I bought both the 21 and the 28 recently and I always run this test just to see if everything is symmetrical and nothing has any issues like I had with 3 previous Sony 35mm 1.4. Im on my 4th copy of that lens and I finally have one at 2.8 the corners match left to right. Yes been through the war on that but I think I won the battle. The Loxia 21mm as you will see is exactly what a lens should be and I have a stellar copy it seems. At 2.8 both corners match and even better its even really great at 2.8 across the frame. Don't ask how but I think I have been blessed by the corner Gods but the lens is killer through the aperture range and lets call it F4 looks no different than 5.6. Now that I got your attention , you want it it will cost you 5k. ROTFLMAO
Okay that was the good news. Now onto the Sony 28mm F2 after you look at the Loxia its a little disappointing but lets put that into perspective this is 3x less expensive of a lens at US prices new at 448.00. So yea at F2 its not great across the frame and it does take a bit to get there although the lens is even in both corners at all apertures so not asymmetry issues and centrally this is a nice lens. I do like it but you want corners sharp than stop down, its just that simple. I would like folks to confirm this looks like there copy or not. I want to be sure and if not Ill return it and get a brand new one. I bought the 28mm at KEH and I have a few days to return it. So let me know what you think.
One the 21mm focus is just before the hard stop and really its really at infinity pretty much. I can test true infinity but honestly this copy is great and might just be a waste of my time.
Both lens centrally are very good and I feel no need to go through that work. But lets take a look at this test
I did Full image view of each lens than at the widest apertures i did both upper left and right just to make sure they are equal which they look like they are . Than I just did the upper left stopping down.
One issue is the hood on the 28mm is not the hood that comes with it. I never use original hoods but metal screw in hoods. The 28mm hood is to big and caused some vignetting in the extreme corners so I ordered on that will work better. Nice buying lenses from me because I never use the caps or the hoods that came with the lenses as i store them and use cheaper caps and hoods. No reason to be loosing 40 dollar lens caps and folks they do get lost at some point.
Loxia 21mm
Sony 28mm F2
I do have distortion correction on in Capture One and it did apply it to the 28mm but I don't think there is one for the Loxia 21mm yet as flipping the switch on and off caused no change
