Why 'stop' @2.8. That's not fair '2' those more 'open-minded' or those who have had 1.2 many cocktails.Careful with those, corner sharpness will deteriorate, and you can expect increased vignetting
Thanks for all the great advice. That e-book might be very useful.As far as I know, changing the focusing screen is recommended for wide aperture lenses (f < 2.8 ), so I don't think it will help with the TS-E 24mm.
I was checking focussing screens .
Am I correct there are no Canon focusing screens for the 5D Mark III.
Is it even necessary / helpful?
Some great advice there everyone. Very informative and food for thought.As far as I know, changing the focusing screen is recommended for wide aperture lenses (f < 2.8 ), so I don't think it will help with the TS-E 24mm
Someone recommended changing the focusing screen.
Is that a good way to go as well.
Kind Regards

Please note that when you are looking at live view, you are looking at F2.8. It will be tough to get all portions of the scene super sharp at 2.8, even with tilt. If you press your depth-of-field preview button to stop down the lens to your preferred aperture setting, you'll then see what the image will look like at that aperture. If you are set to F16-F22, I'll bet everything will be sharp.not 2.8, it is f/3.5 - that is the max aperture for the TS-E 24mm. But what you said still applies, of course
Consider the Sirui K range of ballheads, build quality similar to BH-55 at half the price.Really? I do have a Sirui K 30x and M-3004 legs (and like it), but have yet to get my hands on a RRS.
I enjoy telephoto compression in landscape as well. I would also like to try a T/S lens. I didn't realize the 17-40 Canon needed to be closed to f/11 to be sharp in the corners. That's too much like what I have had to do with crop lenses...so maybe I should forget about ever buying a 17-40. The Tokina 16-28 seems like it will be great, but it only goes to 28...You mean you like the telephoto FOV? :-)
+1, I also use the 15-85 and 70-300LEF-S 17-55 f2.8 IS
or
EF-S 15-85 IS (dont confuse this with the not so good 17-85)
the first gives much wider aperture availability and constant f2.8 which is very nice
the later is variable aperture and much slower but gives a wider wide end and much greater zoom range
they are similar prices
depending on which strengths you prefer either will be excellent
if you shoot alot of low light i would go with the first option if not so much and the greater zoom range is appealing go with the second
Agreed. Both will give you significantly better quality. If you are in the U.S. the EF-S 15-85 is much cheaper. It is on my 7D about 80% of the time. If traveling, I take only this lens and my 70-300 "L" and can cover just about anything.
Others may disagree, but in my opinion, in the wide range, there aren't practical EF alternatives. (Both of these lenses are good enough that if you later move to full-frame they should have decent resell value. )
