Wait, there is a MASSIVE difference in image quality between the 5DII and 5DII?! Since when??

Yes the 5DIII has improvements across all features (mostly the focusing system), but I don't know if image quality is really one that is massively changed. Used right, the 5DII has fantastic image quality.

When does diffraction kick in on a 50mp 35mm sensor?! How would this be good for landscapes or studio shots where you stop down? Wouldn't scaling up a lower mp shot probably look the same?

Diffraction is always present.  So I don't know what "kicks in" means.

These would be about 4 micron pixels.  Here's a chart for how diffraction affects MTF.

I meant "kick-in" like when does diffraction softening become so much that we hit the point of diminishing returns? There has to be a point where just cramming more pixels on a sensor is not going to help right?

I would love a higher res 35mm digital camera from Canon as I shoot small products (like makeup), and need to blow them up to poster sizes, so I'm all for it.

I'm not a tech guy, so I'm truly asking.

I love throwing my 40mm 2.8 in a pocket when I go out with just a 70-200 mounted to a FF body. That way IF I need something wider I'm not stuck.

I can totally see this lens filling the same hole with my 7D and 70-200.

They take up no space, cost very little and have great optics.

There is a place for that.

Does anyone remember any time in the past there was a discount on a lens even before it started shipping?

It's not a specific discount for this lens. I believe it just falls in with the "Spend more save more" promo. So you save 100 on purchases over 1k.

I think Canon satisfies photographers. I think the majority of complaints come from consumers that are way more interested in the latest and greatest gear and technology, and like the science of the technology that goes into making cameras and lenses.

But go over to Nikon Rumors and you will see endless complaints about Nikon not listening to their forum experts and how all every Nikon shooter ever wanted was a "true" D700 replacement and a D300 replacement... Basically people will just complain over what they dont have.

I want a Rebel with a ff sensor that is totally plastic, with a plastic mount (like the Rebel G). Kitted with a new 50mm f/1.8 STM with a plastic mount. 3 AF points. Mad small & cheap yo.

Can't it be both? I saw that the new Sigma incorporates them both.

Hey guys,

Will I get kicked out of the CR club if I admit that I actually am still satisfied with the images I can create with my 7D and 5DmkII?

Am I doing something wrong?

Just a heads up, but there are a LOT of threads on CR these days about Sensors, Sony and DRzzzzzzzzzz...

Lenses / Re: EF 24-70mm f/4 L IS - Discontinued?
« on: November 01, 2014, 11:48:19 AM »
It was to expensive at launch.  I still think that it will become the successor to the 24-105L.  The 28-135 STM is the replacement for old 28-135 USM.  When stock of the 24-105L parts or contracts to build parts run low I expect it to be discontented.  The 24-75 f/4 L IS will then be sold as an optional kit lens. 

Quite often stores decide what they will carry just because it is discontinued at a store does not mean they will no longer be sold elsewhere in Canada.  They may have decided to no longer carry them because they cannot sell enough. 

Lets face it the 24-75 f/2.8 IS II has a lager audience than the 24-75 f/4 IS.  Many buyers of the 24-75 II are upgraders from either the mark I or the 24-105L.  If I owned ether of the lens I would not be looking at the 24-75 f/4 IS.  The 24-105 f4 is still cheaper in may markets and has a better range. 

I expect that a full frame upgrade will include on sensor phase detection and video features similar to the 70D.  The 28-135 STM will likely be a kit lens.  Who knows this camera could be the 5D IV, 6D II, or some full frame rebel for all I know.   I halfway expect a Full frame rebel before the 6D II.

There are so many things wrong with this post. You should proofread before posting.

I'd guess this lens will end up the standard kit lens after the older 24-105 is discontinued.

I don't think you'll see 1300 for a while. The 7D kept it's price up for a very long time. I can see it hitting more like 1499 down the line. Then you could hit 1300 as a refurb sale.

but it doesn’t really plug any holes in the maker’s range.

Man, what do those guys think...

The Canon EF-S 10-18 f/4.5-5.6 IS STM is a 300€/$ lens that allows beginners and people with a normal budget to get into UWA.
I believe this is a really clever addition in Canons lineup meant for those double zoom kit buyers to at least buy a third lens and then get hooked. And it is small and light. And it will sell well.

I actually think this lens is really awesome. It's super light, cheap, and it's image quality is great!
Where it also has value is for people that don't really shoot this wide. Like me. I shoot FF and crop, but had no desire to drop a ton of cash on a lens that I'd rarely use. This lens fills that hole too.
