EOS Bodies / Re: When will we have a full frame body below $1,000?
« on: November 28, 2012, 03:00:17 PM »
It is price vs feature again. Canon should be able to make a $1000 FF DSLR even now(plastic body, with minimum feature,  Porro-Prism, NO AFMA, center point AF only, 2 FPS etc ). But, how many people would buy it?? On the other hand All Canon newer FF DSLRs are loaded with features and hence with a higher pricr.

Regarding the actual manufacture of CMOS sensors ... Canon had put out a white paper on this topic a few years back that still has relevancy now.  I found a download location for it here.

http://www.robgalbraith.com/public_files/Canon_Full-Frame_CMOS_White_Paper.pdf

It is a decent read.  Shows how they could only get 20 FF sensors on a 8 inch wafer but could get 200 crop sensors on the same wafer.  Also discusses the various processes involved in creating these sensors and what can go wrong.  Unlike many other camera makers, Canon makes their own sensors in house.


This white paper has been quoted many times in this forum. Unfortunately, this is dated  back to 2006 and there are a few mistakes in the paper. Let us use with the most obvious. Canon claims that they can have 200 APS-C  sensors from the 8" wafer. My estimate is only 75 APS-C on an 8" wafer. You can draw it out by yourself and see the mistake that Canon has made. I think Canon was using these number to justify the high cost of the FF sensor and hence the high cost of the FF DSLR.  6 year in silicon fabrication is almost 2 lifetime.  Most stuff that was  in the white paper  has been changed a few times. Also Canon should have moved to 12" fabrication already.

Lenses / Re: 24-70 or 70-200??
« on: November 20, 2012, 11:52:01 PM »
I currently have been using the 50mm 1.2 with my MKII for portraits and indoor shoots. However, I would like to expand my lens options and needing a general zoom lens so I have read plenty of lovely reviews about the 24-70 and 70-200. Eventually I would love to have both of these however I can only purchase one of them at this time. Any suggestions on which one I should start with that could give me a good general use until I can also purchase the other? I am torn at this point!
It depends what you call "General Use".  If your general use is indoor group shots, cityscape, building, wide scenery etc, get the 24-70. If your general use is candit portrait (people, animal or birds) from distance, get the 70-200.

Lenses / Re: Thinking about a 17-40 f4L USM. Thoughts?

Thanks for leting me know about the price difference. I do not realize that the price of 17-55 has came down to be about $1000. It used to be about $1200. Based on Amazon's price, there is still 43% difference. If I were in the market now, I would get the 17-55mm. For $300 more , It gives me one extra stop and the IS. It sounds like a good deal to me.

EOS Bodies / Re: February & March are Announcement Months for Canon [CR2]

A second EOS-M???  The existing EOS-M has slow AF and hence cause a lots of posters to put it down. Sony, Panasonic, Olympus, Nikon even Casio (P &S), all have FAST AF. What has happened to Canon??
I would buy a EOS-M only if it comes with fast AF.

Based on your 2nd post, looks like you are using a APS-C camera. 17-40mm is a great lens for APS-C. Some poster may say that the 17-55 IS 2.8 is a better lens with about 80% more on the price tag. You will gain 1 stop speed and IS with slight increase in CA.  I have used the 17-40mm for more than 7 years on a APS-C body. It is my main lens.

But what's next - a camera designed for left handers?

Get an Exakta. It is all left handed, including the film winder.  :=)

Lenses / Re: Shooting low light event with 50 1.8II or 15-85

Flamenco is a dance with very fast movement. Therefore you will have more problem with the subject movement than than your hands being shaking. Bring the 50mm 1.8.  I would use center point only to make sure that the subject is in focus. I think (I am not sure, check your manual) in this focusing mode, the metering also becomes sport meter for 60D. Use ISO 1600 or 3200 if the noise is acceptable to you. A noisy picture is better than no picture or bad picture.

PowerShot Cameras / Re: Canon PowerShot G15

Both G13 ang G14 will not never see the day light. "13" is an unlucky number for the westerner. While "14" sounds like "sure death" in Chinese.

Street photography is something different. DSLR here isn't the best choice. Fuji seems to have taken this into consideration.

The best "street shooter" camera is something with a waist level viewfinder such that the camera need not to be raised to the eye level to draw any attention. Therefore  some canon DSLR is best for the job, e.g. 60D and the T4i. Some mirrorless with swinging screen will do too. In the old film days, both the Hasselblad and Rolleiflex will be excellent choice, dispite of the larger size of the camera, due to the 6 X6 cm waistlevel view finder.

BTW, Rocky, the M9 is 100% manual focus ;)
That is that exact reason why I singled out the M9. With Zone focusing, it can beat the AF

Look at the first generation FF camera and the images were garbage compared to well scanned and digitally edited film captures.

Thanks for telling us that the 1DIIIs (first FF by Canon) is garbage.

{1Ds}

Thanks  for the correction. I agree that with 11 MP, It cannot beat the fine  gain film.

I prefer to have my DSLR AF speed over any existing Mirrorless ( except M9) anytime.

my first real SLR that I bought was the 450D, so before the age of digital how did Canon differentiate its model line up feature wise?   I mean back say year 1998 the determiner of IQ was the lens and film and the paper that it was printed on.  My point is, why have so many sensors across a brand's line up, with 1DX sensor, 5D3, 5D2 and then the rebel line up of sensors, if all camera's just over a decade ago had the same ability to capture light correct?  So what you pay for then is build quality, FPS, and metering etc.
It all bolts down to two item: Money and Requirement. Use existing Canon lineup as an example: On the FF, we have the IDx and the 5DIII with different sensor, different resolution, different physical size and different feature. So if you are into FF then you have your choice depends on your requirement and how much you want to spend.  The same goes to APS-C with the 7D, 60D, T4i and Xsi. Then between the FF and APS-C that is another choice.  In order to get the most out of FF execellent lenses are required. So everything is more expensive  with the FF body. On the other hand,  APS-C serves another purpose.  For people that never make 20X30 inch print It is an excellent media. It is cheaper than the FF with less requirement on the lens (using the best part of image circle).  Also for the "bird shooter", a shorter lens can be used.
