And those numbers were already starting to bother me from the beginning. What I mean is:
The frame size won't work for many people, for example, it didn't work for me. I like to shoot more with the camera upright, not horizontal. I didn't want to flip the camera around and look into the shaft not from upside down but sideways to the subject, holding it in front of me. By the way, the viewfinder is interchangeable and I got the shaft (another option - prism). Shaft is more interesting, you can see a lot of popular videos on the web, where they shoot models or something else through the shaft. But there is a nuance. In the shaft, you see a mirror image of the object. It just takes some getting used to.
Now back to the number of frames. Now I will write banal things, for those who want to try SF, who have long been in the subject please scroll on. You have 16 frames. You understand how valuable the frame is in the literal and figurative sense. Because of that, you meticulously snap every shot, long adjusting the composition and focal length. Personally, for my purposes this option is difficult because I like to photograph something fast.
I can adjust aperture and shutter speed quite easily and quickly, like on any camera. By the way the range of shutter speeds is from 1/8 to 1/500. The lens was the Mamiya sekkor C 1:2.8 f/70mm. Such kit Mamiya 645 you can buy at this online-store.
The camera is powered by a 6V 4LR44 battery. The charge is very easy to check by pressing the red button on the right, green indicator on the left lights up if the charge is normal.
A big plus for the layman is the film installation pattern on the reel. I set the first film with ease.
The camera has a double exposure feature, I honestly didn't experiment, but I did use the toggle lever. Important! When you set the film to the first frame, make sure that the double exposure is off or you won't be able to set it to the 1st frame.
The camera was loaded with Kodak T-MAX 400 film (black and white). And that turned out to be a minus. I simultaneously shot the same thing on a small-format camera with color film and liked the results better. That is why you should choose color for your first SF film (old folks, sorry).
All in all the first film was good, the focus was minimal if any, and that's the most important thing!
Mamiya 645 is a good first step into SF. Of the pluses:
It's pretty compact, even though it sounds weird. Easy to handle, everything in its place. Interchangeable viewfinder shaft/prism.
Speed of operation with the camera (applies to beginners). Thought I'd write more about the 1/500 shutter speed is minus, then I thought, why the SF should have the shorter shutter speeds? I was confused by the mirror image of objects in the viewfinder. The frame size is 6 by 4.5 cm (you get horizontal frames).
The number of frames! And this is the most important thing about this camera and the SF. Do you want to cut your clip even further for the sake of creativity? This is a rhetorical question, because everyone can create with any technique. If you like meticulous process, this camera is already waiting for you in this store.
About all the nuances you will encounter, I have tried to tell you. I can't compare the Mamiya 645 with other cameras yet, because I don't have enough experience yet. SF isn't easy, but it's malleable. I'll stick with the small format, but time will tell.
