Yeah, I love seeing Nikon n00bz bitch about not being able to change aperture in live view with their shitty chinese made, neutered, plastic G-lenses. Get a AF-D lens, you freaking imbecile. I'd rather change aperture with a ring than that stupid little thumbwheel anyway (or on Canon, by pressing a button and THEN turning a wheel with your index finger... Stupid)
But yeah... pro-quality lens for 170$? ummm yes please... It's got less distortion at all focal lengths than the 24-70 and the 28-70... and is made out of pure solid fuel booster rocket-nozzle grade Japanese steel forged from the caldera of Mt. Doom by Hattori Hanzo.. (but probably more like billet-anodized aluminium) so why the hell not? It was good enough that it was Nikon's main-go-to standard pro-zoom for like 15 years and zero people bitched about it because it wrecks face and doesn't have time for names.
The push-pull deal is actually pretty sweet for video. Super smooth for something like a hitchcock push - that said, yeah, Nikon's push-pulls are all backwards and I have NO idea why or how. my 80-200 f2.8 is the same way - yeah, got it for 250$ (!) - and it's got the same exact glass as the faster-focusing two touch D version that costs three times as much.
I really don't care about the noise the AF-D lenses make.. Who cares if it turns into a dubstep show? Who cares if the ring moves, don't touch it! Not that hard. Even if I'm doing street photography, nobody can fucking hear it (because guess what, you're in a freaking CITY), and it focuses just as fast as the SWM lenses, really...
Whatever. D-lenses are metal as fuck, and I'm stoked to have every focal length from 20-200mm (sans for 70-80, which sucks so who cares) locked up with 3 bitchin ass legacy Nikkor AF zooms. That I paid a grand total of 550 to get.
