Sooooo. Ive made some changes, yes the sky is still blue. Very normal but with that I have to test these out to make sure I have good copies. Its unfortunate we have to do this but lots of copy variance around. I test a lot and i usually test this wall. Its a great resolution test and I've tested literally at least 100 lenses on it. If you don't know who I am than your in luck Im a old dog with over forty years as a Commercial Pro Experience. So I grabbed the new sony 38 1.8 and thought I would test it against the Voigtlander 40mm 1.2 a very popular lens around here. I just tested it on Big Bronco between them and nothing more right now but may visit that for rendering and such. I also grabbed a Batis 18mm and you will see how good that lens really is and again the Batis 85 and i shot a infinity test.
So on Big Bronco I only do two things as I want to do as little as needed . So i do fix the vignetting so you can see into the corners. All files get a light sharpening capture base and balance exposures. So no real corrections
Also Im shooting the new Sony A7rIV on tripod with 2 sec timer in electronic mode. Im on a tripod of course.
So just checking distortion here the CV i was slightly crooked it but it does distort more than the Sony for sure. Both at F4
Looks pretty clean. The CV40 im not going to fix here but the distortion is more complex and its mustache distortion. So LR maybe better or worse not sure. If you look at the wood strip going across you can see its wave like
To be perfectly honest it sucks and its not making me happy, that type of distortion is hard to fix. Better said not going to be a good architecture lens
Again folks I own both lenses so if it sucks your going to hear me say it. Im ruthless on this stuff
Lets move on to the resolution stuff . This is where Big Bronco is at its best. Most lenses its not infinity but really darn close. My guess im about 50 feet away. I id do a infinity one also. Again Vignetting is sort of corrected. But I have a separate test as well for that
Lets move on to wide open for both lenses.
Sony full image, left , right, center
Watch light fixture in left crop. Watch center crop which is slightly left side for those metal straps. You look at Resolution and CA here folks
So going to F2.8 the Sony cleans up the CA quite nicely and its almost at Full resolution in corners but being the Pixel peeper than its a thing of beauty at F4. Thats damn good and close to the best around. Look for CA on center crop too.

In your opinion does the Sony 35, take advantage of the R4 sensor adequately?
It is a hella lot lighter and less expensive than the Sigma 35/1.2
Thanks for your testing and straight talk (telling it like it is)

I think the 35 is sucking up every pixel from what Im seeing so far. I think where the bigger differences will be is rendering and bokeh but anyone saying its not sharp than just ignore them.
Short deviation here and what is perfect on these tests . Here is the Batis 18mm at F4. I can stop at F4 and shoot until i turn purple. Flat out outstanding copy
Good news for Guy. I got a excellent copy of the Sony 35 and Batis 18. Ive been really bloody lucky for awhile on copy variance. The photo Gods are paying me back for going through 5 Sony 35mm 1.4 lenses
I actually give the Sony the nod here. Bit surprised as the CV 40 is actually stopped down. But I always said it was a F2, but major plus for the Sony wide open.
Let me do F2 and wrap up these resolution test of BB
So I have the sun pretty much right behind me so the sky is getting full sun angle on it. Now to be fair Im in the freaking Desert and it dont get any brighter than this.
The vignette is a little too heavy IMHO but i do like some just think this is a little much. Its not a hard fix in post. But certainly something to be aware of because if your in low light pushing your ISO kinda high than you may pick up noise in those corners. So a precaution here. I tend to like it but im weird sometimes too.
