more K-1 camera comparisons

The mirrorless camera evolution is about many things, but size is a big one (ha?) Putting a 24×18 or 36×24 sensor into a smaller body with less moving parts saves cubic inches, grams and potential breakdowns. And presumably costs are lower, but of course that's not easy to prove.

However: the size factor breaks down somewhat since lens size still has to match up with the camera sensor lest the corners of all your images go dark.  Smaller sensors like 4:3 helps shrink the lenses - but then owners crave really fast glass to compensate for the smaller sensor size.. The 24×18 crowd want fast zooms with lots of great optics.  The 36×24 say "where is my fast gear?" The lenses are only a bit smaller for mirrorless than for dSLR for the same sensor since the lens must send light to the entire sensor regardless of body type.  And so smaller cameras (with small gripping areas) begin to spout large, unwieldy lenses requested by the users, especially at the telephoto end.  

My NX300 is great for short zooms at the wide end or for fairly wide primes.  My K-50 won't fit in any reasonable pocket even with a pancake prime.  Step up to the K-1 and you must accept the bulk whatever lens you choose - it's half again the weight of the K-50 but the cubic inches will also be significant! 

Looking at my current set of K-mount lenses, I am well covered in both 'FF' and APSc formats. So if the lottery funds flow our way it could be managed optically.  As to physically, it would be a shock - but the NX300 could be the easy-shot camera when it came to distinctions.
  • 36×24 "FF" primes = 28, 50, 135, 300, 400mm
  • 36×24 "FF" zooms = 15-17mm fisheye*, 35-105/3.2-4, 80-200mm f/3.5, 100-300 (15-400mm)
  • 24×18 APSc = 10-17 fisheye, 18-55WR, 55-300WR plus all the above (15-450mme + 600mme prime)
*10-17mm fisheye >15mm as shown on K-1 demo pages!

I swear I'm not actually planning to buy a K-1 any time in the future - but its features are enough to make me consider the benefits of strapping a massive camera to my chest.  I honestly did not expect that, as even the K-3ii seems like a lot of camera.  But everything that APSc flagship camera can do, the K-1 does better - and more features besides, many of which I find.. intriguing.

Below is a link to the specs, and a subset that highlights all the gee-whiz new-to-me features and improvements that my K-50 lacks.

For and against Proposition K-1

From imaging-resource.com
Arguments in opposition are short and easy.
  • $1800 that I don't have
  • 925 grams of beautifully-crafted bulk
But those in favor are numerous and occasionally surprising!
The SR rating of five stops is massive.  I hadn't considered that a larger mechanism for the 36×24 sensor would be more sensitive but it's clearly so.  The pixel-shift full color mode improved as well and can discard areas of blur in favor of clarity.
  Hmm is the ks2 clarity option in here too?  Yes it is! Clarity: adjustable ±4 steps

The third control subset is cool but better still to me is that the Info screen can be customized!  Focus points are more spread out, the APSc auto crop can be overridden.. so many things to please a photographer of any brand.  Good video too it seems, but R.Pentax continues to underplay the significance of video.  I am fine with that, having tried more video-centric cameras and been frustrated by their nearly-continuous AF.

As to items that I could like betterbetter?  The internal LEDs should be set very dim, and can they be red?

hey coincidences happen OK?

I recently decided to upgrade my old and power-hungry Big Desktop by adding some memory.  After failing to achieve any good result (no doubt the ECC or other subtle feature is off - why does every damn motherboard require a very slightly different memory chip??) I ordered a new Core system with 1TB  drive at a great price..

..on the very same day that the 36Mpxl Pentax K-1 is announced!  No doubt this bargain beast would need more processing power and a spare 1TB drive.. but it's just a coincidence.  Those really do happen!

The K-1 shows some incredible talent & potential and at a price much lower than anticipated by nearly everyone for a 36×24 sensor (same size as 35mm film, for bizarre reasons aka "Full Frame").  It's not for me - but less not so than I expected.  Hey I was trying hard not to get a new computer so that will have to be enough spending for now!!

So back to that computer.. this smaller frame will reduce power consumption, increase performance and has WiFi built in for home-net simplicity.  Just yesterday I signed up for an online promo that could win me a $500 Amazon gift card, and the first e-mail they send out is $150 off this little thing.  While it would be marvelous to get $500 back as well, the deal was a good one.  I could add 2G more but no $150 off; amazing what 2G can do to a sale.  And heck, maybe the new DDR3 10600 &c &c I bought will work in this one! :^)
