Re: "Affordable" Macro Lens for Nikon D5300
You had asked about aperture changing as you focus, basically when focus closer, you are moving the lens further from the camera body. At 1:1, you have basically doubled the lenses distance from the camera.
So the image from the lens is larger, and you get less light on the sensor. 2 stops for 1:1, about 1 stop for 1:2, darker.
Also nikon has an older 55mm that adjusts the aperture and stays at the set aperture on the lens as you focus closer.
I'd recommend an af lens. AF is a really big deal, imo, for hh. I push the shutter button down, and hope it will lock and fire before I move. Get a lens that is compatible with your camera, imo. Not having af and a meter is a potential pain, although I do use old alts a lot.
I saw a 150 sigma on keh.com for a bit over $300, I think it was canon. But you might check their site.
I like the longer fl , although I feel like a higher ss is necessary hh. More room between you and the subject, great for bugs.
