It's not really bad actually maybe okay . Maybe try something at like 30 ft or so might be better and try and get full sun. It's not a wrap it up in the box and return in 5 minutes, it's worth another test. The good news we are not dealing with the VC15 as we only seen a small amount of this on the 21
Hey guys, just wondering what the steps are to take that test?
I read one way online and thought I'd check it with you. Apparently you compose with an object / area of detail in a corner, and focus to that. Then after taking that photo, flip the camera upside down so the same object / area of detail appears to be in the same corner, but because your camera is upside down it's actually using the opposite corner of the lens.

In this picture I focused in the centre first and then moved the focused target in every corner and took a picture. All pictures were taken with aperture 2.8. I have just included the cut out area from the corners in the four pictures (1:1 zoom in every corner). Would love to get opinions on the result and if you think the lens is good?
Just to compare, here is mine. I did the same kind of test - but is focused in the center on the top of the scaffold and moved the building in every corner. I think my lens i decentered (the right side) but I would like to take a new test to confirm it. What do you guys think? I can still send it back so I would really appreciate your views on my test?
Another issue at hand. The field curvature is starting to piss me off seriously. Yesterday I ruined accidentally a shoot when focusing in darkness with a flashlight. Two hours or work gone bust.
Yeah I was in a cave and it was pitch black. I was trying to focus stack different cave formations without multiminute exposures so I shot at f/4. Well as it turned out I missed a bit too many elements which would have been in focus with fe 16-35.
Edit: No I was not a total dumb*ss. I used flashlight to focus. But it was almost impossible to see the big picture what was focused and so on...
I got my Loxia21mm yesterday hoping that the decentering issues had been resolved in manufacturing by now. Unfortunately that's not the case for my purchase. The top RH and bottom RH is OOF compared to the LH side.
What are my options? Send it back and request another or a refund? Is sending it back to Zeiss practical from the US? I can live without it for a few weeks, a month at the outside. Has anyone tried this solution?
Sorry to hear that. I can vouch for sending a lens to Zeiss for service (of course, customer service attitude may also vary...). They did very nice job fixing my blurry classic Distagon 21mm. Swapping for new copy might work if you can get it in reasonable time.

I had similar issues with my Loxia 21/2.8. Instead of sending back to the store, I decided to ship it to Zeiss USA.
In about 2 weeks, it came back and it was perfectly centered.

After trying to return the lens to Zeiss for realignment I failed.
The official declaration from Zeiss in Germany is- Thanks for your feedback.
We never had any de-centered lens of this type. All problems were caused by focusing issues.
So there you have it folks. No problem with the Loxia 21mm at all, ever. You were obviously not using them correctly and all the problems were your fault.
In all seriousness I wanted to send it back and have it fixed as did Fred. I think Fred got the excellent service response from Zeiss he did because he has a photographic forum with a few hundred thousand members.
I will continue to use my Distagon 21mm and although I love the Loxia size I don't consider it worthwhile buying one until Zeiss get their act together because it seems right now they are in total denial.

If I were you I'd just fill out the repair form and send it in. It doesn't say you have to contact them first. I believe this is what others have done who got theirs fixed.
That was my advice to him. Fill up the form, upload some images showing the issue and send it in.

I picked up one a couple of days ago and took pics the day I got it and the next day and checked my results in LR and they did not look great, comparing it to the 16-35 the Loxia seamed worse! Think I got a dud so I returned it to the store (7 hours of driving included ).
I had a call from the Camera Store in Calgary advising me that my Batis was in but I think I am going to pass on both and just keep the 16-35 because I have a good copy. I got the 24-70 GM a couple of weeks ago and this thing has the wow factor! this did not happen with the Loxia
Since I was in Toronto I picked up a Canon Pro 1000 and thinking I will sell my Epson Pro 9900 and fab out the big stuff.
Hmm. I'm going to have to send a letter of appreciation to the photographer who tested my copy for a couple of months before deciding he'd rather have the GM 24-70. It's very well centered.

I find the response you received from Zeiss to be very surprising as my 21 was de-centred whenI got it and I sent it back to them in Germany (through my dealer) and it came back 3 weeks later saying it had been serviced and adjusted and is now perfect. As I said I sent back through my dealer along with a CD of test images Which he also saw and thought there was an issue
The same object four corners testing method is wrong according to Zeiss. I photographed a grain silo and sent in the the good and bad corners. Here's the reply.
Thanks for sending the pictures. Unfortunately, it is not possible to compare two different pictures with different objects in different distances. Please provide ONE sample image with details in the same object distance on the left/ride side/corner. For best performance of 3-dimensional objects across the whole image field, stopping down the lens at least to f/5.6 is required. To compensate the unavoidable curvature of field of a super wide angle lens, we strongly recommend to perform a "focus-bracketing" and select the best result, instead of focusing perfectly to the centre of the image only. Please provide a different sample image for a further evaluation.
I'll stick with my adapted Distagon 21mm until Zeiss quality control improves.
As I've been using various Zeiss lenses for many years I think I can just about manually focus myself.
