I got my Sigma 150 – 600 mm lens today. So far, just a quick glance, I am impressed! Below are listed just a few changes I am seeing that are different from the Tamron 150 – 600 mm.

The lens itself is a year newer than the Tamron.

Tamron minimum aperture is an f32 – F 40. Sigmas minimum aperture is a fixed F-22

Tamron has 20 elements, Sigma uses 24

The Tamron diameter is 95 mm, Sigma is 105 mm so the Sigma will allow more light gathering.

Tamron uses 13 groups, Sigma uses 16

Minimum focus is only 4 inches difference, Tamron being 106 inches and the Sigma is 102 inches. Not really much difference.

One of the things I noticed right away was the weight difference. This Tamron lens weighs 4.3 pounds, the Sigma lens weighs 6.31 pounds, just a shade over 2 pounds heavier. This is due to the amount of metal used in the Sigma lens. The Sigma lens is about an inch and a quarter longer and fully extended to the 600 mm position.

The Sigma is also weather sealed and the Tamron is not.

So far it looks like the Sigma is winning. The truth will be when I get to take some photos with it. Hopefully I can shoot with it tomorrow, but if not I will shoot with it Friday.

Apples to Apples, Jim, your wallet is also $1000 lighter than with a Tamron. hunf:

But yes, 150-600mm, they are...

Got tired of waiting and spent one third as much on a used Sigma 150-500 that will serve me well for a long time. Maybe I'll live long enough to buy a used 150-600...

Sonny,

Yes, you are right. My wallet is thousand dollars lighter. What I'm trying to show here is whether or not the Sigma is a better lens than the Tamron. In construction there is no doubt. I will have to wait and see as to whether the photos are any better are not.

I have become a big fan of Sigma in the last year or two. They Have made some great improvements in their glass, in some cases competing with Canon L series lenses. It will be interesting to see how well they did with this lens.

You need to remember that Sigma has made two different versions of this lens, the sport and the contemporary. The contemporary is designed to compete with Tamron. The sport version should be a better version and hopefully it is. If it is then it's worth the extra money to me. I guess I'll have to decide in the next month.

Mr. PC,

I know it is hard lens to find in the sport version right now. I lucked out, MT pointed me in the direction of where I could find a sport version in the Canon mount. He does have one on order as well as a few in the Nikon mount. I got hold of him and he told me he wasn't sure how soon he would get one of these lenses in, and was nice enough to point me to someone else. As far as the contemporary version of this lens goes I have no idea when you'll see one.

Another thing that is very hard to get a hold of is the dock to use with this lens, especially in the Canon mount. MT has these on order as well, and I will get one from him when he gets them. It was not something I am in a big rush for.

It appears Adorama got them in also. Hopefully MT gets his order in. Would much rather deal with him instead of the big dealers!

speaking of Sigma, I havent heard a single thing of the Contemporary 150-600mm..

I like both Sigma and Tamron lens. I have both and depending on the lens, I like one over the other. In this case, I think the fair comparison is the current Tamron version with the yet to be released Sigma C version. For myself, I am awaiting that release and the mass of comparisons on the two lens that will follow on all the various websites I look at before I make a purchase.

I agree and am also waiting patiently.

I spoke with B&H they told me the contemporary lens is no longer available Sigma so it was discontinued before it actually was produced.
I just received my Sigma 150 - 600 sports lens it produces fantastic pictures!

I want to know how it does at 600mm
and if it does 600 or something less like most super zooms?
