I also noted that the thread starter has a 50mm lens which an adapter may be used to reverse the lens. I'll leave it to others to explain the technical details. I use old film lens that I still own if for no other reason than to find a use for something old...... :p

Reversing the lens is for greater than 1:1 macro, and not advised for regular flower photography for most people.

Sorry, my intent was to disclose possibilities and as I said I'll leave it to others to explain the technical aspects. This is not a rebuke and I haven't taken offense. I certainly have never been accused of being normal and will do what most wouldn't advise just to see what would happen.:twisted:

I very strongly discourage reversed AF electronically controlled lenses, particularly since -- unlike 'preset' lenses (from 50 years ago) with mechanical controls -- there is not a convenient way to open diaphram for focus, then quickly and easily stop down the lens for shooting live objects. It might be (pretty inconveniently) workable with totally static subjects.

Thanks Wilt,

As I keep mentioning, I am not very technical. I tend to try and see what happens. When playing with my 50mm's I noticed the diaphrams appeared to be wide open and I've never tried to adjust since I reasoned that it would be useless to try. I focused the old fashion way by moving the camera back and forth. To be clear.......for those reading this post. Follow Wilt's advice........not mine.

We don't use the 50mm enough. Look forward to trying it out this spring on the flowers. Thanks for the input. This was several years ago with the XT.

To be clearer, there can be two definitions of 'reversing'


  1. reverse mounting a single lens using a mount-to-filterthread adapter
  2. reverse mounting two lenses in tandem, one is convensionally mounted to the body and the second is reversed and mounted using a filterthread-to-filterthread adapter, to hold the second lens reverse-mounted on the end of the first lens


In the case of #1, there is no diaphram mechanism operated by the body, so the lens itself must have an aperture selecting ring and also a auto/manual switch (open/closed switch) to permit easier focus wide open and then stepped-down shooting.

In the case of #2, the lens mounted conventionally on the body provides the aperture control and the reversed lens is simply an alternative to using the 'close-up filter'; the second lens' diaphram is pointless.
