Tamron 150-600 Shootout via LensRentals.com
« on: January 19, 2014, 03:32:09 PM »
Roger and Aaron over at LensRentals.com have completed their resolution testing of a host of supertelephoto zoom lenses. The Sigma 50-500 OS and Canon 100-400 were the two big competitors to the new Tamron 150-600 VC.

The Tamron is the least expensive of the bunch and held up very well against others in its class. While it’s not clearly the best resolving lens. The price, focal range & performance will be a big winner for a lot of people.

Summary from LensRentals.com “My summary would be that the selection between a Tamron 150-600, Canon 100-400 IS, and Sigma 50-500 OS should be made on criteria other than MTF 50. There are some minor differences in resolution, but nothing that makes one clearly better than another. Price, weight, autofocus accuracy, effectiveness of vibration control, and a number of other factors (did I mention price?) are more important considerations when choosing among these lenses.

It’s pretty obvious that the Tamron has both 600mm range and the lowest price. These tests, and everything I see from photographers using the lens in the field, support that it’s of at least equal image quality. Some people will prefer the extra wide range of the Sigma, others the lighter weight of the Canon. But for a lot of people, the Tamron is going to be the best bang for the buck.”

"One time I dropped my camera, the shutter went off when it hit, and it made a great macro of the bottom of a dandelion.)"

Still chuckling at that after reading the review! LMAO!  Thanks for that review Roger!  We've all been waiting for you to weigh in on this lens!  Pretty impressive, especially for the price!   Still waiting for more comprehensive AF testing, although there's been a few of those already posted too.  Looking pretty impressive for the price!  If its VC and AF performance is equally impressive, this might just make a nice supplement to my 100-400L for times when I want more reach!

in short.. you get the EF 100-400mm quality from 150-400mm on the tamron ....plus an additional 200mm with not so good resolution.

now the question is how good is VC and AF with this lens.

Not so good at 600mm wide open, but it gets a lot better at f/8. Not much has been said yet about the 500mm area.

And it's cheaper too.

Certainly not prime-like IQ, but it seems a very good package all in all. Very workable flaws, to say it in other words.

Indeed.  It seems to lose ~25% of its peak resolving power (at 400mm) by the long end.  I wonder how that compares to cropping the Canon 100-400L?  Also, 600mm will have thinner DoF, meaning AF accuracy is more important.  A higher shutter speed may also be required, meaning higher ISO. 

Still, the new lens delivers surprisingly good resolution performance for the focal length and cost.

I ask the same question. The centre MTF at 400mm is 945 and 710 at 600mm, and cropping at 400 would give a similar resolution to 600mm. However, there are reports that lowering the aperture to f/8-f/11 gives a significant increase in sharpness. A pity Roger didn't measure that. We'll have to wait for SLRgear, lenstip. photozone or TDP to deliver the goods.

And that is the question I have also.  I've put off buying a friend's 100-400 Canon lens because after comparing it to the 400mm 5.6 prime, I decided I really want the lens for the reach of 400mm.  Not the flexibility of zoom.  I have my 70-200 f4 IS that does well enough for me at this point in my learning curve.  (yes, the f2.8 would be wonderful since many of my pics are low light... but the weight and cost both are a hindrance) 

My guess is that the IS of this Tamron may be enough to sway me since I'm not going to be setting up in a blind and waiting for wildlife to find me.  I'll be traipsing around and trying to find a stump/limb/trunk/rock to be my brace.  BUT, the 400mm Canon would be considerably lighter if I can get similar results from a crop.  I bit the bullet this past summer and moved up to the 5Diii on a good deal and LOVE the FF experience.  I don't want to spend money on a crop body right now, it would be better spent on good glass.

Helpful, but the two things I really wanted to know weren't answered:  How effective the VC is while panning, and how much it improves at 600mm when you stop down to f/7.1 and f/8.

Whatever that is, it triggered AVG for a web-based exploit.

I know the review was about the Tamron 150-600 but too bad Roger did not include the Sigma 150-500 instead of the 50-500.  More of a direct comparison.

This was a brilliant move by Tamron. This thing is enticing buyers who don't even have a need for it, myself included.
My photography equipment goes here, apparently.

Well this is kind of a letdown for me. I have one on order and I will see what I think of it when it comes but this comparison says its not any better than what I have at 400 and not what I want at 600. It still looks to be good for what its supposed to do but here's a flash bulletin, it's not a substitute for the 600ii, dang!

I can't tell if you were being sarcastic. Was anybody really thinking it would be a substitute for the 600 II? It's 1/12th the price. Anyway, other tests show significant sharpness gains if you stop down at 600mm, and by f/11 its just as good as at 400mm.
