'Twas the end of a rather long day yesterday - brain went AWOL...
I was talking to a rather experienced digital photographer at work
this morning, and his thought was that the polarising filter may be
taking some 2 or 3 stops off the exposure, and allowing some camera
shake; usually, shake gives a very distinctive result with this
camera, so I don't know. I also got less sharp than usual results
at about 100 mm, so I'll have to do some experimenting. Like I
said, if anyone has any ideas or suggestions, they'd be very welcome.
G'Mornin' Keith!
Nearly every camera with TTL metering requires a circular polarizer,
in order to maintain proper exposure. If you are using an older
style, linear polarizer, that could make the two or three stops your
friend indicated... though that seems a lot, to me... I would expect
more in the 1 to 1.5 stop range.
First thought ... remove the filter and shoot some pix. See how they do.
Camera shake (if that's what it is) can be reduced by:
1) proper holding of the camera
2) firing just as your breath is finishing an exhale
3) use of a monopod. (The Gitzo G1560 Monotrek Aluminum Monopod w
Ball Head is fairly low cost, incredibly light and easy to
carry. It's what I'm using, these days for the Telyt 400 w/2x shots
and it works very well.)
Other possibilities are that your cameras AF system needs "tweaking"
by an expert or simply that your lens is in need of an overhaul. (Has
it been dropped?)
Keep us posted.
