Wow, thanks a lot for Your opinions

dannyb quite interesting suggestion
My main goal for this season is taking pictures in natural light. This task ain't no easy, but I'm still learning, and here's some samples from yesterday
Polyommatus icarus 1.
icarus 2.
Icarus 3.
Icarus 4.
Icarus 5.
For this pictures I used the Tamron 90/2.8, and one blende made of a white paper
Another technique I use is combining natural light with a fill flash. Usually I use Sigma 70-300 APO attached to 3 extension tubes (for lowering the focusing distance) and Metz 48AF-1 at 1/8-1/16 flash power with a diffuser. Result is shown below
Icarus 6.
