    Digiscoping vs. DSLR Test

    Paul, I have given up on this tread and this is my last post in it. I have no interest in discussions where people and don't show respect for others - this is just not my cup of tea. You can read my opinion about this topic, if this is of any interest to you, in my answer to your previous...

    Kevin, Unfortunately, like Paul Hackett said, it seems we have a stalemate, so I think we might as well stop the discussion here. I assure you I did not want to trick you, get one over on you and I don't think you vere talking rubbish. Reading your last post, you were obviously under that...

    Norm, thanks for your positive contribution to this thread. It is much appreciated.

    Paul, Thank you for your interesting comments. I appreciate your sensible input. English is not my mother tongue so maybe I have not made myself clear. I will try once more. My opinion is that DSLR is better at close range and that digiscoping is better at long range. I don't think anybody...

    Thanks for the suggestions Kevin. I believe that the 823 has been discontinued. I don't know what I'll do. I bought this scope for my wife who is not into photography and it is perfectly adequate for her. This scope in a pretty good performer for the price. However, I understand it is not...

    Kevin, it just doesn't work. In your post of yesterday, when you first show the photographs, there is 1 pic with the 20D and 2 with the A95. Here are the dimensions of the pics: 20D 500+ 1.4TC: 636x544 A95 zoom at 3.5: 588x524 A95 zoom at 2.8: 800x659 Today you post 2 pics and one of those is...

    Kevin, I could be wrong, but I think that we doing it and you doing it before posting is not the same. Since your DSLR has less reach, you have to enlarge it using the Zoom Slider in PS until the Coke bottle is the same width as the other pic. Then you crop each picture at the same dimensions...

    Kevin, thanks for your comments about my Web site. You will surely be interested to know that the Grebes eating bullfrogs pictures are about 100% crops.... It was very early in the morning and the light was horrible and yellowish - also I had forgotten my flash. This was probably at the...

    Digiscoping vs. DSLR Test

    Kevin, I was writing my last post when you uploaded yours. Sorry I have not read it before posting. IMO, the DSLR picture you submit cannot be compared to the digiscoped one since they are not the same size. This is unfortunately the problem with those tests that are anything but valid...

    Digiscoping vs. DSLR Test

    Humm... Kevin, you are making me say things I haven't said. 1. "The thing that you are confusing is the distance a photograh is taken at". I don't think I am confusing anything and I fully understand your claim. My opinion is that at 20 meters in the conditions of your example, the DSLR...

    Digiscoping vs. DSLR Test

    Kevin, I figured 32X for the digiscoping setup because you wrote that there was no zoom on the A95: "Two photographs taken, one with no zoom on camera (f2.8, other camera zoomed as far as f3.5." I just don't believe that, at 20 meters, a good quality 32X 5mpx digiscoping setup should give more...

    Will, I agree with you that "seriously" out of focus may be pushing it a little. However, I don't think cropping should introduce focusing problems like we see in Kevin's DSLR cropped picture unless there is already a focus problem. Of course, cropping introduces problems because one has to...

    Kevin, not a very good example since your DSLR photo is seriously out of focus.

    Digiscoping vs. DSLR Test

    Neil, I have tried the A640 with every possible combinaison of zoom and distance from the eyepiece and I cannot get rid of vignetting. So this option is out. I think I will try the P5000 again - it is slow but I think I can live with that and I like everything else about it. Thanks a lot for...

    Digiscoping vs. DSLR Test

    Ok, the blurring explains the difference in the backgrounds but again, to my eye, both birds are as good. There are differences of course but they could be caused by focus and depth of field. One thing is sure, your mate has done a fantastic processing job. Bear in mind that my comments...

    Thanks for the info. This is an interesting quiz. I took the liberty to copy your photographs but the copies were destroyed afterwards. I enlarged them 300% in PS. The noise and cropping/enlarging artefacts ON the bird seems similar, the noise and cropping/enlarging artefacts AROUND the bird...

    Hey ! This is not fair... You have to tell us more about each setup. For example, you won't get the same results at 500mm with a Sigma 170-500 or a Canon 500 prime.

    Thanks Roy for the info on your setup. I was not aware of the Bogen 3420. Very nice photos. The pics you took at Viera Wet Lands are truly superb.

    Thanks a lot Sout Fork. These give a pretty good idea of what your setup can do. These are nice pictures, all keepers. The Redstart in particular, taken at 150 ft, is a good example.

    Sout Fork, what was the size of your target ? Could you post some pictures of birds taken at a good distance with that setup ?
