I actually like some vignetting sometimes. Our Loxia 21 does a lot as well.

C1 still needs to support the Loxia line

I'm going to post today the Big Bronco wall test I shot for Fred the other day before I sent it to him. I wanted him to do his testing first. No seems a good time to show you those corners. This time I went to the very edge with building in it so you can see it. I'll post the raws also for download that way if you get a 15 you have something to compare your with. Sound good

Yes and from Zeiss charts I've seen, the Batis 18 won't be any different. The Distagon 15/2.8 in comparison has probably the same level of vignetting at f/2.8 but improves drastically when stopping down. By f/5.6 is practically gone.

The vignetting from the CV 15 and Loxia 21 only improves marginally by f/5.6.
The Canon TS-E 17 has the best ultra-wide vignetting performance by far. (with its bigger image circle)

Like I wrote, vignetting is correctable but there is a noise penalty towards the corners. ETTR helps a lot.

Just got mine, and my initial gut feel is that it's no Choppy. But I have to figure out when I can do some controlled testing. Unfortunately with my schedule, I'm not sure when that's going to happen.

Hi Tim,

Sorry you and everyone are going through such a tough time in getting copies with sharp corners.

Certainly not a way to win friends and influence people.

Big Bronco Choppy test. I did apply CA correction and I did clean up the vignetting. Closer up F8 at distance this lens actually is great at 5.6 . Kind of makes sense. F11 it is starting to diffract. Not surprising at all

A noise penalty and if you are really pushing things you can get color issues as well (not due to the lens, but due to pushing the shadows in the corners hard). I've only occasionally run into this, so it's not a huge problem all the time.

I just balanced the exposure on the cowboy rider and let the file go.

You can do that with the raws to see the vignetting on your computers

Regarding vignetting and CA for the new E-mount.

A lot of new E-mount users could report good performance on these areas but we have to keep in mind that they may have in-camera corrections being applied.

I'll attempt to do a test on my M-Mount version III. Now I'm curious . . .

I'm keeping my WATE (espeically now since I have an A7rM V3 plus a second stock A7r on its way) with all of you having potential issues with the CV15 III, Loxia 21, and the Batis 18.

My ZE 15 and Loxia 21 are both great. If it turns out the CV15 is a bust, it's not the end of the world for me.

Hello, thank you all for the contributions, I'm new here but I must give my feedback: This rolling thread about the Voigtländer 15mm (E-Mount) is very interesting. I got my copy this Monday (25th Apr) here in Switzerland. Saddly it has the same soft corner issues (with ILCE-7M2) as FM copy. But I noticed that straight lines going from center to cornes are sharp all the way but circular corner lines are very soft. Otherwise very nice lens, to bad that the manufacture can't deliver constant quality, Choppy is the reference :-) Here link: V15mm at F4.5, crop, upper right corner: https://drive.google.com/file/d/0B8y5Up2Dw1BMUnNTNGlQNmUtRHM/view?usp=sharing

Fred, thanks for all the testing you have been doing. This 15VC maybe the last piece of puzzle I go back to Sony alone with 24-70. I had VC m version, it is not good even on 18M m9 for the corner.

If I sell D810 to get A7rII, I will keep my 14-24 until I am sure I knock down a good VC15 and VC10 later. My copy of 14-24 is great. Far better than VC15 I had. I am happy with D810 but would like to have some weight saving for upcoming trip.

Anybody know how sony's new 70-300 doing for landscape? I am not entirely happy with Sony 70-200f4 I had. Plus extra reach to 300.

Thanks.

There were always forum members insisting their CV 15/4.5 III lenses were excellent even towards the corners. I used to think...."what's wrong with these people!"

You were one of them Viramati and I believe you probably got a good copy as well.

A while back I posted crops comparing it to the TS-E 17 and FE 16-35/4 and the CV could not even compete. It was excellent in the center and mid-field areas but starting at the corners towards the edges of the frame, it would fall apart.

Guy's copy performs way better than the my 16-35/4 @16 and similar...Show more →
