So, if anyone read my welcome post, you know my background. If not - im microscopist with growing interest in "normal" photography. So for me, it's like: Microphotography -> Extreme macro (here is where my knowledge ends)-> Macro -> Wildlife -> Landscapes -> casual snapshots. I got a6000 which is great camera for micro / extreme macro (imo best, with possible slight edge for a6300 / a7r2). PART 1 (reviev part) For microphotography im using Nikon Microphot with DIC and fluorescence, all Nikon CFN Plan Fluorite lenses and some gap-fillers (nikon tend to be quite expensive ) from PZO (which are actually extremely cheap and pretty decent lenses - great way to start with micro). Coupled with Metz flash - awesome little thing. No idea why microscope manufacturers dont produce micro-flashes (waaay back ago Leica did that) Exaple shots: Tradescantia sp. "leaf hairs" in fluorescent light: Human cheek cells in fluorescence: crystalized sugar in polarized light For extreme-macro i've got: own build set-up based on manual focus gear, bellows and low-power micro lens / enlarger enses. Taking photo with this take hours, post-processing take days, and since my HDD died i've got only few shots left (not super quality - extracted from my compressed pdf master degree work ). Domestic fly head Ladybird in fluorescence For macro... im new here. Already own extension tubes and SEL30MF3.5 Dont have any spectacular reasults here (yet! i hope). So i've been shooting various insets and flowers for few months with SEL30M, SEL50 and SEL55210 trying my strenghts on the subject. With this kind of magnifications it's very shallow DOF and i dont own proper setup for field focus stacking (yet!). My thoughts on the subject: -Sel30M - forget it. Its great lens, give true 1:1 but lacks proper working distance and OSS (wonderfull little thing if you aint carrying tripod, focus rails and flashes with you). I can recommend it to you if you're interested in shooting coins or stamps etc. But if you're into insects / flowers (deep stacks), forget it. Distort too much for focus stack and insects are too spooky. For casual "snaps" i cant find it anyway superior over SEL1650. Gonna sell it. All shots far away from 1:1... impossible to get closer. -SEL50F1.8 - amazing glass, totally love it. Had SEL35F1.8 for a bit, but decided to sold it and keep 50 which is a lot cheaper (when using PZ1650 - i've found myself using either 16 or 50, so couldnt justify that extra 35 if results are quite similar with 50 minus two steps). So since i like it so much i've tried it on kenko extension tubes. It goes around 0,5x with them with similar max aperture like SEL30M but much better working distance at that magnification. But it got one problem - focusing only in appropriate distance. You're too close or too far to subject - no luck. Thats really very troublesome with this lens, so i cant recomend it... tho if you got sel50 , you can get reasonably good close-ups for cheap (payed around 28USD for new set with metal mount - avoid plastic one) Cetonia aurata -SEL55210- now thats GREAT lens. I find myself keeping it on camera for 90% of time. It has reasonable close-up capabilities about 0,3x for itself (good for medium/big butterflies with super comfortable WD of around 1 meter). But real magic is when extension tubes are on. It's now a close-up monster with accesible magnifications (sic!) in range of 0.1x-0,6x with resolution on ok'ish level. Its not super-resolution beast but its very flexible. Simply approach as close as you can, quickly turn the zoom ring to pre-focus and then let the autofocus do the job (great for flying insects). Its super fast and accurate, also super cheape'o! Once had 18-200 something from tamron and was very dissapointed with it, im very happy with sel55210 (overall, not only regarding close-ups)! -SEL1650 - last but not least (ok maybe least... but still not too bad) is the power zoom on kenko tubes. It goes almost up to 1,5x! unfortunately its too short, working distance is too painfull to use on macro, but its capable of acceptable close-ups. It resolved the red ant eyes! Ok, thats the review part, now time for first questions! Im very happy with my close-ups abilities so far, but still lacking TRUE MACRO lens. I know there is SEL90G... but i got big plans and tight budget on incoming few months. For the price of SONY lens i can get LA-EA2 and 3x Sigma 105, Minolta/Sony A 100mm Macro... which are outstanding lenses... cant see how Sel90 can be any better... I've been able to play with my buddy (he's true macro specialist, got really outstanding photos, but he's Canon user) sigma 105 and sigma 150 2.8 lenses... amazing glasses. 150 is lot more expensive (still fraction of SEL90), but 105 is as good in IQ but lacking a bit in working distance. Around 15 centimeters, wich is still very comfortable for me! So i did extensive research on DXO and few other sites and found couple of options: -Minolta/Sony 100mm on la-ea2 -Canon/Sony Sigma 105 (sony ver lacks OSS due to IBIS, but OSS is great feature - im reluctant to let it go) on la-ea2 or mc-11 (i already own mc-11, but dont get any lenses to test it yet , im afraid of autofocus capabilities). I can get them all second hand for about 250-300 USD. Has any of You used those combinations? I really like OSS and unfortunately wont get it with la-ea2 and sony/minolta (im still considering swaping system to a77mkII for a couple of lenses, but thats later). I also like autofocus - good for flying insects and for casual snapping. I would like to use those lenses as 100 prime, but how good/bad will they perform on mc-11 / la-ea2 and a6000? Or finally... can you recomend other TRUE MACRO options for sony E with appropriate focal lengt (100+)? Edit: If you are interested, i can post some gear photos. Also if you are interested i got tons of similar crappy close-ups like those aboves.
