Hey everyone.

I'm looking for some reach and noticed at B&H they have two Bigma's listed.

Sigma Zoom Normal-Telephoto 50-500mm f/4.0-6.3 EX APO RF HSM Autofocus Lens for Nikon AF-D $939.00

Sigma Zoom Normal-Telephoto 50-500mm f/4-6.3 EX DG HSM Autofocus Lens for Nikon AF-D $999.00 http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=380688&is=USA


Does anyone know the major differences between the two other then the APO and which one is the new Model??

I like the looks of the of the 2nd one better (black instead of Gray) and I think that must be the new model correct?

The DG is the newer version, the difference being extra coating on rear element meant to reduce glare from the CCD which is more reflective than film. Whether this is a noticeable or significant improvement is open to debate.

Just got my Sigma 50-500 Bigma.....
These are just awful. The compositon is terrible. The focus is so-so. Camera shake is evident. Colors are blah. :cry:

These were all hand-held. Outside shots - it was raining. Inside shot was low light and back-lit. Thought I would give it a worst-case tryout after I took it out of the box. The good news is that I'm happy :p with the results, considering the above....... :x

It's pretty crazy that Sigma even suggests throwing on a 2X TC on it. Slow as nuts, but wow... talk about reach!

I heard the Sigma/Bigma lens tricks the camera into thinking you are still in F/5.6 so you can still AF. However, what happens when you put on a 2X TC? I mean isn't that like F/13 or something? Would you have to manually focus?

The Bigma actually does appealing sometimes, though I don't think it'd be practical for me to buy. Whatever floats your boat I guess.

You can not autofocus with a 2xTC.
