More photos of the hummers... the bugs are so bad, I can only stay out for so long, and almost missed my light, which led to lighting maybe 60 sidelight, which in turn led to some very good contrast in the feather detail. Most images were ruined because he turned his head the wrong way or was in complete shadow, but the ones that came out look good to me.

On the second one, there is actually feather detail in the wing. I guess 1/4000s is what you need to freeze a hummingbird.

K-3 - DA*200 plus HD DA 1.4 TC
ƒ5.6, 1/4000s, ISOs 640, 1250, 1600 (TAV mode)

You know I'm happy with the 36 MP sensor It is as I thought it should be, Bravo Ricoh ! More than that I'm happy to see folks are happy thus far (and I expect in the future for the most part) with the K1, it looks as though it has all the potential to be Still swinging above it's weight class and I'm thrilled. I must also say that I am very satisfied with my crop sensor camera although there are no doubt many areas where the K1 should and could exceed out current expectations. Anywho I could go on & on but that dog will most likely be tested (da) and tested again..... I will be waiting to see how the K1 thread progresses and following with ears tuned (and eyes). Happy Memorial Day ! Be safe and enjoy you equipment after all it could be Canon or Nikon and you wouldn't even have to deal with some small town guy prejudiced by some Big City Player when you know dollar for dollar you whooped his but long ago....................

Up till today I have been rather fudging on how I did my lens calibration and I have looked at the Lensalign and spydercal types of calibration accessories but they seem to start at $100 for some cheap plastic so I went out to my shop and decided to come up with my own design. I had an old wooden meter stick, some electrical tape for the sight and some scrap walnut and in little over an hour this is what I came up with. I installed an insert in the base to allow me to attach it directly to a tripod.
I made it larger and it has larger increments than the over the counter types and I think it will actually be better for the longer lenses.
After a number of test shots I found I only needed +1 adjustment on the camera to have the depth of field centred on the focus point. I included two shots taken with the FA*600 the first at 50ft and the second at 20ft. It works just awesome and expect it will eventually become a family heirloom
Were these shots wide open at f4?

fireweed.

While I don't always use 300 mm for a flower photo here is a K-1 at work ISO 800 f/4.5 at 1/640. A pretty scraggly fireweed because as the name implies
It likes the bright sunlight of a recently burned over area, and casts off seed with parachutes like dandelions that will blow for miles in open areas, but this one was growing on a road's edge in a neaer
jungle. IT's full frame.... uncropped. I was sort of taken by the back ground.

a couple of ships at 300mm

while I was shooting fire weed, I also grabbed a couple of shots at ships at anchor.. both taken across the Columbia river with a 300 and a K1 The ships who where near each other
appear to be riding anchor awaiting the end of the holiday weekend.

re: In theory the resolution of the cropped image is akin to what a K5 would deliver. The 150~450 on a K3 should have somewhat more resolution because the K3 has greater pixel density than the K1.

Gray Jay / camp robber

Even a younger looking camp robber can't stand to leave the feeder without mouth full.....
k3+f*300-4.5+DA1.4x@f/7-1/500 and ISO 6400.

I just keep wondering why my good friends here haven't drifted to higher ISO's. There was certainly plenty of reason
to do so in various out of production digital Pentaxes, but with the k3/k-1 those reasons seem to have faded.
This, for example is a photo that would have been extremely difficult to get at traditional film level ISO levels.

They can get rid of the noise in higher ISO photos, but you're still losing dynamic range.

I completely agree with your calculations. The real test is on the street, and i'm missing a component to test with. I would be inclined to put the 150-450 on the K-1 and set it against
a k-3 with a 300 + a 1.4x TC for special occasions.. My expectation would be to find very similar performance, and if i did, it would be very hard to justify keeping the K-3 around.

Presently one of the most happy pieces of glass I have is the F*300 f/4.5 matched with the DA1.4xTC. I hard set the ISO to 6400, and it becomes the sudden, oh my gosh point and shoot.

I have lots of heavier iron, but heavier is the operative word Exclusive of some mirror glass, I think I presently own 3 of the 5 heaviest pieces of glass that Pentax ever made. None provides
the record response time at a surprise sighting of a potentially moving target.

Right now the hardware item that would make me reach for the plastic faster than anything would be a FA class TC that fully supports auto focus. While I haven't tried it yet, I completely assume
that the DA 1.4x TC currently in production means what it says when it's labeled DA........

Yes Gary F4 -The shot taken at roughly 20 feet (bit less) looks to have have a depth of field of about 2 centimetres

I was out yesterday and found my yellow headed blackbird again, he was singing his heart out and I'm pretty sure he was singing "Some Where My Love" There was also a group of duckings cruising around I'm not certain but I think they were Ringnecks.

I usually start at 400 and shoot as high as 3200 sometimes.

Red winged blackbird

Here I captured a male redwing blackbird,

Once again with the K3-300-f4.5_DA1.4x @f10-1/800 @ISO 800

which followed by a Juvenile Redwing blackbird (or possibly a female---they are marked the same but this one was fairly small making me think Juvenile...

K1 w/ FA*300 +2x-L TC @ f8 -1/320 @ISO 800 (heavily cropped)
