Aerochrome was pretty darn cool.
Do you plan on using it with a yellow filter or doing something more funky?

I'll probably shoot it with a yellow filter using my Bronica ETRSi so I can get 15 shots.

I recently developed a pressing need (that's the FW's custom term for "I couldn't resist G. A. S.", right?) to get a Zenza Bronica SQ-A. I've had my eye on a medium format SLR for some time and I particularly liked the Zenza Bronica ETRSi, however, I came across this Zenza Bronica SQ-A which is in superb condition (it looks like it's hardly been used). It came with a film back for 6x6 and one for 6x4,5, the Zenzanon 80mm f/2.8 and the 50mm f/3.5 as well as a lens hood that fits both, and the waist level viewfinder. Having both backs makes this a very versatile camera. The light seals of the film backs look superb (I've read that a lot of SQ-As have trouble with light leaks there). I'm looking forward to trying this beauty tomorrow.

Nice one cs1, I wonder if the lenses and backs are compatible with the ETRSi.  Everything looks very similar.

Unfortunately they are not compatable with the Etrsi.

As Mike already pointed out, they aren't compatible. I'm going to look for the 150mm or the 200mm, they look like they're really nice. As soon as I've recovered from this acquisition... ;)

Picked this up for $0. Originally, it would have been around $17 on Amazon, however, since I ordered it for "same-day delivery" and they delivered it too late (this morning), they reimbursed me for the purchase. I also picked up (on the same order) 4 books, Vonnegut, Kerouac, Hemingway.

congrats on the SQ-A. It was my first medium format SLR and I loved the thing. It's pretty light and compact, the lens is fantastic and quite fast. I've owned 2 so far and both were fantastic cameras. Guard that WLF and that advance crank with your life. Those are the most desirable parts and always in constant demand and command high dollar.

Enjoy

Thanks, SLVR. I just replaced the light seal foam that seals the mirror when it's in the upper position which was quite a fiddly thing to do. But I'm glad that it's finished now. The light seals on the film backs are like new. I shot one film with the 6x6 and one with the 6x4.5 back and both are without any leaks (though it was really sunny). Why are the cranks and the WLF so high in demand? I thought that the SQ series (except for the SQ-Am) came with them by default? I just managed to get a Prism AE viewfinder for 50 € which is quite a good price if I'm not mistaken (it hasn't arrived yet). It looks quite used on the outside but the prism etc. look ok. The seller is willing to take it back if it doesn't work so no worries there.

Miguel, nice set of filters. Looking forward to shots where you use them. :) I also like the Burberry (?) strap, very classy. :)

a lot of pros back in the day ditched their WLFs for metered prisms. The WLFs got lost or never stayed with the camera when it was sold on. Same with the cranks, people will put the grip on the SQ-A which has a frame advance lever built in. You need to remove the crank in order to use it and the crank again gets lost.

Nowadays people want to shoot with a WLF instead of a prism so WLFs usually demand a high price for culty cameras like the SQ.

I find that etrs WLFs though are cheap. Don't know quite why.

Then I'm glad that the WLF and the crank are still there. It's such an enjoyable experience to shoot with the SQ-A. Though the lenses are really heavy (the build quality is brilliant) the camera feels well balanced and is just a joy to use. However, it's not a discrete camera, that's for sure. It loudly yells "Hey! I just released the shutter!" at you every time you push the shutter release. There's no doubt about when it successfully fired. :) It's a very "force feedback" sort of experience.

If you get a prism a lot of people think that it's a video camera. I didn't seem to get as many people bothering me with the prism. Though no one really bothered me at all with the SQ-A in general.

I got the prism viewfinder today and it's in a good condition. I mainly got it for the 6x4.5 back because I think that it's a real pain to take portrait oriented photos with the WLF. But apart from that I absolutely prefer the WLF.

You can't rotate the back on the SQ-A. But I can live with that. I've read that some people complain about some features of the SQ-A regarding the back. For example that you can't release the shutter without film in the back (only on multi exposure mode) or that the back will only come off if the dark slider is inserted. However, I think those are actually useful features and I can't see the negative sides of them. Not having a rotatable back is the only minute downside.

Picked up 5 rolls of Neopan 100 and a 10-stop filter from Tiffen. Hopefully, there's good weather this weekend so I can try it out. Also, a question regarding long-exposures... Wondering if stacking a contrast filter on top of it would be worth it to bring out any sort of clouds/sky detail, even if blurred.

Stacking filters would make me worry about reflections between the two filters. If you do it, I'd probably screw on the color filter first and then the ND filter. However, I've never tried it myself so I don't know what your mileage will be. Theoretically the color filter should work normally because the ND filter shouldn't change the colorisation.

I've done the stacking thing before and it's not as bad as it seems. But even with supposedly neutral filters, the color balance does go out the door. But in B&W it doesn't really matter. All you'll get is slightly softer results, though I can't be sure if my experiments' fuzziness was caused by my tripod moving in the breeze or the filters.

re: color shift. There are some 10 stop filters that cause more color shift than others. Just something to note. I can't say for certain if this one has shift or not.

Ignore the camera for a moment, it's the lens you need to concentrate on here.  The venerable Meyer Optik Orestor 100/2.8, made around 1970 in Gorlitz on the border with Poland, just down the road from Dresden.  If you don't know the lenses, well, tough, 'cos they're quite difficult to find in M42 in good condition.  The one in the pic is the first one I had, back in 2005, and which I stupidly sold.  The replacement was fine for a long time though first the auto pin went, and then finally the aperture blades themselves - for quite a while I only used it wide open anyway.

But I've just found another that was going cheap (relatively) with perfect functionality but trashed coatings.  Fortunately it is the same model so when It arrives I will have some satisfying fun unscrewing the lens units and transferring them, swapping them over.  A ten minute job on account of the ultra logical design of Meyer's lenses. 

Yes, they are better than many of the 35mm Zeiss lenses of the period.  Here's an example of why I like it:

And another, both on Acros and a Pentax body:

I know Zeiss weren'gt always considered the best in the business. For a long time Hasselblad used Kodak lenses on their cameras because Zeiss lenses were "not good enough"... how things have changed  ::)

Early on yes, but in the screw-mount era most aficionados of German cameras I know pull for Zeiss, I guess on the basis of a couple of excellent lens designs.  It's just that they weren't all so very good.  Meyer was considered a minor player, but as ever, #2 tends to work harder.  And optics apart, if you ever dismantle a Meyer and a Zeiss 50mm there's a huge difference in how quickly you can put them back together again.

I've had bad Leica GAS lately but this should help.  I sold off all my Pentax K1000 kit and a few other items for this.  Everything functions properly on the Leica IIIf, it just has a few cosmetic issues with the leather.  Based on the serial number this one was assembled in Canada but it still says made in Germany.  I did buy it from a seller in Canada.  The Chico flash works but I have not tested it with film yet, just need to figure out the proper synchronization number for Press 25 bulbs.  I have had the Weston Master light meter for a while now, it's model 715 made between 1939 and 1940.  Surprisingly the light meter is still accurate.

You can use B mode for this.
Press the button and release as soon as the bulb has fired. That should do it :)

When I was a kid, there was something magical about flashbulbs. I wish I had saved some, and a flashgun, when I had the opportunity. There's an older thread on RFF that might be helpful; see https://www.rangefinderforum.com/forums/showthread.php?t=54159

The 1955 edition of the Leica Manual lists the following synch settings :

#5 / 25 / 0 bulbs:

Black-dial: 1/30: 16; 1/40: 11; 1/60: 8; 1/100: 8; 1/200: 4; 1/500: 3.5; 1/1000: 2 .

Red-dial: 1/25: 14; 1/50: 11; 1/75: 6; 1/100:4; 1/200: 2; 1/500:1; 1/1k: 0.

Thanks Earl, I’ll have to try a few of those numbers, it sounds like M bulbs are not ideal for focal plane shutters so a slower speed like 1/50: 11 may work well.  I have several boxes of Press 25 bulbs to play with.  The sound and smell of the bulbs do bring back childhood memories for me.

Turns out my last roll of TMAX 100 was the last roll of 35mm B+W in the freezer. Freestyle's warehouse is about a 20 minute drive, so I decided that it's time for my annual-ish replenishment run. I haven't used Foma or Bergger films before and took the opportunity for something other than Kodak or Ilford stock, and thought I'd give TMAX 3200 a try as well.

There are some things you just can't resist...



I mean, look at it. I have exactly zero need for it, but I couldn't walk away. I haven't decided whether to leave the aesthetics as-is or do a full resto. Mechanicals are working well after a quick clean-and-lube, and the glass is nice and clean. Test roll will go in today.

Yeah, that was part of the appeal. It's really a fascinating mechanism. Fairly simple, seemingly quite robust, and reasonably smooth (once I got it cleaned and lubed, anyway). For those unfamiliar, it's a rotating blade shutter. There are two overlapping discs with wide pie-shaped cutouts. Setting the shutter speed varies the position of one, opening or closing the gap in the disc. The actual rotation speed in constant regardless of the setting. Speeds range from 1/1000 to 1/20, plus B and T; no slow speeds is the trade-off. The hump on the top of the camera is necessary to accommodate the shutter discs.

It sounds like a movie camera shutter.  Most of my Bolex cameras have a similar shutter that allows you to adjust the size of the opening.

Could be - I have no experience with movie cameras, but I can see how the design would be useful in that application, rotating continuously rather than once.

The Mercury II Model CX is one of my all-time favorite cameras.  I picked up one about six years ago for a few bucks on ebay and shot many rolls of film with it.  I liked the camera because of its unique features and because, even with the half-frame format, the images were excellent and capable of considerable enlargement due to the good resolution of the Tricor lens.  In the company's post-war advertising campaign, much was made of the reliability and accuracy of the Mercury's shutter which an independent testing lab had shown to be superior to Leica and Contax.  Soon after I got my Mercury I did some recon on the web for information about the history of rotary shutters and put what I found into a post on the subject on my blog.

and a man who thinks his equipment is going to see for him is not going to get much of anything.

The thing i wonder about is the why there weren't more cameras that use this type of shutter?
With a bit more engineering they could have fitted slow speeds. And since it freely rotates, it should be a very smooth operation.

I think the main issues with rotary shutters are size and inertia.  That big hump on the Mercury was needed to accommodate a pie-shaped opening in the shutter disk that would cover the 35mm half-frame format.  A shutter of this type using the Mercury strategy for 35mm full-frame would have been gigantic.  Regarding inertia, it takes some clever engineering to get the rotary shutter moving and then to stop it after the proper interval.  Maitani's solution regarding inertia was to use exotic materials and ultra-miniaturization of components.  Movie camera shutters generally operated at one or two rather slow speeds and were thus small and simple.

The big advantage of movie camera shutters is that they don't need a break that can support thousands of actuations. Also their small size makes them put less stress on the parts.

If I were to design one, I would probably put a half geared spindle on one of the discs or a friction mechanism that would activate an air brake (paddle type) at the end of the run.

The Bolex shutter must have some kind of break on it because it always stops in a closed position.  If that didn’t happen you would have a very over exposed frame between each shot. 

I have always wanted a Mercury II, now O2Pilot has me thinking about it again.  I just sold a bunch of stuff so there’s plenty of cash burning a hole in my PayPal account.

I think this is a common feature on all movie cameras. My Bolex has it. My Brownie has it. My Canon has it...
