stray light to hit the focusing screen in bright weather and made it difficult to focus, especially when the sun was in front of me.

Seagull TLR review If you push the plate on the top of the hood fully in it locks down at both sides and allows you to view directly through the hood when raised. This is called a sports finder and is designed for fast action pics where focusing is at a predetermined distance, so you can have everything set up and use the camera like a direct vision model. Crude but quick.

 

The latches that lock it down are not secure enough and it occasionally popped back up when I caught the hood, by accident. The advantage here though is it does always flip back up when you want it to. On some cameras I’ve used you really have to tug at the hood to make it spring out of the way.

Seagull TLR review When loading a film you release the back using a dial on the base of the camera. This rotates to release a spring mounted catch and the back hinges open. Two plungers spring out to allow the film spool and take up spool to be positioned and locked in place. When the film’s loaded you shut the back and rotate the dial to the C position which pulls the catch inwards to secure the back. The gap at the bottom seems wider than the one at the top and it looks as though it’s ill-fitting. No light got in so this is just a cosmetic thing. I’d prefer to see it flush with less movement, I was initially conscious that the lock might release and the back would spring open while I was using the camera, but it proved solid enough.

Four raised metal feet ensure the camera balances firmly when placed on a table, but these got in the way of the tripod platform I used and didn’t allow an even fixture.

When a film has been loaded you use a large advance lever to wind on. The camera locks at frame 1(indicated in a small circular window above the wind on lever) Safety features ensure the lever will not advance until the shutter is fired and picture taken. The shutter will not fire until the film is advanced. There is no shutter lock so I would suggest you only wind on when ready to take a photograph to avoid accidental shots. The 4A-107, with its four element lens, does have a shutter lock.
The lever is quick to advance film and has a good action.
Seagull TLR review

There is no exposure meter built in to this camera instead you need a handheld meter or a good knowledge of exposure settings.

Seagull TLR review When you know what the exposure is, you set it on the dials at either side of the lens. The left hand side has shutter speeds, the right hand side has apertures. These slide to adjust. The shutter speed is click stopped and the aperture is smooth, allowing infinite adjustment between settings. Both are positioned so you can adjust with the thumb of each hand as you cradle the camera. I’ve already picked up on several crude points of this camera and the worst is the shutter speed marker that doesn’t align correctly with the settings. It’s about half way in between so if you forget which way this appears you have to slide it to the extreme to see which setting it actually refers to. The aperture slider is a little coarse and appears to grate as it’s moved.

On the picture above you can see a small lever with a red dot just below and to the right of the word REFLEX. This is the mechanical self-timer that allows a variable delay of between 8 and 14 seconds depending on where you move it to. It’s all guess work so you’ll need to get a feel for how far you need to pull it. Practice without a film in the camera.

We used this for some interior shots to prevent camera vibration when it was mounted on a tripod. Three shots later and it broke! The film advance still worked but the shutter release didn’t open the shutter or activate the timer, resulting in the third roll of film being blank and the camera inoperable.

Below the self timer is a standard flash sync terminal which is used to connect any electronic flash with a coaxial cable. There’s also a more convenient hot shoe on the side although this was slightly loose on our model so I wouldn’t trust it with a larger gun. The beauty with a camera like this, with its leaf shutter, is flash can be used at any speed – shame the top speed is only 1/300sec, but it’s still as good as the best SLR cameras and proves perfect for fill in flash in most conditions.

Seagull TLR review The focusing wheel provides smooth adjustment and is easy to control. On the side is a depth-of-field scale indicating distances in meters with all the apertures. The red mark shows where you’ve focused and the alternate black and white marks show the depth-of-field at the various apertures. This is a well designed scale and very easy to use.

Test pictures

Seagull TLR review A straightforward shot of flowers. The subject was about 1.3metres away and overcast lighting ensured there was no complex metering involved.

There’s good detail in the plants and the background is subtly out of focus thanks to the selected f/3.5 wide aperture. This was taken on Fujichrome RDP100.

 

Seagull TLR review The lens shows no signs of vignetting into the edges which is something you may find on older TLRs, but the photos are not razor sharp. When magnifying the railings in the centre of the frame it was noticeable that details was starting to fall. Overall it the trannie would enlarge to about 12in without problem, but so would an image shot on a good 35mm SLR,

 

Seagull TLR review I deliberately ensure the bottom of the upper window was included in the frame to see how the lens responded to flare. There’s a fair degree of ghosting. This shot also shows the lens doesn’t suffer from distortion.

 

Seagull TLR review
To check my constant annoyance of the focusing accuracy I deliberately set the lens to f/3.5 and chose a subject with a variable distance background. I used the magnifier to focus on the wooden sculptures. The camera was mounted on a sturdy tripod and the delayed action used to prevent any movement. I didn’t focus accurately. And that’s a big problem. There’s no point in having all the benefits of a larger format camera if you end up with out of focus pictures. The camera definitely needs a better focusing screen!

 

Verdict
Throughout the test I have been fairly harsh on this camera, particularly in construction. For background info I have owned or usSeagull TLR reviewed many medium-format cameras over the years. I admit I prefer the single-lens reflex type, but readies the TLR has a very useful place. One of the main benefits is the lack of a mirror clunking around causing vibration and noise. The shutter is almost silent on a TLR and there’s no vibration. The Seagull delivers in both these areas a great camera for candid photography and one that can be used in church for weddings without annoying the vicar. The other main benefit of a TLR is cost. Currently the Seagull is the only one you can buy new and I suspect that’s why it has a price of 189. When you could by the Yashicamat 124G, a better built camera with a built-in exposure meter, it sold for about 149. SLRs haven’t risen in price since then, so there’s no reason why this would have happened to TLRs either. If the Yashica was still available it would probably have cost no more than 160, in relative terms this makes the Seagull worth about 130 maximum. Overpriced but no alternative? Well yes, If you don’t mind buying a second-hand camera you can pick up a Yashicamat 124G for about 129 and in my view it’s a far better camera. You can also find Mamiya TLR cameras with interchangeable lenses for a similar price to the new Seagull and they have better build and much better close focus capability. You may even prefer an SLR and it’s possible to buy old Mamiya 645s or Bronica ETRs for not much more than the Seagull.

Having said all this, if you prefer the comfort of a new camera and don’t mind paying slightly over the odds, the Seagull will not disappoint in optical performance, providing you can get on with the focusing and can put up with the crude aspects of the build, oh and avoid that self timer!

Update! Comment from supplier

Volume determines price. The factories does not sell the numbers they used to. Competition is another factor. In the days of the Yashicamat there were several TLRs in the marketplace. Today, there is the Rollei and nothing else.

The Seagull is not the tin box it used to be and Minolta’s input has improved the quality of components and build. It still has some way to go to match that of the German & Japanese but gradually it is getting there. Ali Kamruddin, Kauser International

Also regarding price: Global Cameras sell the camera for 160 which makes it a better buy.

Rollei Rolleikin 35 mm. Back (with pictures)

Rolleikin 3.5 and 2.8 A. Installing the Counter-knob B. Assembling the Rolleikin
C. Loading D. Film Transport E. Rewinding
F. Note Bottom of page

Parts of the Rolleikin back

Rolleikin 3.5 and 2.8Fits Rolleiflex 6 x 6 above numbers 1,100,000 and Rolleicord above numbers 1,137,000. (The combination back for two picture sizes was originally not provided with the first camera series, but could be ordered additionally). Earlier Rollei-models 6 x 6 use Rolleikin I (with special back).

Designed for: Taking up to 36 exposures 1 x 11/2 in. on 35 mm. film. Ideal for series of pictures and color photography on miniature film.

The attachment consists of:

  1. Case
  2. Film Guide Frame
  3. Take-up Spool
  4. Exposure Counter Knob (not required with Rolleikin 2.8)
  5. Extension Spindle for Rewind Knob (two types, for previous and new Rollei models)
  6. Inner Spool Knob
  7. Focusing Screen Mask
  8. Direct Viewfinder Mask
  9. Lens Hood Mask

A. Installing the Counter Knob (not required with Rolleikin 2.8)

(The exposure-counter-knob accepts 35 mm. film and 120 film)

  1. Remove the top film-knob by unscrewing the three countersunk screws.
  2. Fasten counter-knob tightly by means of the three screws supplied.
  3. Remove protective lining from gummed insert and paste it on the counter knob.

Assembly

B. Assembling the Rolleikin

  1. Adjust film pressure plate by a sliding movement, pressing down at the same time, thereby bringing the inscription 24 x 36 mm. (not required with Rolleikin 2.8) into view.
  2. Pull counter-knob, fit take-up spool on the right and insert completely.
  3. Rewind-parts: Screw extension-spindle on rewind-knob by rotating the latter. Snap inner spool-knob over opposite spool bearing pin, (slipping the metal tongue between the rollers of the film-feed when using a Rolleiflex).
  4. Inserting the film-guide frame: Press spring actuated clamp-bar at an acute angle (as shown) against the bottom of the film gate and insert completely. To remove: Push frame downward (against the clamp-bar) and lift out.
  5. Place ground-glass mask (in fitted position) on ground glass screen and slide under front clip, snap down and secure by depressing clip of retaining device at rear of focusing hood. Be sure the mask is properly centered and not jammed inside the ground glass frame.
  6. Insert the framefinder mask underneath the button above the framefinder in such a way that the edge is pushed in first, then press the two lateral fixing buttons into position. (see illustration below)

Loading

C. Loading

  1. Open camera back, pull rewind-knob, fit in film cartridge on the left and then insert fully.
  2. Introduce the film-lead (which – in the Rolleiflex – first passes through the film-feed rollers) into the double slit of the take-up spool, letting it touch on the right. Tighten up by giving spool a short turn.
  3. Make sure the mouth of the cartridge points straight ahead in line with the tightened film lead, then close back.
  4. Press-and-release counter-knob until the red dots of the Rolleikin counter face each other. (Disregard counter for 120 film completely)
  5. To set counter for the first exposure: Advance counter dial to No. 1 by actuating film transport three times.

Film Transport

D. Film Transport

  1. Press-and-release counter-knob before actuating film transport. The exposure counter advances automatically to the next number.
  2. Advance film as usual to the stop.

E. Rewinding

  1. After the last exposure has been made, rewind film by keeping counter-knob pressed down,
  2. simultaneously rotating rewind-knob clockwise.

F. Note

  1. The rewind also permits the removal of only partially exposed films. In order to prevent the film lead from slipping into the cartridge when rewinding, be sure to thread the film backwards i.e. against the winding direction into the double-slit of the take-up spool when loading. When rewinding a partially exposed cartridge, advance film two frames beyond the last exposure (skipping one frame for safety).
  2. Always adjust film pressure plate properly (see B1). (A sure sign of incorrect adjustment when using the Rolleikin: camera back will not close all the way)
  3. When installing the Rolleikin in the camera the empty roll film spool should be laid safely away in the Rolleikin case for later use since it must be used again when inserting the next roll of film.
  4. Shutter cocking as usual: With Rolleiflex, normal swing of the crank.
  5. Double exposure device is in operation in the Rolleiflex and cannot be disengaged when using Rolleikin. With Rolleicord it must be disengaged in order to unlock shutter.

Yashica Mat 124 Review

When I took this step forward, back to film, I wanted something more than what I could get from 35mm.

So I started looking at medium format cameras.
The Yashica Mat-124 was one of the first medium format cameras that I got, a birthday present from my wife.

Yashica Mat-124 (7)
Review:
The Yashica Mat-124 is a twin lens reflex (TLR) waist level finder medium format camera.
This is a Rolleiflex clone, maybe the optics are not in the same league, but I’m very pleased with the results that the four elements in three groups, 80mm 1:3.5, Yashinon lens delivers.
In the lens-board it has the viewing, top, and taking, bottom, lenses.
The shutter speed and aperture controls, round dials on each side of the lenses.
The flash socket, top right and flash synchronizer lever, the yellow dot behind the aperture control dial.
The red dot, at five o’clock of the taking lens is the delayed shutter release lever.
On the bottom left there is the shutter release and lock lever, in lock position.
Above the lens-board, to the right of the embossed brand and model, that round “eye” is the window of the CdS light meter, powered by a defunct PX625 mercury battery.
I solved the problem, in this and other cameras with an adapter to zinc-air batteries, used in hearing aid devices.
Yashica Mat-124 (2)
That big round knob is the focus control, turning it makes the lens-board go back or forth allowing the user to control the focus on the ground glass.
On this kind of cameras the focus achieved in the ground glass is the same of the taking lens, at full aperture, due to the solidary movement of the lenses. One has to be careful with the parallax error, at close range, caused by the distance between the lenses.
The distance scale is engraved on the outer rim opposite the depth of field scale engraved on the chrome plate.
The two smaller knobs, top right and bottom left are the spool locking knobs.
On the bottom right is the battery compartment with its chrome lid.
Probably you have already noticed something missing on the top left. I removed the accessory shoe, for two reasons: one, I don’t plan to use a flash with this camera and two, the camera doesn’t fit the case with it on place.
Yashica Mat-124 (3)
The big film wind crank, that doubles its function cocking the shutter, dominates the scene on this side.
When its winded all the way clockwise it winds the film to the next exposure.
Winding it back, CCW, it sets the shutter.
I love that “taka-taka-taka…” sound.
The window over the crank shows the type of film being used 12ex (120) or 24ex (220).
The window on the top right shows the number of exposures taken.
The loading process of the rollfilm avoids the use of a red window by aligning the start marking of the film with an arrow on the film path, in the camera. From there all we have to do is wind the film to the next frame.
Yashica Mat-124
Here it is with its beautiful brown leather case, with a story of its own
Yashica Mat-124 (6)Yashica Mat-124 (4)
You can see it with the hood opened, ready for action, inside it there is a 3x loupe, that can be flipped up, for critical focusing.
Peeking through the sports finder
There is also this sports finder, for fast action photography. It’s a great asset, you know what I mean if you ever used a waist level finder camera before. In the finder one gets a left-right inverted image, that can be puzzling if you’re not used to it and are trying to follow a moving subject.
The light meter is quite accurate but gives a too wide reading.
For critical readings demands for proximity or ingenuity.
This is a very nice and usable camera, if you don’t mind to be stopped by people on the street that want to admire your camera, and also if you don’t bother to carry more than a kilogram worth of camera.
I think it pays…
