Tamron 24-70 VC VS Sigma 35 ART. Bokeh & Sharpness.

if you have only one focal length you are limited. period.

yup.

but what does that have to do with what I said in response to a couple of people mentioning focal length changing perspective? or this conversation for that matter?

Hey guys, ...
... I just want to see how they both compare optically. If the 35 ART out does it noticeably I'd be tempted to buy it instead of the Tamron 24-70.

Any help or suggestions would be great! Thanks guys!

I happen to have both. The 35mm Art and the Tamron 24-70mm. Of course the 35 is sharper but a single spec does not make a lens. There is no way I would live without the 24-70 if I had just the 35 Art. No matter how sharp it is.

And another tip, don't read so many reviews. Or at the least take them with their due content. Talk to folks that actually have and USE them. These lenses compliment each other they do not replace each other.

Changing focal length does not change perspective

Camera position relative to subject/background is the only thing that changes perspective.

I went with the sigma 35A over upgrading my 24-105 to a f/2.8 zoom. But I did not consider the tamron due to having experience with the tamron 17-55 2.8. I liked the lens but it wasn't up to par when focusing in low light.

very happy with the sig. and have been using it and my 85 1.8 for what little event shooting I do.

I initially read it that way. But being the type to try and give the benefit of the doubt and assume good whenever possible; I came up with the, potentially grasping, explanation that, based on his framing comments, he was saying with the zoom you can get multiple perspectives of the same subject framed the same. Which is nice.
