Default CZ lens? Advice please.

I have the sony a550 with 18-55 and 75-300 kit lenses. I have been using them a short while and often find myself wishing the 55 was a bigger number! The long zoom seems to fit my needs OK.

I've been researching a bit and see that the Sony/Carl Zeiss 1680 has some good and bad reviews.

(a bad one from slrgear: The Sony 16-80mm /3.5-4.5 isn't the sharpest lens we've tested, but out of the current crop of consumer-grade lenses available for the Sony dSLRs, it's one of the better ones).

I don't want to pay 800 dollars for consumer-quality. I'd like to stick with sony but am open. Also, My pics will only be viewed on a computer. I crop a little. Will any lens make a difference in IQ or usability compared to my 18-55?

thanks for reading and I'll be checking this thread for ideas. I'm hot to buy tomorrow.

If you can, see if you can rent the lens, and see how you like it.

OK. I'll look into that.

And I see this Tamron with a crazy big zoom range is heavilly discounted locally. Hit or miss?

It is not the great thing to have a lens with a hugh range, you give up on image quality. But they are very convenient to use. But If I were going with a magazoom lens I would go with the tamron 18-250mm for the sony. At 200mm it is a full stop brighter then the 18-200mm.

I'm not wanting a super-zoom. It's just that it is on sale now. I'm 100% interested in replacing my 18-55. A little wider would be nice. A little longer is more important. But I want to buy good stuff only.

The Sigma 17-70/2.8-4.5 is cheaper, faster, focuses closer, and is quite good.

Looking into this sigma, they have at least 3 models. with hsm, with os and hsm, without either.

i suspect the sony a550 doesn't need hsm or os but i could be wrong about the hsm. what do you think?

HSM will give you fast focus. You will not need OS with the sony.

The HSM version is only available for the Nikon mount, so it will work with the Nikon bodies that don't have their own AF motor.

The OS version isn't as good.
