That's excellent - your setup worked well and you captured a great moment.

There was some exchange on the list about macro photography and extension a few days ago. Personally I prefer to use stacked lenses for magnification beyond 1X. Here's one I took today, using the 645D, and a 150mm lens stacked with a reversed 75mm. The magnification of this combo is 2X. That's about as much as I can cope with when working handheld. The image is severely cropped, but the motif gives you an idea of the possibilities in the field with this kind of setup. Image only: http://turl.no/kz3 In blog: http://alunfoto.blogspot.no/2012/07/feeding-kiss.html One reason why I prefer stacking over other solutions is that exposure automation keeps working. So you don't have to stop down the lens manually. Another reason is that P-TTL keeps working. Well, sort of; you have to diffuse the flash to avoid overexposure because of the short working distance, but that's okay because you really don't want specular highlights and sharp shadows anyway. And if you're patient, you might actually make AF working. But you have to keep the camera very steady. :-) The knack is to find to lenses that go well together. According to John Shaw (Book; "closeups in nature"), lenses in the normal range are best for reversing, and moderate tele lenses best for attaching to the camera. Personally I recommend using a tele lens with IF because it makes working distance more predictable.
