Originally posted by clawhammer FWIW, I've heard of people taking the glass out of a teleconverter and using that for an extension tube. I've been tempted to try that with my cheapo 2x tc, but haven't had the guts (I don't like to reduce things from a known-working state to a possibly-working state) to try it yet.
Trust me, It doesn't work
It just isn't possible to get shots like this like this.
Oh, that is how I got that shot, using a 35mm f2.0 Super Tak
Xcom, I know where there are some NEW Genuine Pentax Lens Reverse adapters. Both 49, and 52mm. They'll allow you to get right up to the plant. However the DOF will be extremely shallow, making it almost impossible to focus, without a Macro Slider.
With the lens soo close to the plant you pretty much also need some Off Camera lighting source. Often even just to focus
The camera it's self causes a pretty dark shadow at times.
