Many thanks Guy. You help me on with my decision on the CV15. Looks like the 21 has slightly better corners, but overall performance is similar.
The ultron with the PCX seems to be winner as well...

Anyone have questions please let me know. [/quote
I would say the 21 does have a little better corners. There a good pair though. Both very small in the bag

So a couple extra shots I did with the CV 35 with PCX and also the 50 1.2
This shot is at infinity

Bokeh Balls. With both lenses I am at MFD. I just racked myself in and out to focus and i may have missed a little but its about the Bokeh. I little mechanical looking balls on F2 and 2.8 for both lenses. Here is where the Sony seems nicer. Ill go look for that shot I did last week

Here is the Sony 24mm at F1.4 I shot last week. Very very nice bokeh

Kind of really why I bought the CV 35 is for looks like this

Center test i usually do. At F2 on both these lenses is really quite good but when it hits 2.8 its on another level

Really wide open for very fast lenses like this is pretty darn good especially the CV 50 at 1.2
But I could shoot these all day long at F2 and walk away with winners every time. We normally dont show 100 percent crops to folks. This is very critical stuff
And if you really wanted to just add a little contrast and clarity to those wide open shots and they would perk up

Thanks for the tests Guy. It's very helpful comparing these lenses side by side.
The CV 35/1.7 Ultron is an amazing lens except for the exaggerated field curvature on the Sony sensor. Luckly, the Plano-Convex front lens (5m) really helps minimize this issue. It has great contrast combined with smooth rendering. Special lens for sure.
Since Voigtlander didn't port this lens and optimized it for the E-mount yet, perhaps upcoming E-mount Ultron lenses will be re-designs for even higher IQ. We can always hope.

It looks to me like Cosina is going to make a new 35 f/2 for E-mount that ought to be pretty spectacular. We will see if that finally happens. I kind of wish they had just correct the 35 f/1.7 M mount lens, but they have been doing such a good job lately I am inclined to trust them.

Yea guys I would love this lens reconfigured for the E mount. It’s got a nice look to it. But I always liked this lens. Why I sold it before I have no idea.

Fred I agree it is nice to have a bunch of glass all in one place. May answer some questions. Also pretty much these mid range tests follow over to infinity test. Fred and I have agreed almost always when he did his infinity and I did these.
Fred if you want to test the Ultron let me know

One can always hope--but then there's this sentence from LeicaRumors about the new M-mount 35/2 prototype: "Unlike the 35/1.7, top priority is being compact while retaining high optical quality."
I'd still buy it even if it's merely very good if not "pretty spectacular."

Guy, when you say corrected on the 24GM, is that a jpg or manual correction? I thought the profiles were not out for this lens yet. Is the CA that I see on the edges lateral? I guess I'm wondering whether a profile will make this lens even better after correction.

Sorry that is me manually correcting the distortion in Capture One to what I think looks good. The 15 I did C1 and a little PS. C1 does light work not in heavy doses
I also I did not correct for CA in these tests. I want you to see it. But on the Sony if I hit the CA correction button it cleans it up right to 1.4
If you look close at the left crop the top metal there is CA all the way to F4 I believe. So try that with your Raws download. It should go away.
I try to do almost nothing on these tests. Only thing I really do is on the crops is I correct the exposure through vignetting or exposure tab just so we can see them clearly. I put a base sharpen on but it’s pretty light. They all get the same treatment
Bottom line fixing stuff does not help the viewer , I wish others would understand this and not get creative on these type of tests. Frankly I can do just about anything to these files but I don’t touch them. I’m not here to show off my wizardry but help you folks see what’s good and bad. I’m very neutral when it comes to tests.
Thanks for bringing that up. I meant to write that

Gotcha, thx. IMO the Sony looks the sharpest in the corners but does show more CA than others. I haven't DL'd the RAWs but with a profile correction cleaning that up, it should be superb!
