A Clear History of Glass
I’ve written about glass, as in lenses, for years now. But I’ve never looked into the history of glass as just a substance, because, well, who cared? When I accidentally did some reading about early glass, though, I was rather amazed at just how important it was. So I thought I’d write about the…

I’m Gonna Party Like It’s 1995
I doubt any of you remember it, but 1995 was the coming out party for Digital SLRs. There had been digital cameras before then. There had even been digital SLR cameras of a sort – modified cameras tethered to a hard drive — before then. But in 1995 camera makers released digital SLR cameras for the…

Assumptions, Expectations, and Plastic Mounts
Photography companies love catchword marketing. They like catchwords because photographers make assumptions about what those words mean, even though the words really don’t mean anything. So basically, they say nothing, but it makes you believe something. Two of my favorite examples are…

Iceland Spar: The Rock That Discovered Optics
Every year, I can’t think of anything I want for Christmas. So this year, I was pretty excited to come home and tell my wife, “I know exactly what I want for Christmas. A nice big piece of Iceland spar.” I even sent her a link to make it easy. (It’s certainly a comment on our times that I sent a…

Metabones, maker of the impressive Speedbooster adapters is back at it again. When the Speedbooster first came out, I wrote about it being like magic, increasing the aperture and field-of-view of Nikon and Canon full-frame lenses mounted to NEX and micro 4/3 cameras, while maintaining or even…

Photo Geek Contest 2013 Winners
I am the poster child for that old saying, “Be careful what you ask for. You might get it.” I thought it would be fun to have a little contest just for the Photo Geeks who read my blog posts. I thought maybe 10 or 15 people would enter and we’d be like the 8 year-old soccer team: Trophies and pizza…

The First Annual Photogeek Geek Photo Contest
I’ve been writing a lot of geeky testing stuff for the last couple of weeks, most of which can be summed up as ‘take some pictures; if they look good everything is fine.’ So last weekend, I went out and took some pictures. It was pretty fun. So much fun that I thought maybe I could have a photo…

There Is No Perfect Lens Test, Either
In my last article, I wrote about the fact that every copy of a given lens has some bit of sample variation. This affects lens reviews, whether lab-based or photography-based, because the copy they tested will be just a bit different from the copy you buy. I suggested, that if you want to get a…
