Yes, I agree- CV65 is not really a macro, but it gives a nice close-up option when needed during general "walkaround" snaps (and that's how I use it). That's also why I'm thinking of buying a "real" macro, but I really want to limit my lens lineup, so that would probably mean I would let the CV go then...
Anyways, the comparison photos posted in the recent posts in this thread are exactly what I had in mind when I said "shootout". With all respect for Marc, I find it difficult to visualize the difference betewen "outstanding" and "excellent" .
On the other hand, shooting lenses side by side lets anyone make his/her own mind what he/she values more in the output (e.g. sharpness vs "apo-ness" in Sigma vs CV110)....Show more →
By Marc's own definition you would not be able to see the difference between Outstanding, and Excellent on line. Only ifg shot on a high resolution sensor and the original file viewed at high magnification. Extreme pixel peeping required. See below.
2.1 Rating explanation
Outstanding
At this grade you exploit the full potential of the 61Mpix sensor
Everything is tack sharp even on a 100% Crop with excellent contrast
Very few lenses will achieve this grade on the entire frame
Excellent
At this grade you reach excellent results , it is only by comparing to an outstanding lens that you can see that you can do a little bit better
This is the grade that will exploit the full potential of 42Mpix of the Sony A7RIII
Lenses at the grade are perfectly OK on the Sony A7RIV
Very Good
At this grade you still get very good result but expect the start of some softness when viewing a 100% crop of 61Mpix
This is the grade that will exploit the full potential of 24Mpix of the Sony A7III
Lenses at that grade are not enough to exploit the A7RIV at any aperture but still give good results if you don’t crop heavily in the pictures
Typically some Excellent prime will fall in this category when used Wide open
Good
At this grade the image is still good when viewed globally but lack sharpness when viewed at 100%
Those lenses are still recommended for A7III but are not recommended on the A7RIII
Those lenses are not adequate for A7RIV
Average
Those lenses can barely achieve very good results when aperture is closed down and in general they are not even on the entire frame
Well when it comes time to sell your CV 65mm let me know. At the right price I may be a buyer. I fear I may be developing an unhealthy attraction to Voigtlander lenses. I may need a 12 step program or something..

Thanks, that's exactly what I was talking about . I actually missed the release of Laowa 25mm, indeed it looks really nice... My main gripe about Laowas is the complete lack of EXIF .
No problemo If I compare Sigma with VC, I'll publish the results.
If you need a macro lens I'd leave the VC 65 and add the Laowa 100. I think it's at least as good as the Sigma 105 in 1: 1 scale, plus it offers a 2: 1 scale.

Not my car carrier! A few more... A few were done in crop mode, I remapped the lens button to something more innocuous. I had it set to switch between FF and APS-C but I kept bumping it and switching.

That's one thing that's nice about having Longwood Gardens close enough for a day trip. No matter how cold it is, the conservatory is like walking through a magical portal to a place where there's greenery and flowers everywhere.
So I think I remember some concern that having so many elements would make it more prone to QC problems. I haven't done my "normal" tests, but I believe mine is well centered. Anyone get a dud? I know there's only a few people on this thread that have the lens, but I haven't seen anyone complain that they got a bum one.

Quick test macro. the test shows who is in charge in this matter. In distance, Voigtlander seems to be the sharpest. Maybe I can post some photos later.
Laowa 100 @2.8
Voigtlander 110 @2.8
Sigma Art 105 @2.8
All photos taken with Sony A7 mkI. JPEG straight from the body. Same settings.
1: 1 scale. Crop ~ 90%

I don't know, I recognize that these are not full resolution images so I am not seeing the true output from any of them.
The Voigtlander seems to render the color a bit darker giving the impression of higher contrast and sharpness. But when I look at the detail in the fibers, it looks like the Sigma shows more detail and texture.
As Sony Alpha Blog says there testing showed no meaningfull difference at f/2.8 between the CV and the Sigma.

You're right, the photos are not in full resolution, but in the crop, close to 100%, it's best to see the differences in details. As you write - they are all amazing in terms of resolution
Dustin Abbott says the differences are. I think it's a copy issue...

And that is a lovely shot for sure!

Thank you, Karl! For sure I'm having lots of fun with it. The gentlemen from Sigma who decided to address the lockdowns (and incoming ugly weather here) through offering a great macro lens are geniuses. The 105mm has definitely become my most used lens these days.
P.S. And handling all those liquor bottles can lead only to more entertainment lol
