FX lens on DX body?

So.... I'm guessing the SB-700 is good? I researched it a little.

The best would be a SB-910, most affordable would be a SB-700...or SB-600 if you can find one used (Nikon discontinued them in favor of the SB-700)

Unfortunately, neither can be used remotely without buying anything else since your D5100 doesn't have commander mode built in. You'd have to buy a flash trigger.

Normally their very expensive for quality ones, but you can pick up a cheap
cowboystudio set (transmitter and receiver) for $20 that works really well for the price...

The only downside is that you cant use TTL or any of the auto modes on the flash when on these wireless triggers. You would have to set the flash manually.

Now you see why having commander mode is a big deal. If you did, and used a Nikon speedlight, you would be able to set the power level and flash exposure compensation from the commander menu on the camera without ever touching the flash.

Yeah... Commander mode would be a giant plus. I will get a D800 soon enough. I want to learn all the basics, then upgrade maybe in 6 months. Its also going to take that amount of time to save up enough money.

If you're taking photos of your fish or something you'll want your flash off camera. If you're getting a d800 you'll want glass to match.

The only different thing between 700 and 600 is the white card on 700 I think. But you can DIY and save around $100

Soo...looking at lens again. What is the best all around telephoto? Would be nice to have zoom capability, but prime is okay.. Budget is $500 or around that.

I was looking at the 70-300mm but all the pictures I see coming off of it don't seem the best. Also, I think I can save $400 by buying the AF one and it doesn't come with VR, which I don't mind. I can barely tell the difference on the lens I have now.
