I've just learned that my D7100 has an option to change the crop ratio to an (additional?) 1.3x. In quick comparison testing I can see that my image is indeed "closer" with the 1.3x. What can anyone tell me about this option? I have a couple of points I am concerned about and would appreciate any input.

My options for lens use are 35mm 1.8, 18-140mm variable, 80-200mm 2.8, and 17-55mm 2.8

* Will I get any vignetting, pin cushion or barrel on my images

* Will this decrease my image quality in any way.

I am thinking this would be a great feature for weddings where I am limited to the far back of the church. Thoughts?

I asked the question a while back about my D7100 not able to scroll after zooming in except by constant tapping the arrows. After doing a Google on it, I find out that several Sigma lens are causing the problem. My 17-70 2.8-4.0 macro stabilized lens is the culprit. If I turn off a/f and IS on the lens, the camera scrolls as it should. You can also wait 40 seconds or so and after a "clunk" it works also. Would like to see if Sigma has an answer for that. I really like that lens. Of course Nikon could care less.

My girlfriend has 'stolen' my D7100, two zoom lenses, one flash and a few other odds and ends. She went with her girlfriends this weekend and we loaded up my gadget bag with her gear to keep it safe while they had more than several drinks. She told me, with a huge, adorable smile, that I probably need to buy myself a bigger camera bag... ;-)
The bag that she has 'stolen' is pictured below. It came with my D3200 kit and is (was) my only bag. I think I may want another Nikon bag, not sure yet, but not another one of these because my D610 was a little too wide for this narrow bag. I could use some advice and would love to hear what bag you own. I don't want a huge bag, maybe something that is a little bigger than this kit bag with lots of pockets and can accommodate a D610's width and several accessories and lenses. Thank you.

I have been trying research for a new dslr I currently have the Sony A77 ! I do a lot of sports mainly football and scenery plus portrait. I do not mind spending a bit of money if needed but on the other hand only want to spend what's needed. In addition looking for a camera where I can purchase some nice 2.8 high zoom glass. Lots of cropping and blowing up so pixels would play a part. I am not sure if I go with Sony A99, Nikon 810 or canon eos I hear a lot of personal opinions getting confused ?

Thanks

I am photographing at a Rally (offroad motorsport) which is a 3 day event. It's hot and unbelievably dusty, but a blast to shoot. On the last day I find sweet spot on the course where I figure that some of the cars might be doing some high speed four wheel drifting. So I setup myself on the inside of the bend. The course goes hot and I am catching some great shots on this corner. I am shooting on burst mode as one of the cars blasts through. Click, click, click then suddenly crunch, crunch and the view finder goes black. After the dust settles I pop the lens off and my worst fear is realized when the mirror tumbles out of the camera body on to the ground. Thank goodness I kept my old canon rebel in my kit. As I still had the rest of the days stages to photograph and more importantly the awards ceremony. Always carry a back up!
Anyone else have any stories of catastrophic equipment failure?
