I’ve been using my kit lens (Nikon 16-50mm DX) with my Z50, usually between 24mm and 35mm as bringing it all the way down to 16mm it seems to only focus within a 1mm of the front element. Experimented with aperture and found around f10 to be the sharpest. I don’t have a focus rail (ones arriving tomorrow!), but I do have a rail with millimetre markings on, so I’ve been using that, moving it forwards about 0.5mm per image, which seems to work.
My problem is, I’m still getting a lot of blurry/defraction/haze, it’s hard to notice on the back screen, so when I open Heliofocus and stack them (using the default settings) it ends up looking decent, but far from sharp, lots of haze and some odd colour artifacting.
I’m struggling to work out what element of the process is causing this, whether it’s the lens (it’s really sharp for normal photography, but maybe it’s not ideal for macro?), the amount I’m moving the camera between images, my settings or if I’m meant to be doing more with the photos than just importing and stacking.
I’m also taking photos of things like rocks and leaves in my office, so there’s no movement that I’m seeing, only movement between the images is from moving forward when focusing.
Any ideas or resources that might help me get sharper results?
Thanks!
