Newer D-Li90 Battery Question

I seem to remember that the D-Li90 batteries had no date code on them until the K-3 was released, i.e., those that came with the K-7 and K-5 had no date code.

Only in Canada? Pity... Fox story

I've seen that particular fox on Signal Hill. If you approach it while it's standing still and scanning the landscape, it lets you get about 10 feet away from it, but no closer. If you take a step closer, it moves the equivalent distance away without pausing in its task. Not hard to get a frame-filling shot of that fox. However, she was darn lucky to get a picture of a vole trying to look bigger to make the fox back off. The foxes there are so tame because there is a lot of foot traffic on Signal Hill as a result of its status as the spot where Marconi transmitted the first wireless signal across the Atlantic Ocean, and because of the view. Also, some people also feed them, which upsets Parks Canada because it violates National Historic Site regulations. Because of that Parks Canada was trapping foxes on Signal Hill and relocating them.

Pentax KP crashing issues?

A KP purchased from an authorized Canadian dealer will have a 2-year warranty. I suspect that a KP bought through Amazon.ca comes from stock in an American warehouse, like many other goods they sell. A few weeks ago I bought the D-BG6 from Amazon.ca when it was $100 CAD off, but the parcel tracking showed that it shipped from a Amazon fulfillment centre in the US . Consequently the body you bought may not have the 2-year warranty. However, it should still have the 1-year international warranty. Better get it into Sun Camera before one year is up.

This is especially interesting since the number of stores in Canada with in-store Pentax inventory has continued to decline even after the popular K-3 and K-1 were released. There are two camera stores here in St. John's. One of them stopped stopped stocking Pentax by the time the K-5 was released. The other store stopped stocking Pentax by the time the K-3ii was released (although it still carries the Ricoh WG series, formerly Pentax-branded). I would be surprised if there were more than 8 bricks-and-mortar stores in the entire country that stock Pentax DSLRs and lenses.

Amazon delivered the replacement on January 31st. This time they sent the right model. It didn't have an Amazon inventory sticker on it, though.

The sale for $100 off was the first time I had seen Amazon.ca discount the D-BG6 more than $40. However, I don't check Amazon.ca very often, so I could have missed it.

Apparently, the designer of the Limited lenses intended to design lenses with unconventional rendering. This was partly because one of the goals was to design compact, large maximum aperture lenses. Another goal was to make the lenses render images that appear somewhat three-dimensional. See the article at the following link for a detailed discussion.

I think they fully intended to sell the D-BG6 for that sale price, because they listed the correct MSRP. However, I suppose it is a possibility that Amazon made a decision to discount the D-BG6 based on a number of units in their inventory that was erroneous. I have returned the mis-labelled D-BG7 and they say they have shipped a D-BG6. Before the replacement shippped I contacted customer service to warn them of the possibility that other D-BG7s in their warehouse were mis-labelled and that they should confirm that they have a D-BG6 before they pack it into a shipping box. It has been shipped, so we'll see whether the warehouse got the message. It's forecast to arrive on February 4th.

Extremely low temperatures : What to expect and how to counter-balance it?
Posted By pete-tarmigan

While I was growing up in Saskatchewan there were countless January and February days I fervently wished it had been as warm as -25°C. Regardless, in film cameras the mechanical-shutter tripping mechanism would get markedly sluggish (as would the film advance mechanism). I haven't used digital cameras at that temperature, but if exposed for a few hours any lubrication in the mechanical parts of the shutter and mirror mechanisms would get very viscous.

Since the cold will reduce conductivity in the battery, your backup battery should be kept inside your coat to keep it warm for when you need to use it. Putting a cold battery into the camera will result in even fewer shots than the battery that started off in the warm camera.

After your shooting, place the camera in a cold bag before you go inside. The cold air inside the bag will allow the camera to warm up slowly so you won't get condensation.

Disregarding the camera for the moment, if your extremities hurt, they will freeze. Warm them up before they got numb. I made it through the first 23 years of my life without getting frostbite, so it is possible to avoid it.

I recently paid for a Pentax D-BG6 battery grip from Amazon.ca. The item arrived today, but it was a D-BG7. The Ricoh Pentax label on the side of the grip's box showed D-BG7, and the contents consisted of a D-BG7 and a manual for the D-BG7. However, Amazon's inventory control sticker (complete with bar code) on the top of the grip's box showed D-BG6. I wonder if Bezos' relentless push to increase productivity beyond that humanly impossible (except in a police state) is starting to show problems.

The only reason I bought from them is that they were offering the D-BG6 for $100.02 Canadian dollars off the MSRP ($297.99 CAD). None of the local bricks-and-mortar stores sell it for less than MSRP, and I would have to wait at least a month to get it, if Ricoh Canada has stock. If, not I would have to wait 3 months while they get it from Japan. We'll see whether Amazon will get the replacement right. I used their live chat to point out the erroneous Amazon inventory-control sticker and asked them to ensure that the replacement is not an incorrectly labelled D-BG7.

I received my order today -- unfortunately Amazon shipped the wrong item. They sent the D-BG7 instead of the D-BG6, despite the Ricoh label on the box indicating it is the D-BG7, not the D-BG6. Amazon's own label on the box suggests, erroneously, that the item is the D-BG6. The rest of their "D-BG6" stock is probably also D-BG7 too. Probably a result of Jeff Bezos' relentless demand for productivity over and above what is humanly possible.

I think Pentax lost most of their market share in the 1970s when Nikon was the first to provide a complete SLR system for professionals (wide range of lenses, autowinder, motor drive, bulk film backs, flashes, etc.) and used their status as the camera of professionals as a ploy to market to the masses, and when Canon started pouring huge amounts of money into marketing.

When I ordered an upper casting part from US Camera for a Manfrotto 144 tripod, they sent me the corresponding part for a Manfrotto 190 with the "190" stamped in the aluminum part and a sticker on the plastic bag specifying that it was for a 190. The internal diameter in the casting (for the centre column) in these two models is so different that you can tell at a glance that the casting is too small for a 144. Not very impressive. They refunded the cost of the order, but not my cost of shipping it back to them on the far side of the continent.

Evidence-based arguments will change my mind.

Olson is Curator Emeritus at the American Museum of Natural History, Smithsonian Institution. Olson, Alan Feduccia, Evgeny Kurochkin, Per Ericson and Zhonghe Zhou are all highly regarded palaeontolgists that have all personally inspected those same specimens and were all struck by the glaring errors made by Chiappe, Padian, and Prum. Olson is not an outlier among bird palaeontologists or ornithologists -- he's only and outlier if you lump him in with dinosaur palaeontologists who ignore the homology of digits from embryologic evidence (the avian hand is digits II, III, and IV as demonstrated in the Ostrich, the theropod hand is I, II, and III), the anatomy of avian and dinosaur pelvic girdles, the morphology of avian and dinosaur teeth. Theropodists know little about birds -- in the book New Perspectives on the Origin and Early Evolution of Birds. Proceedings of the International Symposium in Honor of John H. Ostrom. Jacques Gauthier and Lawrence F. Gall, Eds. 2001. Peabody Museum of Natural History, Gauthier and de Queiroz claim that tinamous were unknown to Merrem in 1813, whereas the genus Tinamus and the species T. soui was described in 1783 and three additional species of tinamous were named by Gmelin in 1789. In the same book Arnold says that some gull species lose the external hallux entirely, but all gulls have an external hallux, including the two species of kittiwakes in which it is highly reduced. Hopson’s list of birds sampled in his study places Pluvialis in the Glareolidae and contains 15 misspelled names of taxa.

Theropodists fail to include non-dinosaurs as outgroups in their cladistics, and ignore cladistics' failure to identify convergent evolution. Cladistics comes up with the absurd phylogeny in which Hesperornis, loons and grebes are placed into the same clade. The theropod origin of birds also requires flight to have evolved from the ground up, which flies in the face of the laws of physics and the multiple, independent evolution in other animal lineages of flight from the trees down. Evidence-based arguments will change my mind, not the sensationalist marketing of decomposed collagen as proto-feathers, and other fiction based on flawed techniques that Chiappe, Padian and Prum have been spewing, or the abuse of the peer-review process of scientific publication that Henry Gee committed as an editor of Nature. They are rather akin to those Lamarkians and Creationists who for decades have denied evolution by natural selection, and who history will show how uninformed and fraudulent they are. They are worse in that these Hennig Youth suppress dissent by shouting down opposition and by biasing the peer review process of publication of scientific research by selecting like-minded reviewers, e.g., barring avian palaeontologists or ornithologists from refereeing submitted manuscripts.

Unfortunately, Micropator lacks salient theropod dinosaur features that are necessary for fully upright posture, i.e., the pelvis and the hip and shoulder joints are very unlike those of theropods but very similar to basal archosaurs. Microraptor can only be a legitimate, basal bird.
(Czerkas, S. A., and A. Feduccia. 2014. Jurassic archosaur is a non-dinosaurian bird. Journal of Ornithology 155:581-851.)

To quote Storrs Olson again:
If Caudipteryx is not a feathered dinosaur, what about all those other supposed feathered dinosaurs from China that the public has recently been bombarded with? To be succinct, there are none. The whole story is essentially a hoax. Numerous specimens of various theropod dinosaurs from the Liaoning Lake deposits are preserved with associated carbonized filaments often positioned so as to appear to be integumentary structures. None of this ‘‘dinofuzz’’ exhibits the structure of a pennaceous feather. Furthermore, there reportedly are in the same deposits various other organisms, unrelated to birds or theropods, that sport those same filaments. If so, the information has been suppressed.

The BADM [Birds as Dinosaurs Movement] has been putting imaginary feathers on dinosaurs for more than 20 years (Battaglia 1979), but real fossils with feathers were crucial to making the bird–dinosaur connection. So when the filament adorned dinosaur fossils turned up in China there was little hesitation about hyping them as feathered dinosaurs. Not surprisingly, an entirely conjectural origin of feathers from filaments was hastily supplied (Prum 1999). Feathers are preserved in the fossil record in a unique manner that is easily recognizable with scanning electron microscopy (Davis and Briggs 1995), but that was not done for the Chinese fossils before they were so enthusiastically presented as feathered dinosaurs.
...
It is clear that raising any question whatever about the theropod origin of birds is unacceptable to those in the BADM. Prum (2002:5) ironically refers to the ‘‘unrelenting criticism’’ of the theory, when in reality the voices of criticism have for the most part been drowned out by the incessant
petarade of propaganda from the BADM. Prum’s own essay is little more than naked proselytizing, designed to cajole the heathen onto the path of enlightenment. Like a harassed politician, Padian (p. 485) blames the media for helping to keep controversy alive and bemoans the fact that the BADM agenda is diminished by what he regards as an inappropriate attempt on the part of reporters to achieve balance and fairness.

It is often emphasized in publications of the BADM that its opponents are unscientific. Padian has maintained that the truth has been revealed and that contrary views should be suppressed. Prum (2002:13) exhorts ornithologists to ‘‘abandon debate on the theropod origin of birds.’’ In my view, that is the most unscientific posture of all. What are these people afraid of? If the evidence for a theropod origin of birds is so overwhelming, why can it not stand on its own merits without active suppression of contrary views, without proselytizing the noncombatants, and without a vigorous propaganda campaign in the popular press?

Just look for publications on the topic by Storrs Olson, or by Alan Feduccia of University of North Carolina. Olson's publications have the added benefit of bits of humour inserted here and there. Some of those publications are technical (e.g., homology of the phalanges), but their reviews of scholarly books (published in scholarly journals) don't require as much technical background.

What the heck? I don't know what species of warbler that is. I don't have my warbler ID guides with me at the moment, but, by process of elimination, it seems to be a hybrid of some combination.

Regardless, it's a nice capture.

Regarding yellowlegs, they are fun to watch because their prey items are large enough that you actually identify the family or order that the prey belongs to.

Addendum:
The warbler has the right facial pattern, flank streaking, back pattern, and wing bars for Blackburnian Warbler. However, the yellow (seen in first-winter females) extends much farther onto the belly and is exceptionally brighter than most Blackburnians.
