Zoom for wildlife

I have the 100-400 and the 150-500 (pre OS, but my Pentax has in body OS). In very good light the 150-500 will give the 100-400 a good run for it's money, but it only really comes to life at F9 or F10. The Canon will work in less light.

Another minor point, although the Sigma is heavier than the Canon, it is easier to manage as the tripod mount doubles as a substantial carrying handle.

OTHER LENS MANUFACTURERS PLEASE TAKE NOTE.

would be nice to see some pics taken at 400mm of same subject roger if you have the time.

Hi Scott.

It would be slightly disingenuous to do a comparison as the 150-500 goes on me Pentax and the 100-400 does not.

Blisteringly good pics by the way. :thumbs:
 
Interesting.
With more and more megaPixel bodies, I would prefer better IQ and less reach. The xtra MP would allow me to crop a better image.
I have yet to take a sharp enough image with a Sigma

i would rather have reach than mp, so your sayin you would rather have a 7d and 100-400mm than a d3s and a 600 f4, or a 1dmk4 and a 500f4:thinking:

And you're saying that you believe the 100-400 has better IQ than either the 500 or 600 f4s. Because that's certainly what you ascertation implies.

frank deon said he would rather have more mega pixels for cropping than reach so ie a 7d with a 100-400mm on rather than a low mp camera d3s with a 600mm f4 on, i know which set up i would rather have and its not the one with more mps.

Oh, come on! I even highlighted the bit you're ignoring. He said "I would prefer better IQ and less reach"

See - better IQ and less reach. Do I need to repeat it again?

ie a 7d with a 100-400mm on rather than a low mp camera d3s with a 600mm f4 on

ie NOT a 7d with a 100-400mm compared to a d3s with a 600 f4. Because the 100-400 is not better IQ and less reach.


To give a proper comparison, which would you prefer; a 7D with a 100-400mm or a 3ds with a 500mm mirror lens?

read it as you want frank, i have read it they way i want to, im not gonna argue with you over it, i will carry on using my naff 50-500mm os and you use what ever you use.
as far as im concerned the 100-400mm is a good lens but its no better than the sigmas and certainly not worth the extra over the 150-500mm same with the 50-500mm but thats just life.

so what is a 100-400mm if it has not got better image quality and less reach.:thinking:

And I thought osmium was dense. It has got less reach than a 600 f4; it has not got better IQ than a 600f4 - despite your beliefs.
your real bright frank and i think your very rude,
600mm f4 on a d3s(full frame is 600mm 35mm terms)
a 100-400mm and a 7d(1.6x crop) is what frank try 640mm in 35mm

How on Gods earth do you arrive at that?

Oh dear! :nono:

"because" is a conjunction which is a word used to join two words or phrases. I cannot be used to start a sentence in the context in which you have used it (although "Because the train left early, they missed it" would be acceptable).

That which is asserted is an assertion.

If it is asserted, it is not implied.

Dives for cover. :wave:
