Sigma 150-600mm REALLY 600mm??
Dec 10, 2014 16:41:23 #
OK, so I just did this with the Canon mount Tamron and it was asked if I could also do the same with a 150-600mm Sigma. Why not?
I decided to use the Nikon mounts this time, same setup, same tripod that I had not yet taken down from the Tamron comparison. I did use the Nikon D750 body, Sigma 150-600mm Sports model, and Nikon 600mm F4 VR II model lenses. ISO was set at 1600 again but with the Nikon I had to up the aperture to F10 in order to shoot at its max shutter speed of 1/4000 sec under the same conditions.
I didn't notice until after downloading the pics that I had the Sigma slightly off level, again this is not a "scientific" test I am doing here.
The magnification of the two lenses seems to again be quite comparable, so you are getting a full 600mm of lens with the Sigma as well.
The sigma does have a very slight falloff of resolution, but its quite minimal and is very comparable to the Nikon at the deep crop samples. Noise is minimal and acceptable even in the dark shade, and details are quite good at the distance. CA is quite minimal in both lenses.
I have intentionally selected a crop target in all these comparisons that is in the shade on a sunny day as this is typically a very tough subject to resolve. Comparisons in the bright sunlight would likely have a similar result though.

Maybe it's my eyes MT but the Nikon seems to have better edge sharpness with the pipe in the second set.

It does. Like I said above, the Sigma loses a little resolution when really cropped in. And that "pipe" as you call it is just the hinge on the storm door, its 3/8" diameter and 2 1/2" tall.

I'd agree, but for the price difference I could easily live with it...

hmm...this is actually making me re-think getting (or ordering) the Sigma 150-600 sport. Your Tamron comparison looked better in comparison to the 600mm Canon.

MT Shooter: by the way, how does the sigma deal with the "breathing"?
does it breath a lot?

Hardly at all. Here is a shot taken at 600mm, manually focused, then zoomed out to 150mm for the second shot, no focusing compensation was done at all, same setting.

Focus breathing: the term used to describe the (unwanted) small change of focal length (and hence angle of view and magnification) when the focus distance of a lens is changed.
Is this an accurate description to include in the FAQ: Common Photographic Terms & Abbreviations at http://www.uglyhedgehog.com/t-26493-1.html ?
Is there another type of lens "breathing"?

Are assured that the Nikon or Canon 600mm are really 600mm for standard comparison?
I think that the internal focusing system of lenses making these differences

Has your comparison effort diminished your enthusiasm for the Sigma or raised your opinion of the Tamron? Would appreciate your thoughts comparing the two. I ask as my wife wants to give me one of these as a Christmas gift.

MT: I have the D7000 and which lens (150-600mm) would you go with between the Tamron and Sigma?
Thanks.
Thanks.

Have you done a Sigma 150-600mm and Tamron 150-600mm Test shoot??? I would expect a $1,300.00 worth of difference in performance.

MT, How good you grade the Sigma's corners vs the Tamron?
I remember the Sigma executives were boasting about the sport's better corners.

Breathing? Hah!! I brought this subject up about the Nikon 70-200mm VRII which was mentioned by Thom Hogan in his review of the lens and got skewered. So....is there actually somebody out there who believes this is important?
