Review: SLR Magic Bokehmorphic (Sony NEX Cameras)

by Chris Gampat on April 3, 2012

Playing with Bokeh can be very fun. We previously reviewed the DIYPhotography Bokeh Masters kit; and were quite smitten with it. Then recently, SLRMagic announced their Bokehmorphic unit for NEX cameras. As a lens with a constant f2.8 aperture at 28mm, it’s quite an interesting piece.

But it has its quirks, and SLRMagic didn’t quite do the research into how they could have made this lens even better.

The lens sells for a street price of US-$ 1,099 and is available for pre-order at B&H Photo.

Pentax has announced the introduction of a new super wide-angle lens for their 645 medium format system, with the particularly long official designation “smc Pentax D FA 645 25mm f/4 AL (IF) SDM AW”. On the 645D, Pentax’s digital medium format camera, the lens offers an angle-of-view corresponding to that of a 19.5mm lens on 35mm full-frame—that’s quite wide! Mounted to a film-based 645 body (to which it is compatible as well), it gets even wider: 15mm-equivalent. The lens that was originally scheduled for sale in summer 2011 comes with full weather sealing, dual aspherical lenses and a circular polarizer filter.

Hacks are awesome: especially in the photography community. Lens hacks are even awesomer, like what I did for my Canon 5D Mk II. That’s why this hack appeals not only to the Polaroid lover in me but also the hacker. Filmwaster forum member Ludoo sugru’d  an old Angenieux 100/f4.5 off a broken Kodak 620 Special 6×9 and attached it to the front of his Polaroid Land camera. The results are an example of the photo to the right.

Doing this isn’t easy though; Ludoo still has to calibrate the rangefinder to work with the lens: and that’s easier said than done. There will be lots of trial and error going on there. Still, it would be awesome to see just where this goes.

Review: Zeiss 15mm f2.8 (Canon EF Mount)

by Chris Gampat on March 16, 2012

We’ve been testing the (quite literally) recently announced Carl Zeiss 15mm f2.8 lens for a little while now. Rumors of the lens first appeared online and to be very honest with you, I thought it to be impossible. But we’ve tested lots of Zeiss lenses on the site, so I reached out to them about it.

Indeed, the rumors were true. The lens is real: and here is our real world review (or we like to call them: field review.)

Editor’s Note: If you liked this lens, take into consideration that the new lens is already available for pre-order from B&H Photo in both Nikon and Canon mount. Please remember that clicking the links in this post and then making a purchase (whatever it may be) helps to keep this site alive.

Op/Ed What Pentax Got right with the K-01

by Gevon Servo on March 9, 2012

I’ve been saving every single penny for a new camera. What I want is a second body to go along with my D90 for street photography and events. When Nikon announced their mirrorless camera, it was an option I initially considered, but I was underwhelmed after testing it. The Nikon 1 series looked good on paper, even with the small sensor. When it came to lenses, however, I had some serious issues with it. When Pentax recently announced the K-01 the first thought I had was, “They got it right!” [click to continue…]
