72mm, no step down needed. The rings themselves are pretty thick, which create vignetting at Z00, but hey, they were cheapo... I'm sure a quality one would eliminate that.....
nice dude.
I tried some closeups with a cheapy x4 mag filter. But I could only get about 4-6 inches away from the subject. Anything closer I couldn't get to focus.
How close were you to these subjects with your +4? It's crazy how these zoom lenses can get out of focus at the movement of a centimeter.
most of these were 1cm away fromt he lense. I could basically touch them with the lenses. This is partially due to the width of the rings on these particular ones.
How far were you zoomed in? It shouldn't be possible to focus so close with so little diopter power! Very interesting. A +10 would theoretically only allow you to get just under 3 inches from the lens with the lens at full telephoto.
Argh! Of course! Smaller focal lengths will start closer to the lens to begin with so you can focus closer (thus the 1cm or so). My bad! I was just rather curious how that worked!
Yep, it should put you just under 3 inches. Is there any limit as to how much power you can add to the lens? Yes and no. You can keep adding lenses but at some point it will be impossible to shorten the focal length of the camera further. I don't know off the top of my head how much power that would be though.
I did some test awhile ago, stacking lenses together, I didn't reach a point where I wasn't getting closer to the lens, and I didn't use the +10 diopter, which means you can probably get quite a bit closer than I was in my test. Why you'd want to get any closer can be questioned though.
Cant be beat for 30 bucks. The guy lives right down the street from me so I went and picked them up today. There is +1,+2,+4 & MACRO in the kit and they come in a nice pleather flip out case.
