Leica Screw Lens for M3

[ferider]

How do the new CV LTM-M adapters not work w/infinity locks? I thought the only change is more metal (like the original Leitz adapters) to allow 6-bit coding. As far as the mount is concerned, there is no physical difference between a lens w/an infinity lock & 1 without.

Yes, there is George. I had a Nikkor 35/2.5 that only worked with adapters with a deep cut-out (from around 4 to 8 o'clock) due to the lock. Some Leica adapters have this, some don't. Not sure about CV. All my Canon lenses work on all adapters, the infinity lock has more distance from the adapter.

More issues due to infinity lock on some Nikkor wides:
- they do not work with some ER cases, like newer Zhou or Luigi cases because the leather is too thick.
- they only work on old Ms due to the frameline selector being in the way on newer ones (the shape is different) ....

Best,

Roland.

My name isn't George, but I stand corrected. That certainly explains payasam's statement because the newer CV adapters can be 6-bit coded precisely because they don't have the deep cut-out. It also provides an explanation for having the cut-out in the 1st place (I was always thought it was just to save on materials).

AFAIK, none of my 1/2 dozen or so TM lenses w/infinity locks (including a few Nikkors, but none wider than 5cm) are different from those without & I have a mix of adapters with & without the deep cut-outs. Will have to take a closer look. 😉

The Nikkor wide angles also do not work with some ER cases, like newer

Sorry for using the wrong name, furcafe anonymous 🙂

I must visited to local camerashop to buy an adapter, before my order arrived. There was japanese ones (new) and one Leitz (old). All was prised 39€. I shooce Leitz but now reqognice it have quite much loose towards the body (Bessa R3A). Is that usual to Leica M bayounet when old?

First film from Bessa is drying. I hurried becauce second hand Bessa seller need to know, will I keep that camera. ( Bessa is not weared, that's sure.)

Buying screwmount lenses for your M3 is a good idea, especially when you eventually break down and by a Leica screwmount body.

Can't agree. For taking pictures, an M is a vastly superior tool, and that's mostly what I buy cameras for.

I've had A, Standard, II, III, IIIa, IIIb, IIIc, IIIf, IIIg and the only screw-mount I still have I my first IIIa bought in about 1970; I bought my first M in about 1974 and never really looked back.

Then again I've ony felt the need of two new film Ms in the last 25+ years, an M4-P and an MP. I have kept both M2s from the 70s and bought and sold two M3s in that time (one a black paint body I swapped for the M4-P).

Cheers,

Roger

I suggest you to get a canon 50/1.2 lens, one that is optically reliable and clean, with an adaptor, and be very happy.

False alarm! The loose point was in my Industar 61 L/D. 😀

I like the Leitz adapters myself - their better quality is evident to me in the machine work and engraving. Voigtlander adapters are a serious effort as well. The Chinese adapters are probably OK, but the slightly noticeable roughness of machine finish would compel me to measure them carefully with a micrometer before I'd fully trust them (just a hassle).

I'd second that. I'm starting to rely on mine more and more. The 50/1.4 Canon is another superb beauty of that ilk.

...and I'd second the latter: the Canon 50 f1.4 is a great little lens which can be had for very little money (unusually so for fast lenses in Leicaland!). 😀
