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

Minolta MD 500mm 1:8.0 RF aberrations


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
