These first 3 shots were taken with my Lens Reversing Ring and an old Canon FD 50mm f1.8, yikes a canon lens on a Pentax Camera..... The 4th was taken with my Pentax SMC K-28mm f3.5 reversed.
I'm still figuring out the extreme shallow depth of field thing. I think it will take awhile, though I bet it will help to have no wind!
The rest of this series was with my new Pentax SMC DA 55-300 f4-5.8. I pushed the ISO to 400 and cropped a couple for composition only. I must say that this lens is impressing me more and more every day! Considering it was fairly early in the day and overcast it was able to gather enough light to be quite reasonably sharp.
