Here is a link to full sized example photos on Flickr: Flickr Gallery Link You can pick this lens up on Amazon here. Here is a crop of one 100MM@f2 photo at 100% without additional editing: I’d personally consider that is producing a nice amount of detail, especially without any editing. There … Continue reading

Lens Review: Pentax FA 31mm f1.8 Limited

The Pentax FA 31mm f1.8 Limited was first offered in 2001 and is still in production as of 2011. It’s one of three FA Limited prime lenses.

Lens Review: Pentax DA 18-55mm F3.5-5.6 AL

This lens was available from 2004 until around 2008 as the primary kit lens for Pentax DSLRs. Currently you can find it around at used camera lens sites like KEH or auction sites like eBay. It’s easy to find and very cheap. This is actually my second AL lens as I sold my first and acquired this one when I bought a used *ist D camera body recently. The 18-55mm … Continue reading

Lens Review: Sigma 24-60mm F2.8 EX DG

This Sigma lens came out around 2004 as a reasonably priced higher-end zoom lens specifically designed for digital SLR cameras. It has a maximum aperture of f2.8 throughout the entire zoom range, which is its claim to fame to being considered a higher-end lens. The reason it was lower priced probably had something to do with the unusual zoom range, 24mm being 6mm short of most standard kit zoom lens … Continue reading

Lens Review: Focal MC Auto 135mm f2.8

One of the nice things about shooting with Pentax is that pretty much every lens that was made for K-mount will work on current DSLR cameras (the same can be said of M42 screw-mount with an adapter). There are probably a few exceptions, but I personally don’t know of any. This lens I’ll be looking at today is a fully manual telephoto prime lens with a large aperture. A lens … Continue reading

Lens Review: Zenitar 16mm F2.8 Fisheye

The Zenitar was one of the first lenses I bought after getting a Pentax *ist DS kit in late 2005. While I’m not sure exactly why I opted for the Zenitar over something more practical, I ended up buying one new from an Ebay seller as it was cheap, said to be sharp, and interesting due to the fisheye feature. Technical specifications for the lens: Lens Mount: K-mount Lens Construction: … Continue reading

Lens Review: Pentax DA 40mm F2.8 Limited

The DA 40mm f2.8 Limited on a Pentax *ist DS camera body shows just how small the lens is: When thinking of Pentax as a camera company a few things come to mind. Skipping ones not relevant to this article, one of the major defining properties of their gear are special pancake prime lenses that provide a quality camera lens with an especially small size. These lenses use a lens … Continue reading

Lens Review: Pentax D-FA 100mm F2.8 WR Macro

The D-FA 100mm f2.8 WR Macro is one of the newer mid-range lenses from Pentax, which was based on a long line of 100mm macro lenses through the years. The main purpose of a lens like this is to have the ability to achieve 1:1 magnification of the subject, but also allow for a good amount of working distance from the subject thanks to the 100mm focal length. Macro lenses … Continue reading
