In photography, many fantastic lenses dramatically expand any creator's possibilities. Unfortunately, not all of them are naturally compatible with your primary camera... My workshop allows everyone to correct this injustice for everyone. 

Dear Leica M camera owner! 
I'm happy to offer for your bidding:
an excellent condition 
customized 
full-frame 
rangefinder-coupled to LEICA M camera 
17 blades aperture 
black edition  

BIOTAR T f/2.0 58mm lens 

This is an original vintage BIOTAR RED T f/2.0 58mm lens from the famous CARL ZEISS brand. The barrel was customized and adapted to any Leica M-mounting and mirrorless cameras. 
The rangefinder of any Leica M(1, 2, 3, 4, 4-P, 5, 6, 7, 8, 9, 10, CL, type 240, MP, etc.) cameras will fully work with the lens. Of course, any other cameras with Leica M mounting or an appropriate adapter will also work with the lens.

There are tiny bubbles in the lenses of the optical unit. They are transparent, almost invisible, and do not affect the quality of the image. 
 Moreover, the bubbles in pre-war Zeiss optics indicate the highest quality of optical glass. 
 To achieve such properties, glass had to be kept at very high temperatures for a long time to dissolve the metal additives completely. Bubbles became a side effect; they are also a sign of quality.

All customization works were performed in my associated workshop by a high-level professional.

The optical performance of this lens is 10. The glass is free of haze and fungus, has no dents, and is as clear as a 70-year-old lens can be. Operational micro-scratches and small dust particles are possible without obstructing the image. Zoom movement is smooth, and the aperture adjustment ring mechanism is concise—no scratches, bashes, or dings of the barrel. 
Please study the high-definition photos closely to evaluate the condition, as they are essential to the description. 

The stopper ball was removed at the request of the video-filming fans. The aperture ring rotates smoothly without clicks. 
Although this lens is not collapsible, it looks like a Leica CL owner; please don't worry. 😎

The lens has an adapter from Leica M39 (LTM) to Leica M (LM), which can be unscrewed. Theoretically, the lens must also fully work with the Leica m39 camera rangefinder. Unfortunately, I don't have such a camera to test.
Warning! The German Leica M39 camera and its Soviet replicas have different rangefinder mechanisms, so their lenses will not work accurately if switched.

The lens will be shipped by registered airmail. The winning bidder receives free tracking and insurance.

Please see my other items.

If, for some reason, you're not satisfied with this lens, I will gladly accept a return within 14 days after delivery at the buyer's shipping expense.
Although I try to describe my items accurately, it is sometimes possible to omit or overlook points that may seem unimportant to me but very important to you. I urge bidders to ask questions first, not after the auction ends!
