    Any Birders in Vientiane?

    Apologies for posting in the Cambodia forum - there isn't one for Laos. I'm going to be spending 12 months in Vientiane from May. Does anyone know of any birders there??

    Swarovski TLS APO 23 DSLR Adapter

    Hi Neil, You seem to be getting wonderful bokeh with this adapter on the GX8, and the video at 1440 setting showed fine feather detail, especially around the eye. What is it like to use with the GH4 for photos and video - does the absence of image stabilisation in the GH4 matter when used on a...

    Planning a short trip to the W. Pyrenees

    Hi All, I am visiting England in July and return to Oz from Paris. I'm thinking of squeezing in a short trip to the Pyrenees 16-18th July flying into Lourdes then by bus up to Luz St Sauveur or Bareges or Gavarnie. I'd like to see Lammergeier, griffon & egyptian vultures, anything else such as...

    SX40 Super Zoom

    Hi Neil Apparently the Canon SX40 can do RAW if you use the CHDK hack, there is a interesting post on Dpreview comparing hacked RAW performance of the SX30, SX40 and G12 at 1600iso and the SX40 comes out quite favourably. http://forums.dpreview.com/forums/readflat.asp?forum=1010&thread=39793941...

    digiscoping with Olympus E-PL3

    Hi Neil Thanks for trying out the SX40 (& converter) vs digiscoping options despite your gammy knee. Looks like the SX40 holds up well. I think I might have hijacked this thread somewhat, I haven't tried digiscoping despite owning a Leica Apo77, so I am a lurker on this forum. I was more...

    digiscoping with Olympus E-PL3

    Hi everyone, It would be nice to see a shootout comparison between such a 4/3 digiscoping setup at 840mm equivalent and the new Canon superzoom SX40HS also 840mm equivalent on full zoom and perhaps with a raynox converter added for extra zoom. Would the digiscoping setup come out on top in...

    advice for digiscoping with spt scope or tele

    Hi Paul, As per my newbie post yesterday on the setup thread, the problem I find with birdforum is that it is very hard to judge the quality of photos posted - pehaps this is a file size issue. It is hard not to get inspired by the results from super teles when I visit the FredMiranda's Nature...

    Astroscope + DSLR = Setups!

    Thanks everyone for your detailed responses. I will have to investigate it much further. Looking at the Lens Cell discussion, Fenando provides a good explanation of the benefits of astroscopes for light transmission vs photographic lenses with seemingly 'brighter' F stop specs. Perhaps I...

    Astroscope + DSLR = Setups!

    Hi everyone, this is my first post after long being a lurker. I recently bought a Canon 7d and have been struggling with a Sigma 400mm that only works at F5.6 on a 7d so I am looking at alternatives and am interested in the astroscope approach vs long telephoto but there is something I don't...
