Calling out to any Sigma 300-800 Wildlife photographers out there.... | |

Lil here is what I think. The wildlife photographers always finds their lenses are not long enough for their subjects. I think it is a fact. When you are considering a lens the following important points also must not be ignored.
The sharpness of the lens If your lens is sharp enough and if you could obtain a 100% proper focus you could obtain a very sharp crop image. If the crop image ends up with 4-6 MPs after a tight crop from a 10MP sensor, the final results would be as good as from an un-crop image.
Focusing speed Very important for BIF images as well as other subjects.
Low light capabilities a minimum of F4 aperture is a great plus. Also if you have IS or VR you will have more opportunity to capture more subjects in slower shutter speeds in difficult lighting situations. Dont forget most of the birds and animals could be spotted during early or late hours of a day.
Size and the weight You must be able to carry your gear easily. Especially when you are spotting something you cannot always use a tripod. I always take my tripod, monopod and car-window mount in my vehicle but never use any of them.
Sigma 300-800is not a very sharp lens according to most of the reviews. But I have seen some very good photograph of Sigma 300-800. Maybe if you are a very capable photographer and if you have high PP skills this lens may work for you. Try to get hold of a lens for rent before making a decision.

Hi Jude,
this is a very thought through reply & I thank you for your time & effort. You're so right - - nothing is long enough (for me) as far back as I can remember all I've wanted is long lenses. Could not care less for wide angles. 
Sharpness - - you're right. Has to be sharp.
Focus speed - - well, I'm slow to focus so I don't worry about the lens being slow. 
Low Light - - knowing myself as I do, this is not really an issue. I know it sounds strange, but believe me - - it's true. 
Size & weight - - yes, this has been something I've been thinking about. But even when my husband read & calculated the weight with camera/tripod/Wimberley Gimbal my husband didn't even react. He knows how strong I am.
I almost always work off a tripod. I can handhold, but prefer tripod work. I have a monopod - - never used it - - yet. 
Jude I did get to shoot with it Saturday for a while. I held the lens, granted not attached to the camera nor tripod.... But I did shoot with it. I don't expect miracles, but..... Also, I've read a lot of positive reviews of this lens. I must have visited the wrong reviews......
I'll do some more research.... Thanks for input.
Lil
