duckling: While Mr. Pelkowski seems quite well informed and honest, it would be nice to hold a more in-depth discussion on the potential of sensor movement in achieving various photographic goals. For example:* automatic horizon leveling* tilt and shift movements* Z axis travel to focus MF lenses* automatic panning while the camera is stationary
duckling wrote..."* Z axis travel to focus MF lenses"
I doubt that the Z-axis movement (sensor forward/backward) would be more than +/- 2mm. Probably not enough to fully compensate for the adjustment range possible with a helicoil lens focusing mechanism. Might help though to provide a final adjustment if you're already close to being in-focus.
I wonder how Olympus avoids tilting in the sensor as it moves forward/backward? This would manifest itself as one side of the sensor (L/R, T/B) having a different level of focus to the other side, with the centre of the sensor having the best focus.
A good interview that strikes a satisfactory balance between just trumpeting market spin and overly-guarded responses. I got the impression that Richard Pelkowski may be a genuine enthusiast.
It's interesting how Olympics, (and perhaps Ricoh with the GR), take firmware releases seriously, not just for bug fixes, but also to enable new features. And to seriously listen to owners and reviewers feedback about what should be changed or added.
With form-factor changers like the Ricoh Theta, Olympics Air, Ricoh WG-M1, and the Sony Action Cam range, companies are responding to the different ways that still & video cameras are being used. While the traditional form-factor best suits most users, it doesn't suit all users and the way they want to use their cameras.
And with programmable imaging systems with interchangeable lenses like the Air, the flexibility of how a camera can be configured, used and controlled is tremendously expanded.
Interesting times ahead...
I like the bit about the use of a more complex chrome-plating process out of concern for the welfare of Sigma's staff. That seems to be an advantage of a family run relatively small concern.
One thing I'd like to know, why were there so many QC problems in Sigma lenses a few years back? Centering issues seemed to be endemic at one time.
I hope the coming FF Pentax has the option of electronic first curtain shooting.
I wonder why an electronic FC isn't offered in the 645Z?
Vlad S: Compare this interview with the recent one of the Fuji exec. So much more interesting information in here!
A recent interview with Ricoh about Pentax FF was pretty woeful too. Virtually no insights.
Good on ya, Sigma!
star shooter: In pic 7.. it shows the lens is just another amateur trombone style lens. That would be it's weakest point. Over time that style will get loose and easily knocked. Definitely not a pro lens nor would it be weather sealed either. Great for an amateur but not for PJ work.
I've got a DA* 60-250 f/4 and shot a few few events (soccer & athletics) in the rain. The problem with a "trombone" zoom is that its length, and hence its volume, changes as you zoom, and this volume change pumps the moist air in and out of the lens. So fogging over an extended period (1hour+) is hard to prevent.
For this reason, it would be better if AW/WR lenses were internally focusing (IF) i.e. constant volume designs.
Wonder if Nikon could add Astrotracker-like capability with a special Astro VR lens, to rival what Pentax can do with its O-GPS1, and track a celestial object for 300s without a trail? Perhaps it's not economically feasible without IBIS.
Is the Black Point high enough on this model Nikon not to truncate the noise distribution and allow good quality stacking?
I suppose some will be interested in upgrading to FF. I'm not.
Does this mean that Pentax users will soon have to chant the "You're not a serious photographer unless you're using FF" mantra?
Just Ed: Last month a bought yet another Canon 6D with 24-70 f/4 is L lens, which this time was just under 2300 after rebate (already received). I think the body alone can be had for 1300 now, mine was 1500, after rebate. All US warrantied.
I applaud Samsung's efforts, but their line holds little interest for me at the suggested price.
> Canon can do better job in high iso ADC than Sony sensor to compare. There is proof of that in 5D MKIII or so.
At high ISO it's the sensor's RN rather than the ADC noise performance that determines overall system performance.
Canon has a better sensel-level performance, but the ADCs in Sony Exmor sensors are currently still much better than Canon's efforts. Hence you'll see the mention of "High ISO DR" (where the sensel's performance becomes significant) almost always used in relation to Canon cameras, while with other brand's cameras DR is is usually referring to the DR at Low ISO (where the noise performance of the ADC is most significant).
quezra: NX1 is too much of a halo product and too little of a useful day-to-day camera. The price needs to come down before it can compete with the other mirrorless flagships, never mind DSLRs. This looks like the camera equivalent of the critically-acclaimed, tanks-at-the-box-office movie.
" The price needs to come down before it can compete with the other mirrorless flagships, never mind DSLRs."
That statement only applies if you consider a MILC as inherently inferior to a DSLR. I don't. I have both. Horses for courses.
I think the rate of development in MILCs is faster than in DSLR and eventually they'll overtake DSLR.
I think the NX1 is competing on performance & features, not on price.
JPEG2000 vs BPG - Small. I don't like what JPEG200 does to the detail in the red player pants near his right leg.
JPEH200 vs BPG - Large. on the detail in the green band. Does the best of the lot, but still loses quite a bit here compared to the original.
Jan_Shim: Such a shame Paintshop Pro doesn't play nice with Nik plugins. Nik has confirmed in writing that all new releases are no longer compatible with PSP. I use Nik and Topaz plugins and in order to continue them for compatibility reasons, I am running PSP X6 32-bit as my main photo editor. I have tested both 32 and 64-bit version of PSP X6 and found no performance difference between the two.
"Wonder who this was aimed at? Now this comment is just wasted space."
mauritsvw, I think it was aimed at me because I said that the PainstShop Prop download is a fully-functional 30-day version, rather than a demo version. I was not being pedantic. For me this is an important consideration.
When evaluating a new image processing program, I have to use it for some time to see if I can adapt to it or can record/edit a script for it that does what I want. I'm not prepared to invest this time if every image is bookmarked or size-limited. I process about 1,500 images/week. At the end of the trial period I will then purchase a product if I'm comfortable with it. That's the process I followed with PaintShop Pro & SilkyPix Developer Pro purchases/upgrades, Topaz Labs' Detail & Remask, FocusMagic (although the version only allowed 10 saves, so I had to make up my mind quickly).
I equate "demo" versions with crippleware and usually don't bother with them.
Michael Piziak: No need to buy any retouching tools now that I've got Gimp.
Netmage: "Ease of use counts for a lot, and Gimp hasn't had a lot of that historically".
While I've been a PSP user for a long time (v3 -> v14), The GIMP is quite good at rotation (if you use "Corrective Rotation") and perspective correction:
ozgoldman: Corel has an appalling record of ripping off clients outside the USA. At least 30% more on average than within the USA and Canada. And they wonder why people won't buy it.
Buy the downloadable version off Amazon.com for a good price. You can give a US address but you download it so there's no need to get a disk.
"Just download the Paintshop Pro demo."
A "demo" version can mean that it often has has reduced functionality. It's not a demo version. It's a 30-day full-version trial.
Ednaz: I was wondering when someone would just write the AA simulator in code.
I like the colors. I had a blue Panasonic m4/3 and I used to tell people that the blue cameras took sharper pictures... but more seriously, for cameras that I'm using just for personal work, I really liked the unconventional look of the camera. Oddly, the blue camera got less attention than any of my black cameras when shooting events.
It probably depends on the dynamic performance of the SR/composition motors. Not all recent Pentax models may be using the same SR subsystem.
I wonder up to what shutter speed this model will offer 1px & 0.5px movement capability. The K-3 could move the sensor at a 500Hz rate, enabling 1px AA simulation at up to 1/500s and 0.5px correction at up to 1/1000s.
This camera has slightly larger pixel pitch, so it may not be able to to quite reach this speed.
The SR of the K-S1 has a CIPA-rated SR of 3.5 stops which is the same as the K-3 so it may well be the same beefed-up SR system.
Michael Piziak: Yet again, a new Pentax camera that sticks with the same k-mount that they've been making since 1975 [film cameras].
Kudos to Pentax !
Unlike Canon & Nikon that changed their lens mount when they went digital - making them basically proprietary as the old lens wouldn't work on the new Canon or Nikon dslr.
Also Kudos to Pentax for keeping the image stabilization in the camera - so all those old lens, since 1975, which still fit on the camera and allow the user to still have shake reduction as they shoot !
Not just K-mount lenses. The SR in any Pentax DSLR will also stabilise M42-mount lens like the popular 50/F1.4 Super Takumar. My copy is from about 1971.
Cameracist: So, just like Pentax SP coating? Used even on the cheapest of lenses like the 35mm F2.4?
Yes, as you've stated, SP is used even of low-cost recent Pentax lenses. I wonder if Nikkor is going to reserve their flourine lens coating only for their top-end glass?
BozillaNZ: So int he end Pentax still can't produce any full-sized sensor cameras! It's either Cropped 35mm or cropped 645, Pentax is for Croppers! It's sensor is far smaller than theactual '645' model number suggests, no matter how you fans spin it.
Sorry, Photomonkey. That reply was meant for BozillaNZ.
Photomokey, since you seem fixated on FF (the only '"true" uncropped format), just think of the 645Z as a Super-FF format, with a 66% bigger sensor area than FF, and thus a potential 0.75 stops better SNR than "standard" FF.
Unfortunately, when Sony designed this sensor, which has so far been used in the Hasselblad HD5-50c, Pentax 645Z & Phase One IQ250, they skimped on the sensor area and didn't make it 60mm x 45mm. But all 3 camera manufacturers are marketing their products with this sensor as "MF" cameras. Damn liars!!!
Unfortunately, it's difficult to find any digital "MF" camera, 645-format or otherwise, with a 60mm x 45mm sensor.
