I could use a tropical vacation.

To circle back to the topic at hand, I've heard a rumor that Nikon will cease it's camera business due to overwhelming ennui, while Leica will cease it's camera business due to lack of profit. That leaves Hasselblad and Sony, since all the rest are too insignificant to count...

The reports of Ricoh Imaging's death have been greatly exaggerated.

Thanks for the link to the official rebuttal.

Up for sale is my old K-5, a spare(!) 10-17mm fisheye zoom, and a DA 40mm XS super pancake.

Shipping is $10 anywhere in the US (even Hawaii, Alaska or APO), and I accept Paypal only. Can make a deal for combination offers, as well.



Pentax K-5 body: SOLD

I am the original owner, but haven't used this much since I got my K-3 (and a few other cameras... ahem). It has 28,809 actuations, and a few scratches on the read LCD. Otherwise, in excellent condition, perfectly functional and ready to keep shooting. This is for the body only (with body cap, of course), but nothing else. I can also include a battery and Sunwayfoto L-bracket for another $25.


Pentax DA 10-17mm fisheye zoom: $250

Excellent condition, only minor signs of use on the zoom ring. Glass is perfect, and aperture and electronics work as expected. This was my backup 10-17mm (for shooting panoramas) and was very rarely used. I love the focal length and effect of 10mm on APS-C, which is why I'm keeping my other 10-17!


Pentax DA 40mm XS ultra-pancake: $125SOLD

The kit lens from the K-01, and the smallest APS-C prime you can buy. Not much bigger than a body cap, but incredibly sharp even at f/2.8, with very fast focus (since there's not much to move). This is a great "normal" focal length for APS-C, but since I purchased a 20-40mm Ltd, this has been languishing. Includes the hard-to-find rubber front cap and standard rear cap, and I should have a box and papers for it somewhere (though I did just move houses!).


Now the pictures:

IRIX 15mm blackstone focus doubts
Posted By panoguy

Ciao Mauro,

The focus (if you call it that) is either completely off (you are focused at the closest focus distance) or the lens is badly de-centered. I wouldn't accept any new wide-angle lens with that quality.

But, before you send it back, two questions:

1) You shot at f/2.4 at 1/8000 of a second - did you intend to shoot the lens aperture wide open? (If not, does the lens have an aperture lever sticking out of the back for Pentax mounts? Meaning you can control aperture from within the camera.) The reason I ask is because most lenses are sharper stopped down a bit, and wide-angle views of landscapes or architecture need even more than that (like f/5.6 or f/8). You can hand-hold it down to a shutter speed of 1/125, so a smaller aperture (higher f number) should be no problem...

2) For that shot, was the focus scale (if there is one) at or near "infinity" (which is the end of the scale)? If the lens focuses beyond infinity (many do), that may be part of your problem. Take some test images at infinity and a bit less than all the way out, to see if there's a difference.

HTH

Item for Sale
Laowa 15mm f/4 ultrawide 1:1 Macro FF shift lens

Asking Price
350.00 USD

Item Location
Washington, D.C. (United States)

Item Description
Selling a pristine LAOWA 15mm ultrawide macro+shift lens from Venus Optics. You can read more about this incredible lens on their website here.

This is a manual focus, manual aperture (as you'd expect from a shift lens), full frame lens in Pentax K-mount. It can focus down to 1:1 macro reproduction, albeit at less than 1" from the lens, and actually has pretty good bokeh for an ultrawide. Works well on a K-1 (no vignetting, except when heavily shifted), even though my samples below are from a K-3.

Includes box, papers, caps and removable hood. Focuses smoothly, glass is perfect, aperture is not snappy, since it's a stop-down and shoot kind of lens. All in all, excellent optically, mechanically, and cosmetically. Hard to tell from a new lens, except for the dust... which is why I'm selling it. Just don't use it that much. Thought I'd do astrophotography, but have realized I suck at staying up late! ;)

Did my virtual ears prick up? :lol:

Thanks for the props, i_o. I'm just a technician with lots of experience, but your spectacular work is art. (Really got get to the desert some day to shoot stars like you do!)

Rob, I replied to the thread on DPR about panoheads, and said the same thing that was said above. Nodal Ninja. Go to nodalninja.com and email or chat them any questions you have. Even call them if you're in the US! They know a tremendous amount about panoramic photography (unlike most makers of pano gear) because that's almost all they do and sell.

Unfortunately, I've been swamped lately, so haven't had time to really delve into these threads, but I'm aware of them! PM me if you have any direct questions, and I can get back to you in a few...

Can You "Learn To Love" A Focal Length?
Posted By panoguy

That's almost exactly my experience with the 40XS. I loved it so much, I bought a second as a gift for my niece because she only had the kit 18-50 that came with her K-S2. It's her favorite lens now, too (and my brother, her father, is jealous because he shoots Nikon).

For me, it was years of buying zoom lenses because "they are more versatile" but then I'd always shoot at one end or the other of the range (which I suspect is how most people use zooms), where most of the affordable zooms are not the best. Got a 35mm Limited Macro when they first came out and used my feet a bit, and it has become my second most-used lens (after the 10-17mm - don't ask).

So, I'd never "learned to love" any zoom. Then I got a 20-40mm Limited for a great price, totally prepared to say "redundant and not worth the replication of two of my favorite focal lengths (40 and 35)." Lo and behold, I actually like this lens, mainly because 20mm is a nice compromise.

what has been your most "disappointing" lens?

Sigma 120-400mm, no contest.

It was the "cheaper option" compared to the 150-500 and 50-500, and after only two days I knew why. Totally soft and fuzzy at 400mm, and focus was slow (but not quite DA*50-135 slow). Sent it back in exchange for the 150-500mm, which was stellar for the price (at f/8 quite nice, really).

Item for Sale
Tokina 500mm f/8 mirror lens

Asking Price
150.00 USD

Item Location
Washington, D.C. (United States)

Item Description
Ah, the mirror super-tele... what a strange and wonderful beast! This is one of the best ever available for Pentax (far better than those cheap "new" ones on Amazon), with only the Tamron adaptall being a smidge better. The difference is that this mirror lens has a dedicate K-mount.

Focus is smooth and easy, and the results are very good for this type of lens (mirror lenses work like a Cassegrain telescope, with two convex and concave mirrors focusing the scene into an image circle - the result is a 500mm effective focal length in a much smaller tube). The typical "donut bokeh" of this lens design is present, but also the complete lack of chromatic aberrations that goes along with it.

This Tokina includes glass filters (intended for film use) that screw into the back of the lens, and all are included. In fact, everything is here as if you picked this off a shelf in 1984, from the faux-leather snap case to the filter wallet down to the Tokina lens-cleaning cloth!

Because many people might not be familiar with a 500mm lens the size of a softball, I've included some hand-held sample shots below.
