That's a nice moral if you want to tell a completely different story from the one with which you started.

What does "mirrorless" have to do with my recommendation that Canon dumps their "crop-frame" system and concentrate exclusively on "full-frame" - mirrored and, if they so desire, mirrorless?

It is a fact that dSLRs outsell mirrorless by a very large margin.

So what does that prove? (But also read below.)

You stated that pretty much everyone who was going to switch to mirrorless has already done so.

So?

So unless you'd like to retract that statement, the moral of your original story is that MILCs have a very dismal future.

I am sorry, but how you came to that conclusion is for me a mystery.

However, if I understand you correctly, based on my typewriter analogy, DLSR's outsell "mirrorless" and thus "mirrorless" is doomed.

But if we push this interpretation of yours a tad further, then we see that "crop-frame" DSLR's outsell "full-frame" DSLR's. So does this mean that "full-frame" DSLR's are also doomed?

Why would you conclude everyone choosing between the 70D and 6D would choose the latter?

Perhaps because you said so?

You continue to misinterpret my statements, and now you're outright fabricating statements you're attributing to me.  Sorry, but your reading comprehension is abysmal and that makes any further discussion totally pointless.

When the heck did I say that?

You didn't say it.  If you're unfamiliar with the meaning of the word 'implication', I suggest looking it up in a dictionary or using Google.

[sarcasm]So the conclusion is that a "full-frame" camera with a mediocre, entry-level AF system trumps a "crop-frame" camera with a terrific, state-of-the-art AF system. Got it.[/sarcasm]

Trumps?  For some that is absolutely true (with no need for sarcasm), for others no.  Why would you conclude everyone choosing between the 70D and 6D would choose the latter?  Of course, you should keep in mind that the 6D is a modest upgrade to the 5DII, which was an extraordinarily popular camera despite having a glorified version of the AF system from the 20D (which soon made its way to the Rebel/xxxD line).


The moral of the story (regarding typewriters) is that one year you are on top of the world, selling thousands upon thousands of units, and the next year you sell nothing, and the year after that you file for bankruptcy. Good sales today doesn't necessarily mean good sales tomorrow.

That's a nice moral if you want to tell a completely different story from the one with which you started.  It is a fact that dSLRs outsell mirrorless by a very large margin.  You stated that pretty much everyone who was going to switch to mirrorless has already done so.  So unless you'd like to retract that statement, the moral of your original story is that MILCs have a very dismal future.

Considering the 7d II just out, I do not see such great improvements giving a wait of 5 years. Just the video part and a little on the high iso range, but for the rest? 2fps and 2MP more? Oh, I am impressed!

You don't see great improvement IN THE AREAS you want... but there are SUBSTANTIAL improvements.
...
You do not see 65 Cross Type AF Points up from 19 as a huge improvement?

Irrelevant to those who believe that sensor = camera.

Then those that say Canon isn't innovative will have to find some other area to whinge about.

I doubt that will be a problem, those folks can be very innovative themselves when coming up with new ways to bash Canon.   ::)

That's one reason, certainly.  Perhaps image quality doesn't matter to you.  It matters to me, as do better AF, frame rate, etc., which is why I own a 1D X. 

We are discussing why anyone would choose the 6D over the 70D, so throwing the best DSLR ever into the mix is out of bounds.

The reasons are obvious.  I gave one, there are others. 


I was merely attempting to facilitate your following your assertion to a logical conclusion, but apparently you are unable to do so.

But I did.

Sure you did – typewriters were your logical conclusion.   ::)

Lighting / Re: Review: Canon MR-14EX II Macro Ring Flash
« on: Today at 08:22:41 AM »
GN = 14.  As a regular flash, a 270EX II is more powerful and can be bounced. 

What sort of macro do you shoot?  The MR-14 provides rather flat lighting.  It's great for documentary shooting, medical images, etc., not as good for creative stuff.

Thanks Neuro - yes ideally a comparison with 300II. I have no reason to doubt you but have you seen any review or site that has actual examples so I can see with my own peepers what sort of difference we are talking about?

I haven't, and I doubt we will.  Best option may be to rent/borrow a 7DII and 1.4xIII and try it yourself.

9
Which 300mm? If you mean the 300/4L IS, I expect the 7DII + 1.4x would have an advantage.  If you mean the 300/2.8L IS II in your signature, I think the 5DIII + 2x would be better, although in truly reach limited situations the differences would be small.

What kind of people wonder around taking pictures in the dark with teleconverters?


Nikon's is more rewarding if you're using teleconverters with your lens or you're focusing in very low light situations (-3EV on the D750.)

If you put a 2x teleconverter onto a f/4 zoom lens then you're at f/8.0. Low light levels, at events, near dawn or dusk, etc.

-3 EV with an f/8 lens could mean, for example, a 0.5 s exposure at ISO 102400.  How rewarding do you think that would be at events or shooting at dawn or dusk?  Apparently you have no comprehension of the amount of light -3 EV represents.

That would be fine if AF was in some way linked to ISO, but other than its rating, it isn't - your camera's PDAF array isn't built into the sensor, so changing the ISO that you shoot at won't help your AF (and if you're using live view, the camera will increase ISO as required for contrast based AF.)

To put this in better context,  using an f/4.0 lens at ISO 100, EV-3 correlates to an exposure time of 2 minutes and EV-1 (which the 5D Mark II does) would get you 30 seconds. At dawn/dusk, I have so often found TTL autofocus to not work that I default to live view AF now (if not manual.)

For the curious, a full EV table can be found here:
http://en.wikipedia.org/wiki/Exposure_value

So yes, I know exactly how much light -3 EV represents (and have experience shooting in very low light conditions.)

Yes, I know how the PDAF system works. 

You mentioned events.  Do you shoot 30 s to 2 min exposures often when shooting events?  It's a red herring - people touting the supposed advantage conferred by -3 EV (over the 5DIII/1D X at -2 EV) with no idea how dark that really is relative to most shooting situations.

BTW, the 5DII's PDAF is spec'd to -0.5 EV, not -1 EV.

I was afraid I'd get asked that
Tonight I'm scrutinising a jar of garlic with the camera sitting on the table...  8)
Oh and the 2mm difference (at a guess) isn't every shot... 8 are fine, 2 are off... with miniscule differences between the great ones.

That's a lot of garlic!

Reasonable target, though.  I expect the variation you're seeing is normal.  But it likely wouldn't hurt to call Canon and ask.

12
At 2.8/24mm on the 24-70, 10 shots in One Shot, after racking each shot to macro I'm seeing maybe 2mm difference of the focal plane at a distance of 100cm. (Camera wasn't moving) Am I being stupid? Demanding too much? Maybe I've forgotten just how bad my kit lens with my 400D was 6 years ago and its long gone. I don't have anything to compare the 7DMKII + 24-70 to, except other lucky owners out there.

What are you focusing on for the above test?

There are nearly as many reasons people would choose the 6D over the 70D as there are people who make that choice.  I could produce a list of reasons, but they're not my reasons...

But if you must have a reason, try this for starters...

Just as I thought: the primary reason for picking the 6D over the 70D is the "full-frame" sensor; and not the better AF, better frame-rate, etc. which the 6D hasn't got. Simply and only the bigger size of the sensor.

That's one reason, certainly.  Perhaps image quality doesn't matter to you.  It matters to me, as do better AF, frame rate, etc., which is why I own a 1D X. 


They've already lost the mirrorless market ... almost everyone who wanted mirrorless has switched by now.

Really?  If so, then consider that dSLRs continue to outsell MILCs by a very large margin, and extrapolate from that the implication for the future of MILCs.

And typewriters outsold computers ... until the mid-1980's.

Again, you completely miss my point.  You're the one who asserted that almost everyone who wants mirrorless has switched.  I didn't say I agreed with that statement, in fact I implied the opposite.  I was merely attempting to facilitate your following your assertion to a logical conclusion, but apparently you are unable to do so.

Thank you for pointing outside of in certain select situations, such as sports and wildlife photography, there's no reason to buy Canon.

Good try.  Actually, pretty pathetic...but I thought I'd start by saying something nice.


Well consider that reviewers everywhere are now generally panning Canon when it comes to their DSLRs and especially the sensor.

Really?  Reviewers everywhere?  You need to read more widely.


I'd prefer a system which gave me the same AF performance with every lens because then I'm not faced with having to make any compromises.

Even if that AF performance was less accurate and precise than it could be with faster lenses?  That's a pretty big compromise you'd be making for that 'same AF performance'.  Oh, and speaking of same AF performance with every lens, every Canon lens that mounts directly on a Canon dSLR will autofocus.  Will every Nikon lens that mounts directly on a Nikon dSLR autofocus?  More compromises...


And I'd prefer my AF to work at -3EV rather than to have a select few AF sensors work better with f/2.8 or faster lenses.

A select few working better with f/2.8 lenses.  20 AF points working better with f/4 lenses.  As for -3 EV, do you often find yourself shooting with settings such as, for example, 1/15 s, f/2.8, ISO 102400?  In many cases, settings consistent with -3 EV do not produce usable images. 


But that's just me.

Yes, just you.  Someone who clearly has a poor grasp of facts where dSLRs and lenses are concerned.
