Pentax 67 smc 150mm 2.8 on a7ii with macro tubes

[jamaeolus]

I am really enamored of the 67 lenses. These were taken in late afternoon sunlight with the 2 larger macro tubes. This website

http://antiquecameras.net/pentax6x7lenses.html

rates the IQ of this lens as a "B". I am saving up to get the 400 ED IF which they rate as "stunning". How much sharper can they actually be? Anyway some slight adjustments to brightness as I underexposed these, also minor tweak to contrast. Scaled image then 100% crop.

The orchid was taken indoor under artificial light.

Nice idea, wonderful tulips, but sadly enough very inconsistent lighting, some are way too dark - did you try to adjust in PP?

On a couple I did some minor tweaks but didn't on most of this. I Need to pay more attention to the histogram!
