Hm, I see now

I surely found Kavinia there but these photos are clearly not. But I cannot find shots of Kavinia. A mystery to me but thanks for correction.
I do not know which species of poroid fungus this is too. No notes about such one.

keep your Panasonic DMC-FX10, since it’s quite capable of plenty compelling macro on its own:


lightweight and cheap

without knowing what you’re currently shooting with, these are my suggestions:

option one: http://campl.us/posts/iPhone-4S-Extreme-Closeups

option two: http://en.wikipedia.org/wiki/Close-up_filter (some P&Ss have the threading to accept these)

option three: Pentax WG-2 (+/- GPS). has a “microscope mode” which allows for a minimum focus distance of 1cm with LED ring lighting.

option three and a half: any number of other mid- to high-range P&Ss on the market which take anywhere from good to superb macro images of varying ranges of magnification (ie: Canon Powershot G9, Nikon Coolpix P90, etc. see http://www.flickr.com/search/?w=11248435@N04&q=macro for examples. then there’s the Ecuador section of MycoKey, all shot with a Nikon Coolpix 995 and Coolpix 8700). 4/3rds cameras have also come down in price a ton since their inaugural days. Buy a used Olympus PEN or Lumix G series body, mount the ~$200 Zuiko 35mm f/3.5 at the end of it (4/3 to m4/3 adapter required), and you have a very, very sharp 1:1 setup for under $500.

but priorities are different.
I just have a compact camera right now. When I did analog photographing I had a good Nikon with titanium coating that weighed a lot. That’s why I refuse to carry a heavy weight with me again. But I have to admit that I am not really content with the pics anymore.

you’ll spend more on groceries in 48 hours than it would cost to modify whatever equipment you already have to be able to shoot at magnifications greater than this. i can help you. start with extension tubes, which you can make yourself (google DIY extension tube or similar queries) if you can’t afford a set, and a set will only run you $100, more or less.

it’s all a matter of money :)

you would start shooting these close-up. not just because it would make these already precious observations of never-observed taxa considerably more valuable, but because it would allow me to actually determine which of these are good candidates for this list: http://mushroomobserver.org/species_list/show_species_list/230. in a good many of your resupinate obs, the hymenium is too far away or blurry to make out.

I seem to remember making a similar appeal before. whatever could possibly persuade you to more thoroughly document your obvious penchant (and talent) for corticioid and resupinate fungi?
