Have you done the arithmetic yet to estimate FF and MF mega pixels with NX1 pixel density?

Really?
Would you care to demonstrate how I'm refusing to accept whatever the future brings?....

Whining?

I'm not the one refusing to accept that the future is coming.

No, you seem quite interested in the future, refusing to accept whatever the future brings, frustrated that it probably won't conform to your desires any better than the present.
Further, you're not even in the market for whatever the future does bring until that tax refund comes along.

Pentax-Ricoh isn't at all ambivalent about what they mean by weather sealing.

From....
http://www.us.ricoh-imaging.com/dslr/K-5_IIs

"Fully weather sealed and coldproof design resists water, fog, snow, sand, dust, and more, for top performance in extreme field conditions as well as in the studio."

LuLa is impressed. A contender for the APS-C crown.
LuLa has trouble reading Samsung's spec page that they linked to in the 'review'.
Lula mentions the NX1's weather sealing, Samsung's page states;
"6 This product is not water or dust proof. It is designed to resist dust and minor splashes only. Exposure to severe conditions is not recommended."
 
Not impressed with LuLa.

Ultimately we don't get any choice.

Canon chooses what enables them to make the most money.

If EVFs can be built at a lower cost than OVFs and generate greater profit, which way is Canon going to go in order to keep shareholders, etc, happy?
dilbert, either accept what the market offers (as if you could afford it prior to next Spring's tax refund), or start/buy a camera manufacturing company, bend it to your desires.

Either way, please stop your incessant whining here on CR, save it for your wife or someone else, somewhere else, anywhere else.

EOS Bodies - For Video / Re: 5d Mk3 exposure pulsating
« on: November 21, 2014, 08:59:41 PM »

Thought it might be an LED light I was using somehow causing frequency interference....
Was the scene lit with LED Lighting?
Best I know, there are (at least) two electrical methods for driving LEDs, current control and PWM (Pulse Width Modulation).
Current controlled lights will be steady.
PWM lights do indeed flicker rapidly, the frequency of the pulse as designed in determines the rate of the flicker, the width of the pulse (its duty cycle, ratio of on/off time per cycle) determines the apparent brightness of the light.

I have a rather bright LED flashlight (torch) with three brightness settings.
Low and medium both use PWM, high is continuous.
I just demo'd this for myself (I doubt the concept will video well, I'm not even going to try) by watching spinning bicycle wheel spokes lit by the LED flashlight.
PWM makes the moving spokes appear as many multiples of spokes, continuous light just shows them moving.
 
If the frequency of PWM pulses is low relative to multiples of the shutter speed, yes, you'll be recording the effects of the flicker similar to the effects encountered when shooting a video display screen.
If the frequency of the PWM pulses can be cranked up to several multiples of the camera's shutter speed, the flicker phenomenon will still be present but likely not apparent (or at least less apparent).

Photography Technique / Re: uneven polarization
« on: November 21, 2014, 08:36:57 PM »
If I understand correctly, a polarizing filter filters light with a single polarization component, light polarized differently than what is being filtered out gets through, the light that gets through is your image.
 
If a scene is illuminated with light from multiple sources such as the sun as the primary source with one polarization plus light from some reflective object with a polarization different than the primary such as a nearby body of water, you can only filter one polarization or the other, not both.
 
Changing your angle of view of a scene can sometimes (don't count on it though) offer a view where the planes of polarization from two sources are aligned, then you can filter both.
Of course changing the angle of view well necessitate a change of position, changing angle and position will change the composition.
 
Might be that a ND filter or a graduated ND on camera or in post will offer the scene enhancement you seek.
Note that polarizer effects cannot be duplicated in post.

....the bloating software that goes with Windows......
There's a misconception.
Windows does not include bloatware, never has. If you were to install Windows from scratch, you'd see that there is very little software installed.
You'll get Paint, NotePad, WordPad, a photo viewer, Internet Explorer, some basic utilities and a few simple games.

Whatever bloatware you see on Windows boxes is installed by the device's manufacturer like HP, Dell, whoever, it's not Microsoft's doing or fault.

EOS Bodies - For Stills / Re: Card images failed transfer error on 5d3

As for the iBashing, I have been leaning towards swapping the iPad for a Samsung because of the remote control options you gain. But it still wont take a CF card directly I believe. A USB connection is also possible with an iPad for image transfer. It is however terribly slow......
A brief primer about USB Host and android......

Most somewhat recent android devices support connections via USB Host (also known as USB OTG, On The Go).
OTG connectors are standard USB Micro-B plugs with the normally unused 5th pin connected to ground.
In use, OTG allows many (most or all? dunno) USB devices to connect to an android's Micro-B USB connection and operate (as much as possible) just like they do when connected to a PC's USB port.
Just for grins and the experience, I've connected a USB keyboard and a USB mouse to my androids and they worked just fine even if rather pointless. Tried my xrite color calibrator, it connected and showed up just fine but is a model incompatible with my android software and hardware.
I regularly use my OTG adapter to connect a thumb drive or my camera for file transfers to and from my androids.

OTG connection is also fast and solid when tethering to android with the DSLR Controller app.
I've used the OTG adapter to transfer using a card reader, plug and play.
Here's a google for OTG adapters
https://www.google.com/#safe=off&q=usb%20otg%20adapter

I use a short cable dongle thingy that has a 5th pin configured Micro-B USB male on one end, a standard USB female receptacle on the other.
There are now OTG capable thumb drives readily available on the market that plug and play.
 
If your iThings support USB Host, you may be good to go for file transferring IF no additional software is needed for Canon connections.
I wrote IF because on WIN 7 and earlier (don't know about WIN 8 ) , Canons don't just plug and play as removable drives as some other brand cameras such as Nikon and Olympus do, drivers that install with programs such as DPP or Lightroom are required. Being an iAvoider, I've no idea how iThings handle connected Canons.

Regarding switching to a Samsung tablet, slow down a little bit and spend some quality time comparing specs, specifically screen/display specs.
Not saying I'm Samy averse, I have a Samy phone that I love/hate enough that I want a newer model.
When it came time for a tablet for use specifically as a Canon accessory, I chose an ASUS.
As the market has certainly changed since my purchases, I suggest you do your own research, ASUS may not still be the brand I'd choose for a tab.

B&H and NewEgg are two good places to start researching, good choices for purchasing too.
I especially like browsing NewEgg, on the specifications tab of many product pages is often a link direct to the manufacturer's product page

USD $8 for DSLR Controller
https://play.google.com/store/apps/details?id=eu.chainfire.dslrcontroller
Just get and install this, it's the Bee's Knees for tether controlling your Canon.
I use it with both my Galaxy S4 and my 10" ASUS tablet.
10X live view zoom for focusing is marvelous, it'll do focus stacking, intervalometer, HDR bracketing, shutter count and lots lots more.
Didn't care much for it over WiFi to my 6D on the Galaxy, basically useless.
Laggy but useful on the ASUS over WiFi.
Tethered via a USB Host (also known as USB OTG, On The Go) it's rather responsive, you'll likely find many other uses for a USB Host adapter cable.
Support is sketchy, no matter, the app is basically self explanatory, connect it up and poke around.
On the standard 1-10 scale I rate it about a trigazillion, just get it.
Since tethering with DSLR controller, I can't stand to even think about Canon's free EOS Remote android app nor DPP on Windows nor tethering via Lightroom on Windows.
Seriously, get this. But get a USB host adapter first.

From what I gather, Helicon Focus has similar capabilities as DSLR controller, but they tease you with free, then want USD $40, $48 or $75 for an unlimited license. Haven't tried it, doubt I will since DSLR Controller is so awesome.

USD $5 for The Photographer's Ephemeris
https://play.google.com/store/apps/details?id=com.crookneckconsulting.tpeandroid
Sunrise, sunset, moon rise, moon set times and angles for anywhere, anytime. Plan your landscape excursions with this, then check the weather report.
Interface on a phone I'd call tight due to screen size, still, it's workable and very informative
----

If your phone has IR,
DSLR Remote, free
https://play.google.com/store/apps/details?id=de.dslrremote
is a nice little substitute for the small, push button IR remote controllers available for most camera brands.
It's not bad, I've no complaints, a very simple app, efficient at its rather simple task.

Photo Mate R2 is a USD $9.49 purchase, it's a RAW converter for Android.
It's on my wish list, but I don't really have any interest working on RAWs on Android when I've got a rather powerful Windows 7 PC I built expressly with Lightroom in mind.
No experience with it though it does sound intriguing.
Claims to be able to "Calibrate your tablet display within the app" which sounds plenty trick, then I look at my PC and realize I'm just not going there on my tablet.
----

Canon's own EOS Remote is free, um, you get what you pay for. I'm not even going to bother about a link for it. It should be or maybe could be what DSLR Controller is but it's not even close.

To me, the concept looks like an invitation to get seriously involved in 3D printing, roll your own body, attach lens and back according to your design intent.

........transfer images from cf to sd in camera.....

The trouble is that when i am on location with my ipad, i have no way of reviewing the images on a larger screen. The ipad only takes sd, and i only shoot to cf......
At the risk of coming off as an iBasher, use an android tablet with DSLR Controller installed.
There'll then be no need for in camera file juggling, you can view photos stored on the camera directly on the android device's screen and/or copy files individually or in batches onto the android, with an OTG adapter, copy from android to any USB thumb drive, card reader or whatever.
