Converting from Canon to Sony - Lense equivalents.

(1/3) > >>

captaint:
I am currently the owner of a Canon 450d but with a baby coming along in 4 weeks I want to upgrade to a camera that also has high quality video (with automatic focus) - so I'm opting for the brand new Sony A57.

Currently with the Canon I have a great all round 17-85 lense. Understanding that I need a lense that will allow the Sony A57 to use auto focus in video mode, and that I want to get great shots of my new baby but also be able to handle anything that comes my way, what's the best equivalent Sony lense or lenses?

Thanks in advance!

Ask on a Sony forum, maybe?

I would recommend you one of this two´s haven´t found anything else on the Sony Homepage;
Both works with full time Autofocus; but you have to know that these lenses aren´t cheap; alternate you can look on SIGMA or Tamron, both should also work with full time Autofocus; As far as I know. At least it worked on A55, which i saled very often when i was a Seller; Sorry that it´s German but you will find it also on your Sony Homepage;

The quality from first one should be like standard 18-55 bit with both wider and longer zoom;

By the way the autofocus on the A Series isn´t that like on Nikon or Canon, we learned between the course (for A55/33) it don´t have Contrast AF, which mean it won´t be as sharp or as good as CANON or nikon ; so it was told to me; But maybe they have changed it in A57

Hope i could help you.
With friendly Regards
Colin

Isn't the Lumix GH2 ok for AF? But really, I think a camcorder is the way to go for decent AF at a reasonable price. Or, if you want it to look more cinematic, use any video-enabled DSLR & loupe and learn to turn the focus ring. It's not that hard!

I think his point is he doesn't want to have to think too much, because he'll need to be paying attention to his new baby. So, adding in a loupe & having to worry about focusing in a potentially fast moving situation (ok, not day 1, but within some months/few years).
