FWIW Eric thinks more highly of the P-series cameras than the &amp;quot;plastic Pentax&amp;quot; MZ/ZX cameras.&lt;br /&gt;<br />

What about the SF series?

Oh, btw have you managed to open the bottom plate of the P30? I'm just as curious.

I find this statement a little puzzling. This is first I have heard of a generic durability issue with a P3 or P5 variant.
Well maybe I generalized. But I have read a LOT about shutter issues with the P series. Every forums has a bunch of threads about it.

Also, I am feeling a bit frustrated since I have an A3000, a P30T and a ZX-M. All have Pentax electronic shutters that broke down shortly after I got them (and they were all pretty much freebies, that's why I got them). They were all in excellent or "like new" cosmetic condition, so these cameras were never abused. They just broke down because they were engineered to only last a while (plastic mechanisms in the shutter).

In the meantime, my Minolta XG-M keeps reliably working (and there's reports of that shutter giving problems as well, but so far, so good thank God). To the point that I'm now thinking about investing a bit more in Minolta lenses... KEH's inventory has been pretty much depleted after the A7 came out. Maybe I should get some before they're all gone!

Or... Perhaps I just need to get me a KX or KM...

Christian, since you are close to Atlanta, I recommend you buy the stuff from KEH directly.
They are nice and since you are close enough you can pick the stuff up and they can help testing the equipment before you buy...

I guess I don't frequent those other forums. The rule of thumb with electronic shutter cameras is that they will fail when the electronics fail. As for your cameras, the issue you are having with your P30T is a problem with film transport, not the shutter. The two systems are interlocked, but quite separate. I don't remember your issues with the A3000 and ZX-M, but given that both have motorized film transport, I would not be surprised if there were issues with that system on those cameras as well.

Very few (none?) of the shutters on that era of cameras were made by the camera manufacturers. The same is true now. The two main suppliers of electronic shutters were Copal and Seiko. Both are very reliable and plastic was not part of their construction. My Ricoh XR-2s, for example, has the same shutter as in the Nikon FM. It is my understanding that the Pentax cameras had Seiko shutters. Your Minolta used a horizontal cloth shutter design that may very well have been made by Minolta.

I stand by my assertion regarding the P-series Pentax bodies. I may not be remembering correctly, but I do believe that your problem is the first report on this forum of a P-series failure since I have been active here (5+ years). They were relatively inexpensive new (priced below the top-end A-series), but are not junk. Consider again the bullet points in my post above.

I reviewed your inquiry from a few months back regarding the A3000 and ZX-M and "most reliable Pentax". The advice given there was good.

KEH tests and often refurbishes everything that goes out the door. They also warranty the purchase. They currently have a ME Super in EX condition for $49 USD and a Super Program (also EX) for $59.

I've bought stuff from them before, but you can't go and pick anything up. They only sell via mail. I've called them about this before.

But I still might get a camera from them, we'll see.

Again, these were all freebies (or came free with lenses). So I shouldn't be complaining. But I'm surprised at the high failure rate. Of the 3 cameras, the P30T is the only one that actually seems like it might be easily fixable - the shutter might be working and this might just be a problem with the winding mechanism. Probably still not worth the cost of fixing (especially considering something else might break right after, with my luck...)

Edit: the plastic moving parts on the ZX-M are on the motor, so that seems to be the common trend here... the courtain doesn't seem to want to go back to its position unlike in my A3000 where I can touch it and it goes back. And the mirror is in a halfway position, which is also weird, but it could point to a shutter mechanism failure. With the A3000, the mirror was either all the way up, or in the correct position.

Ok, an update on the P30T. I'm able to test it without film now (I don't know why, but when I got it it wouldn't work until I put a film in it...).

It cranks right about 80-90% of the time now. Only every 5-10 windings, does it seem to skip a frame and I have to wind it twice before I can trigger the shutter again.

The shutter sound seems to have gotten louder though (an ugly metal clank!), and the mirror seems to move quite slowly compared to the Minolta and my digital Pentax. If I remember right the K1000 also had a faster moving mirror. Maybe if I keep playing with it, the spiderwebs will eventually fall off and it will work most if not all the time? I'm hopeful

Another P30T update!

I've shot over 50 frames now (with no film) and every time the winder is working right! I'm starting to feel confident about putting some film in this camera.

I've verified the light seals in the mirror cavity (is that the term?) and the back all look good! So I might be able to use it for a while before I have to CLA it.

I'm excited! The ZX-M was my first choice because of the 1/2000 shutter speed, but the P30T should work with my DA 35!

Great,
IIRC the P30 only has foam on the mirror and in the film-window... doors were grooved (a la Zeiss) to avoid seals

Yeah that's where I found the seals... and they look good! They actually seem easy to replace when it eventually comes to that.

Hello.

I bought my first film camera two weeks ago, a P30t, and it has the skipping shutter problem. The thing is that it works perfectly without film, but as long as film is inside the shutter only works as long as I wind the lever twice. For each time I take a picture, I lose another one picture. It's a bit frustrating, since I see that the camera works perfectly fine without film. Batteries are ok, the camera meters properly. Regarding the shutter metalic click when I wind slowly, I'd say I can always hear it. So, I don't know if this mechanical or electronical problem.

How's your unit, ChristianRock?

Mine's working great.

But like I said earlier in the thread, I spent a couple hours just shooting and winding without film. Must have given the shutter at least a couple hundred actuations. Now it works ok. Only once did it skip a frame since then, and I'm not really sure it skipped, or if I had just forgotten to wind earlier...

I did keep changing batteries, I have two different sets that I could choose from. I think the ones that are in there now are from a cheap Sunbeam set (alkalines).
