Default Re: Thinking of selling Sigma 105-500 for Canon 100-400l...

My 100-400 was tack sharp at 100% crop @ 400mm. I still shed a little tear every time I remember that I had to sell it...

For the record, push/pull was a fantastic feature...

Thanks everyone for the feedback. I've decided I'm going to hang on to it a little longer

I had the Sigma 150-500 OS and the Canon 100-400 IS L and decided to sell one as I only had 1 body to use at the time. After a lot of testing I decided to keep the Sigma as it was the best of the 2 IMO. The IQ is very similar at the full extension, the OS/IS of the Sigma is much much better and the AF speed is very similar. I found the Sigma to be very sharp wide open and it seemed to handle failing light better than the Canon too. Maybe I got a good Sigma and a bad Canon but at f8 there was virtually no difference in quality.
I got this with a Canon 5DMkIII and Sigma 150-500 OS, taken at 1/800, ISO 1000 wide open at f6.3 @ 500mm, at a distance of around 35 feet. It's a Jpeg SOOC taken in April and just heavily cropped. No other PP at all.

From having extensively used the Sigma 150-500mm OS lens, there are no complaints from here.


Focal Length: 229.0mm
Aperture: f/7.1
Exposure Time: 0.0025 s (1/400)
ISO equiv: 100
Exposure Bias: none


Aperture: f/10.0
Exposure Time: 0.0016 s (1/640)
ISO equiv: 320
Exposure Bias: none
Metering Mode: Matrix
Exposure: program (Auto)
White Balance: Auto
Flash Fired: No (enforced)
Orientation: Normal
Color Space: sRGB

Of course, different people have different needs from equipment and a different lens may be more useful for birding than for the comparatively-larger and slower subjects shown here.

150-500 OS a LOT. I often take it out with me to shoot wild birds, as well as garden birds. I've also got a Sigma 1.4x extender.

I was wondering, would it be worth selling these, sacrificing the 100mm and buying the Canon EF 100-400mm f4.5-5.6L IS USM?

I can't speak for the 100-400, but one of the first things I did when I bought my 100/5.6 was print out a lens test chart and do some sharpness comparisons with my Sigma 150-500.
I shot with the Sigma at 500mm - of course the Sigma images were larger than those from the 400, but even when cropped and printed the same size, the shots from the 400 were significantly sharper.

all very true, one of the reasons I choose the 100-400 over the sigmas was for sports, people, events, etc. (not birds) and looking in the sports section the 100-400 pics just looked better on comparable bodies.
( Your pics not withstanding! )

Or perhaps I've fallen in the L trap myth and I can't get up
or I'm seeing stuff that's not there
