Sigma 150-500mm Vs Canon 100-400L

Sorry to be blunt, but that is garbage. I don't see folks shying away from the 500 or 600mm lenses that were released only one year later. If it isn't broken, there is little to no reason to spend R&D dollars to fix.

sorry but I simply don't want to buy something that old, I don't care if its still in production, its still old. Plus I really dislike the pump zooming from early 90s.

i might buy Sigma 50-500

both Sigma 150-500 and 100-400L are not wide enough, if I bought 150-500 then I would have to keep changing lenses all the time when I go out. and 100-400L if i wanted the same reach as 500 then I would have to use the 1.4 extender, and then if i wanted to shoot more wide then remove extenter. to much change over.

from the reviews I seen the 50-500 is sharper then 150-500.

If you can swing it, the 50-500 OS is a nice lens. I just could not afford it.

The upshot is that I sold my trusty 100-400 after trying the Canon 300mm F4 L IS. At anything over 300mm this lens is a significant notch above the lenses you are considering, note this is without T/Cs. I find that on my 300 a 50% (area) crop will give good A3 prints, as good if not better than my 100-400 did with less (25%) cropping and it was at 400mm! So I lost 100mm but still got better frame fillers.
Basically the 300 is a sharper (much), higher resolution lens with better colour/contrast and it's smaller, a little lighter and a little cheaper. It's an old design and is not perfect but, in my experience, a significantly better wildlife lens than the ones you are looking at. Try one, compare the images, then become the proud owner of one. I did!

Thanks, I'm glad to hear that. I've been spinning my head in circles trying to figure out budget 400 or 500mm lenses and everything else I've seen has just compared 300 f/4 with 1.4 TC to the 400 f/5.6L and the 100-400L. You make a good point that with resolution to spare, you can just use it at 300 f/4 without the TC and crop to 400mm equivalent. I may just try this, since I have other uses I could find for a 300 f/4, but a 400 f/5.6 is going to be a bird lens only

I have played with both but HIGHLY prefer the 100-400mm.

Its sharper, faster, more colorful and contrasty and just feels better.

Well, I didn't say anyone said it's a bad lens.

But you implied it by saying you disagree and that it can produce decent results, which tells me that you thought people were saying it couldn't produce decent results and ergo, was a bad lens.

That said, when not pixel peeping, there won't be too much of a difference, but I can still see better sharpness from the 100-400.

FFS this is like buying cars, set a budget, try both and pick your poison

That reasoning just sounds ignorant to me.

Here is a back to back review I did a couple of years ago between these lenses. It was interesting, to me anyways!

Thanks! Like other tests there wasn't a whole lot of difference in IQ, that is until you added the TCs. At that point it was no contest.

Concur, it is ignorant. I suppose he wouldn't take a 500/4 because it is nearly as old as well. I'm willing to bet you've never used the pump action or you'd realize it is the perfect solution to fast zooming for wildlife.

The sigma 150-500 is a VERY capable lens, one just needs to know how to use a long lens properly. These are all hand held under 1/320th, most 1/250th @ 500mm.

not really, just like cars, If there is a car A that was in production for 12 years still build with older tech closer to its end of life cycle, and car B that was build for 2 years just starting its life cycle. I would pick car B.

But there is one difference. 12year old cars are no more manufactured, while 500/4L and 100-400 etc still are in production!
So you barely cant get "new" 12yr old car, but you can go to a shop and get brand new 100-400L. Which is now, after being used so many years, known to be very good tele zoom lens.
