Sigma 50-500mm F4-6.3 EX DG HSM

[robbie_robertson]

Before I lay out cash for this Sigma lense, can anyone provide (please, only

from specific experience with this lense) input? I do a lot of wildlife

photography from my back deck. Currently using The Nikkor VR 70-300mm with a

Tamron 2X teleconverter on my D40X, and that setup is proving itself to be a

poor man's very cumbersome long lense, e.g. Autofocus doesn't work reliably

because the minimum aperture exceeds F4. Oh well, chalk it up to being cheap

and ignorant.

I hear some negatives about the Sigma lense: Autofocus being slow in

extreme zoom, and photos having a soft look at that range too, fragile, and

lousy customer service in the event it's needed. Your knowledgeable input

would be appriecated.

Thx,

RR

I also did a few quick test shots:

Whoops! Looks like it was already a well-hashed subject. Thanks Shun.

Robbie, perhaps 90% of the subjects here have already been discussed at least a few times, so it is not a big deal.

 

I seem to recall that this very topic has been discussed at least 3 to 5 times in the last year or two, but you need to do some searching yourself. Unfortunately, photo.net's search capability can, let's put it this way, use a lot of improvement.

Or try to find a used 1000mm f11 Reflex-Nikkor lens. It has (probably) better glass than the Sigma zoon, and with a decent tripod, the lens works.<div></div>
