Tamron to announce a 15-30mm f/2.8 Di VC USD G2

If it is anything like the previous version, then optical quality is very good.

That is good to new. I am not very family with Tamron lenses

Right now I am more than full with UWA lenses. Last year I added the 16-35 2.8 III to my collection and I have been very happy with it shooting inside churches and museums.

I bought the G1 version last year as a replacement for my Canon 17-40 f/4, which has a very low corner sharpness, and it was really a big leap forward. 15mm at f/2.8 combined with image stabilization is perfect for handheld night shots of still subjects. The large curved front element looks really nice. The lens is very big and heavy for a wide angle lens, but that is no minus for me, as I also love big and heavy cameras.

Using filters on that lens is quite complicated, but I do not use filters anyway. Software like Viveza allows you to achieve a look that used to be only possible with a polarizer in that past. Today you only need a polarizer if you want to get rid of reflections.

Hi Guys,

Can this lens be used on Canon EOS R?

do you think there will be any lagging / slow in auto focus?

Hope to hear your thoughts

many thanks!
