Originally posted by bass3587 I'll have to wait until the tests are complete on this lens to make a judgement of it's abilities to replace the 18-135. It would be hard to justify it in my lineup unless I gave up a couple of lens.
I have the Sigma 17-70C and the Pentax 18-135mm both of whom I'm constantly going back and forth on which one to sell so this lens would have to really spectacular for me to get rid of one of my babies
. IMO both of my lens tend to be soft at the wide and tele ends in the corners and sometimes I have to crop to get the sharpness I'm after but only sometimes.
Interesting that you complement the 18-135 with 17-70, I will be interested to see that max aperture at around 50mm, if it is at f4.5, then it will be useful for flash/night shots.

Originally posted by lesmore49 If you have a number of lenses in this approx. focal length, not much need for this lens. I have the 21mm, 18-135, 16-45. The 18-135 I bought was primarily for events and people pix. I used the 16-45 at an award event last year and I felt the high end...45mm...just didn't give me the moderate telephoto that I wished I had at this event.
The 18mm is wide enough for small, tight group shots, but the 50-135 length gives me portrait and reach out shots.
For events when I need to use flash, my go to lenses are 16-50 and 50-135. if I can get close to the action, 16-50 gets used, otherwise, 50-135 will be used (for example stage show).
