Arty said:Optics will need to be fine and the AF needs to be fast and accurate before I would be interested. The 45 looks interesting, but only if the VC is fast. I am in no hurry to buy more lenses, but I sure would like to see a Canon 50 F2 IS with performance like the 35F2 IS.andrewflo said:ajfotofilmagem said:I imagine a similar price with the Canon 35mm F2 IS.siegsAR said:I wonder how their 35 perform against Canon's 35 f/2 with IS?

If the Tamron has 80% of the image quality, and cost less than the Canon, can be advantageous because the aperture F1.8
Good speculation. I did try the SP 15-30mm for a few weeks before exchanging it for a 16-35mm f/4L and I have to say the image quality was unbelievable. Without pixel peeping at 400% at brick walls, it felt like the Tamron outperformed the Canon, even at f/2.8. The build quality was better too. I traded it in purely for portability and filter threads.
This is of course saying a lot considering the Canon f/4 is stunning. Basically I wouldn't count Tamron out against the 35mm f/2 IS just yet
Tamron seriously stepped up their SP line with the 15-30mm. It's WAAY better than the SP 24-70 or SP 70-200, which were already great lenses as it stood.
I'll be patiently waiting to see if they can up the ante again with these new primes A 45mm f/1.8 VC sounds terrific IMO.
Did you mean "as long as the AF is fast" instead of "VC"? Would have to agree if so. The SP 15-30 had really fast, silent, and accurate AF but on an UWA it's a different ball game than 45mm.
Btw the VC on the 15-30 is way quieter than the IS on the Canon 16-35 f/4.
I've never used the Canon 24-70 II or Tamron SP 70-200... but I do have the SP 24-70 and Canon 70-200 II and the Canon is noticeably faster.
The SP 24-70 is ever so slightly slow in use, especially on a 6D where I almost always use center-point-recompose if I want confidence that the AF is locked in properly (sacrifice critical focus by recomposing has proved more reliable than trusting the 6D's outer focus points for me unfortunately).
But it's by no means a deal breaker! Tamron SP lenses really are 95% of Canon L-series, but at bargain prices.
