Should have been clearer on that one, Sony full-frame outsells ALL of Pentax

Both Sony and Nikon make (more catered to) entry level full-frame that isn't priced much higher than Pentax. Which is one reason that Sony full-frame outsells all of Pentax

Good to see SRS taking the extra effort.

On the flip side... Not specifically that given "switch assembly", but... This is the third exact copy of this lens that I've seen with such scale defects. That a number of lenses seem to be missing any type of trivial quality control. Best part yet, we're not mentioning an entry level lens here, but one of their higher priced aiming towards flagship models.

Interestingly enough, I've also heard similar quality control misses which have caused the delays of the new full-frame 70-200

Hoping Pentax pulls it together in the next six months or so, especially with release of a full-frame body (also imminently delayed, most likely not seeing the retail shelves this year). Imagine the first digital Pentax full-frame body hitting the shelves with defects?

Not too far from that in america today,

Most cameras above pocket cameras banned at events such as concerts. Even if a concert is held in a free public venue and is uncrowded (ones camera does not get in way) video still only permitted to be less than one minute. Most camera outfits banned at most professional sports, unless one has a press pass for on field use only.

Start taking photographs at public parks with any minor in the viewfinder then one is subject to all sorts of goodies. in america it is much like a police state, not much different from North Korea

Strongly weigh manufacturers ink versus ANY type of replacement ink. I've used a variety of printers; from near entry level to two units costing well over 10k. Almost all of the printers out there; from Epson, to Canon, etc... most are able to clearly detect manufacturers replacement cartridges versus other ones. If anything is used outside of manufacturers ink and/or cartridge, then it voids the entire warranty on the printer,

There also are items such as paper. One gets what one pays for

If it is a 35mm lens then one should not have a problem with most of the lens varieties in that focal length, with items such as vignetting.

For that particular filter size (49mm filter), the best choices for variety are places such as ones located in NYC

I've recently added a Canon EOS 5DS R to my collection.

I have the Sigma 300 for PK, and have never had one single issue with it; with thousands of photographs taken with it, in most every type of lighting, etc... Got to even borrow one in the Canon lens mount, basically identical.

Have the entire existing Sigma WR line in Canon lens mount, nothing short of epic. About the only glass made that can beat it is in the range of the Canon 200 f2.o or Zeiss. It's sad that Sigma makes these even for Sony but not for Pentax.

This is one of those ones where I most definitely would not mind Sigma coming out with the Sigma 120-300mm f2.8

Used on any other body outside of the not yet available PK, it's been quite widely accepted as one of the best WR zoom lenses ever built

The Sigma 150-600mm also quite well up there in both optics and unparalleled levels of WR. Sure the aperture could be improved, but look at the price.

Although presently not officially confirmed, Sigma is widely believed to come out with some nine more WR lenses within the next eleven months

Will most likely have to wait at least eight months from now to find out the answer. The original November release date is long gone

Once one downloads camera photographs (and data) onto a computer (then later onto the internet), most any camera made in the last ten years is completely traceable. Not as much as a laptop computer, but still traceable. Once the new owner uses it, and then downloads images it will turn up
