TZ60 at 24mm

[Altruisto]

The review in Digitalversus and Cameralabs showed some nasty corners for TZ60 at 24mm. But this image in Techradar review of TZ60 is quite decent at 24mm. Do you think that there is a lot of sample variation in TZ60? I would be very disappointed.

owning a Nikon D600 with a Tamron 24-70 f2.8 VC, and a bunch of Nikon primes, a Nikon J1 but not particularly a Nikon fanboy, since I have an Olympus E-PL5, a Panasonic GX7, a Sony RX10 and a Canon S110 too!

I think it is very hard to judge the corners from that image. The corner softness at 24mm shows when you have a completely flat subject with detail in the corners. That can be seen in the chart tests I posted here: http://www.dpreview.com/forums/post/53482126

Also, the uncorrected 24mm RAW image shows the barrel distortion that is corrected during the JPG processing, as shown here: http://www.dpreview.com/forums/post/53482351

Thanks Ian, I've seen these before, but I think the soft corners depend on the focusing distance. Things seems worse at close distances as in your test, but seem to get better at infinity or longer distances. Look at the second sample. There are details in the extreme corners.

t’s true that barrel distortion is worse at close distances. However, I think you need to take DOF into account as well. Several of the Cameralabs images that were taken at 24mm show OOF backgrounds as the focus was close.

I could only see a corner crop on the Digitalversus review showing the distortion, but not any other 24mm sample images.

How bad it is, how obvious it is, and how much it detracts from the image is very subject matter dependent. In any case, stopping down to f/5.6 improves things a bit, and doing so shouldn't be an issue for most wide angle shots.
