You're missing the point.

There was nothing in my post that indicated that I missed the point.  I was actually supporting your position, just from a system agnostic position.  :D

The fanboys, as I mentioned in my post, are those people who believe that a system they like must be not only the best system but the best system for other people.  Again, I was agreeing with you.

The best camera system is the one that works best for the individual.

Agreed.

BTW, I've not found too many fanboys here (which is the beauty of this site). There is general consensus that while Canon could get better at certain aspects (especially at you-know-what) of their cameras, most users don't find these issues limiting their photography. Trouble arises when people advocating another brand doesn't merely have an opinion, he has to beat everyone over the head with it.

The way some people argue on these forums, you would have to believe that Canon gear is trash and everyone needs a D810 and the 12-24 for getting a half decent picture of a doorknob that you need to push by 5 stops to get right ... Ugh ... and I mean Ughhh  :P

All equipment has limits, if you push it past those limits then it will fail.
This is true of other bodies and sensors as well.
No matter which body or manufacture you are using you should always take the DR in to account, none have enough range.
The best claim you could make here is that you do not have to discard as many shots with the other camera due to your poor craftsmanship.

But you give a bad example, it is bad because you pushed the lens and body beyond its limits. It was the combination of the body and lens not just the sensor.

A good example is a comparison of two identical shots taken with the same exact lens in the exact same situation.
Posts an example like this and we have something to discuss other than your skill level with a shot that you failed.

This is all too true.

On an aside, why would some continue to shoot with Canon gear if they hate it so much, if not hate it, find it too limiting. If they have switched to Nikon, you've obviously moved on, why complain about it on a Canon site?

Aberrations are caused by the lens. If a lens is producing (let's say) 3 pixel wide aberration on 20mp FF sensor, then the same lens will produce 5 pixels wide aberration on 20mp APS-C sensor just because those pixels are 1.6x smaller and denser. Simple math here.

Thanks

I do see a lot of younger people who eschew wearing a watch.  That would drive me nuts.  I even sleep with my watch on my wrist. It is probably a generational thing.

So camera manufacturers worry about cell phones taking the place of cameras.  I wonder if watch manufacturers are experiencing the same thing?

Younger is a relative term. I've worn a watch since childhood only to stop wearing it about 4 years back. I've been checking time on the cellphone ever since. Times change  :)

Nevertheless, cellphones have eaten up a large chunk of the P&S sales. To the generation that is "younger" to me, it's all about pushing the output on the internet. Even if the images look like they have suffered radiation damage are posted on FB and other social networking sites. A P&S doesn't make sense for a large part of the crowd.

I hope I'm not high jacking this thread ... It's gone way too scientific for me to comprehend fully despite trawling tHrough the posts.

Would it be a reasonable conclusion to draw that at low ISO (100-400), the difference between the APS-C and the FF is negligible, thereby meaning that the reach benefit could be satisfactorily obtained at the low ISOs?

There is always a difference. It may only be negligible for those who don't care.

Thanks. What differences would be obvious and what would be the ones you would look for? Again, I'm talking only of low ISO.

Sharpness, contrast, aberrations.

Hmm ... so basically sharpness and contrast are the obvious ones and the aberrations would be the one you would look for. Thanks for this.

To my mind sharpness has been relative, depending more on the available light and the focusing. Why the FF should be sharper is something I've not really understood.

BTW, wouldn't the aberrations be caused by the lens instead of the camera body?

Canon is looking to shut up the "Canon isn't innovating" brigade  ;D

The last line takes the cake though -

And so on the products that you intend to produce a new fun as an interchangeable lens system, please keep looking forward to it.

Now, I know that it is a translation but I couldn't resist.

Good to hear a sane voice. I'm tired of people telling me how bad my gear is.

EOS Bodies / Re: 7D2 and EF 24 - 105 F4 L IS USM
« on: September 22, 2014, 12:03:10 PM »
Why not get the 17-55? Used, if possible. This lens retains substantial value and is excellent for shooting on the APS-C.

The 24-105 on an APS-C is an oddball focal length and it is f/4 as well. The one stop ISO penalty is pretty heavy - I'm thinking of the difference between ISO 3200 and 1600 and then between 1600 and 800.

I'm excited about the 7DII for the AF and the 10fps. if Canon has taken care of the banding, I'm getting one.

Oh, and here's yet another wedding image I was processing from my 5D3 that I decided to throw out b/c by the time I corrected the 3EV vignetting of my 24/1.4 and then added 1.5 stops (b/c I underexposed by 1.5 EV to save the sky/clouds above my subjects), I had this wonder junk overlaid over my image

Maybe you should learn to convert and process your files properly.

I always thought wedding photographers make use of reflectors to avoid such classic lighting problems? That was what my wedding photographer did to get a beautifully exposed shot with the sunburst and blue sky behind us. Oh, he was using the Canon 5D classic.

Oh, here is another example: http://www.mattgranger.com/light. Matt has mostly Nikon gear.  ;)

You are absolutely right, except that generally those here suggesting the Exmor tech can do a better job don't want to be bothered with fill, they want to be able to use every ounce of the extensive latitude in the Nikon file.

They will of course will be lifting data that has recorded virtually no light, so the photographer using 'old' tech such as a 5D or D200 and sound technique will produce a much higher quality image.

So what happens if you use sound technique with both Canon and Nikon ? You get pretty much the same image. A well lit and correctly exposed image will always triumph over the same one which has been poorly lit and under exposed.

Sensible post alert! You talk too much sense Sporgon and it's not likely to go down well with the ABC crowd.

Photography is all about light and handling thereof. Light is "lightly" tossed aside by the people giving examples of the benefits of an exxmor sensor.

I can understand someone complaining about DR for landscapes (not taking into account that DR in most landscapes will exceed even the what the exxmor provides). But why someone shooting in a controlled environment should complain about DR is beyond comprehension.

Being a hobbyist, I've used WiFi considerably on the 6D instead of the GPS. Too many of my family and friends want their photos ASAP and the 6D with the EOS-Remote has been upto scratch for this purpose.

The GPS has come in handy a few times I was shooting out in the wild, but WiFi has been more useful to me.

Lenses / Re: Lens price drops around the world
« on: September 09, 2014, 10:55:21 PM »
From what i am hearing, it is US only...  but other countries have dropped a bit.  I just hope that it drops a bit here in India...  I've been saving a long time for my 500 f/4 and would be miffed to buy and then it loose value right away!

Canon India did drop prices a couple of months back. The lenses included in the recent drop were 180 macro, 70-200 II, both L TSEs, 85L and the 300 2.8 II L. The price drop was quite steep, approximately 14% or so.

The superteles. Including the 500 II are already reasonably priced in India. The 500 II can be got for INR 550K. This is slightly less than, or roughly equal to the US price which I believe, underwent a drop recently.
