Mirror lenses are also referred to as CAT lenses, which is short for catadioptric, hence the name for this blog.

If you don’t know anything about mirror lenses, I recommend that you read SLR: The CAT did it, an entertaining and informative article by the late great Herbert Keppler.

What you will find on this blog is an assortment of information about mirror lenses and photos taken with them. We are not suggesting CAT lenses are the best, nor do we expect you to go out and buy one, but we do think CAT lenses have a place in modern photography and hope that this blog will help people realise this.

While we will post a lot of photographs taken by the writers of this blog, we welcome submissions from readers. In fact, if you have a mirror lens sitting in your closet, forgotten, we deman that you mount it on your camera, take it out for a spin and e-mail us your best shots. We will feature them on the blog, with complete credit given to you, and a link to your online photography gallery if you have one.

We want this to be as much our blog as it is yours. We hope this will become an online gallery filled with quality CAT photographs…of the “other” kind
