All three are great lenses, and I own the 50-100 & the 85/1.8. Geez, it's hard to not like the 85/1.8 for every Nikon owner. Tell you what, it's MUCH easier to carry around than the 50-100. That ...

My 50-150 OS didn't focus accurately on my D7100 until I sent it back to Sigma.  Quick turn-around (sent it in with a detailed explanation of AF issues). The Sigma dock is clearly better than any ...

Get the USB dock.  If the lens is off, at all, at the four adjustable distances, and focal lengths, then make those adjustments.

Phenomenal lens for sure.  Made when Sigma decided to start building some of the best lenses made by anyone.  The weight/size is a factor, but as they say, "There's no free lunch."

Nothing.  Straight from NEF, via CNX2.  I didn't apply NR.

The D7100 captures great images at ISO3200.  If you can't, it's not the camera...

Sharks are not interested in people... Less than 100 attacks worldwide , annually . It IS an adrenaline rush for sure, but I don't have a death wish.  Divers in clear water are RARELY attacked. If ...

Thanks for that advice.  I was thinking of adding a light.  Perhaps even a video LED light. It's also important to screw-in the black ring that keeps the inscription on the front of the lens from ...

Yes, that's correct.

Thanks all!  I had low expectations going in because I'd once rented a housing for my old D200, and didn't think the J1/WP-N1 would come near... I'd still rather have my D7100 in a housing, BUT ...

The Nikon WP-N1 housing that used to retail at $600.00+ now sells new at $49.00. It's good to 120 feet underwater, and so I picked one up, along with a used J1, for which it is designed... Here are ...

A few spritzes won't be a problem.  If you need to remove a drop, just dab, don't wipe. And obviously, don't drop the camera in the water.  I've gotten full-on big rain drops on my D7100.  No ...

A second-hand Sigma 50-150/2.8 OS might fit the bill.  Super sharp.  Heavy.  If it needs focus tweaking across the zoom range, you'd have to send it to Sigma...  But that's true with a lot of ...

What a fantastic image.  And with a D7100!   ;-) Phenomenal.  Wish it was mine...
