EDIT:
Hmmm 15-85mm? It costs around 800$(750euro) Wouldn't there be an L lens in that price range? *Not planning to buy one soon, just curious.*

The 17-55mm f/2.8 IS is even more expensive.  IMO, the 17-55mm is the best general purpose zoom for APS-C, and the 15-85mm is a close second.  Both lenses are of L-series optical quality (as is the 10-22mm), but not build quality. Compared to the 24-105L or 17-40L, those three EF-S lenses (17-55, 15-85, 10-22) actually deliver better IQ than the 24-105 and 17-40 L lenses on the same APS-C camera (and the 17-55 outperforms the 16-35L II on APS-C, I know from personal experience).   

The 17-40mm is sort of 'general purpose' (a little short on the long end) on APS-C, the 24-105 isn't in that category (it gives the FF-equivalent AoV of 38-168mm on APS-C, meaning it's normal to tele, and a general purpose zoom should cover wide to short tele).

The only times I'd recommend one of the L lenses over the 17-55 or 15-85 are if you have a 7D (decent weather sealing) and need a sealed lens to use in inclement weather, or if you have both FF and APS-C or are getting a FF in the very near future (weeks/months, not years).

EOS Bodies - For Stills / Re: 1DX "Caution 02" Warnings AND Filthy Sensor.

Geez, people - RTFM.

I feel like Bill Murray's character in Scrooged - "Scare the Dickens out of people...Nobody gets me."

The email said that the sensors have been sealed to the filter in soem way shape or form for awhile, but just wondering how a company like lifepixel can replace just the sensor filter if it's sealed to the sensor itself? If they can do this, why can't canon replace just the sensor filter alone?


The 'filter' is actually several layers thick.  The horizontal layer of the AA filter, the 1/4-wave plate (what Canon calls the 'phaser layer') and the IR cut filter are bonded together, and this assembly is what vibrates for the 'self-cleaning sensor'.  It's the surface of this outer stack that you're cleaning when you 'clean the sensor'.  The vertical layer of the AA filter is bonded to the sensor itself (well, on top of the microlens array, which sits on top of the Bayer mask, which sits on top of the sensor).  Lifepixel et al., aren't replacing the whole filter, just the part of the filter that's separate from the sensor itself.

I can say that when I hold a 5DII shutter button for 2 s, I get 8 images with at best 3-4 in perfect focus. Holding a 7D shutter for 2 s gives me 16 images with 12-14 in crisp focus. Holding the 1D X shutter button for 2 s, I get 24 images with 23-24 perfectly focused.  Means triage takes more time...sacrifices must be made, I suppose...   :P

The combo will be f/5.6 and will AF on all Canon dSLRs.

Geez, people - RTFM. There's an entire section on the 'randomly distributed narrow-aperture diffraction test pattern'.  Just look it up, and also note the part about extended use as a healing brush calibration tool.  Here Canon gives you this great straight-from-the-factory feature, and they don't even charge extra for it...and all you do is whine.

 :P

FWIW, I removed my 'features' with a Visible Dust Arctic Butterfly 724 Super Bright.

Lenses / Re: Best Value "Normal" Lens for 6d?
« on: December 02, 2012, 05:02:00 PM »
Latest sigma 35mm f1.4 received good feedbacks.

But...on a 6D, that's a wide angle lens, not a normal lens.

Lighting / Re: ST-E3-RT and 600EX-RT to trigger 580EXii ?
« on: December 02, 2012, 04:16:51 PM »
It would...if you replaced your 580s with 600s (and I'm sure that's what Canon wants you to do).  I expect that there will be a 430-replacement that's an -RT version (likely slave only).  Then, at some point in the future (likely when 600 and 4xx -RT sales wane), Canon will release an -RT receiver-only with a hotshoe for older flashes.  Yongnuo may beat them to the latter.

Just to add - if you've got the budget for the 60D, 18-135 kit, and 50/1.4, you might still be better off getting the 50/1.8...and a 430EX II.  Yes, the 60D has a built-in flash...but nothing says point-and-shoot snapshot like the popup flash. It's great for fill light outdoors, but as a main flash indoors, a 430EX II bounced off the ceiling will look a lot better.

So what do they make better outside the af department?

Oh, let's see...faster frame rates, better metering (1D X vs. D4), a radio-triggered flash system, better real-world high ISO performance...I could go on, but I'm growing bored with feeding this particular troll.

DSLR is a system. So you need to look at is as system: lens performance, color redition, AF accuracy and speed, ergonomics etc. You can not just single out pixel count, noise level and say who is more advance in technoloy.

Well, of course you can. I mean, if that's not what the Internet is for, then what good is it?!?   ::)

I got a little confused here. You praised the 50/1.4 at almost all the questions. but still pointed me back at the kit lens? And i've heard that the it's better to get the 1.4 compared to the 1.8 since it only has a bit of difference in price.

Well, yes...that's exactly what I did.  The best choice would be to get the 18-135 and the 50/1.4. But I wasn't sure that was viable from a cost standpoint.  Even better would be the 15-85mm lens and the 50/1.4. Plus a good tripod for nightscapes.  Or the 5DIII and several L lenses. Just stop me when the cost gets too high... ;)

My point was that the 18-135 + 50/1.8 is in the price range under discussion (a little less than the 60D + 50/1.4, I believe), not a couple hundred € extra.

Here's the thing - the 50/1.4 may offer slightly better IQ, but how much will that help if you hit the wall of the room before you can back up far enough to frame your shot?

Since you're talking about an APS-C camera, having just a 50mm lens means your only lens behaves as a short telephoto lens.  Now, if you stated you were getting this setup solely to shoot portraits, I'd say the 60D + 50/1.4 would be great. But for, "indoor stuff/landscapes/nightscapes/people (and) street," if you're going to have one lens, a zoom is a better choice.  A normal prime would possibly be ok (like a Sigma 30/1.4).  But not a short tele prime, IMO.

I think he means Canon is behind with their (crop sensor) technology,

Ahhhh. Next time I'm in the market for a naked piece of silicon imaged as a CMOS image sensor, I'll keep that in mind.  Usually, though, I prefer to buy cameras, not sensors.  All that other technology wrapped around the sensor is sort of important to me.

I never meant that they are behind sales whise. But technology whise.

For anyone who believes technology trumps sales, how many Betamax video tapes did you buy?  That was a demonstrably better technology than VHS.  Who won? 

And with that blanket 'Canon is behind' statement, you've brought us right back to where the thread started. Troll-ville.

« on: December 02, 2012, 02:57:48 PM »
Just like Highlander (with apologies for the bad movie reference), "There can be only one."  There's one master, everything else is a slave. If the 600 is a slave (ST-E3 as master), it can't trigger a 580.

But, you mentioned not needing automatic metering.  In that case, why not just a set of 'dumb' RF triggers?  Yongnuo, Cactus, etc., would all work.

The ST-E3-RT has only a radio transmitter.  The 580 has only an optical receiver. The 600 has optical and radio transmission and reception.

An ST-E2 could trigger both the 580s and the 600, optically.

Subjective and bias.

Yes, now you're getting the point.  Opinions on Internet forums - this forum and others, your opinions and mine - are just that: subjective and biased.  That's why I brought up sales figures, which are objective.  One person may fervently believe that Nikon is better than Canon, while another rabidly believes the opposite.  But in aggregate, the data on dSLR market share indicate that more people have bought Canon dSLRs than Nikon dSLRs, consistently for the past several years.  Is Canon better? That's subjective. But the fact that Canon has outsold Nikon is an objective fact. I know what conclusion I draw from that fact...
