The K-x and My First Opinions



After all the rumours in these recent days about the upcoming new Pentax DSLRs and the K-m replacement, the K-x is announced today.

Before starting to say what my brief impressions about the new camera, I would like to mention that I was the one who previously suggested this name for a new Pentax DSLR, back to April. Well, Hoya, thanks for at least taking one of my suggestions, finally! ;-)

The K-x is actually a "me too" product, just like the D5000 and the 500D, with similar features and similar price (but maybe just a little bit cheaper at this moment - but C and N will cut their prices anyway - they always excel to cut throat!). Despite this, I think Pentax/Hoya has done the right thing actually - in order to compete and survive.

As for the special edition colours, I think the red is just too sharp to my eyes (maybe some girls and ladies would like it) and it is a little bit more close to orange, but not in pure red. The navy blue is more "normal", it just like what the Panas look like in some of their cams, as one of the standard colour options.

In fact, the K-x is a K-m body housed with an updated Sony sensor and associated AD converter and circuitry. It yet has some improved specifications over the D5000 on the effective pixel (0.1MP more) and the frame rate (0.7 fps more).

But first of all, there is one very worrisome thing. Still, this new camera is powered by AA batteries! What? My pardon?? A LiveView sensor (so does movie recording) consumes a lot of *power* (yes, instantaneous high *power* demand and a lot of *energy*), AA rechargeables with the ancient NiMH technology simply cannot help and it will fail to get the job done. Such a design is totally non-sense at all, technically. In fact, my plain old vanilla K-m is still suffered from the classic old Pentax DSLR AA battery issue and symptoms and so did my *ist Dxs and K100D - this has been a persistent problem for 6 years now since the original *ist D. How dare and "brave" Pentax/Hoya are for such a move (or actually no movement!), of which such a stupid and problematic "design" must be adopted! They are really so stubborn and plain stupid after all! :-(

In addition, what I would tell is that the K-x is now (about two weeks ago) only under Alpha testing, for what I have learnt (That's also why what you can see in the "brief hands-on" at the DPR is so "brief"). Those Alpha units are not yet be capable of making any still pictures! Yes, just still pictures, not movie clips! As such, I am afraid that Pentax/Hoya actually has made the announcement too early in advance than the product is mature and ready, especially consider that this time they have used a "new" sensor - at least it is new for them and there would be a lot of the "new" development works to be involved, done and completed.

As for the K-m, I think any interested user can still get it within 2009, as long as stocks last. Well, Nikon has yet just marketed the D3000, which is similar in specs and design concept as the K-m, as the lowest end and cheapest DSLR product in the line. So, it would do no harm to keep K-m in production actually, as it is still selling well in the Japanese home market and far better than the K-7 (See the Japanese BCN sales ranking here and verify yourself). But then Pentax/Hoya is not Nikon, in view of their limited production capability and resources.

Btw and anyway, I do have more faith and confidence on the K-x as it now uses a Sony sensor (which is for sure better and less problematic than the Samsung's ones, that used in the K20D and the K-7). But on the other hand, the AA battery "solution" will be the biggest evil in the K-x, I'm sure, especially when the user uses LiveView or Movie mode(s) for a little bit longer time. The chance for the K-x to use most of the infrastructure of the K-m is very high. Since K-m is still suffered seriously by the AA battery issue, what could I expect for the K-x??

Last but not least, I do believe the *only* rechargeable battery solution for *modern* DSLRs is a Lithium solution (no matter Li-ion or Li-Ploymer). And with such AA battery DSLRs, I guess most of the people cannot tackle the problem by themselves if they want to have a reliable and stable *rechargeable* power source, as they are not engineers nor technical persons in the field. Even they are, they have to do some kinds of (or even a lot of) hacking and sourcing of materials before the problem can be resolved, like what I had successfully overcome the problem somehow previously (but I believe it is still not as good as a *total* lithium solution!).

Four Sanyo Eneloop AA batteries will give you roughly the same juice as a typical Li-ion pack used in other entry-level DSLR's. Get over it.

Low-end Pentax bodyes don´t need higher potencial, but if you want it, you can buy the lithium AAs and you have some potencial (maybe higher) like a li-on pack. So the AAs in Pentax bodies is big advantages..
RiceHigh is damn right with his opinion about the using of AA rechargeable batteries. You are forced by Pentax to buy Eneloops and a good charger and that's not friendly to customers, futhermore LiIon is more reliable than four AA style batteries. Pentax should give their lower class cameras the LiIon battery too. Canon and Nikon never used these stupid AA batteries in their DSLRs.
Using AA batteries is convenient and not convenient in the same time. For example, when I shoot a long event or wedding, AA batteries will actually help because they are cheap, easy to get, relatively last a longer time (when shooting using viewfinder), and you can use AA for flash gun or battery grip as well.

Lithium batteries, on the other hand, is convenient and more reliable, but they are quite pricy and not as versatile as the AAs.
Back to the topic:

I think this a very good camera to fill in the gap between km and k7. What i like the most of this camera is the fact it is cheaper than most of its competitors.

I wrote a comparison table here ( http://www.radiantlite.com/2009/09/pentax-k-x-vs-... ) between this camera and most of the competitors cameras (Canon T1i, Nikon D5000 to Canon XSi, Sony A500, Olympus E-620). This camera is cheaper than most of them, but the camera features are quite similar.

The main weakness of Pentax could be marketing. They need to send a message out there that focus on value. You can get up to date features without spending a lot of money.

When you are travelling somewhere, you can easily purchase new AA alkaline batteries almost everywhere. With custom batteries, you have to deal with charging them and it's not always an easy task to do.
Custom batteries are difficult to find when your camera becomes old, but AA size is always worldwide available!
I have Pentak KM and alkaline batteries let me to take thousand photos before replace them. I can use NiMH rechargable batteries too... I think it is a very good choice.

Just one question:
Will the K-x share the mirrorless Life-View Mode of the K-7. I mean I read that the K-7 can do live view stills without the down-up-down mirror process of other LV cams.
Will the K-x be the same?
"In addition, what I would tell is that the K-x is now (about two weeks ago) only under Alpha testing, for what I have learnt (That's also why what you can see in the "brief hands-on" at the DPR is so "brief"). Those Alpha units are not yet be capable of making any still pictures! Yes, just still pictures, not movie clips!"
No kidding... then, how did they made these samples: http://www.pentax.jp/japan/imaging/digital/slr/k-...
Don't tell me they finished it in 2 weeks, from "not working at all" to "production or near-production quality"; obviously, you don't have a clue but you decided to throw a rock at Pentax, they deserve it, those b******s <rolling eyes>. How many such "mistakes" are here, on this blog?
As quoted from above "Those Alpha units are not yet be capable of making any still pictures! Yes, just still pictures, not movie clips!" ). I dont know how you got this conclusion.

Pentax already sent K-x cameras to medias for testing probably two weeks ago, chinese website has sample pictures available, here is the weblink http://article.pchome.net/content-970123.html

I still remember those K-7 "production firmware" samples with version 1.0 marked in the basic EXIF fields were just edited when they only did those with beta firmware 0.2 to 0.3 on beta cameras.

The manufacturer can do anything they like and wish. Of course, they can have a production K-x now in their workshop but they just don't even give one to the DPR or anyone else for testing. But if they had it already and it was ready, why not? Had DPR received a workable unit earlier, they should have already published a preview, and even with some "preliminary" samples, like what the DPR have been able to do with the recent Oly, Pana and Canon models, but just not for Pentaxes, never before indeed.
..... using rechargeable battery will rise sells of this model by 30-40 % ....... they made good body but this move with the batteries is bad. They are lagging behind competition so they should offer something more than c/n to gain market share.... offering less is mortal for pentax.

Nothing else to complain about, so you complain about AA batteries? How pathetic. Turning off the back panel turns the camera into a film camera? Really? What film do you shoot then? And where do you insert it? (I have a suggestion.) Turning off the LCD is indeed a decent suggestion for optimising battery life, if you really need to. Some of us are photographers and can manage with a viewfinder. But of course there is no real battery life issue; it's just another RiceHigh invention.

No matter what Pentax do you will be there to make inane criticisms. Please tell me what you expect to see in an entry-level system? Then I can turn on my RiceHighBot and punch holes in your idea.

In the meantime the rest of us will get on with photography, something you seem unable to manage.

First my own opinion: The target market (first-time DSLR users, Mums and Dads etc) perceives AA's to be more flexible solution as they are too busy in their daily lives to always have a Li-ion fully charged. It gives them great confidence knowing they can purchase some cheap alkalines as a short-term and emergency measure. Similarly there are low-end P&S's that stick to AA's for the same reason. Would Canon continue to sell such a camera if there was no market for it?

Of course the "experts" prefer Li-ion and prosumers do too, and hence won't have a camera at this level on their shopping list anyway. Or they buy another brand - that's consumer choice!

Secondly, Mr Ricehigh, if you want to avoid the MANY personal flamings that you receive, then do one of two things: either change your blog to a more balanced style and present some positive viewpoints; or change your blog to Pentax Criticisms. at the moment you misrepresent yourself and the end result is not unexpected.

Don't deny you must enjoy the attention and entertainment value of baiting people with your posts. So go for it, it's your blog so you can say what you like - but don't complain when others take issue with you and occasionally get a bit upset! Otherwise close the public comments section as per Ken Rockwell; he has a lot of detractors, but also gets a huge amount of respect, and he ignores it all and just gets on with the job.

michael,

you are really an idiot.
nothing pentax does is good enough. there is always something that is missing or short.

the K-x is a entry level camera for god sake.
evaluate it for what it was designed for not what you want your $650 to give you.

If you want ALL those features, then pay $2000 or $4000 or $8000 for something form Nikon or Canon.

geeze.
grow up
I don't understand the complaints about using AA batteries.

The Pentax uses 4x 1.5V 2300mah NIMH AA batteries for 13.8 Watt/hours of energy.

A Canon 5D mkII uses a single 7.2V 1800mah battery for 12.7 Watt/hours of energy.

Seems like the Pentax has 8% more energy available.
I think you do not really quite understand the relationship between operating voltage, cut-off voltage, power and total energy delivered. I recommend to read my old but detailed technical article about all these:-

What's the editing workflow? How best to bring these motion-jpeg files into Final Cut Pro for editing. Does it make sense to convert
to convert to Apple ProRes?
