Since I acquired this lens, I have treated this lens as my gem!
However, the biggest problem with this lens is that f4 is simply too dark for shooting macro. Especially when it comes to shooting insects...
In Australia, thanks to the ozone layer breaking down above our land and the mean, aweful drought kicking in to maintain great harsh sunlight to illuminate the environment for us. It is not unusual that insects love to stay under foliage or hide out somewhere incredibly dark.
My common strategy is to use high ISO to compensate the problem of poor lighting. But the noise is really an issue at this ISO when the shot is often taken with shutter speed of 1/8 sec or less with SR. The underexposure really makes the shot noisy.
For example,
F4 ISO 1600 1/20 sec SR
This shot is very noisy regardless what I do with PEF manipulation or photoshop work
During my trip in Taipei, I tried a new strategy:
1. I used ISO 1600, shot in PEF.
2. In Bibblepro, I use noise ninja to get rid of the noise totally 12+ strength 12+ smooth
3. In Photoshop, use Mike's find edge sharpening technique plus micro sharpening around the edges that I want to sharpen
4. Use Benjikan's "accentuation method" after the above interventions, the contrast also enhance the edge sharpness
It works as a treat
Examples
1/20s f/4.5 at 200.0mm iso1600 full exif
This shot is the one taken out of 100 or so attempts, tracking this gentleman in an abandoned construction with weeds everywhere in Taipei. The original shot is something I would discard in the trash bin on computers all the time. But Trying this method really produce "ok" images.
Few more ...
1/45s f/5.6 at 200.0mm iso800 full exif
1/500s f/5.6 at 200.0mm iso800 full exif
1/180s f/5.6 at 200.0mm iso1600 full exif
1/30s f/4.5 at 200.0mm iso800 full exif
BTW, my trip to Taiwan has been a feast - 400 clicks already 2 days into my trip
