So I was wondering: let's say Canon announces a 17-40 f/4 L IS instead of the 14-24 f/2.8
How many of you will be happier (not just happy for Canon or happy in general for humankind- I mean will seriously plan to buy it)?
Nikon did it- can't be out of the question, and will probably cost similar to the 16-35 II
Would you prefer a 17-40 f/4 IS or a 14-24 f/2.8?
IS is welcome, but what I would really like is a 17-40L ii that is tack sharp on the corners with little distortion. Currently, if I take group shots and have people at the ends, the lens makes a 170lb man look like 340lb... I am still looking for the person that appreciates those kinds of "embellishments".
You are not talking about lens distortion, you are talking about anamorphic projection distortion. That is easily corrected in post if you need to.
In PhotoShop you need to open an 8bit file as the distort filter doesn't work in 16bits up to at least the end of CS5 (not sure about CS6).
Open your file,
1. go - filter > distort > spherize, set to 25%, make sure the option box is set to
horizontal only, click OK
2. then - select > all
3. then edit > free transform, set W (width) to 91% and apply changes.
These figures work well for my 16-35 at 16, but you will need to mess about a little to find figures that work for your lenses. But follow this recipe and you 340lb guy will revert to close 170lb.
