On article DPReview TV: The best deals on used cameras (78 comments in total)

My pick would be

Pentax K3
Sigma 8-16
Sigma 17-50/2.8
Pentax DA18-135WR
Pentax DA55-300PLMWR
AF540FGZ

And you are pretty much ready for 90% of shooting :)

geo444: Everything was off to a flying start with the K-5, their *Best-Seller* in 12 years with its excellent Sony Exmor 071 sensor :
http://mecastronics.free.fr/BestCamAstroLongExpoLL.html
Then, they missed the Mirrorless turn. The K-01 was restricted to "K" lenses, its AF hesitating too slowly. Better buy a K-5 ! The Q range was far too "simplified" for the price, too many features were blocked :
http://mecastronics.free.fr/PentaxQ10AstroIR.html - with a 1" BSI and Full Features, it would have been a best-seller, as was the NX-mini : http://mecastronics.free.fr/SamsungNXminiTopIR.html
Then, they lowered prices with old sensors, revamped by an increasingly strong Raw NR "accelerator", smoothing closer and closer to base ISO. Then, they gave up the 645 that could have been their Cash Machine. And now, here is the "K" Final ?...

Yes, K-5 was a camera that attracted a lot of buyers. Then Ricoh stepped in, K5II was just something to fill the gap. Everybody awaited K3, but initial firmwares were rather horrible and this quite good camera was selling less than K5 before. But they managed to fix issues and with latest firmwares it is a very solid camera. Then... they created K3II which is the same camera just with ugly GPS dome instead of flash. And it went downhill since then. K1 mistake that blocked APS-C developments, KP that was not K3 suceessor and large amount of users leaving.

Similar with entry level.. K50 was also selling in huge numbers, but over time the solenoid issue developed into large scale problem and entry-level useres experienced such problem in most cases just dumped Pentax and switched brand.

PENTAX K3 III RAW images still missing in comparison... :(

xmeda: If only it can have top info dot matrix status display like other cameras have.. There is plenty of space for it.

Even much cheaper cameras have top info display. It is added cost, but compared to rest of camera it is something like 2%.

Theo Ghefner: Where are the efforts regarding the 200 mm Macro reviving, some good news about a new FF body and a potentially awaited refresh of the 645 Z which include a new 100 MP sensor?
If you'l look around for any non Pentax lens, the research result is going to be a resounding Zero, because Sigma, Tamron and Tokina are not making any of their relatively new lenses(DSLR) any more, and adapters for K mount are almost nonexistent.
And speaking about the new Macro, as far as my math knowledge goes, 1.5 x 100 = 150, then the question begging to be asked is: by which magic calculation 3 more mm were added?

645 is dead, 6 years without ANY product introduced

Richard Murdey: This is just a DFA WR with HD coating and upgraded weather sealing. Calling it a new lens feels like overreach.

10 elements instead of 9...

razorfish: 48 mp… and some idiots still claim that APS-C cannot handle more than 40… (used to be 24 before the Fuji X-H2). Yeah right! APS-C handles 100 mp with ease and larger sensors aren’t needed, strictly speaking. That’s the fact.

100Mpix @ APS-C only If you want to shoot at ISO25 with whole image completely re-constructed by AI from huge pile of noise without any dynamic range, then you can be happy with this...

But in reality even images from Sony RX100 mk1 totally wipe these phones in many aspects.

APS-C with 32Mpix is produced by Canon already, but has issues with diffraction impacting images with F11+. Something around 40Mpix APS-C is probably usable maximum. But you can still easily use sensor shift and create picture out of multiple shots to reach much higher resolutions for stationary objects.

Disposable cameras are HORRIBLE idea. Especially when you can buy cheap 2nd hand regular film compact camera..

Such cameras were also used on various microscope systems or automated tools, so there might be some deal about this that needed to be covered...

xmeda: Im APS-C user since 2008 having no need to move to any larger sensor size. My lenses cover 8-500mm + TC which is equiv to 12-750 + TC FF field of view. All on Pentax with IBIS. Many of those lenses are FF capable in fact, but APS-C is using the best part of their image omitting weak edges. Recently I've added one small M4/3 as travelling companion.

Unless one needs extremely high resolution and is willing to invest heavily in hi-end lenses to use such resolution, then APS-C is well enough. And in case one is willing to do such investment, then there is also medium format with very similar prices, but offering even better image output. This is why old Pentax started with APS-C + medium format strategy. And this is why Fuji is now using the same strategy.

RE: miric - with FF DSLR without IBIS option they were done, with FF ILC they are alternative, but then it is not as portable as APS-C and also not as hi-res capable as medium format. It has its customers, but it is still bound by that very old receptor size dictated by cinema film medium which was nothing else, but very cheap option how to enter photography :D And since digital era started, there are no such limits. So we have more convenient APS-C and we have digital medium format that continues what serious 6x7 started on film.
Personally I see very little need for 35mm FF systems as those are only filling the gap, but in fact they combine both issues. They are large, heavy and expensive, yet they do not offer same image output as MF that is very close in that size, weight and cost.

And if somebody tries to tell me that FF is portable, please show me for example equivallent to APS-C + 18-300mm or 18-400mm lens in FF world :)

Similar with M4/3, which is interesting format too.

It will be nice if Sigma will re-introduce the mighty 300-800/5.6 with updated motor, IS and for new mounts.

Needs to support Sigma and Tamron K mount lenses to be really usable as backup/Kmount saving tool..

gavinlg: This is actually an f6 lens in real world terms, get it right dpreview. Obviously Hirada-San doesn't know anything about equivalency either - an f6 lens just isn't enough for space photography. Professional space photographers would never use anything slower than f2.8 - Ken Moonrockwell said so and he's a pro that's actually supporting his growing family.

gavinlg

It is 300mm F4 lens. Period. There is no equivalency. Sensor size has ZERO impact on LENS parameters. Just if you crop and change distance to get comparable field of view, then depth of field changes. But not the exposure.

Apparently last not-stabilized 300mm lens which can be autofocused just by mechanically moving one group as it had an option to do AF from camera via mechanical coupling.

K mount for Pentax! Finally some wide angle FF fast lens for Pentax. Unfortunately manual lens only.

In reply to:

mermaidkiller: Why not RF / Nikon Z / Sony FE ?
The much shorter flange distance means lighter construction of such a wide angle lens.

You can adapt Fmount to Z mount easily,

Nielk Mike: Compared RAW to the Fuji X-T4, the Sony a7R III and the Fuji X-E4. All three outperform the OM from 800 ISO, clearly visible at ISO 1600, and really bad at ISO 3600. Not that I am surprised. It is a smaller sensor. What surpises me mostly that M43 folks claim comparability.

So you are putting A7RIII into comparison? Seriously? And are you looking at what? Set it to RAW and you'll see that it is actually very good output comparable to APS-C cameras.
