Topic: Pentax KX vs. MX - reliability

Hello,

I bought in august a MX which asfter only one 35mm roll its shutter jammed. I'm no specialist and a servicing would cost way beyond buying another one, I was surprised to see how fragile the MX is, especially in contrast with less regarder Chinon CM4/Ricoh XR1 - KPentax mount cameras. I was wondering if, regadint the camera's reliability (both mechanical and electronical - light meter), the KX would the better. I know, KX it's bigger and heavier, and i love the MX's ergonomics (with its led lightmeter), size and all (shutter sound  ), but better a bigget camera than a non working one.
Thank you.

ps. I like a lot these mechanical cameras being able to work even if their light meter is broken, without any elecronics

Re: Pentax KX vs. MX - reliability

Hey, there.


Well, I don't have much experience (in fact, none at all wink) with the KX, but have been playing with an MX lately.

Got mine not so cheap (80 €), because it had a lot of issues, but it came with 2 lenses (one of wich an SMC Pentax-M 50 1:1.4, so not so bad wink, and it was a nice time fixing it's niggles big_smile).

Anyway, mine has jammed a couple of times (was using its winder, and I think it jammed because of low bateries in it). It did the whole shutter cicle (as far as I can say, haven't developed that film yet), but the mirror stayed up.

The way I fixed it (if it is a fix), was to pull, not the mirror, but the aperture actuator lever down, by hand. Aparently, it solved the problem, and (with fresh batteries in the winder) haven't had the same problem again (finished that roll and started a new one, so it was about some 20-odd shots with no problems).

If yours has the same symptoms, it may be a sticky mirror problem, and even with this "fix" is probably going to be a recurring issue, but it can also be a completely different problem hmm...


Not much help, I'm affraid, but if you're into that sort of thing, the MX's service manual is available free in the www.


Cheers!

Re: Pentax KX vs. MX - reliability

No experience with the KX either, but I love my little MX. Everything can and will eventually break. Sounds like you had a bit of bad luck with yours. Doesn't mean it's a bad camera though. Good luck with the further use of yours. smile

I put that adapter in a safe place, never to be seen again.

Re: Pentax KX vs. MX - reliability

If you want a a complicated mechanical device made 30-40 years ago to be reliable you should have it serviced.

Good point Chris. It is also possible when buying a semi pro model (which I think of the MX as) it has probably/possibly/maybe been serviced regularly through it's main span of service. wink
Now days it's hard to find a good camera tech for a good clean, lube, adjust, and repair. hmm

Pentax users in USA are especially fortunate to have Eric Hendrickson to maintain their gear in top working condition.
Eric has repaired numerous Pentax film cameras and lenses for me in the last 15 years.  His work is fast, accurate and inexpensive.

I as well have had numerous Pentax cameras serviced by Eric since 1999.  Most recently he CLA'ed an LX for me, but has done many more.  I eventually sell a camera and try another.  Right now I also have two like-new two KX'es.

Just the fact that you have used him more than once speaks highly of him. Thank You. smile

Re: Pentax KX vs. MX - reliability

I think you just had bad luck, my Pentax MX have survived a lot.
How about the K2? Wonderful camera (especially the K2 DMD), same shutter as the MX, but better viewfinder (in my opinion). The DMD even got exposure memory.

Re: Pentax KX vs. MX - reliability

The K2 has an electronically-controlled metal blade shutter that runs vertically.
The MX has a mechanical cloth shutter that runs horizontally.
