    Help needed for a better zoom lens

    That looks like a good price but I would be extremely skeptical purchasing from that site. It does not look like a legitimate store. Most of the pages don't direct to anywhere except the home page, and the contact address is just a random house in California (use google street view to see). They...

    Best long lens for about a grand for D7200

    This can't be done. Nikon has engineered their teleconverters to only work with their own lenses. I think I've read somewhere that you can shave off some part of the teleconverter to get it to mount with third party lenses, but then you may still have issues with the electronics not working...

    Tamron 18-400

    I'd really appreciate that intercooler!

    Lens fine tuning

    I think another option is you can use the sigma dock (https://www.sigmaphoto.com/sigma-usb-dock) to calibrate the lens to your d3100.

    Focussing

    It may be an AF fine tune issue like Mike said. In case you don't know of a good accurate way of fine tuning, here's a link to a video I found helpful: https://www.youtube.com/watch?v=7zE50jCUPhM. There is a link to a focusing target in the text below the video.

    Tamron 18-400

    Hi all, For some background, I've been shooting with an RX10 IV for a while and enjoy it, but I recently learned of the existence of the Tamron 18-400. I do have a Nikon SLR and was thinking about the possibility of selling my RX10 IV and buying the Tamron, putting some money back in my pocket...

    Nikon Coolpix P900 on a grey day

    If the images are coming out too dark for your liking, I would raise the -1/3ev setting to 0ev (and again to +1/3 ev if they continue to come out too dark). You may need to readjust this on the off chance that you all do get a bright day ;) The widest aperture you can set varies depending on...

    Nikon Coolpix P900 on a grey day

    116mm is the focal length. The P900 is a focal length range of 4.3mm-357mm. Not sure if you want me to get into the details, but basically with the P900 you need to multiply this by 5.6 to get the "equivalent focal length". The P900 is advertised as having a 24-2000mm focal range, so if you...

    Cheap/Budget Superzoom Options?

    I agree with Den, the P900 is the one to get out of those options if you want to use it as a pseudo scope.

    Share video from canon 80D

    Hi Jon, Do you know how to transfer the video files from your SD card onto your computer? And which video sharing site do you want to use? I should be able to write up a short guide for you. -Michael

    Talk me out of Noctivids

    I think you've got a really nice lineup already. A full size 7x and 10x, with an 8.5x right in the middle, and an 8x32 for easy carry. Plus it's balanced with 2 leicas and 2 swaros.

    Thanks for sharing Skean. Those are some nice first shots!

    Arghhh! Need better quality than P90 better portability than 600m

    Thank you for all the information Justin! Not much for me to say except that I learned something :) I think I might give burst a shot, could increase the number of keepers I get...

    Arghhh! Need better quality than P90 better portability than 600m

    I think it largely depends on your shooting style and what you like to shoot. I only take pictures of perched birds, single shot at a time so 1 battery almost always lasts me the birding session. On really long days I can go through a battery. I usually bring 2 spare batteries just in case...

    Panasonic FZ82 or what?

    Swarovski must have fixed the glare issues in the SV 8x32.

    Hopefully Henry can answer that ;) I highly doubt he will since he seems content living in denial (though I'm sure he'll sell them due to glare not too long from now). But luckily Torview posted a picture through his 8x32 FP in post #85.

    Panasonic FZ82 or what?

    This is true, but the main appeal of the Sony is its compact size. https://camerasize.com/compact/#689.505,611.687,722,da,t

    Panasonic FZ82 or what?

    I don't think that's too old, but if you're seeing a noticeable drop in speed then that could be a warning sign and it may be time for something new. Have you tried different cards to see if the speed's any different? I used to own an FZ200, which is the same lens and sensor as the FZ330. It...

    Swarovski must have fixed the glare issues in the SV 8x32.

    Thank you for posting a proper picture peatmoss. Comparing to Henry's 8x32 SV pictures, the interiors look quite similar, with primarily 3 problematic areas on the edge of the exit pupil. Unless the interior of the 8x32 is much different, I wouldn't expect any different glare performance between...

    Binocular Scalability

    I think this scaling exercise is more trying to evaluate the low light performance of binoculars. As an example, with everything else equal, if you put a 8x32 and a 10x40 on a tripod at twilight, you should get an equally bright image, but you'll be able to resolve more detail with the 10x40...

    Binocular Scalability

    Really interesting stuff here Quincy, and nice write up. I really appreciate the graph. This is kind of a different measure for twilight factor, which is (magnification * objective_diameter) ^ 0.5. That calculation always seemed too simple to me though; I like yours a lot more. I hope others...

    Swarovski must have fixed the glare issues in the SV 8x32.

    In order to really know if the glare issue has been "fixed", we need pictures like Henry took in this post (the 2nd and 3rd pictures): https://www.birdforum.net/showpost.php?p=3251084&postcount=1 Can you provide pictures through your copy Dennis? It should be relatively easy, just make sure...

    Some ramblings on 8x32

    I think Zeiss has a longer eyecup for the conquest. If you contact them they should send one out to you.
