Related: About this forumGot new used tripod and lens, and have a request
I am getting ready for my Fall Foliage Trip - lots of planning, money-accumulating, planning, replanning...anyway, I decided to use my state tax return to buy a decent travel tripod and a wide-angle lens for my Mamiya 645. I ordered it Sunday, and it's here now.
The tripod is a MeFoto Backpacker. MeFoto sells these neat little Benro-made folding tripods that have black legs with colored accents so they look cool. This is a very good tripod. It is metal everywhere you'd want it to be metal. It has good-quality rubber on all the knobs and locks. Finish is anodized. Its head-mounting bolt has the standard 3/8"-16 thread and the quick-release plate is Arca-Swiss compatible, so you can easily get more plates for your other fifteen cameras and can also replace the head easily if need be. (It's a very nice head so you probably won't want to change it.) The leg locks are twist-lock not lever-lock; I didn't take a leg apart to see how hard it would be to clean sand out of it, but it shouldn't be that bad - the guy who invented this thing seems to have known what he was doing. There's a cute little retractable hook on it to hang a sandbag for extra stability. Its stated capacity is 4 kg. I haven't done extensive testing, but I did run it up all the way and stick a 6-pound Mamiya on it, and it was surprisingly shake-free. And it's purple! Or red, blue, aqua, black, silver or any of the other sixteen colors it comes in. They even give you this adorable shoulder bag to put it in. It has no spikes on the legs, which is fine by me because spikes on tripod legs are as useless as Republican campaign promises. If you don't like twist-lock legs or ballheads this tripod isn't for you; otherwise, you want one. There are two versions - aluminum legs for around $130, or carbon fiber legs for twice that. I'm not sure how overloaded you'd have to be to want the carbon fiber one, because the aluminum one doesn't weigh very much.
The lens is a "Mamiya 645 45mm f2.8C Compact Lens." Since not even MamiyaLeaf's own website admits this lens exists and there aren't any reviews of it online, this may be the Internet's introduction to the little beast. I will write a full review of it after I've had a chance to go out and put a few rolls of film on it, but these are first impressions:
When the lens is mounted on your camera, it sticks out a bit over two inches. The front element is close to being spherical; the front of the glass is REAL close to the front of the filter threads, so a UV/haze filter should be considered an absolute necessity here. (It requires 67mm filters).
Mamiya had two generations of M645 lenses: "C" and "N." As far as anyone can tell, "C" means Coated and "N" means New. The lens formula on the N lenses is supposedly improved and the coatings are slightly better, but Mamiya has always made exceptional glass; whether you get a C or an N lens, you will get good pictures.
There is no plastic in this lens. Everything that is not the rubber grip rings is either aluminum, brass or stainless steel. My specimen shows signs of being mounted frequently; since this is a pro lens, that's good - it means it was doing what it was purchased for.
The focusing range is 1.5 feet to infinity; the focusing action is silky smooth. Apertures are from 1/2.8 to 1/22; off the camera this ring also turns smoothly. (On the camera is a different story; the ring turns a gear that reports aperture to the automatic-exposure prism, and that always feels like you're cranking a lawn mower by hand.)
Until I get some images out of this lens I can't give a full endorsement, but I like what I see.
Now for the request: The new fad is to buy Mamiya 645 lenses and adapt them to DSLRs. Quit doing that shit. Our lenses are corrected for medium format film and won't perform properly on your camera. Our lenses don't work with your autofocus and auto aperture systems so using them on your camera is a grade-A pain in the ass. And you using medium-format lenses on non-medium-format bodies means there's now a shortage of them. It's not our fault Nikon and Canon have cheapened up their new glass to the point it's not worth buying. There are TONS of classic Nikon and Canon lenses on the market that'll work better for you than ours ever will.

(36,827 posts)But people have been adapting lenses for different cameras for a long time, so it's really nothing new. It doesn't seem to be worth adapting medium format lenses to 35mm. Doesn't Mamiya use leaf shutter lenses? Not even sure how you'd adapt that. At best it's just going to add more weight for no advantage. Not having autofocus and auto aperture isn't a big deal, though. I just bought a Bronica SQ-A which has neither and I don't think I'll miss it. My Nikon FM2 also has neither.
I've never considered UV filters necessary for any lens just to protect the front element. I know lots of people do. Personally I use a lenscap. If I'm taking a picture, the lenscap is off. If I'm not, the lenscap is on. It's the best protection I've found and all my front elements are in as good shape as when I bought them. To me it's not worth keeping an extra piece of glass between the subject and the media which is always going to introduce more aberrations regardless of how good the filter is.
I can't speak for Canon, but even Nikon's cheap lenses are quite good optically, although their construction and handling leave a lot to be desired. Their top end lenses are still extremely good. They also continue to sell some of their lenses that haven't changed in over 20 years. They are very expensive, though. Other high quality lenses which are far cheaper might be the attraction. I can kinda see this with Canon, but with Nikon you can still buy and use the old manual focus lenses, many of which are quite cheap and have excellent glass. They also tend to handle better than autofocus lenses.

(50,557 posts)Normally I would agree that a UV filter isn't necessary...but on this lens, I'm going to install one because I've never had one with the front element that close to the front of the lens barrel before.
Speaking of your SQ-A...have you seen http://www.cameramanuals.org/bronica/bronica_sq-a.pdf? (This guy buys old-camera manuals and scans them in, then posts them on the Internet.) On the left side of the Bronica's lens there's a depth of field preview lever; if that's stuck or broken, the auto aperture that all SQ-A lenses have won't work.
I have a 28-70 3.5-4.5 AF-D on my F4, and it's a very nice lens.

(36,827 posts)I could not find a manual for the ME finder I have for it, but I eventually figured it out. I've only shot one roll through it so far and I mailed it off to be developed and scanned. I have a 50mm and a 150mm lens for it, both are the S versions.
I'd love to have an F4 to be able to use non-AIS lenses. I'll probably get one someday. They are quite cheap these days.

(36,827 posts)I don't have an AE finder, and instead have the ME finder, which is simply a prism finder with an incorporated light meter. So I could be wrong, but I just don't think there's any way I can get auto aperture without changing the finder. Even if I did have any sort of auto exposure, I wouldn't want to use it on this camera. With the 6x6 format, you only get 10 shots per roll of 120, so I want to make sure every single exposure is exactly what I want. The only thing I'm really missing is TTL flash metering. I do have an old handheld flash meter, but instead of using that I'm simply taking a frame with my Nikon DSLR and making manual flash adjustments looking at the histogram, then moving the PC cable over to the Bronica.

(50,557 posts)"Auto aperture" is on every SLR in any format since the Nikon F came out, including your Bronica. It leaves the aperture at full-open position until the moment of exposure, then stops it down to the aperture set on the F/stop ring while the mirror is rising during exposure. The alternative is "stop down" aperture like you had on a Contax S, where you focused with the lens set to maximum aperture then turned the ring to the stop you wanted because the finder got darker as you stopped down.
If the viewfinder stays at the same brightness regardless of aperture setting, your auto aperture is working properly.
I"m a bit confused here tho...you're only getting 10 shots on a roll in 6x6 format? You should be getting 12; is your back working right? Ten on a roll is what you get from a GS-1, Mamiya RB/RZ or Pentax 67, which shoot 6x7 format.
Major Nikon
(36,827 posts)I'm confusing auto aperture with auto exposure. It's been quite a while before I've had to think about such things. I am familiar with stop down metering.
IIRC, I only got 10 exposures off my first roll of film. When I looked at the manual, it says I should have gotten 12. However, I also figured out I didn't load the roll correctly. It's been over 30 years since I've loaded a roll of 120 film, and I forgot about the index mark on the film when you load it. I'm pretty sure now that I went well past that point.

(50,557 posts)I got a chance today to shoot a roll on the new lens. Turns out that f2.8 max aperture is a blessing and a curse - I was going to shoot a couple frames wide open to test the sharpness at that setting but ISO 100 film won't let you do that on a bright day. Oh well.
Major Nikon
(36,827 posts)Either that or two linear polarizing filters stacked and rotated for the desired light attenuation.

(50,557 posts)The more pressing need is a pair of FL-D filters, one for my 105-210, the other for my 45. They will solve many problems.
Major Nikon
(36,827 posts)I have no desire to do so, but there's an adapter for it if I so wished.

You can also go from Bronica S lens to Mamiya 645
