Third Party Manufacturers / Olympus OM-D E-M1 officially announced.

Not cheap, well featured.
OK, I'm waiting for DxOmark to test it. ;)
Some new glass looks promising too.
Likely will be a good successor to the 'M5

none of the CR domain code is slow,
it's just google (adsense and G+), twitter, facebook, (gurble?!?) and a smattering of other domains that get (multi-?) referred to by whatever I haven't had the patience to track.

By the time some of these things get resolved the sun has moved perceptibly across the sky when I try to access from work - I've had loads take nearly 3 minutes or even time out.
At home I'm on a feed that's got great burst BW and Mb+/s sustained thru-put.  Page loads reasonably well but all the non-CR domains are still fairly slow to load.

Yup, maybe a new adblock plugin is needed, and custom block everything else.  Hmmm... maybe my ISP is traffic-shaping some of that junk.

edit:  anyone else on this part of the continent having load speed issues? (AB, BC, WA, ID, MT, AK)
edit 2: yup, with some updated ad, script, and track blocker plugins CR front page loads super fast.

On tiny camera systems, with little in the way of a lens in front of the sensor, UV might be an issue.

What issue?  The sensors have a CFA, which does a pretty good job of filtering out UV, and an ok job of filtering IR (ok but not great, which is why there's an IR cut filter over the sensor).

YUP.  Non issue.

It's been happening a while but seems to be getting even worse lately, opening the front page of this site can take a very long time.
from what I can tell, it often seems the holdup is google-analytics related code and waiting for social media sites to return data for their links (with counters?)
Seems at its worst during the day when all those over-used social media sites are very busy.

Once into the CR forum section, stuff loads pretty quickly, even with graphics.

I doubt any of this is going away... I'll either be skipping the front page or looking for a browser plugin to block all that 3rd party code from trying to load.

In cell phone sensors they are getting to the point that removal of the UV filter likely makes sense as well because of pixel pitch. 

How would removal of the UV filter based on small pixel pitch make sense?  UV wavelengths are shorter than visible light.  Perhaps you meant the IR cut filter?

On tiny camera systems, with little in the way of a lens in front of the sensor, UV might be an issue.
But since glass already attenuates a great deal of UV, specifically filtering for it may become unnecessary.

Add to that large, multi-element lenses and their intrinsic coatings bandpass, there's likely very little UVA reaching a sensor, much less shorter wavelengths.

You are still gathering that heat. It will either be directly in the sensor itself, or a fraction of a millimeter above it. One way or another, the ambient temperature of the sensor is going to increase, so why put in an unnecessary filter?
IR certainly an issue for now, but not likely for causing much in the way of heat gain unless aiming at some well lit scenes without a shutter in the way.  The electronics and remainder of the system packaging is likely to radiate more heat to the sensor than what comes thru a small aperture.

I can't wait for Nikon to go out of business. Their sensors are worse in every way that matters, their bodies are low quality and the controls make no sense and their pathetic excuses for lenses  perform worse than coke bottles.

I have to try hard not to laugh out loud every time I see a moron who spent thousands on a "pro" Nikon body. Pathetic. The 70D wipes the floor with everything Nikon can put out at any price level.

Well, I think we can boil this down to a single word:


That troll is a lovely single-shot HDR exposure capturing him in action and clearly showing us his dingy candle-lit domain while retaining excellent fidelity in the outdoor scene visible beyond his entrance.  No obvious banding or read noise problems so must be an image created with Exmor-based tools.

Lighting / Re: Thinking of buying a Light Meter

99% of hobby photographers, even very serious very capable hobby photographers have no real need for a light meter.
I've got a pair of higher end older Sekonics.  They're wonderful.
They spend most of their life in a drawer, with the battery removed - cuz it seems to run down if I leave it installed.
Occasionally use them for setting up complex strobe lighting or as a comparison tool when I need to check my camera metering.

Beyond that I have yet to see an example pair where the AA version couldn't be sharpened to look the same as the non-AA version. Perhaps someone could post such an example, I admit I haven't extensively tested this. But the couple times sample pairs were available a quick USM brought them even.

you need to try it and pixel-peep but the difference is there.
you can sharpen the AA version to be about like the non-AA version
But you can also sharpen the non-AA version to get wow-factor... at least in the center region with a good lens.
edit:  I rarely use USM for sharpening fine detail, it messes up edges with too much contrast/halo compared with other sharpening methods.

I love my d800e for that reason, the textural detail it can deliver is very impressive.

I also prefer my K-5 IIs for the same reason, AA-less 16MP crop body that delivers amazingly crisp detail.  I can see the difference when I go back and shoot blurred sensors; the pixel-level detail is not the same.
I haven't had a chance to shoot with the higher res D7100 yet.

Moire's not often been a problem, but false-color fine highlite details have been so I rarely use these cameras for shots with energetic moving water and other fine specular reflections.

70D has a bit better sensor performance than the 60D, it's pattern noise is negligible compared to both 60D

Are there any reviews on this yet? Of course the 70d is the better camera as it should be, but the 60d pattern noise was already lower than 7d and probably even 5d2 - and the one "lens cap" shot from 70d still showed the pattern, so I wonder if there's really any noticeable improvement.

don't know if there's any big site review yet, there's evaluation of it and I put up the samples in another thread here days ago.
started in the rumors section, unfortunately  OOPS/

70D's not perfect, but it's the best crop sensor from Canon since the 40D from what I can tell.  It's way less bandy than my 60D at lower ISOs.  It did seem to throw up a lot of extra noise with the main display ON tho.

besides everything else, 70D has a bit better sensor performance than the 60D, it's pattern noise is negligible compared to both 60D and 5d2.  5d2 IQ is only marginally better, if any, and, having shot with a (really bad example of a) 5d2, i'd opt for the 70D for better IQ and a ton of extra and even useful features.

I got a Fuji X-E1 on Friday and played with it over the weekend. I am really impressed. This is going to be my new travel camera for sure!

one of those, or possibly the non-optical VF cheaper model, is on my wish list yet too.

DxO reports what they measure, they're not really interpreting it for you.  Same lens can perform quite differently on different model bodies of same brand, that's what they're all about measuring.

only problem I have with them is their vague "scoring" which, in the case of lenses, actually includes a factor for the sensor noise of the camera it's mounting on?!?... WTH?!?

Meanwhile, convert your first lens link to a pair of 12MP cameras of the same era (D300s and 450D) and the comparison is very close.  FWIW.

So, those of you who have used both systems do you guys feel that Nikon cameras are designed and built keeping a smaller hand size as the target compared to comparable Canon cameras? I used the Nikon cameras of two of my friends (one D80 and the other was probably D90 or D7000) and found the hand grip feeling smaller/thinner than my 40D and 50D....... any opinion?

I've never picked up a Canon body that didn't feel OK to hold & use.
OTOH, I positively HATE the feel of Nikon's D7000 series and the D600 - I find them so unpleasant I skipped buying the economical D600 and grabbed another D800 instead.  Those slightly smaller/thinner grips give my hand a cramp in very short time where I can carry a d800 or smaller D5100 around for hours w-o a strap quite easily, even with large glass attached.

D800 is a larger body, my hands are small to mid-sized and the D800 is a very comfortable camera for me to use.
Also, the D5000 series cameras are very comfortable for me despite the small Rebel-ish size.  The proportioning and overall balance are more pleasant than the d7000/600 IMO.  All highly subjective, of course.

D90 is not bad for me but don't like it as much as d800's fit.

I'm still waiting to see if there's a high end cropper coming (D400 ?) to replace the aged D300/s but concerned it might feel too much like the 7000 series.  That will also be competing against a possible 7D Mk II for my uses.
The 7D was a really nice camera to use in all respects except, for me, it's IQ was inadequate for some of the shots I wanted it for.  I'm hoping 7D2 will continue the excellence and provide improved noise levels; even the 70D would be adequate but I won't be needing it until next summer so can wait.

More on ergos, I often shoot with a Pentax K52s, great little camera, feels lovely in my hand.
K-30 has that annoyingly deeper, thinner grip, not too unlike D7x00.  But not quite so bad that I didn't buy the K30... for $450 for a NIB camera with its capabilities I could put up with a bit of discomfort for the little time I'll be carrying it. :)

Over the next few days we may see a what the competition's gonna be offering to tempt our wallets.
Oly's new EM1 looks like a deliciously compact little MFT that could be even sweeter than the EM-5.
Sony may be courting phone-camera users with real optics add-ons.
Pentax is rumored to have some new toys for us too.
Fuji's likely up to something interesting again.

All these are very innovative but likely still to remain niche players compared to the Canon Juggernaut.. who may be finally intro'ing improved M models.  Almost seems like an anti-climactic finish if Canon doesn't have something meatier for a press release.

2013 is SUCH an interesting year for photo-tech.

These are all largely pointless debates...Nikon vs. Canon color depth bits, minute 1-2% differences in SNR, etc.

I agree with pretty much everything you've stated but the SNR differences are much greater than 1-2%.  They may be that at the highlites end but SNR difference is actually huge where it matters in post, on the dark end of the curve.
there's a good 2-4 stops difference between Canon and …everybody else at 0db SNR.
