This is a very suitable set – the camera and lens have the same design (camera is released in 1981, lens in 1983)

Vignetting

Geometric distortion

This sample shows distortion in the vertical direction. It can be easily seen on the left side of the photo.

Coma aberrations:

Note: the street light on the photo has an oval shape, keep it in mind, please. I just didn’t find a better target for so huge focal distance.

Chromatic aberrations

Long-distance bokeh

Test conditions: the lens was focused on half distance on the scale (8m), buildings are on “infinity”-distance

Light bubbles bokeh

The lens is on the minimal focusing distance 4m, lights are on >200m (cityscape)

Minolta MD 500mm 1:8.0 RF (or Minolta MD 500mm F/8, New-MD, MD III design) – overall conclusion

Firstly: this reflex lens has only one aperture, so I didn’t need to make a lot of identical shots for test-diagrams. This factor makes it my favorite lens because the review has been taking the shortest time among all other reviews. I believe that only pinholes can be better for me.

To be serious – this is a very good lens. Or, at least, it is a lot better than I expected. Sometimes people scold it for low sharpness and for a bad bokeh. But it may be because this barrel requires an owner with a little bigger skill than usual. Yes, the bokeh with rings is strange, but not bad at all, and I can describe it as “trendy” for today – some photographers are a bit tired from the tons of creamy Gauss blurs and want to see the character of lenses.

What about the sharpness – just see the test results again. I agree that it isn’t crispy enough for professional photographers, who are working for sport/nature magazines, but for my level it’s absolutely enough – especially for a really low price and lightweight, these parameters can be more important for amateur photographers than totally sharp corners.

Just don’t forget – it’s 500mm, with F8 on wide-open, and operation with this lens isn’t easy – good weather needed, daylight needed, tripod needed, etc. In any way, the lens can be recommended for everyone who needs focal distances over the 300mm but isn’t ready for a huge professional gear.

Could you tell what mount adapter for Minolta 500 lens was used?

    Hello. It was Fotga that time, but I think any good adapter would be suitable
