Nikon 6T vs Canon 500D @ 200mm

#1064 - You have an error in your SQL syntax;

 

I think the focus on both lenses are not the same so when the 80-200 focuses it actually focuses longer than the 80-400. For example take a prime lens (macro lens is a good example) and manually rotate the focus from closest to infinity. You should see the focal range move a few millimetres as well (as the elements move forwards and back). Some lenses (I think the micro 60mm) have a 5mm to 10mm focal change when focusing from close to infinity.

I also would like a test but at f/5.6 simply because 2.8-4 has a pretty low DOF anyway, and both lenses also offer an f/5.6. However an f/4 would be nice as well if you feel inclined to retest  

Good info!

Panos,

I like what I see with the 80-400 VR VR VR :>)))

I have heard it works great with the 24-120 VR VR VR :>))

Pardon my sillyness.

I have to get one thats all there is to it. It is sitting in the cart at B&H since this morning.

You guys are a terrible influence on my credit card. I'll send you the balance..

 

Gale - my singlet (one lens, as opposed to the doublet Canon and Nikon cu lenses) +2 and +3 B+W close up lenses work fine with my 24-120vr. And they are about half the price.

 

Panos, thanks for doing this test. Man, that 80-400vr looks nice!

 

Hi Paul, I thought about this. Each of the lenses is set to 200mm. Now when additional elements (the close-up lens) are added to the lens, it is no longer a 200mm lens. Adding positive lenses to the front of a lens, makes the lens longer. From comparison of the image sizes in Panos' work, the 80-200@200 changes to something slightly longer than the focal length the 80-400@200 becomes once new front elements are attached.

So I'm thinking the test should be conducted so the image sizes are all equal. It's the only thing that's directly measureable.
