Zeidora, you have quite the lens collection there. You are a little hard on the EF 180 f/3.5L macro - a little lens correction helps - the function of a longer telephoto macro is to deal with shy live subjects. In what way is the Zeiss 100 image quality better than the Canon 100L macro image quality? I have thought about getting a mid-length macro, and my macro focusing is manual (focus ring, moving stage, or "LordV method").
"LordV method": hold the camera and at the same time with the same hand hold a more-or-less vertically placed thin or medium-sized "stick" (hiking pole, even a collapsible fishing rod holder) either against the camera body or by hooking your little finger onto the stick. You now have a pivot point and can rock forward or back to get fine focus, using minor wrist action to adjust framing. I may try the string technique too - string attaches to the 1/4" tripod hole in the bottom of the camera, stand on string, pull upward. Our local botanical garden does not allow tripods or even purpose-built monopods in indoor spaces - worried about liability of people falling over the tripod, and the tripod obstructing traffic in a narrow space. The collapsible fishing rod holder fits inside my camera bag, and of course the string would fit in my pocket.
Hi Nancy,
You are right, I like my glass. I do understand the purpose of the 180 to bridge longer distances, and that is why I got it. Where I need even more distance, I use a 300/2.8 IS with extension rings.
I try to attach a couple of images (first time attempt, so will see).
First is an image of an orchid (
Diena polybulbon), same framing (more or less) with details blown up to show distinct lateral color in 180 macro, while the Zeiss has zero. The two blow up areas are highlighted with some squares on the main picture. Note, that the highlighted areas are by far not in the corner, so corner LC will be much more pronounced. Some here may consider the LC as negligible, but I want to show that there are lenses free of those defects. This was shot on a 5dmkii, so the effect will also be more pronounced on bodies with smaller pixels; I have a 5dsr on order.
I have not used the Canon 100 macro, so cannot comment on it. However, I have not seen any reviews that suggest it is on par with the Zeiss. Whenever I have compared Zeiss vs. others, Zeiss has come out on top. Zeiss vs. Leica stereomicroscopes, Zeiss vs. Swarovski birding binoculars, Zeiss vs. Hitachi/JEOL scanning electron microscopes. If you have a chance, try the Zeiss. It costs about the same as the Canon 180 macro.
My focusing is also manual (duh), also use focusing stages (manual and motorized Stackshot). In zoos etc. where I cannot use a tripod, I have used flashes. If you hold a rubber hood agains the glass, you can eliminate reflections. Some places don't like flashes either. Haven't done that in a while, rather go outside and shoot in the wild.
I have had 50 macros before, but then quickly "graduated" to the longer ones. First OM 90, then Nikkor 105, Pentax 100 (for underwater), Zeiss 100 CY, now Zeiss 100 ZE. For botanical work, I very much prefer the longer focal length as you can frame more freely and are less prone of introducing shadows with your gear/body. If you want the plant-in-environment shot, then rather go with WA. I used the 21 for that quite a bit, but that was occasionally too wide, so recently got the 24/2 and like it quite a bit for that. May workhorse lens is the 100 mm MP.
I have not used stick or string. I rather brace myself against wall, arms against chest. Or just enjoy without pictures. Last but not least, if you are really into it, contact the place before hand, and offer to make the images available. Some may then let you set up a tripod in off-peak periods. I work at a museum, and although I don't think we had such a request, I think we could find common grounds.
Second is a shot of a rattler (
Crotalus oregonensis) in the wild chaparral with 300/2.8 IS @ f/13 1/60s MF and extension ring, a 4' reflector brightening up the shadow on the rock. I don't see rattlers that often; I don't like the grass over the head, but was not about to remove it. The shot just gives an idea that this works pretty well.
Enjoy your botanical shooting.
