Here is the dilemma . I shoot action sports, concerts/bands events and nature. I have a Nikon d810 and d7000 and I'm looking to replace the d7000. Here are two camera setups I'm mulling over. One : d500 gripped with sigma 8-16, 18-35 art and 50-100 art. I want the 1.8 f/stop for the low light work I do. Or The new Fuji X-T2 gripped with 10-24 f4 stabilized and 50-140 f/2.8 stabilized. I already have the Sigma 8-16 f/4.5-5.6 and Sigma 18-35 f/1.8 art. I'm asking this because I shoot bands a lot shooting super wide angle over my head using live view. I was told the Fuji will shoot much better with the back screen overhead because it shoots using phase detection.

We have one of each accumulated over a period of time...Sig 150-500 on a d5200...Tamron 150-600 on a d7100 and a 200-500 Nikkor on a d810.

The Sig amd the Tamron are both excellent lenses...and I dont think anyone would be disappointed all tho the Tam is very slightly slower to focus...But the Nikkor is slighlty better than both...its a monster on a FF...but you would be hard put to tell the difference in a print.

Edit: so if you see yourself upgrading to a full frame at some point it time get the Nikon 200-500

You left off the biggest one of all at the moment, my candidate/your candidate/ their candidate.

I encounter this form of bias quite often when I bring up the Libertarian party and their candidate, Gary Johnson. Many folks I communicate with, or attempt to communicate with, aren't interested because they know what they know and that's the way it is and they're right and no one is going to tell them otherwise.

Is the glass half full or half empty?!

Actually a trick question, but most don't see or realize this. Unless the glass is in space or a vacuum, such as space, it is always full. It may contain half liquid or whatever, but the empty half isn't really empty, it just doesn't contain the same substance as the other half. A half a glass of water contain water and air, therefore, the entire volume of the glass is occupied by something, therefore the glass is full, not full of water but full none the less.

What were we talking about?!

Two weeks ago, I was on a photo shoot. I was just setting up when "it" happened. I dropped my camera. When I heard the sound of glass breaking, I feared the worst, the lens. I got "lucky", I only lost my polarizer and uv filter. I was very happy it was not my wide angle lens. I had my lens cap on, but I guess it got knocked off the filters took the hit. I have always used a uv filter and now I am glad I use one.
Both filters will be replaced next week. I won't complain about the cost, because I could have been looking at a new lens.
