No luck with my little friend, been taking shots of the above bird and it's offspring for over a year now but today he/she was nowhere to be found. Instead had a very relaxing time hunting some local Welcome Swallows, if you want to test your reflexes it's a worthy challenge!
Looking it up it seems like it ought to mount and autofocus on a Canon body, had it been Nikon it would of been a whole other can of worms. It's an older design though (Sigma did 2 170-500mm lenses, one APO Aspherical and one APO DG...more or less same design but the DG had updated coatings on the elements) and won't have any form of optical stabilization. Will make it a handful to shoot handheld, bit lighter than my lens but at 1.3kg it's still a big lump of glass & plastic/metal to haul around and shoot. But from a tripod that's a moot point. Bit of a disclaimer, never used anything but a Sony camera so got no hands on familiarity with the D3300 and that Sigma. Time to break my gear out for a little walk here, hopefully find my favorite little subject again...Azure Kingfishers. Got this shot around a month ago and keep on going back to the same reserve with the hope that it will allow me to get this close again.
What a great guide, subbed! Unfortunately, if I have to choose between a Vive + GTX1080 combo and a 500mm lense, I thnk the gaming gear is going to win, so keep posting those pictures because I don't think I'll be taking that quality of photo for quite some time! Really enjoyed that video.
Cheers Rocky. Shot it using my Sony A77 and a Sigma 150-500mm lens from a tripod. Usually "cheat" and let the camera figure out shutter speed using spot metering on the moon rather than try and dial it in by hand. This was 500mm, 1/400sec, F/8 and ISO100...near full moon so it's rather bright. Fired off 14 shots as quick as the camera could shoot them. Processing was rather simple. First a bit of a crop in Lightroom and exported all the files as full resolution jpg's. Next step really is the key, imported the lot into Registax (free astro stacking software) and combined them all together. A single shot holds a fair bit of detail, and noise, but by combining several shots that detail is enhanced and noise removed. Saved the result and brought it back into LR for a closer crop and a few minor changes. Registax is a little tricky to use but well explained, along with download links and settings, in this tutorial starting around the 4:30 mark.
