I am very frustrated by not being able to insert a photo into the text, it apears to be a bit hit and miss: I have selected 510 pixels wide and 72 dpi, less than 100kb. Anyone any other ideas?
All shots were at the fastest aperture as this is where the lens performs poorest and where you are most likely to need quality.
Frst: Mirror lock up clamped down, IS off Manual focus after testing focus extensively, not that it was an issue.
Second: Handheld more or less the same point IS on and Auto focus Servo mode. More or less the same settings, but difference in weather realised slightly differing exposures. So I adjusted in RAW so that the optimal sharpness was visible.
Third: attach canon 1.4x Extender MLU, clamped to railing settings as before. Results are acceptable, but not what I would call publish grade quality, but not far off.
There is no conclusion, just results, this is what it does do. It suits my needs and is apparently sharper stopped down and also zoomed out (in - bloody canon!) a bit.
(All from the 5D converted from RAW, no extra sharpening -- 1452 x 480 photo)
