What wide angle lenses do you use, or know of that are good for extra-wide angle on an aps-c/dx camera like a D7100? Looking for scenery, panoramas, indoor interior design, and realize full frame is better suited. Realistically I'll only spend a few hundred dollars, but don't avoid talking about the really expensive stuff. My perception is manufacturers reserved the really nice stuff for full frame and avoid trying to compromise wide angle on the smaller sensors.

Not all women are alike, but my mother enjoys having her hair and a little makeup done. If there is someone available that she would enjoy having do that, like a daughter or friend, she might enjoy that.

I mass-scanned about 1000 slides shot by my grandfather spanning a 50-year period. I didn't pay close attention to the results until I no longer use the scanner or the slides, and then found that the dust removal routine removed many many pupils and left a skin-colored patch where the eyes should have been. Often only one eye at a time ona subject was affected. It still makes me sick thinking about it since these are the only remaining images I have of my mother from that period.

I have one. I searched eBay for something like 'red dot hot shoe". Basically it's a regular holographic sight with a hot shoe to picatinny mount. I went cheap and I recommend doing the same. A little play in the mount allows you to quickly fine-tune the aim without tools. Each time I mount it, I set the camera on a tripod or stable surface and move the sight until the reticle is exactly in the center of the single center-focus square. After that, I set the camera and lens to autofocus appropriate (fast) exposure settings and point and shoot at whatever is moving fast above. The limiting factor is the speed at which the autofocus can aquire the target and focus. If the distance is constant you can manual focus, once and leave it. You are not looking through the lens while you shoot. I still get lots of blurry and um-centered shots, but I've also gotten some fun aerial acrobatics by eagles and ospreys and fighter jets.

You can also check your autofocus calibration. Resources online can guide you through it. My D7100/18-300mm autofocuses a little behind the subject and was corrected by calibrating in the camera. This only affected full open aperture.
