DanielFjall: All I can afford is vintage Leica glass, which is amazing. I bet this must be truly spectacular.

Not only that, but if prices are adjusted for inflation, this lens is not so expensive after all; I seem to remember mid-20th century Summicrons going for about $300-400 new. The price index in the US has, on average, gone up 1000% since then, so this optic is about twice as dear. Is it a better performer on a 24 mpixel sensor? That I dunno.

You too probably wont like watching it if you are a photographer !!

@CyberAngel -- No, unfortunately. Coppola was pretty clear the car was real. Hollywood does this all the time if it's cheaper or quicker to blow up a classic anything than to make a prop. In this case, it was obviously cheaper to find a 1948 vintage Alfa 6c 2500 with Farina body near the Italian location than to make and transport a fake. Remember, these were not particularly rare cars at the time and it was only 22 years old -- not yet even "vintage," let alone "classic."

In reply to:

noflashplease: Another huge and heavy E-mount lens? Lenses of this sort appear to use long flange optimized SLR optical formulas with the equivalent of short flange adapters built in. You really have to wonder if Sony is designing lenses from the scratch just to be awkwardly large or if it's just old wine in a new bottle?

Either way, I really don't see a point to this FE lens? Why did Sony even bother?

@Yake Leica angles the pixel receptors off-center to remove vignetting; Sony does not, so its lenses may not be able to use the short flange distance as well.

I had my own specialized tools -- but no microwave. I had a cheap immersion heater and a small container filled with concentrated developer solution; I dabbed hot developer on areas that needed more ooomph. I dry sponged highlights to keep them bright. I pre-flashed paper with light to change the response curve.

On the negative side, I diluted developers to increase sharpness (acutance.) I added sodium sulfite to soften grain. And some things I would still like to keep secret (which means I forgot them.)

KevinG: Amazing! As someone who embraced digital shooting from 1999 on it is just so eye opening to see how much would go into the making of a print for sale. I always loved the fact that once you had your "master file" set in digital as long as you stayed on the same inset & paper you were pretty mush assured consistency from print to print. It had to be so hard to remember exactly what you did when printing in the darkroom. sometimes even notes you write at the time are not 100% accurate.

That's why AA prints are worth so much more than anyone else's prints from his negatives.

Gatoraied: I had my own darkroom back in the early 60's and worked as a commercial photographer. I sent all color work to Rochester and only did my B&W's. Film was 35mm, 620, 120. Did lots of dodging and burning which worked quite nicely. When seeing Adams' multi light & toggled enlarger/projector light array I thought " Ahhh, thats how he did it!". Of course never using 8x10 negatives the thought never crossed my mind but it was brilliant!. For years many of us in the business knew Adams manipulated his photographs but could never quite nail down how it was done. Of course anyone who worked photography knew getting Adams kind of exposures were next to impossible and just thought he performed some magic in the darkroom but never realized that using that toggled lighting was one of his creations. Interesting to know the rest of the story. BTW, I wonder if National Geographic will purge all of Adams' photos from their archives?

Ah, hindsight is so romantic. I did the same, but I must admit I fell into the "discussion trap" of the time, trying to decide whether I was for "condenser or diffusion" enlargers.

Now, the discussion trap seems to be "equivalence." Some things never change.

On viewing the first in the series of the blonde, and using the 100% loupe, I thought at first I saw some ugly chroma noise in her sweater; on closer inspection, turns out that was the WEAVE of the garment.

I am impressed!

Nice bokeh, too. Reminds me of a 2.8 Zeiss Planar iirc Rollieflex from mid last century -- and that's a good thing.

Being a fanboi of Alfa Romeos and a former user of a Canon AE-1, I felt the same twinge watching this as I felt when that beautiful Alfa coupe was blown up (along with his bigamic wife) in Godfather II.

The difference is that any pawnshop can still supply AE-1s for cheap prices.

On article Special K? Pentax K-1 Review (2603 comments in total)
In reply to:

onlooker: It would have added a little ace in the hole for Pentax had it provided for interchangeable focusing screens to distinguish itself from the pack. Alas, no. From Pentax website http://www.ricoh-imaging.co.jp/english/products/k-1/feature/04.html :

"The focusing screen is fixed on the camera body, and is not interchangeable."

@miles green

Is it easy to acquire focus manually on the K-1 screen?

On article Pentax K-1 real-world sample gallery (143 comments in total)
In reply to:

AbrasiveReducer: Nice photos, but as far as I can tell, the pixel shift is the only thing that sets these images apart. So you have to be knowledgable enough about cameras to appreciate pixel shift, yet willing to roll the dice on a Pentax system. The night shot of Mt. Saint Helens is cool but so much has been done to it, it seems that the camera is almost secondary.

That is exactly the reason I find these photos most useful: I like to do similar things in pp and these shots show just how far the DR and IQ in general allow these tweaks.

I am re-thinking my decision to wait a year or two before committing lots of green to a K-1. Seeing these, I may not wait after all.

In reply to:

Richard Schumer: Perhaps I missed it, but what type of shutter does it use? The high sync speed leads me to believe it is not a focal-plane curtain, while the slow apertures tends to hint at a leaf shutter -- but where? In each lens, or in the body?

Does anyone know?

@joe_leads - Thanks for the info; I guess I haven't been keeping up with MF tech because I've been too busy saving my shekels for a 645Z....

@2joeA7R2 -- Thanks for the info; now I'm wondering how they managed to get a leaf shutter to cover a 55mm image circle and reach 1/2000 sec. That's some shutter!

futurewah: I'm always amazed there are people stupid enough to buy this sort of product. It's bad enough that Leica produces this sort of thing, but at least their items have a chance of holding, or even rising in value.

Who collects these lenses?

<<Who collects these lenses?>>

Last year, I ran across someone who bought a 200mm f:4 Pentax-M lens; he introduced himself when he saw I was using an older 80-200mm off-brand zoom lens (as a test) on my Pentax. He offered to trade and I accepted before he changed his mind. Turns out he wanted my zoom bc it was bigger than his, and he used lens size to come on to women for sex.

I swear this is true. In the US.

In reply to:

Androole: It's certainly bigger, heavier, and more optically complex than the current Voigtlander 35mm f1.2, so I wonder if it performs better.

While I have no hands-on experience with it, I must point out that the Voiglander 35mm f:1.2 is for a mirrorless (Leica M) mount rather than a DSLR, which is much easier to accomplish.

The kerlee has an ED glass element, while the Voigtlander has one fewer elements, but adds three aspheric surfaces, presumably for CA and field curvature correction.

Voigtlander has an excellent reputation, while kerlee's is unknown to me.

Disclosure: I own and use a Cosina 24mm f:2.8 lens from circa 1970 on my Pentaxes which I dearly love (Voiglander is a trademark owned by Cosina).

SmilerGrogan: How dare anyone blame LensRentals for supplying a bad lens? I have rented dozens of lenses (and bought a few) from them and all have been stellar. Look elsewhere if you seek someone or something to blame.

@alex wrote <<There was no pixel peeping back then, only photography ;-) >>

Oh, I've been a pixel (grain) peeper since the middle of the previous century. I learned a lot doing it, too; f'rexample I learned to avoid sodium sulfite like the plague in 35mm film developers if one values sharpness. Just don't make prints bigger than, say, 8x10 from a 35mm neg.

Now, I've learned that unless one is making prints measured in feet (or meters) all modern cameras are more or less equal. But I still pixel peep, trying to learn even more.

In reply to:

madecov: Congratulations to Hasselblad! as someone who lusted after one in the early 80's I for one am very pleased to see a new product and one that is so nice especially. Back in the late 70's I wanted a Mamiya Sekor SLR or a Topcon. The Minolta XK was on my wish list, I ended up with a GAF (Chinon) SLR. These companies are gone, I am very pleased to see Hasselblad has not gone the way of Kodak or any of the many others who are gone.

reply withdrawn.

NowHearThis: Meh. At that price I'll wait for the 200mp version.

</sarcasm>

It's likely Pentax will upgrade their 645Z sensor in the near future -- 50mp just doesn't cut it anymore, I guess.

In reply to:

Dudodelmundo: Has anyone tried processing the files with darktable or some linux based raw developing tools, yet?

I did when the camera was previewed by DPR with samples; if you use the latest darktable, (beta) the files are recognized and rendered correctly. There may not be a lensfun filter to correct lens distortion yet.

Darktable and UFRaw betas are available for Ubuntu/Mint through PPAs on the home sites of the apps and through backports for Debian.
