Zenit Helios 40-2 85mm 1.5|
Mount: M42 Manual

One of the legendary Russian "extreme lenses", probably the most extreme. It is so large, it does not fit the DS without modifying! The tripod ring will touch the flash bulge of modern SLRs when screwing in the lens. To solve the problem, I removed the retaining clip/spring from the M42->PK adapter. Then firmly screwed the adapter on the lens. Insert the lens like a bayonet lens. For proper and secure alignment, you'd need to drill a small hole into the base of the lens to line up with the small axial pin on the Pentax PK mount surface. (Thanks to the Pentax SLR forum over at www.dpreview.com for the hint.) I did not do drill the hole, which means that the lens is not really securely held in place: I am hesitating to modify this lens.
The lens is surprisingly sharp and useful, considering that it is a modification of some special military instrument. It is way larger than any lens I have used before and (I guess) almost double the size of the Pentax SMC Takumar 85mm/1.8 M42 portrait tele.
