Hello,

I'm looking at my first real foray into medium format film (outside of a couple of TLRs) and am thinking about an original Pentax 645 w/ 120 film-back. These seems to be a really good bargain to test the MF waters, but I have a few questions that I'm hoping to get answers to ...

1. Many seem to have issues with the battery holder (not the actual grip). This doesn't seem to be a big deal, but I cannot seem to readily find the battery holders. Any tips on where one can be had (OEM or 3rd party)?
2. My vision is lacking and I really hate shooting with glasses on, so I need a diopter adjustment capability similar to the K-3 or K50, etc. Does the 645 eye-piece viewer have a diopter adjustment capability to correct for lousy vision?
3. I've read that the VF is pretty dark on the original 645's (Ken Rockwell). How bad is it and would it really present an issue with morning and golden hour shooting at mid-aperture levels (f/4-f/16, etc)?
4. Any known gotchas or need-to-knows as I consider a 645?

I'm really excited about giving it a try. Thanks for any help you can provide!!

Richard

Yes, it does.

I wouldn't say it's dark, but it might depend on the type of screen you have. I certainly had difficulty focusing in the beginning. Most of my first roll was out of focus. Mine has that split screen type which I never used before. Took me a while to get used to it. I wouldn't say it's dark though

I never noticed the 645 viewfinder screen to be dark. In fact, if the viewfinder screen had been interchangeable with the 645n, I would have swapped them to have the split-prism in the 645n.

I was able to use the adjustable diopter and never needed my glasses for shooting. My vision requires an adjustment of -3.

The battery holders get cracked. If you can get an entire battery holder, even if it is cracked, it can be made to work. Don't buy a camera with no battery holder. I don't think they are available as replacement parts at all.

I think I know which one you wanna get

Enlighten me, please...

It's some time ago since I had one, but I never had issues with a dark viewfinder, although the 645N has a brighter one indeed. But the 645 is not bad.

The 645 felt more solid as a camera than the 645N too, but if the battery holder has issues, I would not risk it. Unless it is cleaning up, but I'd ask that to be done by the seller.

The 645 has diopter correction, but do check whether it works, I seem to remember that some copies would start to slide, i.e. it would not stay in one position even without really touching it. This can be repaired I think, but that adds cost.

The EV compensation is by full stops only (so you need to use ISO dialling instead sometimes).

Otherwise, great camera. I had one, then had a 645N for the AF, but then I fell in love with 6x6 and after leaving an entire system in the cupboard for several years, I sold it. But I still remember it fondly, and I still have a 35mm 645-A lens for the eschatological project of owning a digital 645. One day.

I have a 645nII that is just taking up space in my dry box. If you want to buy, let me know, then I'll send you pictures and details. Have 120 and 220 film holders, and a couple of lenses that can go with it. Also have a box of film (expired by now) taking up space in my fridge, which I will throw in.

I'll keep that in mind for this and other reviews by Ken. :-D

Woohoo! Purchased a 645 gen 1 and a A150/3.5 lens. The 645 was from eBay and originally listed as 'no returns', but I did negotiate a 7-day testing period to ensure all seems good. It looks pretty good and the owner was very helpful in trying a few things on their end and updating via messages. Should be arriving on 2/21 and then the testing will begin. Not sure if it has a back body cover, but I have film if needed to test shutter speeds. Any recommendations on a testing process short of developing test film?

BTW -- the lens was via PF Marketplace, so I know it's good. ;-)

One more thing ...

Any recommendations on where to send Color and B&W negative 120 film for developing?

Thanks!!

Well I'm a little late to this thread as I also am a brand new 645 (original) owner. But if you're not developing your C-41 at home (Unicolor via eBay is a great choice), then I recommend Precision Camera in Austin or Apertures in Tulsa. For E-6 I recommend Denver Digital Imagining or The Darkroom in California. And ya Caffenol is a great choice for B&W.
