Today I did a bad 135L test, up till now I never used 135L for a modelshoot so I wanted to test only this lens on my 5D2 with my 6yo daugher in the woods.
With a child posing it wasn't much fun, she hardly stood still, and when posing it was too static or it must be finished right away, kids have no time to lose, child photography would be nothing for me!
Setting was aperture priority at f2-f2.8 with the 580 EXII on HSS High Speed Sync at ISO 800-1000 (even this was maybe a bit low in the woods as there is less light).
I guess I better used shutterspeed priority to a fixed minimum of 1/200 ?
Suddenly I had problems with my flash, the 580 EXII eats the AA's unbelievable fast, my first pair was allready half before shooting and with my second full charged ones the pilot light didn't always charge.
Canon better used Lithium battery's and put a VISIBLE ICON that it's empty or not, now it slowly starts to work half and you have to smell it...
I also got tired that the working distance is unbelievable far, 3-5 meters with a fullframe if you want to have some background.
If you see Dankata's pics they are stunning, maybe they are all in better light at lower iso's and 5 meters away.
I also tried angles on the ground to have a blurry foreground & background but with on camera flash I needed to point it up or the foreground was too bright,
and flash half up was not so interesting as the model is 3-5 meters away to have some background, so it needs all the flashpower...
I will give the 135L some more credit and test it again, maybe in better lightning conditions and more static model the test would be better.
But it was no funday, my first idea was to sell it and only use 70-200 2.8LII IS at f2.8 next time.
