| Mamiya / Sekor 55mm F 1.4 Review |
I use this lens with a focal reducer. Aberrations are LESS using the RJ focal reducer from ebay seller Jin Finance. It's crisp, yet creamy.
Unde
r some conditions the bokeh may produce soap balls, as you can see above, but when it does not, the out of focus areas are just smooooooth.
There ...
| | | Revuenon Special / Mamiya-Sekor ( pantor ) 35 f2.8 Review |
This 35mm on my m4/3 camera, looks like a 70mm on a full frame camera. Wide open, it is still sharp. The corners on my copy are quite okay. When stopped down two stops, like with any 35mm or shorter is sharp across the image.
But the best feature is that the colors are so nice. I had a Vivitar 35...
| | | Jupiter-37A 135mm f/3.5 Review |
Metal body looks like it passed through world war, but inside - there are only few dust spots. Glass is in excellent shape.
Jupit
er 37A is underrated lens. A far better and more robust than CZJ Sonnar 135/3.5. Excellent sharpness wide open. Using it as close-up lens there is no color fringing a...
| | | JCPenney 135mm F2.8 Coated Optics Review |
This lens is in my family for almost 35 years now and it was s part of a two lens kit with which I started my adventure with amateur photography. Thus, I might be a bit biased in favour of this lens. There is plenty of vintage manual 135mm f2.8 lenses and this one seems to be similar to inter alia A...
| | | Novoflex Noflexar 1:3,5/35mm Review |
Excellent, relatively unknown brand that excels in optics and lens technology. Novoflex was a high end german brand that made optics and they still make optics for large format cameras, I wouldn't say it's like a Zeiss or Leica lens, but its performance is extremely good, very good build quality an...
| | | Cosina 20mm f3.8 MC Review |
I am having some mixed feelings about this lens. It has an amazing field of view but is not that amazing in regard to the image quality. I bought it for my K1000 because I wanted to do some photography with an ultra-wide lens and I was too cheap to buy the Pentax-M 20mm. This lens is apparently the ...
| | | Tokina RMC Doubler Review |
I both this teleconverter in mint condition thinking that will outmatch the simple Tamron MC 2x teleconverter that I have ,so I did test them with Tamron CF80-210mm on night sky photography , but resolution, sharpness and loss of light on Tokina RMC was much worse, so the simple Tamron MC Tele conve...
| | | Auto Flex 50mm 1:2.8 Review |
Highly underrated lens, it came with a Chinon CS I got for cheap years ago.
I think it is a Tessar design, since the images came with a look similar to the 1950s Zeiss lenses
Lots of charactwer in the images wide open, Quite sharp at f/5.6-11 and some light fallout on the edges at f/16
| | | Soligor C/D 500mm f8 mirror Review |
Lens is light and easy to handle. Sharpness is good if you can focus it properly. It could be hard because aperture only f8 and there is no focus confirmation on this lens on k-3 II. There is no shake reduction as well. K-5 worked well with it. My lens came with blend and using it significantly incr...
