On Canon EF 24-70mm f/4L IS USM Preview preview (127 comments in total)
In reply to:

tongki: this is totally backward,
Canon already has EF 24-105mm f/4 and now provide EF 24-70mm f/4,
and we don't need stupid IS on wide lenses !!!

it really slowing it down !!!
I don't like using IS on wide lenses, that is stupid idea !

Go and buy yourself an EF 24-70 f/2.8 L II - what's the problem?

Canon is crazy! Nearly same price (in numbers) i Dollars, Pounds and Euros??? These three currencies are not equal value! If US price i 1500 Dollars, then i should cost roughly 1200 Euros and 900 Pounds.

In reply to:

Kinematic Digit: I wonder if this will include the illumination firmware update that the 1Dx now has.

Great news but wow, that's a long wait from this announcement. I'm a bit confused as why it's that long. They obviously know it can be done, and it's just a matter of coding and testing. At the most 2 months tops? Why do we need to even know about this if they can't get it to market in a shorter time frame.

Maybe the AF illumination will come sooner that this huge upgrade.

Denton Taylor: Hopefully 5Dmkiii comes right behind...

Yes, yes. I am aware of this camera, but I am talking about the digital era (1D class) of EOS system.

I think that the illumination wil make its way to next 5D Mark III firmware for sure.
But the f/8 AF? It is possible for sure - it shares the same AF sensor. But will Canon do this? That is a big question. The f/8 has always been a privilege of 1D class. But on the other hand, the biggest rival D800 can focus up to f/8 so it would make sense to put this feature into 5D Mark III firmware.

Nice girl with beautiful eyes. Left upper side (hair) could use a littlebit of fill-in flash or other light source.

Like this shot. Also have one of 1 month old baby here in contest ;-)

Canon must be under heavy pressure. I cannot explain the third fail in this year otherwise. 5D Mark III light leaks, 650D grip vanishes color, 40mm STM can't be touched. What else? Probably 1D X will melt when exposed to direct sunlinght or somethig like that :)

And now someone say that Mark II isn't able to focus using outer AF points! Although Mark III is better.

In reply to:

birdbrain: So according to these tests the 7D's AF is not that good then?

Read the comments. He says that it might be that you have to learn with it. But so you have to with 5DM3.
I own both of them and I can say that 7D is much more reliable in focus terms than 5DM2 (which I also owned). Even the graph shows something different. Maybe bad sample. 7D surely isn't worst of them all as shown by the graph.

In reply to:

mantra: Hi
great article!
but may i ask a question about Phase-detection autofocus ?
seening the new trend of the mirrorless camera ,i'm confused by the "Phase-detection autofocus"

is the servo mode? the tracking mode ? or the sensor cmos focus mode?

thanks

Hi mantra!
You have to read all articles related to AF if you don't understand the basics. Especially this http://www.lensrentals.com/blog/2010/07/how-autofocus-often-works
Mirrorless cameras basically do not have phase detection, they are contrast-based. The new Canon EOS M has hybrid sensor but it seems it uses phase detection only during movie on-the-fly focusing.

On Canon issues allergy warning for EOS 650D/Rebel T4i article (176 comments in total)
In reply to:

ericsan: What a bad born camera !!...
Instead of launching new rebel models every year with minor improvements from one model to the other, Canon would better concentrate on real improvements and launch fewer models...
I'm happy with my T2i and will wait to replace it at least until the T5i arrives if there is no bug...
Cheers !

I know. But nevertheless, it was a fault.
I had 400D, 40D, now 7D & 5D Mk II.... no issues so far. And this year? 5D Mk III - light leak, 650D - allergic grip.
Something's wrong.

650D is not the first "bad born" camera made by Canon this year. Their nearly-flagship 5D Mark III came out with the light leak issue that was spotted about one month after official retail release. But the light leak couldn't harm yout health at least ;-)

On Canon significantly improves EOS 7D with firmware v2 article (296 comments in total)
In reply to:

MediaDigitalVideo: I think the EOS 7D features where limited by software. As some people also suggest a lineup model for 7D won't come soon. I think that too. Love my 7D. Will I ever use my 5D Mk II ?

I think you will ;-) I also have 5D Mark II and 7D together. I still think about replacing Mark II with Mark III. But is the price of the upgrade (used Mk II selling price is very low now because "everyone" upgrades) worth it? Now I say NO. I will keep 7D for action shots, where I also can use 1.6 crop factor. And the Mark II is still great for studio portrait shots and landscape. And for such photos I do not need the AF of Mark III. BTW image quality of Mark III JPEGs really sucks. I know that many users will never shoot JPEGs with Mark III but nowadays I do so with Mark II and they are perfect usable... sharp, crisp, vibrant...

Great to see lots of upgrades for my 7D! But one thing would make me more happy. Auto ISO in manual mode on 5D Mark II. Technically no problem - DiGiC IV is capable of it. It's only o SW problem. I can't understand, why auto ISO i M is locked on ISO 400. It's useless then.
But I know they will never do because Canon has Mark III nowadays and Mark II is senteced to death.
