Alpha 850 and Best Zoom for it
« on: November 01, 2012, 12:23:54 PM »
  I am deciding on switching from My canon 40D to Sony 850. I want a good zoom lense for my weddings and portraits. I don't want to spend all that $$ on the CZ 24-70
  Can you recommend another lens that is less expensive but Excellent IQ.  Thanks,   veteran

I have the Sigma 24-70 HSM as my walkabout on the A900 - I'm happy with it, but have not had a CZ 24-70 to ty side by side comparisons.

Gets fairly good reviews on Dyxum

The Tamron 28-75 is also a good lens.
Simon (aka springtide) actually prefers it to the CZ24-70 for portraits as it was more forgiving.

Just a thought, do the Sigma and Tamron make use of all the focus points by supporting AF-D? The CZ does. Not sure if this is important to you. Also if you are going to be changing lenses outside often the Tamron has a moving rear element for focusing which goes deep within the lens and leaves a lot of the internals exposed, not sure about the Sigma.
Buying a Nikon doesn’t make you a photographer. It makes you a Nikon owner.

It is unlikely that 3rd party lenses will support AF-D (unless the A99 and it's successors prove spectacularly popular!), but as the OP is looking at an A850 that's an issue for the future.

The Sigma does use internal focussing, but I've not checked on how this moves the elements when changing lenses
