Blue flag again, probably taken at a smaller aperture because the background is not as well bokehed. I wanted an excuse to post the second image which shows one of the blue flag patches that bloom in the Spring one place where we walk. At a distance, they just look like a bluish blush across the tips of the foreground vegetation. Difficult to walk over to that patch -, lots of tangled, trip-you-quick growth between the trail and the irises.

Among garden enthusiasts, dahlias are noted for the spendid bokeh they produce.

NOTE: EXIF information is incorrect regarding lens identification. This lens actually is the Phoenix 100mm f 3.5, said to be manufactured by Hoya.

The Phoenix 100mm f3.5, Cosina, and Pentax are widely understood to be the same lens.
And the non-Pentax ones were available in manual focus and autofocus.

I have the Pentax one... and the matching 1:1 closeup filter... it is a great little lens, though it is mechanically not as well made as my FA50 Macro...

But I don't have nearly as many convenient dahlias for giving it a workout

That is very interesting to me. I had some curiosity along this line when I learned recently that the Phoenix was made by Hoya, and I recalled the Hoya-Pentax connections. I bought this lens way back when I first entered the digital age by acquiring a new K-10, and it was quite inexpensive, so cheap in fact that I have never given it much respect. I have usually used the Tokina-ATX 90mm f 2.5, the Pentax-D FA 50mm f 2.8, or the Kiron 105mm f 2.8, and always thought I should acquire the Pentax 100mm but never did. Trying out the Phoenix was an eye opener for me, and I find it to be quite good even without the closeup filter. Generally, 1:2 macro is quite enough for my flower photography. Nowadays, I also have the Zeiss 100mm f 2.0 macro 1:2 which pretty much trumps the field even though it is large and heavy. It is also MF, but I usually use MF for macro any way.

I love the dahlias for flower photography, and select the ones for my garden each year with next year's photography in mind, trying to pick the most photogenic models.
