closeup photography: what possibilities in med format?
you didn't specify the range of macro and closeup magnifications you need: see http://medfmt.8k.com/mf/macro.html table at top highlights range of magnification vs. type(s) of macro setups recommended (per Muir et al.) in some cases, diopters will provide the coverage, in other cases, tubes or bellows are needed, then more specialized setups in higher magnifications... in the $350-ish budget range, not many SLRs outside the Kiev60 ;-) grins bobm PS see mf/diopter.html on diopter lens options; these are excellent for nature subjects where the center is critical subject area, not the corners and yield higher resolution than many macro lenses which are optimized for a flatter field response; Derek Fell in How to Photograph Flowers, Plants, and Landscape (HP books) is one of the world's best selling flower/plant photographers, and he uses a MF SLR with closeup lenses over more pricey MF kits due to higher central resolution, something I didn't appreciate until I saw tests at http://medfmt.8k.com/mf/diopter.html#beat This high performance with 2 element closeup lenses is esp. impressive when you compare it to actual macro lens performance at macro distances, which drop significantly (as in 40-50%) over infinity, despite the general view that these macro lenses are optimized for macro work (see charts on macro vs magnification at http://medfmt.8k.com/mf/macro.html ). PPS what's the best low cost MF SLR macro kit? IMHO it is the later classic bronica S2A/ECTL series, which had a nifty tilt/shift bellows ($200+) which is great for placing available DOF where you need it, also modest cost auto extension tubes ($50+), nikkor optics ($50-75+ normal lens..).. The older classic bronicas were unique in having removable helical lens mounts, so the tilt/shift bellows could focus to infinity, making all the lenses macro to infinity optics ;-) Other tilt/shift bellows in MF don't preserve infinity focus AFAIK, and most MF bellows don't have tilt/shifts Since it is a focal plane SLR, it is easy to convert lots of lenses to work with the system in macro mode too ;-) I use a body cap drilled out to mount a rear lens cap for nikkor 35mm lenses (http://medfmt.8k.com/bronhb.html and medfmt.8k.com/jpegs/bronbroc/bronnikon2.jpg for homebrew examples). The 57mm diameter by 1mm pitch threaded lens mount inside the bronica lens mount makes it easy to create your own lens mounts too ;-) The ECTL even has auto-exposure modes, or you can use metering prisms on S2A/EC series. -- ************************************************** ********************* * Robert Monaghan POB 752182 Southern Methodist Univ.

It's a sharp lens that works very well for close up work but a macro/enlarging lens would be better. The Rodenstock and Tominon macro lenses for the Polariod copy cameras are fairly plentiful and make good macro lenses used like this. You can also get them for not much more money with a leaf shutter, if you want the lower vibration this offers. Like this? :-) http://miss_stephe.tripod.com/ysaron.html -- Stacey |

Bob and everybody who replied,
thank you all for your helpful answers and suggestions. I think the Kiev 60 seems to be the way to go. It is small, light (well compared to a c330...) and cheap. Enough for now. Perhaps in the future, i will spring for a brand name... Bob, a very special thanks to you for the enormous detail and insight you provide me with in your answers! Sri |
