Hi all

I found a very interesting blog post regarding autofocus (AFMA) and lightning conditions:
Here one picture which shows the autofocus result with a Canon EF 85mm f/1.2L

Also, it's just a few results and not yet a full range of many tests. But still, it shows a big variance depending on the used lightning when using autofocus, or doing AFMA.

What do you think of this?

Lenses / A used 100-400 f/4.5-5.6 L IS USM worth to buy for ~750 USD

Hi All
I might have an offer to buy a used Canon 100-400 f/4.5-5.6 L IS USM for around 750 USD. I don't yet have any usefull lens in that range, only the Sigma 400mm F5.6 APO Marco HSM which is not rechipped (and thus only with open aperture).
The lens has a little dust inside and the hood mounting mechanism is broken, but the seller says it's optically in otherwise perfect condition.

What do you think? Shall I rather way for the successor of this lens or get it? I'm not really in a hurry to buy it, but I think it's a really nice offer.

Underwater / Cheap underwater flash

Hi All
I own a Canon Ixus 960 IS with the fitting case WP-DC19. I search now for an inexpensive flash which I could use. One I saw is the Ikelite AF35 which might be useable.
It has to survive diving depths of 40 meters, should use rechargeable batteries and, most important, should work as a Slave which gets triggered by the built in flash.
Any recommendations?

Hello All
I am currently evaluating if I should upgrade my EOS 550D with a really nice 6D. The main reasons for this are:
- bigger body, but still not as big as the 550D with the battery kit mounted, thus it's better in hand
- bigger viewfinder
- MUCH better low light performance (probably the main reason)
- full frame sensor (a little bit more detail)
The main use of the camera is everyday pictures. I always carry my 550D with a Sigma 18-125 lens with me around and I like the range of this lens. I picture mostly animals, landscapes and buildings, but normally no people.
I compared the two lenses over at Dxomark, here the compare with the 5D MK2: http://www.dxomark.com/index.php/Lenses/Compare-Camera-Lenses/Compare-lenses/(lens1)/211/(brand)/Tamron/(camera1)/483/(lens2)/164/(brand2)/Canon/(camera2)/483
The canon is a bit sharper, but with "only" 1/3 of reach. I don't think I'll feel the difference of 24mm to 28mm at all with my shooting habits.
What do you think, should I take the better and sharper Canon lens, but loose quite a bit reach, or is the difference in sharpness anyway not visible if I'm not going to pixel peep?
