You get the same results from an *istD too. Personally I like the ornamental plum/ winter cherry because it stands out so against the huge trunk behind it.

I presume I don't need any of those above v1.50 as I can't afford the mortgage for those two lenses anyway.

All in blue? Did you inadvertently change the white balance to Tungsten? Welcome to the Forum.

Nice to see unusual kit demonstrated.

Lennybloke and Barrie commented above about the PLM with a 1.4TC. I have to confess that combination had never
occurred to me so I took it out on the K3ii this afternoon set at ISO800. The results were very favourable..

at 77mm to give an idea of the range ....



and the same scene at 420mm and f10. Very moderate PP just to brighten it up and slightly cropped in to fill the frame.



This is a bit closer with deliberate bokeh, also at 420mm and f9.5 (it's a spent and dead echinops bloom).



There were several other shots too that were equally pleasing but I think these give an idea of
what a PLM and 1.4TC can do, especially since conditions were dull and miserable.

Your early starts do tend to reap rewards. My brain simply won't function in the morning when the hour only has one digit.

I think you got yourself an excellent lens there ! One of my favourites is the Pentax-F 35-105. That too vignettes slightly at the wide end on the K1.

A shoulder stock would still allow the front of the lens to move in quite a wide arc (relatively speaking) in several planes. I am getting more shaky as the years go by and I have been encouraged by the high ISO results from other people to abandon the traditional "keep the ISO low to avoid grain/noise" mantra. It's astonishing how ingrained that one can be! I am now regularly using 1600, 3200 and even 6400 having realized the cameras (K3ii and K1) will accommodate it. Movement blur is killed outright. Clearly there are limits to this depending on your style, but I would certainly experiment with higher ISOs before shelling out hard cash.

Pity about the modern brick thing on the right of the 2nd image (not your fault!). That aside, it almost looks like a half plate contact print from years ago.

Definitely the crater. Painting skill aside, it provides a tangible focal point for the eye, which can then explore the remainder. (When further craters are discovered )
