I noticed the 50mm has a very "zoomed in" look, but everywhere I read said that 50mm lenses are the most natural looking so I figured that's normal. Though that's not true for a crop sensor camera like mine? And I'd get a better "natural" look from a ~30mm (35mm?) lens instead? It's not a huge deal, I'd just like to know what's going on.

Thanks for the replies. Yeah just try to think about it as compensating. You want to go wider to compensate for how the crop factor will reduce the field of view.

Unfortunately, I don't have the $$$ to get both right now. Double unfortunately, the lens is less than a month old but the store I got it from only has a 7 day return policy on lenses. I guess I can try to sell it on kijiji for like $30-40 below retail. BANME.sh fucked around with this message at 19:50 on Jan 17, 2013 |

There's nothing wrong with continuing to use the 50 if it's doing pretty well though. Even with a 35 you'd going to have moments where you wish you could squeeze more into the shot. You may also be able to straight up trade your 50 for a 35DX from someone who's moving to full frame since the 35DX isn't super useable on FX.

Yeah I am going to keep the 50mm and just continue to casually sell it online while still using it. If somebody takes the offer, cool, if not, no big deal. It takes really pretty photos Thanks again for the clarification.

Keep the 50 around for portraits, shoot a lot of those while you save for a 35.

# ? Jan 17, 2013 20:27 |

The thing is I don't take too many portraits. Those I do take are usually just at social gatherings, and it'd be nice to have a wider angle to get group shots in without standing 100 feet back.

You should also be aware of how the focal length of a lens affects the perspective of the shot. This video does a great job of explaining it with examples. http://theslantedlens.com/2012/how-lens-focal-length-shapes-the-face-controls-perspective-a-lighting-tutorial/

My god the moire on the D600 at 720p/60 is insane. The same shot at 1080/24 is mostly fine. What's the science behind this? Resolution? Frame rate?

To give an unnecessary and undeserved response to a willfully obtuse complaint about an incomplete but not incorrect technical elaboration on some good advice: Focal length and sensor size alone determine your angle of view. The amount of the frame the subject fills is a function of the camera's angle of view and the subject's visual angle, which is a function of the size of the subject and the distance from the camera to the subject. Where you finally end up putting the camera relative to the subject simultaneously determines both the subject's visual angle and the image's perspective. Since echobucket was talking about the BANME.sh's situation with a fixed sensor size (crop), subject size (people), and likely framing (a group or individual portrait), changing focal length would indeed change the perspective by forcing BANME.sh to move the camera relative to the subject. I'll leave deriving the actual equation for camera-subject distance as a function of focal length an exercise for the reader.

Spime Wrangler posted:Focal length and sensor size alone determine your angle of view. As long as we’re being extreme pedants here, the mapping function of the lens affects angle of view as well. For 90° vertical field of view, a rectilinear lens would be 12.3 mm, a stereographic fisheye (e.g. Nikkor 15 mm) 14.5 mm, and an equal‐area fisheye (e.g. Nikkor 10.5 mm) 16 mm.

I shoot a D80 and D90, and I have a Tamron 70-200mm f/2.8. I was shooting some deer at a state park the other day and kind of wished I had a little more reach, so I was thinking about getting a teleconverter. Since my 70-200 is already a Tamron, I was leaning towards the tamron teleconverters, so my big question is 1.4x or 2x? Anyone have an experience with these? I've also heard people talk about the cheap Kenko telecoverters. Obviously the nikon ones are the best, but I would feel silly putting an expensive nikon TC on my inexpensive Tamron zoom.

The older version with the screw-drive passthrough (which is nice if you're using non-AF-S lenses). I'd look around KEH and whatnot too.

No content here, but just wanted to say that I upgraded to a D7000 this weekend (from a D70s) and hooooooly poo poo. I don't know that it's a hundred times better than my old camera, but it sure feels like it. I still suck composition, exposure, and creativity, but at least I know it's mostly me that sucks now Coming from the D70, all the controls feel great, having a dedicated button for everything (more so than the D70) is really nice too.

So my D5100 is an F mount, meaning I can technically use any F mount lens in history, but I'll lose features like auto focus and metering, correct? I can deal with manual focus but exactly how much of a pain is losing metering? Basically what I am asking is if I want to experiment with old/cheap lenses from ebay, what's the biggest problem I am going to encounter?

e: ^^^^x2 If you have a smartphone, you can probably use that for metering as there are reasonable metering apps for both ios and android. Over time you'll get a feel for it anyway, we largely 'had to' on film as the meters in all my film cameras were pretty much junk and less accurate than aforementioned smartphone would be Why are we talking about the cheap kenko TCs and not the PRO300 series Kenko TCs that are actually good quality (subjectively, as good as nikons'), cheaper than Nikon, and not hindered by deliberate lens incompatibility. Also, regarding the discussion about 50mm being 'natural' zoom, I suspect that there is variation on human field of vision, because on 35mm the 50mm lenses always felt slightly too wide angle compared to my eyesight. 50mm on APS-C feels about right for me, maybe ever so slightly zoomed in (maybe ~45mm would be about ideal).

The few lenses out there that can destroy your mirror or shutter mechanism are niche lenses you probably wont find yourself wanting. As for a smartphone meter, no. They are wildly inaccurate. Might be useful in a pinch during the day time at noon.
