I found a Petri lens

Anyone ever try shooting with Petri? I wish I could go out and take some pics but it is still nasty outside. Any comments on Petri? The 50 mm and others...

Petri glass is usually regarded as excellent. I have had two C.C. 55/1.8's, both excellent. One was in Petri bayonet mount and the aperture was stuck wide open. I put a PK mount on it and it was still sharp wide open. Then I sold that and got another (different formula) in M42 mount. I use it, it is excellent. Oh, did I say that Petri lenses are excellent? Yes, they are.

Yeah man, I was about to get rid of mine in m42 mount bc it had a no name ring to it but last week put it on my camera and took some shots and was blown away at how sharp it was and the beautiful bokeh it produced. I think I have one 50 mm in a different mount that I wil probably sell but after putting on that lens, it instantly went into my favorite and top lens list. Thanks for the confirmation. I know I am not totally out of my mind now. Lol. Wink

. Awesome.

i have several petri lenses and have found the petri orrikor kuribayashi lenses to be both very good and very compact. i like them better than the regular CC versions. all of mine are m42 mount. their compactness make them a nice choice on EVIL cams, in fact the POK 135/3.5 has been my mini tele indoor concert lens of choice on my m4/3 olly for quite some time now because its so tiny and rendition is so sharp wide open. i also have the POK 35/2.8, 50/2.0 and 180/3.5, which ive used to very good effect on my 5d.

I have a 55/1.8 CC and at least wide open is soft. I'm waiting since months that my father-in-law shows me his old Petri set... to see what he had used in the past. I hope in some gem Smile

Yes, please ask him now instead of making me wait for months, too! I would like to know more about the Petri lens set. My 55/1.8 is spectacular. I have other Petri lenses, but I need to go through them still.....

A penny on a petri can go a long way!

Here is my Petri camera with Petri Lens. I took photos of the camera with two different lenses. The top is from a Zeiss lens. The bottom two from a Petri lens.

I would like to know if anyone can see a difference in IQ, shot between the Petri and Zeiss glasses. Keep in mind the top two have been cropped to adjust for focal length of lens. I am sorry but I don't have the exact same focal lengths in glass for both sets. Is there a difference and if so, what?

I would like to know what kind of mount this really is? Is this really a Pentax K bayonet mount? Thanks.

No, it's the Petri mount, not the same as the Pentax K, sorry.

Well I've been seeking out hidden gems for a few years and I can't remember anyone saying "WoW! you must get a Petri lens" ...........but I'm open minded.

This guy says "your Petri lens is sharp well a bit soft wide open" erm but most nifty fiftys are Wink

.....and also interesting is:-

"Kuribayashi Petri also made lenses for other mounts such as the Nikon rangefinder, and were an occasional OEM for other companies such as Vivitar."

The kicker is the rear mount. Which mount did you get? I am currently hacking my 135 mm Petri rear to be able to use on other cameras. I have never done anything so crazy, but I am guessing it might be worth it. Through the viewfinder, the 135 mm was tack sharp on that FT body. I also love how that camera clicks. It feels so strong and sweet. Look where the shutter button is! Sweet!

I've screwed my Petri 45mm lens onto my MTL3 as a body cap and put it in the back of the cupboard Laughing

maybe I should at least try it, but can't see it coming anywhere near say a Hexanon 40mm f1.8.

I don't know man. It is a big risk. That Petri mount sucks big time. They are basically useless, the way they come. I am going to retake those pics as well, just to make sure, and be more scientific in an off the cuff way. Three trials are better than one.

Not sure if my Petri is an M42 of bayonet until it arrives. If it's a bayonet I shall attempt surgery. Anyone know what the register is for a Petri bayonet?

What does register mean? I am doing surgery on mine (135mm) and am in a limbo state wondering which rear I am going to hack on it. Something tricky. I could ask someone to manufacture mounts but that will take at least two years, but there is no market. This is the cost of this lens and why so many are just sitting uselessly on the market. I expect the prices to keep dropping because of that stupid mount in futility. I think they are worth no more than $2.99 USD. The prices some stupid ebay sellers are trying to sell them for. These guys are crazy and out of their minds! If they really want to sell them, they will readjust their prices into the junk and useless category, which is like 0.99, if at all. These lenses make great door stops.
