Good Zoom for Sony A7RII ?
deanwork:
I've been printing for a client who just bought the new Sony A7rII. She purchased two lenses, one the 50mm Sony Zeiss which was excellent and also a 24-70 zoom also sony zeiss that is terrible. I have never seen such barrel distortion on a 24 inch lens before. It's crazy. This lens is also not very sharp. I am going to suggest she return it and buy something decent, even if that is an adapter for her much bulkier but better Canon zoom.
This Sony zoom is very small and lightweight, but to me it looks like junk. I wish I had the model number with me but I won't find out until I see it tomorrow afternoon. Certainly Sony must have better 24-70 zooms than this. Otherwise this new lens is totally defective. I don't know what she paid for it either.
I'm going to look for some reviews now. Obviously with this nice sensor you want something that does it justice.

Sounds like a defective sample to me. The 24–70/4 isn't a great lens but it's hardly terrible.

That distortion is not good at all. Compared to my Nikon 24-70 it is day and night bad and this lens is just not very sharp.
This was the first review I found on it and they state the same exact feelings that I have. Way too expensive for what it is.
Verdict
Sony Vario-Tessar T* FE 24-...
Price ..
1098.00US$
The Carl Zeiss Vario Tessar T* FE 24-70mm f/4 OSS ZA didn't really convince us completely - not at this price point for sure. While it is a joy to use the lens thanks to its high quality finish and super smooth controls, the optical characteristics aren't quite as impressive. Sony/Zeiss seems to follow the ugly trend of under-designing lenses based on the assumption that digital correction will fix the flaws. This may be an acceptable compromise when decreasing weight, size ... and price. However, the Zeiss lens isn't really a hell of a lot more compact than e.g. the Canon EF 24-70mm f/4 USM L IS. Thus why is it necessary to design a lens with such massive distortions ? Now distortions aren't really a primary concern for most users but the lens is also not all that sharp - at least at the extreme ends of the zoom range. The corners are generally soft at 24mm and it's not all that hot at 70mm @ f/4 either - even with activated (lossy) distortion correction. This is rather surprising given the moderate max. aperture which should make things comparatively easy for the lens designers. The CAs are well corrected except in the corners at 24mm. The vignetting characteristic is rather typical for a full format lens in this class. However, another downside is the quite rough bokeh. Combined with the high price point, this offering leaves a couple of question marks. For sure it proves again that it isn't trivial to design a really good standard zoom lens for mirrorless cameras.
Optical Quality: (in auto-corrected mode) 2 stars out of 5
Mechanical Quality: 4 stars
Price/Performance: 2 stars

Is it really enough better than the Sony 16-80 to cost $1,000.00 more? or even $500.00 more?

i needed as well a good and especially a sharp zoom for an aereal shooting. I compared the Zeiss 24-70 with two samples of the sigma art 24-105 and the canon 24-70/4. By far the canon was the best lense, its really good. The Sigma wasnt bad too, but especially at the wide end not as sharp in the corners than the canon. The Zeiss was indiscutable bad, i would say unusuable if you want or need sharp corners. Af speed is very good with the metabones mark4 with fw 0.44.
