hmm, so im guessing a 75-200 is not good enough for wildlife shots, without excessive cropping? how much do 50-500s run for? are they inredibly expensive (>$200). and are you suggesting the tripod because it is a very long lens, or for the IS (which isnt a problem with the 5D)

There are a couple of those Sigma 170-500 APO f5-6.3lenses on Ebay right now, it looks like they may well go for less than $500 U.S. Dyxum.com reviews say that they do work on the 7d/5d though at least one of thoose Ebay sellers says they do not. I just thought I'd give a heads up, for those who may want a bargain. (cost is around 1/2 that of the 50-500, and the aperture is the same)

There's two things going for the Bigma:

1. The MTF's is slighly better @ 500mm for the 50-500mm
2. It has HSM (alas not for Minolta yet...) :evil:

FYI - f/11 and 1/80th of a second:

The 50-500 is the way to go if you can afford it. I think squirrel is in the wrong forum. He doesn't realize the 5D has AS in camera and the crop factor is 1.5.:?

HSM- Hypersonic Motor. The drive for the focus.It is faster and quieter than normal drive.

Just took delivery today of the Sigma 70-300mm APO DG Macro lens. Jeez, it's big!

The picture below is with it fully extended (using the macro switch which extends the lens about2" further than standard 300mm) and the red line is when it's fully retracted. The original 18-70mm lens is next to it.

I'm off to a football match tomorrow so am hoping to get some good zoom shots.

At last, after a month of owning the 5D, some photo's taken in direct sunlight and not overcast days. These are with the Sigma APO DG 75-300mm lens. The only post production I've done is to decrease the file size, everything else is as was taken.

Sports mode 1/1000th f7.1



Sports mode 1/500th f5.6


Sports mode 1/500th f5 (this picture was actually brightened a little on the PC!)



Sports mode 1/1000th f7.1

The above is a very good lens! You already have the 300mm range covered, so you'll have some overlap. I have the Tokina AT-X II 100-300 f/4 version of the above, and I understand it's quite similar. The constant f/4 aperature would be a boon for sports and low-light shooting.

The Sigma 50-500 "Bigma" is just plain huge! It'll get you the reach, but I wouldn't want to carry that around all day, although the 100-300 f/4's aren't that much smaller and lighter.

Good luck with your decision! :?

I have the same dilemna. I want a 70-300 Tamron, which runsĀ±$160.00. I discovered that they have a new "D" model coming out in May. It will be the same price, but I wonder if it has any real digitalenhancement or just a re-badge. Also, I wonder if it will work as well on my 800Si. Has anyone read about this lens? BTW, it's not the same one Juzzie got, it doesn't have the red ring. The Tamron part# is AF017M-700.



Update: Tamron emailed me back and said that the new lens would work better on my 5D than the older model without any difference on my film camera. I have one pre-ordered at Adorama.
