Canon TS-E 24mm f/3.5L

Review Date: Mar 3, 2006 Recommend? yes | Price paid: Not Indicated | Rating: 10 

 
Pros: Tilting and Shifting. Of course. The tilting is very impression. Auto diaphragm works. Focus points will beep when focused on my 20D.
Cons:
Tilting seems to be over-exposed 1EV. Soft at F/3.5, but F/4 seems to be quite useable (not sharp though).

If you are looking for a sharp prime, this lens might not be what you want. But if you need tilting and shitfting, there is not other choice out there.

Handheld is quite manageable, but I cannot see the effect of tilt thoguht just my 20D small viewfinder. When using tripod and "angular viewfinder", you can really see the effect of tilting.

You can change the shift and tilt axes to the parallel position by yourself when needed. No need to send it in Canon service center. You can easily find the information by google.

Pros: Constrast and color, especially in low light. F/2.8 usable, F/4 tack sharp.
Cons:
Size/weight but managable when you get used to it. Big Hood.

Why not 24mm-105mm IS:
I shoot a lot of interior/architecture in lower light condition. I decided not to get 24-105mm IS, due to its more obvious distortion on both ends.

F/2.8, F/4 and DOF:
This lens is also used as a general PORTRAIT lens. Nice OOF background blur. I tested some shots with F/2.8 and F/4 to see the difference of OOF. Honestly, not dramatically different especially on 1.6Crop body. But still "recognizably" different.

When I say the F/2.8 is usable, means the sharpness is acceptable, especailly we need to consider the shallow DOF would easily make the image not that sharp. When I took shots of something with higher color/texture contrast, the result of F/2.8 is quite nice (not amazing, but quite pleasing).

I used 24mm f/1.4 before. I feel like on all faster lenses: The sharpness issue in wide open is considerably improvable with good management of DOF and choice of objects. (I am talking about fast lenses with shorter focal length. Not the DOF thing on the amazing 70-200mm)

Happy Shooting~
