Couple with the Tamron 28-75 some with CPL

I intended to pack the Tamron 17-50 to take an off project shot with it to post here. Folks were asking about that lens at the time. However, the similar looking Tamron 28-75 actually got packed so I took the shot with it anyway.

So wide open is 28mm and f/2.8 (not necessary but on purpose) and I would have liked the composition better at 17mm with the wider zoom.

The flower shots are tests of a CPL (67mm B+W KSM) with the 28-75 set at the 60mm hash (much better focal length with this lens and almost macro with its 30cm min focus distance). This registers as 55mm by the K3 FWIW.

Tamron 28-75 on K3 at 28mm f/2.8 no CPL

With B+W CPL set to 60mm f/7.1 0 bias (K3 says it is 55mm in the exif)

Same

Same

f/5.6 still CPL

Cheers.
