Summary: It's not bad. It's just really hard to focus if you're not in broad daylight or in a very brightly lit room. Even then, it's hard to tell if it is because of the soft blur that the resulting photos have. It's a fun lens that you can play around with. Although, I haven't replicated the effects that they're widely known for.
Summary: I actually used this to mount the cheap Diana lenses to a Red Epic digital cinema camera with the Canon mount. It worked! I shot a grindhouse style opening for a horror film with this mount and the Diana lenses. They loved the look. The reason I don't give it 5 stars is because it is a super cheap plastic adapter and is easily broken. Of course, for this price you could buy 10 of them.
Summary: I never saw in any review whether this lens could be used on a regular Diana plus...well my Diana is a plus and this fits just fine on it...and it stays on my camera . I paid a little over thirteen dollars for my Diana+ with a ring flash on an auction site...I can't use the ringflash with this lens...but I don't care...I love this little lens and can use the flash as an off camera flash..
Excerpt: Though this flash is designed for Diana cameras, with the adaptor, it works with any camera with a hotshoe. I use it on my old Polaroid Pack Film cameras. It provides just the right amount of lighting and it looks right sitting on top of a 1960's era camera.
Pros: Consistent Output, Easy To Use, Fast Recycling, Lightweight, Versatile
Excerpt: So far I'm loving my Diana +. It has taken a while to get use to how the camera works compared to some of its 'modern' counterparts. Make sure to actually take the time to read the manual and hey even read some stuff online about the best way to get the shots that you want. Overall I recommend he camera to anyone who is willing to take chances and do something different. It seems fragile to me so that's my only complaint. I always feel like I'm about to break it.
Excerpt: I am a semi professional that bought this camera as a experiment. I am still experimenting with it as I started by using it on "pinhole", the trickiest mode. The camera looks great on my shelf when not in use, next to my Zorki and Pentax cameras.
Summary: I use this on my 7D with the Diana F+ 38 and get that nice dreamy effects that you want from a plastic lens only problem is I haven't been able to remove the lens from the adaptor but if I really wanted another Diana lens for my camera I would just but another adaptor with it
