Nice you found us Amol, given what you have in your kit. All those manual focus lenses would be lonely without the sort of friends you'll find on this thread... that you've already begun to meet in fact. We've had a few friends in and around Seattle over the years though the two most active in the past have wandered a bit. John showed up recently with shots from his trip to Slovenia, I believe. He lives in West Seattle. Ani lives east of Seattle in the mountains with her husband, horses and Yorkshire terrier. But alas, at the moment you'll have to show us what is happening in the Seattle area. Enjoy your lenses and your new D500. See you on the thread.
Love it Ray... so reminiscent of my childhood and the trips we made to northern Minnesota, driving through scenes like this to my grandparents farm. Great sky... like one finds in this part of the country in summertime. Thanks for this one...

Curtis - wow -that camera/lens combo seems great for flower photos - very impressed with the rendition. I shall have to look into a 135 QC!!
As I mentioned, we had many conversations about that lens back in the day. I even put together this comparison between the 135 f/2 AI-s, 135 f/2.8 AI, 135 f/2.8 K AI and the 135 f/2.8 Q.C. AI... I love the big heavy f/2 but the Q.C. and K. are a touch lighter and just as easy to handle with still excellent performance. I still own all four, but then everyone knows I don't know how to sell a lens UNLESS I've already bought a replacement in better condition...
Thanks for your likes and comments on my previous image post! Here is another set from the west coast of Vancouver Island. The trait these have in common is that each of them proved to be conducive to a square format. The first and third were shot with the 24 f/2.8 NC and the second was shot with the 16 f/3.5 Ai.
Late afternoon - 5:30 pm as we head towards midwinter. It was lovely and warm as we'd had a "berg" wind and midday temperatures of 30*C (A berg wind (from Afrikaans berg "mountain" + wind "wind", i.e. a mountain wind) is the South African name for a katabatic wind:a hot, dry wind blowing off the interior plateau of South Africa, roughly at right angles to the coast. Berg winds are mainly an autumn-winter-spring phenomenon.)

Did you know that when the H2S is above a certain concentration you can no longer smell it? That's when it becomes lethal....I remember that I did get a bit worried when my chemistry professor told us about that in the lab. We used very low concentrations of course. But it was still a quite scary gas to work with...
It is a very dangerous chemical and the lethal dose for adults is quite low 500-1000 ppm.
The paralysing effect on the olfactory perception you mention is > 150 ppm. But until that threshold is reached you will smell it profoundly.
I started my caree working with sulfur chemicals and am very glad that is over.

Take care!

I vaguely remember my qualitative analysis professor saying that as the dangerous level is reached, it may start to smell sweet rather than the typical "rotten egg" smell. He said if that happened, get out of the lab and into fresh air immediately. But that was so many decades ago that I can't recall the details.
Eike, perhaps you could confirm or refute the validity of that observation.
Are we going to need a course in organic chemistry to participate in this conversation now?
I love how this conversation wanders all over the place, from the sublime to the ridiculous, to the sacred and mundane. We are blessed to have some talented, well educated folks playing with us, so we get to learn as well as play...
Thanks Kristian, Eike and Ken for keeping us current.
AWESOME shot Ken. How much in the moment can we be? Just like this... you see the light and because the camera is nearby you take the photo. Really like this shot.
For some reason I'm drawn to repost an image from a year and a half ago taken while walking on North Beach near the end of Sir Francis Drake Boulevard which passes within two blocks of my home in San Anselmo. It is a great place for a stroll and occasionally Sue and I will make a visit. This was shot with the 55 f/1.2 S.C. AI which is perhaps my favorite walk around lens... it better be or how else would I justify owning THREE of them...
