I enjoy myself occasionally making disrespectful lens tests with no scientific basis. But they are the same subject and in the same conditions of real life Smile

Today Osaka against Oberkochen, all photos are unedited direct JPG ... start the match!

Very nice comparison. I cannot easily decide which to prefer too.

I still don't think I am experienced enough to judge but I think Planar is marginally better. This is from a Minolta Rokkor fan. Difference in colour rendition is very slight.

Me too, a really slight preference for the planar, but give me any of them and I'll be happy.

Very interesting but a blowup crop would be nice to decide which is the winner for resolution.

I prefer the Rokkor's bokeh in the flower shot.


PostPosted: Thu May 09, 2013 1:46 pm    Post subject: Reply with quote

i also prefer that soft bokeh balls of rokkor on the flower shot

Just to nick pick: Isn't this name "MC ROKKOR-PG 55/1.7" by mistyping of "MC ROKKOR-PF 55/1.7"?

Minolta's MC/MD 55mm's are all ROKKOR-PFs.

Thank you !
That explains why i searched and found a zillion PF, some pretty cheap, and no PG....

Could the mount be swapt on those PFs ??

Thank you for your accuracy! He is MC ROKKOR-PF 55/1.7 certainly. I've fixed the title.
Happy shots!

Nothing in it really but much prefer the bokeh from the Rokkor without the outline the Planar has

Leica Summilux is better Laughing Laughing Laughing Laughing buy one 1000 USD only and compare .... (will be same than this )

Great test, it shows well, if subject , light right and smart people behind camera , basically no matter what lens do you have in 50mm focal length.

Differences usually pops up more in bad light, Zeiss will still shinny and Minolta require to fix contrast just a few click , but most people lazzy to do it.

Bokeh on the Minolta is very, very nice.


PostPosted: Thu May 09, 2013 11:58 pm    Post subject: Reply with quote

I really like both. Zeiss may be a little bit sharper. Biggest difference to me is in the bokeh, but I like both of those too. That's my "scientific" analysis. Smile

Since they're so close, maybe try more demanding conditions as Attila suggested.

Very good comparision!
Old Zeiss 50/1.8 has better colors and is slightly sharper but Minolta has better bokeh.
I would simply buy one which is better than both Wink

Price-wise I would recommend the Minolta

@Atilla Old Summilux is indeed nothing special and I guess not better than these two but the more modern Aspherical Summilux should kill both.

The rokkor is just better in bokeh!

I do not own a Planar but it seems to me that your Planar is either a Rokkor PF or you forgot to switch lenses on your camera during the comparison test. All pictures look like they were shot by the same Rokkor PF on Aperture Priority mode.

Would expect the bokeh to be slightly more pronounced on the Rokkor (10% more magnification, 6% larger aperture) but it is significant how much bigger the OOF spots are. Definitely a winner for that sort of photography.

I'm a big Rokkor fan so I had to suspend my prejudices while looking at the pictures. I think the Zeiss was better on the 1st (flower) shot but other than that I think they were about equal. And even though they're quite different I like the bokeh both produce.

Thanks for posting this test. I've done comparison lens testing for myself, maybe I'll post some of those results too.

Like Dog

A nice fun comparison. Same subjective thoughts, I like the Minolta's bokeh more, the Planar's color better. Both are very satisfactory. Nice pics.
But I think to eliminate the extra 5mm of focal length, the Minolta MC Rokkor-X 50mm f1.7 would be a closer comparison.

Say! This thread has reemerged from the depths... thanks to all for all the answers, old and new, and your good humor. I agree with most, the differences are very small or unnoticeable. But those 5 mm, as VNG555 says, give advantage to Rokkor for a softer and diffuse bokeh, which prefer almost all.

You see that the viewing angle of Rokkor more narrow than the Planar, your response indicates the similarity between the two. Smile

Please, do it. We will be happy to see it. I wait.
For my part, I thought of another dogfight, now in a FF ring, between other two, Planar 50/1.4 and Canon nFD 50/1.4... the ultimate test, the fight of the century! Laugh 1

Happy shots!

The Pf is Warmer in color rendition.

The Planar (rollei or zeiss?) is more sharp.

Neither are close to 2/50 summicron (R/M).

I had the three.

I think that the japaneses 1,8/55 are in the same league.

The summicron, Planar c/y and Pancolar, are a Step over them
