A Prime For A Time

I have several prime lenses (not as many as I used to have) that I use when the mood takes me, and a lot depends on the weather here, which can be awful at the best of times. My prime lenses currently are:

Tamron 28mm F2.5 (02B)
Tamron 135mm f2.5 (03B)
Tamron 200mm F3.5 CT-200
Tamron 300mm f5.6 TC-300
Canon FL 50mm f1.8
Canon FD 50mm f1.8 S.C
Canon 135mm f3.5 SC 

I also have the following Teleconverters:

Canon Extender 2x -B
Teleplus 2-3x TC

Along with a FotoDioX Pro FD-M43 EXCELL + 1 focal reducer.

I did a quick page using my Tamron 35-70mm zoom, along with the focal reducer, and I was quite impressed by the results, considering how old the Tamron lens is. The trouble was the weather, which couldn't be relied upon even for a few days, let alone a month. So, unlike my "other page", I will attempt to keep the same lens on the camera regardless.

I'm in two minds whether I should use the lenses on my Olympus OM-D E-M1 II, as I can store the lens name in the image Exif data, or attach them to the E-M5 II on a semi-permanent basis, as I won't have to keep swapping them out each time I want to use the E-M1 II and I'll just add the lens info to the filenames using "Bulk Rename Utility".
