This past weekend my wife was performing in an indoor choir performance at church - Great I figure an excuse to take pictures - indeed a perfect venue for using my fastest lens - the Canon 50mm f1.8 II.
While waiting for the show to start I was taking test shots to see what speed/aperature settings were possible in the available light - and I noticed that the closer to f1.8 I got the softer the pictures got, now admittedly I was making this determination by looking at the not so hi-res 2.5" LCD on my Rebel XS, but when the aperture was set to f4 everything was as sharp as a tack, when set to f1.8 everything was blurred...I really looked at the entire picture to make sure that it wasn't a Depth of Field thing. I tried manually focusing until a particular focus dot blinked, snapped a picture and then looked at the face that had been focused on - f1.8 blur, f4 sharp.
I'm going to set up some sort of more tightly controlled test this weekend. Set the camera on a tripod, use a camera release etc and take a series of shots to check if what I was seeing is actually related to the lens or not.
Has anyone used Canon's little f1.8 50mm enough to say - yes indeed "that's just the way it goes with a $100 lens you silly man", or maybe this particular lens needs some help?
