Got my Sigma 70-300mm f4-5.6 APO DG macro the other day, so I've been taking pictures! C&C appreciated 1. 2. Taken with extension tubes 3. 4. 5. 6.
I agree, they look a bit on the soft side. What mode were you shooting in? do you have the EXIF data?
I have the same lens and please, no offense, but Im ready to throw it in the trash for its soft focus. For the life of me I cant get a sharp shot from it. Your flag shot is nice and composed well. Have fun with it and it does ok with very still subjects and is cool when using its macro feature.
Don't know the exif data, but generally, sharpest apertures are about 2-3 stopped down from widest so on a f/4 glass, optimum sharpness should be around f/8-11. Also, many Cameras by default are very soft. Change the picture control (neutral and portraits are amongst softest settings out there), boost up incamera sharpness to 4-5.
I also owned a Sigma. It was a 10-20mm wide agle, and I sold it because the images were way too soft.
#6 is my favorite. for one. its photographed properly. for two. its just looks amazing. great job! :thumbup:
The APO version isn't that bad. I have the naked one and it's a total, total mess. Though still I have a significant number of photos made with it I'm proud of. I like the last two. It all depends on one's likes.
