Looks pretty professional to me. But I gotta be careful pointing that thing in public. Just might be arrested for suspected arms possession. Thanks Ombre for sharing information on your DIY lens hood. I'll head in the same direction, and do some DIY too.
That's some huge lens. Is that termed as a super telephoto?
By the way Omre, with the tube at 15cm, will it increase vignetting? The minimum focal length of a tcon-17 without vignetting for a FZ30 for example is approximately 180mm; with an added tubular hood at 15cm, the minimum focal length without vignetting should increase. My apologies, just a question out of curiousity. Contrary to the question, I understand that the tele-end should be of upmost importance, not the minimum focal length mentioned.
Further, why 15cm?
Sorry for all these questions... heeheehee...
Thanks Omre!
