Here's a few photos I took with a Pentax K-5IIs crop DSLR the morning of 8/5/18 in Boca Raton. All shots ISO 400. Lenses used Pentax K18/3.5 K28/3.5 K120/2.8 Tamron SP LD 180mm/2.5. Manual Mode and green button exposure metering was used on all K lenses, and the Tamron lens was used on program mode. All files RAW DNG and only minor exposure adjustments and resizing for web were done in PS. While these 40+ year old K lenses may not be good enough for a state of the art K-1 full frame sensor, they seem more than adequate for a quality aps-c crop sensor DSLR.
