Many, many thanks for such interesting information! I had been buying too many cameras and thought I had cured myself of that trait. But now I have discovered the Chinon "line" I am back into my evil ways again! :-)

Thank you, again.

Wow! Thanks for all that info, I am learning more and more since i started this thread. I do find it all somewhat complicated. My cameras hitherto have been Pentax. From that experience I had always assumed that to have a Pentax lens work on a Pentax camera with a programmed function one needed a Pentax-A lens. All my lenses up until now have been Pentax-M flavour. From what you say (if I have understood it correctly) my current Pentax-M lenses if fitted to a Chinon CP-5 or CP-7 would work under programmed mode. I wish I had known that a month ago! :-)

In my enthusiasm for my recently acquired CP-9AF, which I bought for a song, I just ordered a second one, with the 28mm-70mm and 200mm lenses. I bought mainly because the vendor was selling very cheaply and I thought it would be worth having the 200mm lens. Unfortunately, I am now beginning to doubt the wisdom of this second purchase. Still, it will be fun!

Thanks for that extra information.There is only one point on which you might, hopefully, be in error: namely, the CP-9AF lens I have (28mm-70mm) fits my Pentax MG and apparently will work (albeit only at full aperture) under aperture priority and manual modes.

Thanks for that information.

However, I am still a bit confused. I just mounted a Pentax-M lens on my CP-9AF and my pressing of the "P-corner" on the control pad does not display the usual "P options (P, Pc and Pa) on the LCD. I can select the other options (B, M and A).

So it seems that, at least on my camera, the P-options are not selectable.
I am really new to this camera so maybe I am misunderstanding what is going on :-).

Thanks for the information. Yes, if you are correct my lens looks to be of limited value with a modern Pentax digital SLR.

Curiously, the Butkus article says: "Not to really confuse you... BUT if you want a new lens.. any K mount auto focus lens will also fit and work on a Chinon in program mode!... you just have to manually focus". So, according to that, program mode will work for Pentax K mount auto focus lenses on a Chinon but NOT for this Chinon K mount auto focus lens on a Pentax. Sometimes life gets confusing.

Thanks for replying. I think the following "For Sale" item on the web would provide the information you requested.

Chinon CP-9AF set complete 2 lenses and flash unit . Rare to find in nice condition with manual. – Wide Angle

I think you are correct about needing to manually focus. However, according to the Butkus website (for which I have high regard!) the lens should not damage a modern Pentax SLR.

I recently bought a 1988 era Chinon CP-9AF, with a 28mm-75mm autofocus zoom lens. As most will be aware this camera has the Pentax k-mount: however, I am not sure of the "flavour" of the mount. The autofocus is clearly by a motor in the lens, not in the camera body. In contrast, from the following link it seems that Pentax digital SLRs did not get "in-lens" autofocus until the KAF3 mount, in 2007: The Evolution of the Pentax K-mount - Articles and Tips | PentaxForums.com.

My questions are:
- Will my 1988 era Chinon 28mm-75mm autofocus zoom lens actually autofocus if used on a modern Pentax mount (KAF3 (or later)?
- Will the program exposure modes of my 1988 era Chinon 28mm-75mm autofocus zoom lens work with a modern Pentax mount?

I can hardly believe that Chinon anticipated in 1988 what Pentax were going to implement with the lens mount in 2007. I suspect I shall be able to use the Chinon lens on a modern Pentax SLR but will have to manually focus. I hope, however, that the exposure modes (there are 3 of them) will still work correctly.

Thanks in advance for any helpful responses to these questions.

Well said, Lord Lucan!

I recently bought a second hand, thirty year old film SLR on ebay. The seller included the original paper user manual. Even though I had previously downloaded a .pdf version from the web I do find myself mainly using the paper manual. It's obviously much more readily available. I find the .pdf version useful mainly for when i want to do a word search.

I also find the manual not only useful but also essential, to understand fully some of the operational details and characteristics.

Many thanks for your suggestion. I shall do it!

Incidentally, the camera also can give a blinking frame count indicator on the LCD data panel. When this has happened the camera will not make an exposure. It happened for the second time today. According to the operating manual this indicator blinking, if working properly, should indicate that the multiple exposure function was in operation: in my case, that multiple exposure function was not selected.

Because I am so new to the camera I easily get really confused by any errors like that. I did clear the fault by repeatedly trying to make an exposure and eventually the blinking indicator was cleared and I could successfully make an exposure.

I shall see if the cleaning of the contacts can clear that problem too!
Thanks again for your advice.

I have just bought a Chinon CP-9AF on ebay: it arrived yesterday.

It's very complex compared to my usual Pentax manual focus cameras. It seems to be mostly functional but I think there is a problem with the 28-70mm zoom lens. I simply cannot figure out how to zoom it! It worked only once, when I first stated playing with the camera but since then, it's kaput.

I have the User Manual but it is confined to the camera itself and doesn't explain the zoom function at all. There is a ring that I guess must be used to zoom it manually but it seems to be locked solid. (On the single occasion when it DID work the ring rotated.) Furthermore, in trying to move the zoom ring from its "locked" position I may have damaged some of the electronics because if I don't have the ring in exactly the correct position (there's a bit of wiggle around the "locked" position) the 3 program exposure functions, which are toggled by a square pad on the top of the camera, will not function.

I suspect that the problem may be associated with the correct interfacing of the lens's electrical contacts with their counterparts on the camera body. That might explain why I had to "wiggle" the lens rotationally to get the 3 program exposure functions to be operable.

Does anyone own this lens? If so, can you please advise me on how the zoom should work? Does the camera need to be in a default condition for the zoom to be operated?

Thanks in advance for any advice on this problem!

P.S. Well..........I feel a bit sheepish :-). I was just being too timid. I just got the camera out again, and used a bit more strength in turning the zoom ring. It worked! Maybe some internal grease had hardened and just needed to have its tackiness broken. So the only other minor issue remaining is the need to jiggle the lens slightly, to get the 3 program exposure functions to be operable.

I hope my little early morning story has amused you :-).

Thank you very much for that information.
It's true that I don't shoot masses of film, mainly because of the associated expense. However, I do feel more comfortable with film than digital and the results are of a different quality. The only digital camera I have is a second-hand ($7) , tiny point and shoot and I use that far more than my film cameras, again because of the zero cost of using it.
I shall give more consideration of whether I should actually acquire another film camera....

Many thanks for the reassurance, 35mmfilmfan!

As a separate question, do you know if it's possible, or indeed wise, to get rechargeable CR2 batteries, with, of course, a compatible charger? My hands are small and it would be great if I could do without the grip and just recharge the CR2's when I need to.
(I did see one advertised on ebay but I am not sure what the quality of the batteries and their charger is like.

Many thanks for your well composed reply, Pentax Syntax!

The only thing that confused me a bit in your reply was that your camera was a ZX5n, whereas the one that I was pursuing was a MZ-5n. I assume they are different cameras, although I have not yet checked here in PentaxForums to see what the ZX5n is like.

Hello, all!
I am seeking informed advice and guidance, as follows:

I have several manual focus Pentax and Chinon SLR film cameras but am thinking of getting a new toy, an automatic focusing film camera. I would like a compact camera really and the Pentax MZ-5N appeals to me, despite allegations of its mechanical fragility. However, I don't like the idea of having to buy CR2 batteries all the time so I thought maybe a battery "grip" with AA batteries would be a good idea. I have never used a "battery grip", on any camera, and am not sure of the functionality.
Is the Pentax 37000 AA Battery Pack FG (grip) compatible with the Pentax MZ-5N?
Does the grip wind-on, re-wind, power the autofocus, power the metering?
In other words, does it completely negate the require for CR2 batteries?

Any positive and informed advice is welcome!

Two separate Pentax ME Super/ Pentax MG questions

Thanks very much for your reply.

Regarding the 3-in-One oil: I had inferred from online discussions that it was a "light machine oil", and that a tiny amount was the way to go. However, I shall exercise some caution. My only motivation for doing ANY lubrication is that if I leave the MG for longer than a couple of weeks with its shutter not cocked I subsequently need to wind on the film TWICE to cock the shutter. Wasted film! The alternative is to leave the shutter cocked, as you say you do, and maybe that is what I will do. One of the prominent Pentax repair gurus stated that the camera would come to no harm in doing that. curiously, another of my ME Supers does not show that behaviour.

Thanks for your reply.
I am not sure how a screw extractor works and the naughty screw that I have is a very small (JIS "00") and the "cross" has been damaged, I think by the previous owner of this camera. I am not sure ANYTHING is going to get this SOB out!

I note your reference to the camera oils: thanks for them, for my future use they seem a better bet than the 3-in-One". Frankly, at the moment what started as a tiny problem (a damaged screw) is turning into a very expensive repair exercise:mad:.

Two separate Pentax ME Super/ Pentax MG questions

Pentax ME Super question:

I had my camera fully serviced back in 2014 and have not had a film through it since then. About once a month I take the camera out and fire the shutter a few times, to keep it running freely. I left the mode dial set on 1/125 so that I would not unnecessarily use battery power. Recently the camera developed a fault, whereby the shutter would not fire or wind on until I had rotated the mode dial to another setting (any setting). Then it would operate correctly at any setting. Unfortunately, the fault became progressively worse and yesterday the mechanism locked completely. That is, I could not get the shutter or wind on lever to operate at all, on any mode dial setting. I have returned the camera to the serviced the camera but I really don't think this problem should have arisen after hardly any operation of the camera following a comprehensive service.
Any comments would be appreciated,including what could be the source of the problem and how I could possibly fix the problem myself if this happens again in the future. I don't want to keep on paying for servicing that is not going to give a reasonable period of fault-free operation.

Pentax MG question:

I wanted to give a very light lubrication of the wind-on mechanism in the base of my Pentax MG film camera. In preparation, I bought some light machine oil (3-in-One) and some expensive chrome vanadium JIS screwdrivers.

There are three JIS screws that secure the baseplate to the body of the camera. I easily removed two of the three screws but the third one would not move, despite my best efforts. I think a previous owner of the camera has damaged the screw head by using a Philips screwdriver. I can see under a magnifier that there is some distortion of the screw head "cross".

Can anyone suggest how I can remove the troublesome screw?

Sorry if this message may be slightly off topic. It does, however, address a possible key improvement for a future GR camera.

My preference in any camera is to have an optical viewfinder. I really like my Pentax ME Super but I have never owned a Pentax digital camera. The Ricoh GR, using a fixed focal length lens, seems to be ideally suited for the incorporation of an optical viewfinder.

Am I missing a trick here? In fact, are Ricoh/Pentax missing a trick here? I can't be the only simple soul who has this opinion.

Will Ricoh Make A "FULL FRAME GR" Camera In The Near Future?

Yes, for me the absence of an optical viewfinder in ANY camera is a major downside. I have a Minolta Himatic G film camera: I love it and paid only $7 for it in a thrift store. I adore it! Even with the lack of a range-finder or any kind of focussing aid the camera is a joy to own and use. Basically I would like a digital camera with the same characteristics, including metal construction, heft and the intangible "charms" (appearance, ergonomics, etc.). I have attached a picture for your delight.

So.......... like you, I find the Ricoh GR cameras very appealing, although I have never been lucky enough to own one. There are only two factors that prevent me from buying one. First, although they are inexpensive compared to digital SLRs, they are still expensive for my budget. Second, they lack a an optical viewfinder. If the GR had the latter I would be much more seriously tempted to buy one.

Many thanks for your valued comments. Food for thought indeed!
I am going to postpone any filter purchases until I see the monochrome results I get "unfiltered".

By the way, I am not a novice in photography but am on a voyage of rediscovery. I processed all my own films fifty years ago, and printed them, too.

Thanks again. I value your comments.

I have just acquired a Minolta Hi-matic AF2 Point and Shoot camera, from a thrift store. The cost was a fortune, at $7.

I really like it. It's solid, easy to use, uses AA batteries and in summary, is charming.
It has a 46mm filter thread. I never use filters on my Pentax SLR but for the Minolta I thought a Y2 yellow filter might be useful, for use with black and white film.
I note your stated preference for a yellow-geen filter. Would Y2 also be a good first choice for a filter?
Would you advise me to buy a Step-Up filter adapter, to allow me to use 49mm filters on both the Pentax and the Minolta?

Thanks in advance for any guidance!

Hello all!

I have just ordered a 100' roll of FP4+ and wanted to buy bulk colour film, too. However, the only bulk colour negative film I found online was Konica Professional 160. Konica Color Print Film - Color Films

The price is good but online reviews were not encouraging. Consequently, I have just ordered some 36 exp. cassettes of Fujicolor Superia. (I have used until now similar Fujicolor film, and it was excellent.).

Has anyone experience of using the Konica Professional 160?

Does anyone know where I can buy 100' rolls of Fujicolor? So far I have found none online.
