Fruit Fly?
by Photon
I have cropped this one to approx 1/4 of the area camera produced image. Taken with the Pentax 100 mm Macro lens, at closest focus but I still can't get as close as I want to! A lens giving me a 2:1 or 3:1 ratio would be very highly desirable. This fly was sunbathing on a strawberry plant leaf.

Have you tried extension tubes or a reversed 50mm lens on the front of your macro lens? That gives greater magnification - but also means you are physically much closer to the subject which might make your subject flee!

I used extension tubes a lot, back in the early 1970's before macro lenses, with my old 'Exakta' camera, the problem was that the intensity of the light ('Lux', I think!) falls off inversely proportionally to the square of the distance of the lens pole from the film plane, these days the sensor plane, which often resulted in exposures in the order of ten minutes, this was O.K. for woodland fungi, since they don't move but no good for insects. I cannot justify the cost of an additional 50mm lens but I did try reversing my 35mm onto the 100mm whilst still life shooting on the dinning table (Oral-B floss container pots make lovely test targets). I experienced difficulties, I can't remember what now! In, addition, I wasn't happy with all that cantilevered weight on the camera bayonet mount. I have also considered contriving an adaptor lead to allow reversal of the 100mm lens whilst maintaining electrical contact between the lens contacts and the camera contacts but this would entail butchering the fore and aft elements of an expensive extension tube set. I haven't thought this one through completely yet and I don't have the necessary machinery in my garden shed. Nobody makes plastic versions, not even on e-bay, which would be ideal for insulation considerations. Furthermore, reversing the lens puts the rear element at risk of damage! Thank you very much for the suggestions and I enjoyed your ambiguous use of the word 'flee'. Perhaps I should have put all this diatribe into one of those things called a 'Thread' of the forum, which I have rarely used.
