Title: Inside The Machine
Post by: lelouarn on June 17, 2014, 02:39:38 am
Hi,
I like the picture - I've always enjoyed old machines and warehouses. But what intrigued me was that it was shot with an A7r (full frame) and a Zeiss Touit (lens for cropped sensors). Why would you abandon 21 megapixels to use the Zeiss lenses ? Are they that good ? I wonder if there's a article coming on that subject ?

Right now there is nothing wider than 24mm in native FE mount, though a 16-35mm f/4 will be here this year.

I was familiar with the 12mm Touit from work I did with it on the Fuji X1 last year, and think very highly of it.

As it turns out, the 12mm Tout covers mor than the APS-C format. In fact its coverage is closer to 1.3x than 1.5x. This means that on on A7r one gets about 16mm coverage and a 21M file. Just needs cropping out the corners.

Fantastic lens, sharp to the edge of coverage. Priced well, and there's nothing else for the A7 series that's as wide at the moment.

Currently Zeiss is doing a Touit lens "Blowout" in both E and X mount $200 instant rebate on either the 12mm or the 30mm or buy a set of both Touit for $920 which is an $800 instant rebate or like getting 1 lens free. Both of those lenses cover almost the entire FF A7series sensor (as Michael stated) . Another good choice in E mount is the Sony Zeiss / Zony 10mm to 18mm wide zoom which actually covers more of the FF sensor than the Touits(at some of the focal lengths). WhaT you do need to do is shut off the menu driven function in the A7 series body that auto turns the sensor to APS-C when using an E lens not coded FE.  This was alluded to in the excellent recent article on wides on the A7.

Michael that image reminds me of my first job in the early 1960s. One part involved a visit to a working stationary steam engine station; pumping water for London's East End. The inside of the station was immaculately maintained and I, being fascinated by the moving machinery, stepped off the rubber matting that formed a path to the office I had to attend. The next moment a shout went up "Get orf that bleedin' floor.."

A little while after, my first visit, the steam engine was replaced by an electric pump; more efficient but less romantic!

A Zeiss '16mm' at that price, sharp edge to edge is rather a nice thought actually...
