Chinar Lens Sticks But No Ricoh Pin?

magkelly · 11-29-2010, 04:08 PM

After looking at this then looking at a Chinar I just picked up in a swap I'm puzzled. I honestly cannot see anything on this lens that looks like the dreaded pin as illustrated on this site BUT the lens sticks on the Pentax ME-Super anyway. It does come off but it's a bit hard to remove. Note, it also came with a really crappy Tou/5 Star zoom and that comes off the camera just fine.

It's a Chinar 28mm 1:2.8 #7061012 lens.

and here's the nice toy the lens came with....

I'm probably keeping the 28MM if it's not a Ricoh that will stick on my *ist but I'm not sure about the ME yet. It's cute, but I'm not crazy about the buttons versus dial bit.

Am I just missing the pin? I thought I knew what it looks like but I've admittedly never run into a Ricoh lens before.

Even if it had a Ricoh pin (and it doesn't, it's straight PK) it wouldn't stick on a ME Super. Ricoh pin lenses are only a danger to Pentax AF cameras. Check the aperture lever and make sure it isn't bent. Also check the flanges on the bayonet and make sure they aren't bent.

Now that I look at it it aperture lever does seem to be leaning a bit towards center. Safe to tap it and straighten it with a small hammer? Would that likely do the job?

I'd rather twist it with pliers? The impact from the hammer might wreak havoc inside the lens.

Got pliers and I'll give it a shot. Hope I don't wreck it. I'd like to actually keep this lens. It would be my second 28mm in the trash bin this week if I manage to mess it up! I've already had one lost to fungus on the Sears camera someone gave me.

That worked fine, thanks! It's much better now. I just took a couple of quick pic of the cap sans a flash on my *ist and it's not bad. A bit fuzzy, but the light is pretty bad in here and I should have used a flash really. No after editing here, except for tweaking the white balance and contrast just a bit. Probably will be better even with a good flash on or plenty of daylight. I may just take the *ist out tomorrow with just the 28MM on to see what it can do under better lighting conditions. Plenty of holiday decorations out there to practice on and I might actually have some time tomorrow to take my cameras out. I want to see if the ME Super actually works for me, how it feels compared to my SPII.

Glad to hear it works now :-)

I have a Chinar 35mm f2.8 lens with a mount virtually identical to your 28mm. The lens is well built and makes nice pics for little investment. Have fun with your Chinar.
