    Nikon D7000 and Sigma 300mm f2.8

    Sorry to hear that!

    Vortex Talon HD 32mm class? Yes!

    Frank, Thank you, I will look at your comparison, and message you about it then. I agree with what you have said, although the lens glass types and quality, lens coatings, and their entire design and layout probably have some effect on brightness...and certainly on contrast. What is...

    Nikon D7000 and Sigma 300mm f2.8

    I look forward to seeing them. Yes I could tell by the fine grain that you hadn't used much NR in Photoshop. Do you mostly perform NR in Adobe Camera Raw, or do you do it in the full Photoshop, after converting to a TIFF file or whatever? I really prefer Camera Raw, even though the full...

    Vortex Talon HD 32mm class? Yes!

    Frank, That's very interesting to me, that you have tried both. Did you not find that the Vixen was brighter than the Sightron? I'd be interested in discussing it further, if you'd like to private message me sometime. I wish I had the disposable income to just keep buying and try everything...

    A D800 at last

    You guys seem to be illustrating my point...that with the D800, Nikon certainly has a fine camera, but their lens lineup seems not quite as nice as Canon's. In my opinion, a crop camera will be better for bird photography anyway, making more use of a telephoto len's detail. A 7D or D7000 and a...

    Vortex Talon HD 32mm class? Yes!

    The latest on these Talon HD's, as far as I know, is that they were supposed to come out the end of March, and yet they still haven't. This was told to me via email by a Vortex representative. I've already spent beyond my limit on binoculars for the year, so it will be fun to watch all the...

    Nikon D7000 and Sigma 300mm f2.8

    Interesting, I had no idea the D7000 could AF at aperture smaller than f/5.6 (most Canon bodies won't, as you probably know). So yes, I'll concede that one advantage to your D7000 for sure. That picture has nice focus, although that particular bird isn't very pretty to me, to look at. I...

    A D800 at last

    Neil, that's a nice looking Kowa lens/scope. I somehow had a feeling your images weren't shot via a scope with the prism still in the chain. Those are some great shots, you should try to sell prints. I like the idea of Nikon's 1.7x teleconverter, rather than the 2x...it's a shame Canon never...

    What's your favorite porro today?

    I apologize for not addressing more of you sooner, and will try to over the next week. All of your information is extremely valuable! I've decided against buying a new porro prism at this time, but I still want one in the next year or so. Other sale items kind of changed my mind. FrankD, I...

    So those images are through a scope? Great results!

    Nikon D7000 and Sigma 300mm f2.8

    The Black Fox, I like some of your bird shots. I agree on the lack of affordable Nikon lenses. The latest versions of many of Canon's super-telephotos, however, are even less reasonably priced than Nikon's have been. If I had to buy any Nikon lens right now, within a reasonable price range...

    Vanguard Endeavor ED 10x42

    John, I have tried to shed light on the performance of Vanguard optics, and even purchased some myself. I hope those who read this, who actually spend their hard earned money, will find MY comments of value. Your binoculars I believe were a gift to you (and yet you are collecting the rebate...

    Nikon D7000 and Sigma 300mm f2.8

    Kenneth, that's very interesting. Apbarr, I apologize for the thread no longer focusing on your original post, or on Nikon in general. Is it really that much of a bother to you, though? I'm learning new things here, and I didn't realize we had to adhere to your wishes, per se. However, I do...

    Vanguard Endeavor ED 10x42

    John, try this: During mid afternoon, when there is a bright sky, go out and "glass" at a small tree limb set against the brighter sky (preferably at a distance of 50 feet or closer to you). Make sure the tree limb is oriented more vertically, rather than horizontally, in your field of view...

    Nikon D7000 and Sigma 300mm f2.8

    Kenneth, my understanding was that none of the FD mount lenses ever had autofocus, so how could it use the electrical contacts to confirm AF? It looks like you're saying they did have autofocus. Perhaps I read something wrong at wikipedia? I still wonder which of the FD lenses is worth...
