Macrophotography at a distance
Short list of macro solutions for 1:1 (ie. subject width 36mm) at a long working distance:
|Olympus ZD 50-200mm||Nikon Micro 200mm f/4D IF||Canon EF 180mm f/3.5L macro|
|working distance||~0.9m (requires 2x TC for 1:1)||~0.3m for 1:1 on full frame 9FX);
~0.5m for 1:1 on DX
~0.6m for 1:1 on FX with 2x TC
~0.9m for 1:1 on DX with 2x TC
|0.29m for 1:1 on full frame;
~0.4m for 1:1 on APS-H;
~0.5m for 1:1 on APS-C;
~0.9m for 1:1 on APS-C with 2x TC
|effective f/ratio||f/3.5 at 200mm setting (ie. 400mm in 35mm reach)||f/4||f/3.5|
|image stabiliser||yes via body||no||no|
|focus range limiter||no||yes but doesn't help macro shots||yes but doesn't help macro shots|
|ring flash||non SWD lens only, must hand hold for SWD lens||no||yes|
|wireless TTL twin flash||not yet, but via usual flashes||yes||no but via usual flashes|
|very versatile lens and the TC20 is of the
highest quality which makes this an incredible 800mm hand held portable
lens as well as a very useful macro for nature and a great portrait lens.
needs the TC20 for 1:1 macro but what a nice working distance!
|if you are serious about your nature macro work,
then this lens combined with a D300 and Nikon flash system may be the way
to go, but lacks the versatility of the Olympus lens.
BUT if you are not carting around your flash system and tripod, the lack of IS will limit you significantly.
|similar comments as for Nikon, although the Nikon has a better wireless macro flash system.|
