The 10-20mm lens is one of Nikon's "AF-P" lenses. You need to make sure your camera is compatible before ordering.

From NikonUSA: AF-P DX NIKKOR 10-20mm f/4.5-5.6G VR

Yes, the UHH search feature is terrible. Instead, you should use Google's Advanced Search to search the "www.uglyhedgehog.com" domain. Google will search all of the text, not just the title. Try it. very useful.

Check out Western Digital "My Passport". It's a battery operated, portable hard drive with an SD card reader built in.

A better, much cheaper option is to get a "Soligor" 400mm f/6.3 lens from the 1970's and 80's. This Japanese lens was sold under several different brand names. You can find them on eBay for about $40. A good copy is actually quite sharp (especially on a APS-C camera), and just as sharp wide open as at f/8 or f/11. T-mount design, so you can easily modify to fit most cameras for a few dollars. The one I have came with a Nikon F-mount. A tripod helps, especially if you are trying to focus on something close by, but I have used it hand-held in sunlight.

I'll mention one important advantage of the D7200 that is not obvious when comparing technical specs: usability or ergonomics. As you get away from entry levels cameras, you may get better performance and more features, but you also get a camera that is easier to use. Compare pictures of the back, top, and front of these two cameras. The D7100 has a lot more buttons and wheels. While that seems more complex and confusing, it really means you get to use more of the functions without having get into the menus. It also allows for more manual control of the camera. In auto mode, both cameras take excellent photos. But if you're considering a DSLR, then at some point you'll want to get away from auto, and being able to directly control the camera will make for a much more enjoyable experience.

You shouldn't miss White Sands Nat Monument for an out-of-this-world experience. You could continue on through Cloudcroft to Carlsbad Caverns for a non-interstate route. Then rejoin I-20 around Midland-Odessa.

You can use the Sony 200 lens with an adapter. But it might not be worth the adapter cost for a cheaper lens. The A6000 uses the newer e-mount lenses.

What aperture are you using? A photo taken at f/1.8 will have a very narrow depth of field. Try f/8 and see if more of your photo is in focus.

I have the same lens, S/N 572196, cost me $250 from KEH a few years ago. Nikon made this particular 300mm lens from Nov 1981 to about 1994, with serial numbers 550181 to 584206. It's a great lens optically, but tricky to focus on a DSLR and I almost always use a tripod.

I think you can sell it on eBay for more than you paid for it. List it as "buy it now" for $250 with free domestic shipping, and be patient.

Try it again. It worked fine for me: uploaded photo, cropped it, saved it. No problems.
The photo needs enough empty space around the head so that you can size it properly, center the head, and still fill the 600x600 box before cropping. If you can't do that then you need a different photo.
(I'm using Windows 7 and the Mozilla browser, but I doubt that really matters.)

Flickr is a great site to browse if you want examples of photos taken with a particular lens. You can search by lens. This is a Tokina 11-16mm group. Lots of other also.

Any experience with Tiger Direct before 2016 is no longer relevant since they are now owned by a different company. Reading the Wikipedia article, it sounds like they were never that reliable anyway.

If this is a typical morning walk, I don't think you have much to complain about! Nice neighborhood!!

Actually, 1/8 sec is probably about right. It depends on the effect you are looking for. But usually you don't want to completely smooth out the details of the moving water with a very long exposure. I start at 1/10 sec and then adjust up or down to see what looks best.

This photo was taken during last summer's drought in central New York. With very little water, I had to increase the time to make it look like there was more, about 0.6 sec.

Another reason to question the honesty of Abe's of Maine is that their "list prices" may be fictious allowing them to claim a bigger savings than you will actually receive.

For example, their list price for Nikon 200-500mm lens is $1499. The price directly from Nikon since introduction has always been $1399.
