I see it now, this from Ricoh's website re K-1:

SR II in-body shake reduction mechanism The world’s first five-axis, five-shutter-step camera shake compensation*
The PENTAX-original sensor-shift-type shake reduction mechanism has been upgraded to provide optimum compensation for all lenses used in handheld shooting.

Compatible with panning shots
When taking a panning shot, this mechanism efficiently controls the SR unit to detect only the direction of the camera’s movement, while compensating for all other affecting vectors. Because of this, the K-1 captures beautiful, high-resolution images both in normal shooting and panning photography, without requiring any switching operation.

Mike, thanks again. I looked at Tamron's website and see the model variations; the "A001" is only model that has the K-mount as you indicated. I am not averse to buying used, done it before w/good luck- however, I think my chances of finding a seller who is local to me so that I can see the lens before buying is slim, this is Pentax stuff not Nikon or Canon. I'm leaning strongly to this lens, price is decent and I can sell my 60-250mm by pricing it accordingly and of course disclose the AF motor issue. Lens is pristine but after having once had the motor replaced then that one die, well, I'm just reluctant to put another $300 or so into the lens - if it were truly a FF design I might well do so.

Thanks. That last (unprocessed) image was the beginning of a pano shot; here's what the pano came out looking like, plus another shot that was taken 30 minutes before sunrise. I just need 'farmers pond' to get filled up with a bit more water or move my camera position so I capture the scene w/o the mud shoreline in foreground.

Thank you. The place where that was shot is called 'Farmers Pond' by the locals. This pic was taken in same location, but a much tighter shot, it was taken in March a couple of years ago - compare the two, look at the three trees- they are in both shots;notice how much water is in that area after winter is about over. That pano is good but the mud/low water level is not so pretty....I need more water, or maybe a different camera location for the shot.

Understood, but still....the aspect ratio of the viewfinder which we look through has an effect on our initial composition, camera position, etc. Be ideal to be able to work with something other than 3:2 ratio in the field.

The first signs of an official decline occurred in 1912 with the printing of the last Bodie newspaper, The Bodie Miner. In a 1913 book titled California Tourist Guide and Handbook: Authentic Description of Routes of Travel and Points of Interest in California, the authors, Wells and Aubrey Drury, described Bodie as a "mining town, which is the center of a large mineral region". They referred to two hotels and a railroad operating there.[28] In 1913, the Standard Consolidated Mine closed. Mining profits in 1914 were at a low of $6,821.[15] James S. Cain was buying up everything from the town lots to the mining claims, and reopened the Standard mill to former employees, which resulted in an over $100,000 profit in 1915.[7] However, this financial growth was not in time to stop the town's decline. In 1917, the Bodie Railway was abandoned and its iron tracks were scrapped.

The last mine closed in 1942, due to War Production Board order L-208, shutting down all nonessential gold mines in the United States during World War II. Mining never resumed after the war.[7][8][29]

Bodie was first described as a "ghost town" in 1915.[30] In a time when auto travel was on a rise, many travelers reached Bodie via automobiles. The San Francisco Chronicle published an article in 1919 to dispute the "ghost town" label.[31] By 1920, Bodie's population was recorded by the US Federal Census at a total of 120 people. Despite the decline and a severe fire in the business district in 1932, Bodie had permanent residents through most of the 20th century. A post office operated at Bodie from 1877 to 1942

One of the last photo trips I took while I still owned my K3-II was winter of 2017 - a stellar winter in California, tons of snow. Out at dawn one morning to capture sunrise at Mt. Tom in the Eastern Sierra's and I spotted this bare tree reflected in a drainage ditch on a ranch in Round Valley, this was about 20 feet away from where I had my tripod setup a half hour earlier to capture first light on the mountain. As as I was packing up my gear heading to my car I came across this spot. Sometimes it pays to look in all directions, up, down and wherever!

Thanks, some good input here, particularly regarding the effects PS can have on color rendition- I was only thinking in terms of resolution, image sharpness - so this is good info! I've not done much with PS shooting so some experimentation is in order.

Convict Lake, located just West across Hwy 395 and the Mammoth/Yosemite airport - Eastern Sierra Nevada Mountains. Lake elevation 7,850 Ft. (2,393m) above sea level. 5 raw images shot in portrait mode and stitched in LR 6; this shot takes in about a 140 degree field of view shot at 9am. Too bad no dramatic weather happening, just a beautiful morning!

Would a DA* 50-135mm f2.8 work fine for motorsports?

I'm not much of an 'action shooter' but I did take my old K3-II out to the BMW autocross a couple of times. I primarily used 50-135mm lens (SDM driven AF). As others have mentioned, and you probably already know - camera handling (e.g. panning, etc.) is critical to really getting good results. I found the 50-135's auto-focus did not do a very good job, and the cars I was shooting were not moving all that quickly, tho they were reasonably close as I shot from within the course. I ended up with best results by pre-focusing and panning, following the car into that focused 'zone'. Again, only went to couple of events but I spent enough time fiddling with the AF onsite and reviewing results at home to realize it did not really work very well for me. The lens itself is nice to handle and has very good IQ - no issues on those points. One more thing to note, I was shooting at pretty modest (low) shutter speeds in order to pan and get 'reasonable' background blur on many shots....that did not make the job of keeping the car in sharp focus any easier!

...first two images are w/50-135, other's with 60-250mm.

Good Luck/Bill

The lake, known to the Paiute as Wit-sa-nap[1], was renamed by white settlers after an incident on September 23, 1871, where a group of convicts escaped from prison in Carson City. A posse, from Benton, led by Deputy Sheriff George Hightower, encountered the convicts near the head of what is now Convict Creek. Posse member Robert Morrison, a Benton merchant and Wells Fargo Agent, was killed in the encounter, and Mount Morrison was named after him. It has frequently been noted on lists of unusual place names.

and unfortunately.....In February 1990, Convict Lake was the site of a major drowning. Twelve teenagers and two counselors from a nearby camp were on a holiday outing at Convict Lake. At least four teenagers and both adults fell through the thin ice and into the water. By the time the first rescuer arrived on the scene, only one teenager had been able to pull himself out of the water, but the other teenagers were no longer in sight, having apparently already drowned.[5] In all, three teenagers from Camp O'Neal, an institution for juvenile delinquents located near Whitmore Hot Springs,[6] and four would-be rescuers drowned in the freezing water. Another youth and a volunteer fire chief were rescued. Shortly before their deaths, the youths were warned that the ice was too thin to support their weight but failed to heed the warning.[7]

K-1 and simulating effect of long exposure
Posted By wgosma
Replies: 16

I've seen some 'interval composite' images that were created from a series of exposures that were each in the 2-4 second range as you've mentioned, pretty impressive. For mid-day shooting combining a polarizer, 3 or 6 stop ND filter with the 'interval composite' method looks like a potentially nice tool to have/use.

As far as the shutter count goes, well....to me it's like looking at the odometer on the car after a long roadtrip - relatively rapid increase in mileage, but then again....what value is a car if one does not take it out and drive it? Ditto for a camera, and every other gadget, tool or material belonging - nothing lasts forever. By the time I might get to registering 300K clicks on the K-1, well....we'll I expect digital photography may well have undergone some significant changes, time for some new gear ;)
Thanks/Bill

Agreed, this is an issue. However, with a 300K MTBF on the K-1's shutter, unless one becomes a major interval shooting junkie I think we're good. I think I'd tire of looking a pic's with silky smooth water and blurred clouds long before the odometer gets anywhere near the really high mileage mark ;)

Thanks/Bill

Definite possibilities here....I think I'll decide on my ND grads and holder, then think a while on solid ND filters - I've used the Haida ND's in the past with my K3-II and they're darn nice filters (near zero color cast, bit warm which is OK) and reasonably priced.

This is another tool that resides in the K-1's toolbox, some interesting & creative pic's could be had between using the interval and multi-exposure composite shooting modes.

DA* 60-250 mod for FF

I completed this modification today. See photos showing the tube/baffle piece removed from the lens, pics taken just after completion of enlarging the 'flange' area opening.

Now this metalwork is not going to be winning any awards from the tool and die makers in the audience, but it works for me. I used flat and small rounded metal hand files for the work and cradled the tube in the partially open jaws of my bench-mounted vice, holding the tube down on the open jaws with one hand while I filed away using the other hand. This tube is 0.030" thick aluminum, it's pretty soft material in my book; the prior comments in this thread about the material being 'quite hard' seem a bit odd to me.

I used some painters tape to protect the inside of the tube/baffle from the metal filings/particles; cleanup was pretty easy with some compressed air and an old toothbrush. Now all I need to do is blackout the exposed aluminum surface, reassemble and shoot some test pics.

Any questions, let me know.

Thanks/Bill
