Summary: This creates an interesting feel to images. However, no matter how well you focus it's not going to be super sharp. It's great for artsy type stuff, but I wouldn't use it too much for my paying clients unless I knew they were into that look.
Summary: Purchased this for Christmas for my dad. He has taken up photography over the last few years and has many "gold-ring" lenses, but has enjoyed some of the creativity that this allows. The pictures look good.
Summary: If you have nothing of interest to shoot, this lens will make the mundane interesting. If you have a nice photo in mind, your probably not going to want to use this lens. It's fun to play with, but I'm not sure it's worth $80... But for that matter, I'm not sure spending $2,000 for a lens is worth it either.
Summary: Been playing around with my new Spark quite a bit. Overall, it's rather quick to learn, but it's going to take a while to master. This is one of those things that will take a lot of practice to understand the lens and the operation. One of the biggest learnings is hold to hold it. I'm so used to holding the camera in one hand and the lens in another. But that just won't work here, it's too unstable.
Summary: This is a really neat lens, allowing you to take some really cool pictures. It's easy to install and use. BUT...be patient, it takes awhile to figure out how to make it take te pictures you see on the website. It's really best for spots or movement, not still shots. The movement makes the blurry part show up more. THis is a great lens to have in your bag, and good as a starter. I bought this as a gift, and I have the Lensbaby Composer for my Nikon.
Summary: This lens is FUN! You will not get perfect results every time, half of the shots that I get from it are not in focus at all. But that's OK, it's a fun lens to use, it has a unique look to it, and it is unique. The lensbaby website contains some excellent videos and articles to teach you how to use it. You will need to be taught how to use the lens, it doesn't work like a "normal" lens. Plenty of practice will be needed just to be able to focus with it.
Summary: With Lensbaby lenses you can bend the lens away from the normal parallel alignment to the camera sensor, allowing you to get some very funky focus effects. Having used the more expensive Lensbaby Composer before I quite like the effect you get from these unusual lenses, but the cost is quite high for an experimental special effect lens.
