EOS Bodies / Re: A Little 1Ds Mark IV Info

« on: January 19, 2011, 07:48:18 AM »

Won't surprise me one bit.

From this site: http://www.mirrorlessrumors.com/exclusive-nikon-to-launch-a-mirrorless-system-in-april-with-sony-sensor/

"According to our veeeeeery good sources Nikon will unveil their new mirrorless system in April! Nikon developed a very advanced (and expensive) pro system not meant for the amateur market."

I suppose Canon will release something similar as it will help to staunch the bleeding in their market shares. Mirrorless systems is the way of the future, even Chuck Westfall acknowledged this in 2006 (one year before Olympus announced the world's first mirrorless interchangeable lens camera).

EOS Bodies / Re: The 60D Needs AF Microadjustment

« on: August 30, 2010, 08:37:06 PM »

The D90 does not have AF microadjustment so Canon figures the 60D does not need it too.

They fail to realize their (Canon's) QC is pretty awful.

They also fail to realize the D90 upgrade will FAR surpass the 60D in terms of specs.

Canon has been chasing after Nikon in the past few years. Considering how they use to lead the DSLR department with all their innovation and technology, it's a crying shame.

Now, they have Sony to contend with as well...

EOS Bodies / Re: Canon Announces EOS 60D

From dpreview..
AF microadjust:  No
What!!!??? Are you kidding me?
Comparing the 60D to the Nikon D90 replacement, the D7000, this is a real disappointment:
- 100% viewfinder
- dual memory cards
- 6-8fps
- 39 AF points
- mag body
- 25600 ISO

And worse still, the AWFUL price compared to Nikon's upcoming D7000 and Sony's A55.

My prediction: the 60D, like the 1000D, is gonna be a dead fish.

Oh, and where are 14-24 f/2.8 and 24-70 f/2.8 IS??? Canon photography department is heading towards a disastrous financial year.

but the Nikon PC-E Micro NIKKOR 85mm f/2.8D is a better lens, in many ways, than Canon TS-E 90 f2.8.

Do you have links that show this? I am intrigued and most surprised.

I agree Sony is very much lacking in their lens department, not just the tilt-shift stuff.

With those kind of specs, the 60D is already dead in the cradle even before it gets released. Just look at Sony's A55 and the upcoming Nikon D7000.

Canon has really lost it this time.

EOS Bodies / Re: EOS 2000D Book?

« on: August 24, 2010, 12:54:19 PM »

We often hear raging rumors before Sony and Nikon make their official announcements. And more often than not, these rumors turn out to be quite accurate.

In contrast, we hardly receive any solid rumors with regards to Canon's upcoming products.

Hopefully, the 60D and 2000D won't be a simple rehash of the 50D and 1000D respectively. Otherwise, Canon will lose their market share big time.

Whatever Canon is going to announce in the coming few weeks better be revolutionary like Sony's SLT A55. The Nikon D7000 and D3100 already seem so passe... True, the A55 may not possess any special technology but Sony has cleverly put together several old technologies (non-flipping partial mirror, EVF, articulate screen, good sensor) to produce a small, lightweight, cheap, all-round-capable camera. Now, if only Sony invests more effort in their lens department.

I love competition.

I currently own the XSi and 7D. I have decided that as long as Canon's EVIL cameras are compatible with EF-S and EF lenses, I shall replace my XSi with a Canon EVIL camera.

Looking at the leaked specs of the upcoming 16 MP Sony A55 (10 fps???) and 16 MP Nikon D95 (39 AF points???), it looks like the Canon 60D has some serious competition ahead. Canon better release something more than a 7D/50D rehash.

Are you referring to that G12 mock up with intolerably large lens? They are ruining the aesthetics of G-series should that design be true...

The 'fake' G12 picture shows focal length of 16.1-80.5 mm as compared to G11's 6.1-30.5 mm. This can only mean the G12 gets an increase in sensor size. I thought everyone has always been clamoring for larger sensor sizes. No?

I'll assume that that same sensor will be slightly improved a year in to it's existence much the same way nikons 12mp sensor got better and better in each generation.

Well, Nikon's D90/D5000 seems to have a 'better' imaging sensor than the D300 only because they resort to in-camera RAW NR which is easy to implement in slower (lower fps) cameras. BUT the NEWER D300s sensor is still very much like the D300.

Many people like the reduced weight of the Rebel bodies but complain about the small grip.

Now, Canon is releasing a relatively lightweight (hopefully) body with substantial grip, clearly taking a leaf from Nikon's wildly popular D90. And people are still whining.

Hey Woody,
I really would be interested in reading more, and seeing more comparisons on diffraction.  Everything I have read and seen says that it gets worse on dense sensors, but this is one of those things where I would love to be proven wrong.  It would make my life better, especially since it seems sensors are getting packed tighter and tighter these days   Any info, links and photo samples would be appreciated!

I have tested this before but did not keep the photos. Will do so again. Give me some time.

This is just hearsay, but I recall reading somewhere that the difference was on the back-end. The 7D is dual processor and the T2i is single processor, so the difference is that there are half the data channels (i.e. the sensor outputs data more slowly). Technically that would be a "different" sensor, just not so much regarding IQ.

Yes, that is nearly correct. The 7D sensor has two channel outputs for faster frame rate while the T2i only has one.

As you can see the 7D actually does pretty well.  I'm not saying that it doesn't do ok (I think I might have ruffled some feathers before , I'm just saying that I would prefer something that is better than that.

I'm not a big fan of 7D, but it's nothing to do with image quality. So, I am not upset by what you say about the 7D. However, the belief that high pixel density automatically translates into poorer IMAGE quality is a myth.

This was the sample I had seen a while ago showing the noise difference between the 7D and the 5D mkII.
http://www.cameratown.com/reviews/canon7d/
... I think that is one of the reasons why the 5DmkII has better image quality.  The "more pixels is better crowd" might argue that the 5DII has more pixels, but come on, it is only 3mp more (which isn't that much) and when you look at the pixel level the 5DII really is doing better.

While the 5D2 may be better because it has a larger sensor (nothing to do with its absolute pixel count), the difference is really not astounding (i.e., definitely not 2 to 3 stops better like what many people think). Let me quote from your web link:

"While the differences aren't HUGE, the 5D Mark II's full-size sensor definitely made a difference at ISO 3200 and beyond. Of course that means both cameras were fairly well matched up through ISO 1600, not an easy feat for an 18MP cropped-sensor camera."

I should also point out that in the above link, the 7D shots are darker (i.e., lower exposure) than the 5D2.

Another problem with a more tightly packed sensor is diffraction, but that is a whole other topic.  I don't know all of the technical end of it, and I don't want to start a big argument, so I'll quit w/ it here.  Just wanted to show that the less density/better pixels crowd has a good point too

That is a myth that can be debunked most easily. If you compare images from the 12 MP 450D against the 18 MP 7D side-by-side, all the way from f/2.8 to f/16 using the same lens,
you'll see they are EQUALLY affected by diffraction beyond f/8. The 7D is not in any way worse. Some other points to note:

(a) diffraction occurs at the lens, and the sensor merely records what has already taken place
(b) diffraction believers forget about the AA filter in front of the sensor, its strength can be lowered with increasing pixel density

Oh, and I just found one more thing that proved me wrong on an earlier thought I had...DxO Mark is an independent lab that tests camera sensors for all kinds of things (sn ratio, dynamic range, tonal range, color sensitivity, etc).

DXOMark is full of garbage. Their numbers have no real world meaning (in fact, they contradict what you actually SEE from DPReview etc) and they are not even self-consistent. I do not wish to go into all the gory details here unless you really want me to.
