New to me Brit slang, Togs... I can judge by context, but more specifically, what does it mean?

Very nice, what lens did you use?

should you use noise reduction? I think I have mine turned off.

also, how do you know if a lens needs microfocus adjustment?


I'm really enjoying the camera. I don't think I'll ever pick up my xti again! Why would I? The 50D feels so good to work with I can't imagine wanting to ever use it...

I sold my XTi because the 50D performs great! Of course I had to get a T2i for backup and HD video.

>also, how do you know if a lens needs microfocus adjustment?

Start shooting and see how many images are out of focus. Then figure out if it's user error or equipment error.

pretty simple test for back/front focus

Setup with a tripod, autofocus on the pen tip, switch to liveview and zoom to 10X and see if it's off. too close then add +5MFA till you get close, too far back then -5. Then fine tune on a big screen when you get "pretty close"

doesn't look like it..... btw you need to clean your sensor.

Just curious.
Do you think air can that people use to clean their computer keyboard is acceptable form of cleaning the sensor?

WHEN AND HOW TO USE CANNED-AIR

There is a bit of hysteria about how dangerous canned air is but it has recently been disclosed that many Canon technicians depend greatly on it. If you follow these guidelines it is actually very safe:

• The preferred time to use canned air is when a bulb blower cannot dislodge a big, solid particle which can be clearly seen with the naked eye.
• Don't shake the can beforehand; there's nothing to mix.
• When spraying with it, keep it perfectly upright at 90 degrees and move the object you're blowing NOT the can.
• Always let a little air out before spraying an optic. Propellant has a tendency to build up towards the valve and will come right out if the can has been sitting for a while
• Don't let the jet-straw get any closer to the sensor than 1" or 1½" or just inside the lens mount.
• Use very short "staccato" bursts, no more than a one second shot; "freezing" will only occur when you use a prolonged stream of air.
* You will notice with canned-air that the jet-straw moves around as you pull the trigger, that's why it is strongly recommended to have the camera body on a tripod and use both hands to operate the air. IOW, hold the can in one hand and control the direction of the straw with the other; so instead of the air going helter-skelter (great song), you can pinpoint it on the sensor. This is extremely appropo for full-frame sensors where you may need to shoot a jet of air on each of the four quadrants.

Using these guidelines, we have never had any problems with canned air. If by some chance the canned air cannot remove the dastardly stuck-on specks, try ignoring them for a day or two, in many cases, they will pop off on their own. If you can determine that the speck is a dust mote and NOT a big particle of debris or grit which canned air should be able to remove, then it should be safe to proceed with a wet cleaning. If it definitely is an unmovable piece of grit that canned-air, a sensor brush or cloth cannot budge or you're not sure what to do, then, by all means, send it to the manufacturer for cleaning.
