I recently add the gem to my 70-200 f/4IS & Sigma 50f/1.4 lens collection. My 1st copy was seriously back focusing - some shots come out nice, but couldn't get sharp eyes. It showed back-focusing on test cart & my 2nd copy from B&H was good with the test chart & occasionally back focus a bit.
I have a Great copy of 70-200 f/4 IS, hit rate is very high & I rarely miss shots due to focusing issue.
Here is the question:
1. I did a shoot this weekend, I realize with a shutter speed higher than 1/200 my in-focus shot count greatly improved. Going from the 70200IS to 135L there is some learning (tele w/o IS).. But still when shooting extreme closeups - when focusing on the right eye, the left would come out sharp - back focusing a bit. Very important point to note - "At times" & not always -at around 1/400s using 5DmkI. Could it be that the AF is just fine and the shift is due to body movement either me or the model (between the time camera confirms focus & I hit the shutter release)? Will I get improved results with "AI servo" & holding the AF-ON while releasing the shutter?
[The model had very good control in holding a pose]
But, the lens is pure joy to work with the results are simply astounding - definitely an improvement over 70-200f/4IS & Sigma50f/1.4 for planned stationary portraiture (I believe I have very good copies of lens) - between the 3 - sharpness, color (sigma colors are different, but nice too) & contrast are the same. Bokeh is nice on all 3. may the FL (perspective) is about right for Portraits with very nice background blur.
2. Can the lens / coating improve the DR captured? Something nice about the lens thats hard to express.. but then I have said the same about my other lenses too.
