This advice only make sense if you have an older camera without native support of the DNG format (PEF only) that you want to use with a software not supporting PEF. But if the camera natively support DNG, there is'nt much point in importing the DNG in DCU only to export it in DNG...

With flash, on-board or not, it’s usually better to set the iso manually. As many said above, the camera can’t know what you want exactly... Thus it just uses a combination of settings that will get a usable exposure for most of the scene. Which can or not be yo your liking even if technically right.

Contrast and lines are much better rendered in B&W than in colors. This is also the reason why you can have a B&W overlay for sharpness adjustments in Lightroom. Much easier to see what’s you’re doing...

Ricoh's financial results for Q3: improved Smart Vision's earnings

No, the KP-IR isn't a "new" model. It's only a variation or a different version of existing model.



The difference is that a new design, like the 11-18, means that the manufacturer still have the will and capacity to develop and support their line of products. Rebadge and minor update of existing products mean the reverse. And when most of the launches are rebadged or updated product it means a lack of will or capacity (or both) to really develop the product outside of minimal maintenance. Which is rather worrying... There's a limit on how much you can do by making new stuff with old one.



It's ok if they make profits on compact camera, but this doesn't help either showing RP see much future in their DSLR line or have much interest in developing it outside the minimum needed to maintain the line.

The problem isn’t that Pentax ignore mirrorless. It’s they don’t do much on the DSLR side either... Nobody would talk about Pentax disappearance if they showed a solid commitment to their DSLR lines.

Because I definitely don't want to go back to chemical processing! As far as speed goes, although it's possible to take hours to process a digital picture, it's more like a few minutes... With film, it was like two evenings of 3-4 hours to get one decent print, assuming a relatively straightforward picture (correctly exposed without complex dodging and burning). There's nothinig wrong with working on film, but I definitely don't feel the nostalgia to go back to it.

The main interest of shooting B&W film is because it's relatively easy to develop and print your pictures at home with a classic chemial darkroom. Building a darkroom for color film photography is much more difficult. But if you don't plan on doing everything the old way, you might as well just shoot digital and develop in LR, or whatwever software, as a B&W picture. I don't see much point in shooting B&W film to have it developed by someone else and scanned to be digitally process. Today, shooting B&W film is much more about the experience of doing it the old way than the end result. If you're only interested in the result (getting a B&W picture), there's nothing you can achieve with film that cannot be achieved as well or better, but more efficiently, by using a digital camera and processing.

Exactly! Prices are high because the options are few for people wanting a FF WA K kens. And since we’ll not see a new WA prime anytime soon, the situation isn’t going to change for the foreseeable future.

The very slow pace at which they develop and launch new gear is much more concerning than the absence of mirrorless cameras. I hope the camera annouced for this year will be worth the wait but I don't hold my breath either.

Should I push my shutter speed or count on LR's ability to give me 2 shutter stops ba
Posted By CarlJF
Replies: 16

1. YMMV. My personnal experience is that 2 stops is a safe bet, 3 stops is about 50% success rate (so take at least two shots), and more than this is really stretching it beyond practical use even if possible (like 1 out of 10 will be OK, feasible but not really useful while taking pictures). And this is relative to what I can achieve handheld, not the rule of thumb (although I'm close to it).
2. Although it's possible to do, it's just more practical to get the exposure right in camera by shooting at a higher ISO. There's no significant difference between a shot taken at ISO100 pushed 2-stops in LR and one shot at ISO400... As others said, TAv mode is very useful in these situations. Set the aperture and shutter speed while letting the ISO float.

Short answer is yes, but there's no reason to either if you have better equipment on hand.

It's like asking if you could go the grocery store with a 20 years old car...

Even that... To be honest, it's much more a matter of processing than sensor technologies. And even if it could have been the case for the first few generations of CMOS sensors, it's certainly not the case with modern sensors.

Although 6MP is enough for anything, there's also no reason to prefer it over 24MP (or 16MP...). The higher MP count gives way more leeway for cropping, which often can prove useful. There's also a lot a differences between the technologies. It's not just a matter of MP. Newer sensor will also provides better dynamics and way better sensitivity than 15 years old ones. All in all, although it's still definitely possible to make portraits with 15 years old equipment (or even older!), newer equipment will make your life easier.
You also have to take in account that cameras with newer sensors also have a lot of other features. For exemples, if you're into portrait photography, modern eye focus tracking technology is a blessing compared to older AF technologies or manual focusing. Even if it was, and still is possible to make excellent portraits by manual focusing, decent eye focus technology will make it a breeze and provides a much more higher rate of properly focused pictures, which in turn will leads to a higher probability of a good one, all other thngs being equal...
So, to make a long story short, even it's possible to make good portraits with a 15 years old 6MP camera there's also no reason to use one if better equipment is available. And certainly no reason to downgrade from a 24MP camera to a 6MP one.

Pentax KP and sigma 18-35mm

Looking at the full review on PF, random focus seems a "feature" of this lens. They tested no less than seven copies on many different bodies and all had issues. So, I would not hold my breath when testing on the KP! Even if it works under the test condition, it wouldn't mean the lens is fine. What they observed in the review was unpredictable back and front focus varying with focal length and focus distance (and maybe even with aperture)... So, even if you could calibrate the lens to work fine under some specific sets of conditions with the dock, the issue will appear again as soon as you use other conditions. It seems the only "fix" is to work in liveview... BTW, this issue isn't specific to Pentax, it's also reported by Canikon users...

Pentax K-70 soft image issues
Posted By CarlJF
Replies: 7
Views: 868
It's difficult to say just with only this picture. As others said, it could be a back or front focus issue, but it also could be a misfocus. Unfortunately the data about how the picture was focused are missing in the exif. So, it's hard to tell... You could make a few test pictures using Liveview. If the softness disappear it would strongly suggest a focus issue. On a portrait like this, at 70mm f3.5, there's about 6 inches of DOF and even a slight misfocus could make the picture appears softer than it should be...


As said above, the lens is at its worst: longest end and almost fully open. So, some softness might just be normal with this lens under these conditions... What about other focal length ? Are the pictures still soft at 50mm f5.6 ?

Yes, I know. But, depending how much WR is really a must for the OP and not just a nice to have, a 2 years manufacturer warranty covered DA 17-70 for 300 $CDN (about 210 $US) was worth pointing out. Even if this lens does't have the best reputation for reliability, there isn't much to lose at this price... It could also be good to know for other peoples reading the thread...

Since you're in Canada, there's a used 16-50 converted to screwdrive at MacBain for 340 $CDN. You might even be able to barter a bit since I've seen it as low as 250$CDN when there was a clearance sale on used items a few weeks ago.

Edit: They also have an open box DA 17-70 which could be an interesting alternative to a used 16-50 or 18-135 since it should be covered by the 2 years Pentax Canada warranty...
