EOS Bodies / Re: *UPDATE* A Bit of EOS 70D Info [CR1-CR2]
« on: April 16, 2013, 01:10:34 PM »
So you think that 61 point autofocus is important on a 1Dx, but irrelavant on a 70D ??? The nice thing about Nikon is that they treat all their customers with respect. Nikon has no second class citizens when it come to autofocus and metering.

In a marketing driven world, having lesser specifications won't win the sales war.

So why not pay your money (or not) and take your choice, instead of constantly proclaiming Nikon's superiority and more consumer friendly business ethic to the rest of us? As for your comment about specifications and the sales war, are Canon losing market share? If you don't want to shoot Canon, no problem, I just wonder why you continue to hang around on a Canon forum and tell us all about it.

And, FYI, I won't be upgrading my 7D until Canon offers a genuine upgrade, so I'm not defending their strategy, I'm just tired of the same old commentators with nothing new to say that seem to surface every time Canon -RUMOURS- (not even announces) a product.

Third Party Manufacturers / Re: "I am boycotting Nikon" campaign

I'm boycotting all these imaging companies. They make infernal machines that steal your soul!

My belief is that corporations have essentially completed their takeover of the world. They will make minor adjustments responding to niggling little complaints like this to keep sales at full tilt. Beyond that, we and they are on a path to destroy this planet. Since I can't stop it, I plan to enjoy the ride into the pits of hell.

Ain't that the truth. Very true Sir, very eloquent.  :'(

Qwerty, if you're out there I have re-read your posts and the key points make sense to me, namely that the larger sensor will of course offer more resolution because of it's larger size and therefore greater line widths per picture height, and also because of the cropped sensor image requiring greater relative enlargement to appear at the same size of the full frame image- not to be confused with the total number of pixels, which, for example, comparing the 1DX and 7D might be similar, but the 7D's are crammed into a much smaller sensor. Of course I always knew the FF sensor would provide better IQ, due to it's larger surface area and consequently greater light gathering ability, it was just the difference in sharpness particularly apparent in TDP's sample crops that astounded me.

The other thing I think was confusing me was the units for resolution- lp/mm, which is independent of sensor size, and lp/ph, which is not.

Anyway, it makes more sense to me now, thanks again for taking the time.  :)

Ouch! That was a bit harsh wasn't it? It wasn't me that invented the 'Queen's English'!  ;)

It wasn't "I" (not "me" for us purists)

C'mon, let's keep it on topic here shall we?  ;)

Maybe there is room for a "Humour" section threads like that could be moved to.   


...and a section for threads where people put a 'u' in words like humor and color.  Oh, wait...we already have one:P


Ouch! That was a bit harsh wasn't it? It wasn't me that invented the 'Queen's English'!  ;)

If I was going to have a grudge, it would be because of something it them taking 4 tries to Canon's lens repair service to fix the IS in a 70-300 IS USM (non-L).

"Yeah we fixed it", "No you haven't, try again." "Fixed it this time.", "Put on a camera and it didn't work, try again." la la la

No, the point of me saying this is because lots of people are arguing that "Canon cameras sell well, so obviously 18MP is enough" or "... so obviously the DR isn't important." In a sense they're right, but it appears that it isn't the IQ that is selling the camera - it is the bells and whistles. When the reason for choosing a 650D over something else is the touch screen, then as long as the camera has enough pixels for facebook and WiFi to upload, well who cares about PASM, etc?

Ok, so you had poor service. I'm sorry that happenned, but that's not exclusive to Canon.

Personally, I welcome improvements to IQ and DR, as I'm sure many here do. The bells and whistles don't interest me either, but I accept that in todays social networking culture they will interest many, and Canon is going where it thinks the money is. That's business.

EOS Bodies / Re: Canon EOS 1DX Junk camera??
« on: April 11, 2013, 08:01:26 AM »
For F's sake, can you dummies stop replying to this guy!?? What is wrong with some of you people??? He is making a fool of the CR forum, and you idiots actually post a reply...? Nice going! No wonder there's some folks posting stuff like this here every now and then, cause there sure are are enough suckers with nothing better to do than to write the oh so valued opinion on matters Canon... Jeeeeez!!

Perhaps some of those who replied just wished to have a little fun, apparently in the same fashion as the O.P. Bit of humour isn't such a bad thing is it?!  :P

You're not listening (and/or perhaps you didn't properly comprehend what I wrote.)

All that mattered was that one camera had a touch screen and the other didn't. MP be damned.

Ok, I hold my hands up. I didn't properly comprehend what you wrote. However, your anti Canon stance on this forum frankly has become a tad tedious, and I don't think I speak solely for myself when I say that. I am not for a moment saying that we shouldn't complain or raise issue with things that we dislike about Canon cameras. But the manner of some of your postings suggests you have some grudge against Canon. Or am I again misunderstanding you?

No, she didn't care about picture quality. The 650D could have produced images half as good as the Nikon but the touch screen, well that's just like new phone that has a touch screen and "iPad" that has a touch screen, so why would anyone want one of those prehistoric things with knobs and stuff?

Has DxOMark quantified that the Canon images are only 50% as good as the Nikon?

145
Qwerty, thanks for taking the time and effort to respond! I will take a good long look at what you have written to try and understand better. I had previously assumed that the increased pixel density of the crop sensor camera was 'magnifying' any flaws of the lens, which is one of the points you make.

146
Further to this topic, I've checked some more of The Digital Picture's sample crops, this time for the 70-200 f4 L IS (a lens that I own): http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=404&Camera=736&Sample=0&FLI=3&API=2&LensComp=404&CameraComp=453&SampleComp=0&FLIComp=4&APIComp=2 compared on a 60D crop body and 1Ds mk III full frame body- the situation is the same, the full frame crop is sharper everywhere, and indeed, this seems to be a general thing- the same lens used on a FF body appears sharper than the same lens used on a crop body. In the comparison, the aperture is set at f5.6, so diffraction should not be having any effect on the crop sensor result. I understand that the full frame sensor will deliver more total resolution, and that the 1Ds III has 21.1 megapixels compared to the 60D's 18 but can somebody explain why the full frame crop is sharper everywhere? Surely it must be possible to achieve sharp results at a lower total resolution? If pixels are a dimensionless unit, then surely it cannot be because of the crop sensor image requiring more magnification to appear the same size as the full frame image. I apologise is this has been discussed before, but I'm really trying to understand the reasons for these differences and how much difference going full frame would make to me.

147
Its very difficult to design a ultra wide angle lens and get sharp undistorted edges, and still sell it at a popular price.  Most users of rebels would not consider a high price for a truly excellent lens.
The new15mm Zeiss is easily the best.

I quite agree that wide angles are one of the hardest lens groups to design, even more so for crop sensors, but what astounds me with The Digital Picture's sample crops is not just the difference in corner sharpness, it's everywhere- centre frame included! Could there be other factors influencing this?

148
I'm a hobbyist photographer who mainly shoots landscapes, and have been using a 7D for the last 3 years. My ultrawide landscape lens is the Canon EF-S 10-22, which does yield good results, but coupled with the pixel dense 7D does struggle with fine detail towards the corners when the files are viewed near to 100%. Whilst I always expected that going full frame would give benefits especially regarding landscape photography, and is something I intend to do in the medium term when i can afford it, I was quite amazed at the difference in sharpness comparing the sample crops on The Digital Picture: http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=271&Camera=736&Sample=0&FLI=0&API=3&LensComp=100&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=3
Looking at this comparison, with both lenses set to f8 and at their widest setting to provide a similar FOV in their respective formats, the EF-S 10-22 used on a 60D crop body @10mm appears very unsharp and with more visible CA than even the 17-40L ( itself not regarded as a stellar performer at the wide end on FF until considerably stopped down)  used on a 1Ds mk. III. Is this showing the limitations of ultrawide glass on pixel dense crop sensors or could it be partly down to a poor copy of the 10-22 being tested? This difference indicates that I would see a marked improvement in IQ by switching to a FF body, even using the 17-40, which I already own. Any thoughts/ input appreciated!

Dilbert, I'm genuinely interested. For somebody who obviously dislikes Canon and all it stands for, why are you still posting here? So you can educate newcomers to come towards the light (eg, Nikon) before they settle for any of Canon's rubbish?

No avatar or picture because I haven't found where to add it, or any of the other customisations like a signature bar, is this because so far I have only been accessing the forum on tablets, or is there a minimum number of contributions before I get this privilege?

The historic name for people from my location is Caulkhead the area is Isle of Wight southern England anyone else on here from there or are Devon and Cornwall as close as you get?
Am really enjoying the posts here, you all seem very friendly or at least tolerant as from the forums I haven't seen any real flaming or aggression which is cool.

Heh, regarding the flaming and aggression.... give it time! I'm from Exeter, Devon. You can customise your signature and avatar in the profile tab at the top of the screen and then the forum profile sub option on the drop down menu once you've racked up a few posts, not entirely sure of the exact number of posts required but certainly no more than 10.
