Was looking on ebay for a nice F1.4 that does not cost a fortune and noticed that the Rokkor-X PG 50mm F1.4 md mount seems to sell for around 60
Is this a good lens?
I have searched here but cant find many posts as to the quality a lot about converting it do i need to convert or modify if i use on a NEX with an MD adaptor.

I confirm 1.4/58 is awesome Smile - Very good colors and smooth out of focus.
The newer 1.4/50 should be good too.
For Nex you just need md-nex adapter.

The 50mm f/1.4 is a terrific lens! Probably the most consistent f/1.4 I've used.

I sold it a while ago 'cause it wasn't a Zuiko. I know, stupid of me. But I wanted to keep my collection in a reasonable size and I'm a Zuiko fan.

My Rokkor 50mm f/1.4 was my standard lens back in 1974 and I look forward to using it again. For now, and until I spring for a NEX, I can only use it with a glass-less adapter that allows only close-up photography. It's a great lens that sits with others awaiting my future NEX. These close-ups taken with A200:

I'm very pleased with my 1.4/50 MD (Mk III). It needs a hood if you're pointing near the sun, these shots were taken before I'd got one:




You don't need to convert it to NEX, just use an adapter.

Peter: NEX isn't a conversion, it's a short register mirror-less camera similar to the 4/3, except it's APS-C. It too would require an adapter, but the adapters required to use the Rokkor on my A200 would have glass which definitely impacts quality in an unacceptable manner.

Question The OP asked "do i need to convert or modify if i use on a NEX?"

There are a few different ones, so you need to know which ones they are.

The ones with Rokkor X were the ones marketed in the USA, if I recall correctly. they are the same as the ones without the x.

There are:

Minolta Auto Rokkor - PF 58mm F1.4

Minolta MC Rokkor - PF 58mm F1.4

Minolta MD Rokkor 50mm F1.4

Minolta MD Minolta 50mm F1.4

There were a few varieties of the earlier Auto & MC Rokkors.


In my opinion, the best is the MC Rokkor - PF 58mm F1.4, then the MC & MD Rokkors together. I've done tests on all of these lenses, and the MC 58mm is sharp, almost no CA, but with a fraction less contrast than the MC & MD lenses.

The build quality is better on the MC than the MD, but the MD is lighter and looks more modern and "clean".

The Auto Rokkor series are nowhere near as good as the later lenses.

Yes, But the MC lenses aren't multicoated and are more prone to flare.
I've also seen tests that show the MD versions are sharper, but I haven't
done the tests myself so I can't say for sure that's true.

Another f1.4 option is Chinon. They come in 50 and 55mm, in M42 or PK versions and sometimes much cheaper than 60. I've never used one but my gut feeling is they probably don't quite reach Takumar/Rokkor standards. There's also the excellent CZJ Prakticar 1.4/50 for Praktica bayonet mount if you can use that.

The one i went for was this one


And i paid a lot less than 60 for this little beauty
35 to be exact

I had the 1.7 and 1.4 MD versions, the latest was a Rokkor X. Actually the Xses were the ones only for American market, optical formula was the same.

Anyway those are superb lenses, both in terms of image rendering, with a slight warm tone, good contrast, the construction is superb and their compact size is appreciated. Very good choices !

This is not quite correct. For example, ALL of the later MC Rokkor lenses with the rubber focus grip, are multicoated, including the one in the picture above. This includes all of the "MC Rokkor -x" lenses imported into North America.

The multicoating of the MC Rokkor lenses evolved over time. I haven't checked for mulicoating, but I have a number of MC Rokkor -PF 58mm F1.4 lenses, which I could check..... I can then report which serial numbers have multicoating and which ones don't. The possible lack of multicoating on earlier MC Rokkor -PF 58mm F1.4 lenses may explain why the contrast is not as good as the later MC & MD Rokkor 50mm F1.4 lenses.
Whatever the case, I think the optical formula on the MC Rokkor -PF 58mm F1.4 lenses is superior, taking sharpness and lack of CA into account.
