Sigma 24-70mm f/2.8 HSM DG ART OS: 1300USD

 

Converter for Sony E: 250USD

Converter for Sony E: is it the MC-11?

expensive ?

Know any other 14/1.8 with AF?

 

Or meant the 24-70 (which I find suspiciously cheap)

About the 24-70mm ... I suggest to abandon all hope there ...

Probably still good for APS-C...?

The most boring standard zoom just gets 1.5 × more boring in APS-C.

 

:lol:

APS-C + speedbooster? Oh, wait...

 Let's throw an extension tube into the mix and make it a macro! 

 

  I will pay special attention to a review of this 24-70mm Art lens, what purpose in this round of Art and G2 glass has a lens which isn't sharp at the edges??

  

  Seems somewhat strange to me.......while it's up against the very decent Tamron!

Tried to post that - was not allowed - too many pictures

The Sigma is 1300$, the Nikkor 2200$

 

Does anybody think, all 900$ are just the normal overpricing of genuine lenses?  ^_^

 

For the Tamron G2 I haven't found prices or MTF
