Tamron SF AF 90mm f/2.8 Di Macro.

Now renamed Guarechea Frances Dyer, this is an old hybrid registered in 1955. It is a hybrid of Guarianthe (Cattleya) bowringiana and Prosthechea (Epidendrum) fragrans.

This is Phalaenopsis Micro Nova crossed with Phalaenopsis philippinensis, a miniature Phalaenopsis. I've included this photo and the previous to illustrate the results of "focus stacking." As those who are interested in macro photography know, it is difficult to get good bokeh and good depth of field in the same picture. Often one has to be traded off for the other, i.e., if a larger aperture is used to blur the background, then the depth of field will be very shallow and the front or back of the subject will be out of focus. This does not always matter, but if it does the problem can be solved using "focus stacking." This involves taking a number of the same picture (using a tripod), but in each picture focusing on a different part of the subject, i.e., front, middle, back, and then "stacking" the pictures using suitable software so that the result is a picture in perfect focus from front to back. This particular photo was stacked using a freeware program called CombineZM and is a "stack" of three photos. This software can be downloaded at www.digitalgrin.com/showthread.php?t=61316 and there are detailed instructions for using the software at that site as well.
