...having read some info lately on the SDM it may also be of limited advantage...

I already have an old A series manual focus 50 1.4, would that still be reasonable quality given that it is on an APS-C sensor camera, and I don't mind focussing?

I know that leaves you a bit short at the longer end, with a gap between 70 and 100, but I don't suppose you'd really miss that. Depends what shots you take really, have a look through your photos and see what focal lengths you use most often.

Got a rocket blower yesterday and gave that a go but its not really for the sensor so not much good...
Hold the camera face down with the sensor exposed for cleaning, then hold the rocket blower as close to the sensor as you dare (about 1cm or so for me), and give several sharp blasts of air. I've yet to have any stubborn dirt on mine in the year I've owned it. Tempting fate I know...

Not as scientific as Martin's, these were shot handheld, so camera shake could affect sharpness with the stopped down photos. No sharpening applied to any of these pylon shots.
So here's the over all shot:

This 100% crop at f/4:

f/4.5:

f/5.6:

See any real difference between them?
Here's a shot straight into the setting sun. Any flare?

And a grab shot of a passing plane, f/4.5, 100% crop, no sharpening.

As luck would have it, we saw a passing Barn Owl, right across the other side of the field we were in. On the shady side of the hedge. f/5.6, 1/45s, ISO400, 100% crop. Nice to see though, first one in our local park since 2003 (that we've seen). Flew right off with that meal, so must be feeding young.

Peter, you're going to love this lens!

I suppose you might get lucky with some older stock somewhere. I did have a spare licence, but I gave it to another forum member.

Nice shot, but yes, it does look a little odd with nothing in the background.
