I had two of my 645N bodies serviced by a fellow in Arizona named Jaron Ball. One of the bodies have a film transport issue which he fixed (this was a recent purchase and I sent it off as a precaution). He did a CLA on both as well. I have a third 645N body in his shop for some more intensive work. Jaron has a youtube channel where he shows repairs being done to a 645 FA 75mm lens and 645N bodies (and other gear too). I contact him through Instagram - Login ? Instagram. He is 3D printing parts for the 645N (shutter speed dial and the battery holder) and also has designed and built circuit boards for Nimslo cameras.

I can't remember precisely, but I thought that there were three variants of this: older glass; updated coatings; and then Schneider glass (but this last version may have only been for TS in 35mm mount and not for 645). Can't seem to find much on the later versions, so perhaps this was manufactured in a small batch in my imagination.

sure, there is the TS-PC Super-Rotator MC HARTBLEI 45mm f/3.5 which is a tilt shift lens in a Pentax 645 mount. I think they also made/make these for Contax 645 and Pentacon Six mounts.

While it may not be a filter wheel, the FA 150mm f/2.8 hood has a piece that slides out to give access to the filter (so you can turn it). I think the FA 35mm has this feature too (I sold my copy) as does the FA 45-85mm f/4.5

Hi Tex,
I have the A* 300 and purchased a lens collar that was meant for a telescope, but it appears to fit the A* very well.
Also, if you are considering the FA 300MM F/5.6, then save your money and buy my FA 150-300mm f/5.6 instead -- seriously.
Hope you are well.

Sorry, I don't think there is a plethora of defective ones coming from Japan - only that folks that have bought one from there (and shipped to US) that just happened to be defective and stated they did not want the bother of having to return it or the seller offered to help pay for repairs.

I've had generally very good experience with buying from Japan eBay sellers and the few instances where something was not right, I was able to work with the sellers to fix it to my satisfaction. The ratings seemed to have changed over the last few years and become somewhat ambiguous -- but when reading carefully through the descriptions and looking closely at images and asking clarifying questions I am finding what I want (regardless of it being listed as EXC or EXC+++ or whatever they mark it as the key is in the descriptions as their EXC rating is not matching with EXC ratings from a well established seller like

One thing that does come up somewhat often are the shutter speed dial being broken off and then re-glued back on. I would ask about the history of the dials as that is one thing that I have seen and heard most with 645N / 645NII bodies coming from Japan. Not an epidemic, but if there is one thing to look for and ask questions about I would point to the shutter speed dial. The other dial seems much, much less problematic.

Pentax 645 Rear Converter 1.4X and 2X

I'll address this question -- 1. Why is 1.4X converter advertised as for the 300mm lens? Is it only optimised for this particular lens or work equally well for the 400mm lens?

Page 21 of the Pentax 645 lens manual (Note: there were many other lenses released after the publication of this manual) states (regarding the Rear Converter A645 1.4X):

"This Rear Converter can be used with not only the 300mm f/4 as described on page 20, but also with the 200mm f/4 lens."

If you have an opportunity to handle these, ideally both together (645/645N versus 6x7/67/67II) I would highly recommend it. I went down a path of trying out different medium format camera systems many years ago and while owning a few different systems over the years, I find that I use my 645N the most and it has stayed with me for over ten years now. I still have some of the other systems including Pentax 67, but find that for how I like to shoot, what I shoot, what I like to hold and look through and change settings on, the 645N fits my particular set of needs and likes best. In my opinion, the most complete and versatile system is the Fuji GX680 (viewfinders, interchangeable backs, lenses and more lenses, front standard tilts and shifts etc.), but it is big and heavy and I still find that I reach for me 645N more.

Congratulations on the Pentax 645 purchase!

There are some nice, non Pentax lenses out there that can be adapted to the 645 mount. Loads of Pentacon Six (P6) mount lenses out there, although finding a good adapter is a bit of a chore. Some nice ones to consider are the CZJ 180mm f/2.8 and 120mm f/2.8 - focal length and/or apertures not found within the 645 series of lenses.

For your 645 body (if you decide to go with manual focus glass) - try an eyepiece magnifier (flips out of the way) as well as a split image focusing screen for easier manual focusing.

Pentax 6x7 vs 645 systems Advantages and Disadvantages?
Posted By yurihuta
Replies: 60

I faced something similar to you, but over ten years ago. I wanted to try medium format and was weighing many of the factors - go big? go smaller and maybe more convenient? go in between? Well, for me there was no correct answer, although there did turn out to be an answer that worked better for me than the others (mos tof the time). How is that for a totally non-committal answer?

I never settled onto one choice and part of that has to do with timing and prices. I started off with a Bronica SQ system (6x6 and also 135mm wide) and while that was fun to use, it didn't feel ideal and so I sold that and went with a Pentax 645 original and really liked that, but again it didn't feel like "the answer". I dabbled with rangefinders: Mamiya 7 and Fuji GS645 as well as Fuji GW690. I also dabbled with larger SLR 120 film gobblers like the Fuji GX680 and Pentax 67/67II and Pentacon Six. I also picked up something more advanced than the Pentax 645 that felt best (for me) -- a Pentax 645N and some FA glass for it. That has been the camera I have used consistently and still feels right for me. While the Fuji GX680 system seems most complete to me - with lenses like the ridiculously big 50mm, the sharp and versatile 65mm and the gorgeous portrait lens 180mm f/3.2, movement of the front standard (tilt and shift) - but it is big... actually really big and cumbersome compared to the Pentax 645N and so I find myself reaching for that infrequently. I had the luxury of really low prices on a lot of this gear and was able to try out a decent amount to see if it suited me. Anybody else notice the upward trend on a lot of medium format gear in the past three, four years?

One of the big things that stands out for me with the Pentax 645N is the big, bright viewfinder and the grip. For me, the improvement in viewfinder brightness presented a significant improvement and I simply enjoy looking through it and the grip felt right in my hand, so I was more apt to pick it up and use it. That you went to a store and tried out the 645 and 6x7 in your hands is great! If you can go back and try handling those again with some lenses on them, look through them side-by-side can be more valuable data points for your decision making. Also, the layout of the 645 is quite different from the 645N / 645NII, so you might find one works better for your over the other. If the shop you visited has the 67 body and the left hand grip, that might be worth trying out too. There are also non-Pentax left hand grip available for the 67 (and 6x7) bodies that might work better for your hands.

With Pentax 645 bodies you have the ability to use the 67 glass with an adapter. The 67 105mm f/2.4 adapted (Pentax made an adapter for this purpose - readily available) to the 645 body makes a very nice portrait lens. Lot of wedding photographers are using 645 bodies with the 105mm lens. The 645 system has both A (manual focus only on film or digital 645 bodies) and FA (autofocus or manual on 645N or 645NII film bodies as well as the 645D and 645Z digital bodies) lenses available. If you pick up a 645N or 645NII body and use manual focus lenses (be it Pentax 645 A or Pentax 67 or adapted Pentacon Six etc.) there is a focus confirmation green LED in the viewfinder and you can set the body to also emit an audible beep when something is in focus.

It sounds like you have a bit of time before you will make a decision, so consider finding and attending film shooter meet-ups in your area and see if you can spend in field time with these camera systems from a willing owner.

Pentax 67 where to buy
Posted By yurihuta

When looking at gear from Japan based sellers on eBay, I have come to find that the rating system has changed dramatically in the last several years (I am USA based and am going by the rating system of KEH).

The trend I have seen (for the items I typically look for) is that what used to be EXC (excellent) from a Japan based seller on eBay [and is still EXC at KEH] is now something more in line with BGN (again, compared to what KEH considers BGN or Bargain) or even AS-IS. There are Japan based eBay lenses listed as EXC or even EXC+ or EXC++ that are described as having thin haze or small fungus - whereas that would never get a description of EXC from KEH. So I would caution you to read the descriptions closely and pay less attention to the "grade" given by the seller. Truly a case of buyer beware if you are accustomed to KEH based ratings system.

Having said that, I am still pleased with the majority of purchases from Japan based eBay sellers.

If I recall correctly, the metal hood you have should have a very small screw that you can loosen to adjust the final orientation of the hood. I thought it was a small flat head - but it has been a while since I've had that hood on my 105mm (I can see about finding the old hood in the jumble of older 67 gear I have).

Selection Dilemma: Pentax SMC FA 645 200mm f4 OR MC Carl Zeiss Jena Sonnar 180mm f2.8

I have both of the lenses you mention - 645 FA 200mm and CZJ 180mm f/2.8 and the FA 200mm f/4 is a quite sharp and very light. The problem I have with the CZJ 180mm are the adapters for P6 lenses onto Pentax 645 bodies. Of the ones I have purchased from Europe, one came apart very easily (needed to take the lens to a local repair shop (lucky me there is a great repair shop in downtown DC) to remove the remaining P6 adapter from the lens. Upon examining the other adapter, it appears there might be similar issues with it - the material quite thin compared to OEM Pentax 67 - 645 adapters. Not sure if the thinness is due to constraints with adapting P6 lenses and maintaining infinity focus or just using inexpensive material, but it is really thin and having a much heavier CZJ 180mm f/2.8 lens mated to your 645 series camera via this adapter makes me worry.

If you already have a custom mount for 645 lenses, could you get the 67 45mm f/4 and use the 645-67 adapter with it on your current board?

Failing that, have you considered the 645 A (or FA) 45-85mm f/4.5 zoom? They get better reviews than the primes.

I have a bit of experience with the 645N II and about ten years with the 645N. I have shot with the same 645N body for a little over ten years now in a variety of conditions - Andes, Amazon and the Catskill Mountains (in the dead of winter) and it just keeps on working. There are a lot of wedding photographers who are jumping on the 645/645N/645NII wagon and some have experienced issues with their bodies (e.g. buying a defective one from Japan or dropping their body) and seem to have been able to get them repaired. One repair shop that I have sent others to for their 645N/645NII issues is Bill Moretz (About Bill Moretz ? ProCamera) who is an amazingly capable technician and really good photographer too.

I used to own the 645 FA 400mm f/5.6 and currently own a 67 M* 400mm f/4 ED and used both on a 645N body (as well as trying them on Nikon DSLR via adapter). While the 645 FA 400mm f/5.6 is a really nice lens, the 67 M* 400mm f/4 ED is a truly amazing lens - note that the price difference is about 2-3x more with the 67 M* 400mm. I sold the 645 FA 400mm and have kept the 67 M* 400mm. I have a Wimberley WH-200 gimbal head on a heavy Manfrotto tripod and this works nicely along with a Sunaway Long Lens support system.
