Todays post contrasts two very different lenses. A 31mm fully modern lens and a 200mm fuuly manual vintage lens.
Camera: Pentax K1 (Click for reviews)
Lens: SMC Pentax 200mm f/2.5 K-series (Click for reviews)
ISO 200 f/8? (EXIF does not include f/stop) 1/6400th Tripod mounted.
This was a test shot to frame and get focus with this manual focus lens. To me this has an almost 3 dimentional quality. The out of focus areas render very smoothly.
ISO 800 F/8? (just my mest memory) 1/8000th Tripod Mounted
This family, out on a Sunday afternoon walk, seem separated from the backgroung and foreground in a way I like very much. With my 54 year old eyes it is a bit of a challenge getting the focus.
Lens: SMC Pentax-FA 31mm f/1.8 AL Limited (click for review)
ISO 800 f/9 1/1000th tripod mounted.
Compare the above image at f/9 versus the one below at f/2.5
ISO 800 f/2.5 1/8000th Tripod mounted.
I was surprised that at f/2.5 most of the tree trunk seems in focus. You can see a diference between the two apertures. At f/9 the clouds are still pretty sharp. But opened up to f/2.5 the blur is gentle and still lets you see what is in the background pretty nicely.
It was a fun Sunday afternoon comparing these two lenses. I like the looks that each lens gives very much. I can't wait to try out the 31 Limited on a family portrait!
