This is a 28mm lens from the old Mamiya Sekor 1000 DT. It works fine and gives an interesting look. The lens gives plenty of interesting flare. It is heavy and not near as versatile as the kit lens, It is a fun but not must have lens for a Micro Four Thirds camera.
This lens belonged to my grandfather in Los Angeles. It has already seen dependable service on his Mamiya Sekor 1000 DTL. It has also been put to good use on a Nikon D3000 and a Nikon N90. It is now happy on an Olympus E-PM2. Not bad for late 60's/early 70's era lens from a pawn shop near Watts. Who knows the story of how it got to the pawn shop to begin with all those decades ago...
This is a 135mm lens for the Mamiya Sekor 500/1000 TL/DTL. It is very affordable. It is a fun lens to use. It is over sized for an Olympus E-PM2 camera. That said, the Olympus 40-150mm kit lens is a much more practical lens for many uses. Verdict - fun but not very practical.
The Helios 44 is a very common lens from the Soviet Union and Russia. The design is based on the Zeiss Biotar. This is a recently manufactured version. Like the Industar 61 and Mir 1B below, it was purchased from the MoscowPhoto store on EBay. This lens is highly recommended for a Micro 4/3 camera.
This a a nice Soviet lens that focuses very close (not macro). It is derived from an old Leica design. The brand Industar is a family of Soviet lens of 4-element/3-group lens construction. It is an excellent close up/short telephoto lens for a Micro 4/3 camera. It instantly became a favorite lens. This lens is highly recommended for a Micro 4/3 camera.
I got this excellent lens from my grandfather. It is my understanding it was bought in a pawn shop near the scenic Watts neighborhood of Los Angeles around 1970. It was this kit lens for a Mamiya Sekor 1000 DTL. It works very well to this day. This lens is highly recommended for a Micro 4/3 camera.
This is one of the standard lenses for Mamiya Sekor DTL 500 and 1000 35mm cameras. It came with a Mamiya Sekor 1000TL at a yard sale for $5. The following photos were taken by this lens on an Olympus E-PM2 camera. This lens is easily found online in good condition for very low prices. It makes a great short telephoto prime lens. This lens is highly recommended for a Micro 4/3 camera.
The Mir 1B is a Russian lens, based on an old Carl Zeiss Flektogon design. The following photos were taken by this lens on an Olympus E-PM2 camera. Interestingly, the continuous aperture ring is reversed on this copy. F16 is marked as F2.8. F2.8 is marked as F16. The lens works in spite of this quirk. This lens is highly recommended for a Micro 4/3 camera.
