-=50D Owners Unite! Share Tips and Post Pics

Very cool moon shot.

Yeah very nice!

Just got a 50D, but I find it is soft when I used it with my siggy 30 1.4
Did I encounter with any off-focus issues?
I'll post some pics..

F2.8, focusing point on the head of the middle one

Here's one I took last year (in November!!!) at Fountains Abbey

100%

Shot handheld I assume. Could have been motion from you, @ 2.8 in daylight your shutter speed should have been high enough to compensate. Dunno. Did you have focus issues with that lens on your previous camera body? Might need to be Micro Adjusted.

Taken in the wooded area behind my house yesterday, first try at the Brenizer Method. 16 images, 50D and 85 1.8 @ 1.8.

Keep in mind, most lenses--even L glass--aren't usually razor sharp wide open. Shoot it at about f7.1 and see if it's sharp. Each lens has its own sweet spot though, f7.1 is usually a good place to start looking for the sweet spot.

Try a tilted ruler and check for consistency.

Were it a Canon lens and you could use the micro-adjustment...

First to GadgetRick, f/2.8 for this lens is not wide open. This is an f/1.4 lens.

Judson (?) -

I don't think that's a very good subject for testing focus. There doesn't seem to be much contrast at that point.

What was your shutter speed?

Also, did you do any sharpening to the photo at all?

Personally, I didn't have much luck with the focus chart or a ruler. I got better results doing what I posted here:

Hope that helps.

TRhoads I thinks it's pretty good with my t2i, I'll try micro-adjust.
GadgetRick yeah, I know this. But I assume that for this lens, @f2.8 it should perform well enough..
Jason Thanks for your advice. I've never sharpen the picture, just use the standard mode. I'll get a ruler.
Shutter speed is 1/2000 by the way

Try the setup in the link I posted above, using the box. As I mentioned, I had better luck doing that than with a ruler/yardstick alone.

Did you shoot that raw or jpeg?

Try shooting raw and do some basic sharpening in DPP - something like unsharp mask setting the sliders to 4, 4, 2 or so. This works for me for a quick sharpening. There's an anti-aliasing filter on the sensor always causes some softness.

I'm still pretty new, so I may be slightly off on that, but that's what I would try.

I shoot RAW
Ok! I've read your set up, I will definitely try your suggestion~ Thx!

You can micro adjust ANY lens on the 50D as long as the camera body recognizes lens manufacturer, maximum aperture and focal length.
