What lens to get with a Sony a77 body

The Sony a77 comes with a 16-50mm f2.8 kit lens which seems to be very good but I was thinking of just getting the body and a better lens. The only ones I can find with equivilant zoom are either the Sony 16-35mm f2.8 ZA Vario-Sonnar T* lens or Sony 24-70mm f2.8 Vario-Sonnar T* Zoom Lens.

Do their quality greatly outweigh the kit lens?
 
The 2 Zeiss lenses you mentioned are around £1400 each. There's no way it's worth 'paying' £900 more than the excellent 16-50 f2.8 kit lens.

The 16-50 f2.8 SSM is much better than the usual 'kit lenses' you get. It actually gets the same average mark for sharpness on Dyxum forums as the 24-70 does!
 
Sony 16-50mm F/2.8 is a fantastic lens.

Fast focusing, silent, well built and sharp.

Because the A77 is crop the 16-50mm makes a great companion over the 24-70 variants.
 
Indeed, the 16-50 f/2.8 really isn't a kit lens as such, it's £550 on it's own, and for that price, the quality is excellent.. Bought as a 'kit' you get a healthy discount on the lens which is probably why it's so

Some people often look at the CZ16-80 f/3.5-4.5 which has almost identical performance to the 16-50, but you get the extra zoom length, sacrificing the low light f/2.8.. And the 16-80 isn't SSM (so not quite silent focussing in video, and possibly a little slower focussing?)
 
The 24-70 is a full frame lens though. So if you're not looking to go full frame in the future i'd stick to the 16-50mm.

Vignetting isn't really a problem though is it? It's very easily taken out in post.

I think the 24-75mm true focal length of the 16-50mm is nicer as a single lens than having the 36-105mm of the Zeiss on a 1.5 crop camera. Having the wide angle, at least for me it was, was much more versatile.

There will be some aspects of the Zeiss lenses that are better than the Sony 16-50 f2.8. I don't think it's worth paying the extra premium for though.

I'd much rather get the 'kit' lens and something like the Sigma 70-200 f2.8 OS HSM for around £900 (or £1500 for the Sony if you can stretch that far). That'll be a great setup.

That's true. With regards to a prime lens would the Sony 35mm f1.4 G or Sony 50mm f1.4 lens be more suitable for portrait, group and wide angle landscape shots?
 
For a pure portrait lens the 50mm would be better. The 16-50mm would be good for the rest of those shots you mentioned.
 
Thanks. Regarding a telephot lens I have a Tamron 70-200 5.6 atm so will want an upgrade. Two choices are the Sigma 70-200 f2.8 or the Tamron 70-200mm f2.8. According to DPReview:

the Sigma's not as sharp, according to our tests, and the Tamron doesn't have ultrasonic focusing.

I'm not too concered about ultrasonic focusing so the Tamron seems to give it a slight edge.
 
David Kilpatrick made an interesting note about the 16-50 SSM on an EVF camera here

After using the Alpha 77 for a bit I realised that f/2.8 does make a significant difference to the EVF. I guess I missed this out from my test report. With an optical finder, you don't get any significant gain in brightness much past f/4, depends on the finder screen but the best ones like the A700/A900 get brighter up to f/2.8 (the grid screens) - however, they only get brighter up to f/2.8 because they are darker at f/4... etc. Modern consumer camera screens like the A580 are designed to be as bright as possible at apertures like f/3.5 to f/6.3 commonly found on zooms.

BUT EVF finders get brighter in direct proportion to the lens used, in low light. So, a 16-50mm used at 50mm at f/2.8 is passing twice as much light at the CZ 16-80mm at 50mm, and even more relative to the 18-55mm kit lens or the 16-105mm, or the 18-250mm (etc) which are generally f/5 to f/5.6 at 50mm. These lenses may be two stops less in light transmission.

That means the EVF has to apply two stops more gain in low light and you get a worse viewing image. Also, I realised that the new focusing module responds better to f/2.8 lenses.
