I've had hold of the new PhaseOne 6x4.5 camera for about a month now, and to be honest it's taken some getting used to.
The system is NOT designed to this sort of work - not by a LONG WAY - and when Kev and the guys at TFC asked me if I'd have the gear on loan to try and replicate some of my macro work I did make my reservations apparent.
My main concern was, and still is, the 120mm f4 macro lens. My usual focal length of choice is 180mm on an APS-C camera, and effective 270mm angle of view - and the Mamiya macro lens that couples to the PhaseOne only equates to around 75mm. This is WAY TOO SHORT and gives massive problems with its huge angle of view.
The main problems are, firstly the need to be very close to the subject in order to obtain close-up detail shots; and secondly, the wide angle of view leads to more depth of field, which plays holly hell with the backgrounds.
The published minimum focus distance for this lens is 1.3 feet, but I don't know where they were measuring from when they came up with that measurement - this image was shot at about 8" from the front lip of the lens hood.
Full techs are:
1/4sec @ f11, ISO 100
This is a 57.3Mb crop from a 92.8Mb original - so pretty hefty, but the lens angle of view and minimum focus distance precluded me from making the subject any larger in the frame - hence I've had to resort to cropping.
If only there was a 400mm macro! Mind you, 250mm would be a god-send....
