Review: Canon PowerShot SD780 IS

Walter Zapp would be proud. As you can see from the photo above, the SD780 is similar in size to the Classic Minox B, a camera that was designed “to be with you always”. But it’s shape is much more practical for those of us who are photographers and not spies.

Video on the Canon Powershot SD780 IS

I’ll level with you; I’m not a video person. It’s never held that much of an attraction for me. But even I have to admit that I’m fascinated by the fact that pretty much all still digital cameras come with some form of video. And the Canon SD780 is pretty amazing in this regard. In fact, it was a deciding factor in its purchase.

First Impressions: AF NIKKOR 20mm f/2.8D

I finally received my Nikkor Ultrawide prime today. I’ve been debating this purchase for a while now, but if I’m going to have at least one AF-D lens in my collection, it might as well be the most compact of them all and be compatible with a wide variety of bodies and uses.

Review: Samyang 500mm f/8 Mirror Lens

Samyang/Phoenix 500mm f/8 Mirror (Catadioptric) Lens

Mirror telephoto lenses, often referred to as reflex lenses but more accurately called catadioptric lenses, are frequently misunderstood and mistaken for poor quality. In reality, the catadioptric system is an ingenious telephoto design which reduces size, weight and cost when compared to refractive designs of similar focal length. Optically, it virtually eliminates chromatic aberration. But, like all advantages, they come at a price.

Nikkor 16-85mm f/3.5-4.5G: Six Primes in One

The AF-S DX Nikkor 16-85mm f/3.5-4.5G ED VR has six ideal focal length designations on the barrel, which are my go-to numbers. Although DSLR zoom lenses are continuously variable, I find myself going straight to these numbers first, depending on the subject matter.
