Sigma APO 50-500 Vs APO 100-400 SO

Thu Aug 12, 2004 6:51 am

Hello,

I have a Sigma 50-500 and not yet used as I want; few shots and only 10/15% acceptable (most of my shots are too soft).

I sent the camera to Canon (10D) to be checked and it is ok.

So now my question is: would I try to buy a new Sigma100-400 SO, or in case of airplane shots the SO/IS systems are not necessary?

The lens itself is good, because sometimes I have a very sharp images, so I believe that the problem cold be solved by SO/IS system.

Please let me have Your advises.

Regards

Max!

you might be using your lens as if it was mounted on a analog camera.
Don't forget when shooting at 500mm it will be 800mm when mounted on your 10D which of course affects the exposure time you can use.
You might try a one-leg or a tripod.

Thanks for answering.

Do You think that a monopod will help me in having sharpen pictures, even if I usually shoot with panning?

Thanks

Max!

Max, are you referring to the Sigma 80-400 OS?

The only other lens in that size range would be the 135-400mm f/4.5-5.6 but it doesn't offer OS.

It will help for sure but panning with 800mm mounted on your camera will take some practice to get it right.
If you are not using a monopod try to shoot faster then 1/800 of a second(at 800mm that is) or try 1/1000s and see if that helps.
Of course you need enough light and/or going back to ISO 200.... 400
At least it will tell you where the problem is, you or the lens.

Best of luck,
Willem

Hi Max
The 50-500 is not something you can throw on a 10D and have immediate success with.
It takes a fair bit of practice to get you technique down and your success rate up.
You really need to practice to see great results.
As a test of sharpness put it on a tripod and check the results which will probably be very sharp.
Technique is everything.

Hi Max,

I've been using the Sigma EX80-400 and with some good results:

It is a good option over the 50-500 due to the OS.

Best regards
