Chris, the weather conditions were more favorable for me that morning. But your images are excellent regardless! That was my second time shooting and even after the last time 2 weeks ago, I still would consider going back next year. It was a lot of fun, for sure...
Many thanks, Joshua. I've been up there more than a dozen times, and it never gets old. My problem is that I'm usually limited to 1-2 day trips these days, so if the weather doesn't cooperate during that very short time span, then it can become an issue. That said, I'm grateful that I managed to take pictures of the eagles this year, after last year's cancellation of the boat trip.

Very nice, Ross! Did you use focus bracketing for this? I had been hoping for focus bracketing for a long time but haven't really used it much since I got the A7RV.
Jaw-dropping image, Barry! That's what I would call a picture-perfect condition for a capture down to the sun placement, sky colors, reflection on the rocks, and waves.

Thank you Joshua for the very kind compliment, its most appreciated my friend
I just do the easy bit!...I take the images and process them like everybody else here does - Then my lovely wife Alison gets to work on them and tells me do it again! (Normally because I have screwed up the colour)
Thx again Barry
PS. Jigokudani looks cold!

They say I am the hardest man in the west.
I subsist through frigid fingers of winter, rejuvenate by the tender touch of spring, and proliferate in the oppressive heat of summer; I have yet to figure out fall.
Where most merely exist, some maybe even thrive, I conquer.
My name is Dan, Dan de Lion. And I am here to take over your land.

Thanks, Douglas! The badland hills were distant enough that I had plenty of depth of field without needing focus stacking.
This one is the Zeiss Contax (CY) 100mm f3.5 Sonnar, a very faithful representation of the traditional landmark lens design - the Sonnar. I kind of dismissed it for landscapes but these look better than I recall. Low contrast lenses do well in the mountains. But it's disconcerting when you see your tastes change, you might agree.
'..the Distagon 2.8/21 for the Contax SLR, a relatively complex lens with 15 elements in 13 groups. However, it had no aspherical surfaces. Its performance, particularly the perfect correction of lateral chromatic aberration, was achieved solely by the combination of very special (and expensive) high-index glass types with glass types displaying extremely high anomalous
partial dispersion.'
Not much is said about high refraction glass (HRI) these days, for whatever reason. But a lot of the very fine turn-of-the-century lenses used it a lot - Leica's APOs included. The above quote from Dr Nasse of Zeiss suggests HRI is half of the story for these lenses, along with the now ubiquitous APD (or LD) glass types.
Borosilicate Crown glass is used as a base price and other materials are priced as a multiple of this. Common glasses have "cost factors" of 1-5x. Low-dispersion glasses are closer to 10x, and anomalous partial dispersion or high index materials reach as high as 30x. These are Zanskar and Yarlung, Tibet.
