I have no description, but that will change. This plastic lens is hard to manage, at it’s best it isn’t in focus. I’m still trying to work it, but it might be better done in post with just my 24mm lens. The Holga is about f8, so they say. My guess is f12. It’s definitely a traditional Holga, but I’m not so sure it’s for me. I want control. It introduces so much randomness that I have no idea what I’ll get. Not always a bad thing, but I’d prefer to control sharpness and blur and not let it be random. I’m a control freak, I guess. But it’s interesting to learn from the random.
After measuring, it’s about f/11. It is what it is, which means you don’t have any idea what it’s going to do. There’s a place for that. (It’s about 4 blocks away and serves Tabouli.)
Technically, a fisheye should be in focus from a few inches to infinity. This isn’t that. I can screw an adapter into the glass optics of my 24mm and get down to about 18mm. I lose some light, it’s hard to say, but I’d think it’s close to f5, give or take.
I do believe I could process this into something that looked like a Holga. But you have to know what you want to do that. Much thinking in the future. I hate that.
