Silly rumor season - Canon to change their lens mount?

[digiguy]

According to someone who knows someone who saw someone, there's a Canon body being demoed that does 22MP.* So far so ordinary. The potentially startling thing is that they're thinking of a new lens mount to accomodate a new lens design.* http://theonlinephotographer.blogspot.com

Even if this is all a bit of silly season fun, would there be any limitations in current lens design when it comes to such dense sensors? I guess there must be a mathematical or optical limit somewhere, but has anyone actually worked it out based on current lenses?

[Mr. Pickles]

I think the "reasoning" is because the current lens mount does not allow for "sharp" images when using a wide lens. Something about the flange design that makes really wide images (less than 20mm in 35mm terms I guess) become "soft" or some such.

In my ka-noodling around I have run into references of such things.

I've seen it in regards to 8 and 10mp rebels.

See this review and read the resolution test section:* http://www.photozone.de/8Reviews/len...5_28/index.htm

Excerpt "* * In fact the center resolution of the lens is among the very best tested to date (incl. fix-focals) and it probably exceeds the limits of the 8 MP sensor of the EOS 350D...."

Read another way .............* This is one of the few lenses we have ever seen that can actually take everything the 8mp sensor of the 350D can throw at it.

Some thoughts for you. Then some opinions.

Thought: *It's not the first time I have heard a rumor that Canon is going to go into the medium format business.
Opinion: * *It's all about the upgrade path. The bar on the high end must be raised.
Opinion: * *It's got to be difficult to resist being able to sell a camera for 30k and the cheapest normal 80mm lens is $1800. (HBlad Rates)
Opinion: * *It's even more difficult if you make your own imaging sensors and you may be 2-3 years ahead of everyone else.
Opinion: * *As far as marketing , If you can get Annie to start shooting with this new system, it's a coup. Game over. You're set.
Opinion: * *There IS a glass ceiling (heh) in DSLR and if we have not already hit it, we WILL in 2-3-4-5 years. If you make a living hawking this stuff, you better have a plan and you have to take care of the high end, just like the car companies spend millions to race their cars - they know that winning races means money on the showroom floor.

Just my 2 cents. Of course I could be on the dark side of the moon....we'll see. Maybe at PMA, maybe later...but I think it makes sense.

I for one am wondering what Canon may be up to.

I like your thoughts about Canon moving into MF. Sounds very seductive, and gives them an opportunity to upsell for those who think 22+MP is not enough (and for some people I guess the amount of mp's will never be enough).

Yes, I have heard that reported in many places, though some WA lenses are better than others so it can be corrected optically within the EF mount I presume.

[Kevin Barrett]

I heard something similar from a reputable Canon dealer who heard it from his Canon rep. They've found that they are limited to where they can go as it relates to current sensor/lens mount design. Translation: Don't expect significantly higher resolution bodies with the current EOS mount.

It wouldn't surprise me if Canon were working on a new mount: EF-S, EF and .

[brian.austin]

Nothing in the rumor mill mentions the 22MP being a medium format.* Why can't it be a different 35mm-like design?* Or are we referring to medium format in terms of resolution only at this point instead of sensor size/dimensions?

Doesn't the EF-S have a flange that penetrates the body more than EF?* I don't have one with me.* If that's the case, how does the 10-22 EF-S manage to do WA so well?

How far is too far with sensor resolution?* Is anyone going to notice the difference between a 16MP image and a 22MP or 39MP image?* I'd rather see better dynamic range and improved color rendition, maybe in a Foveon-type sensor.* What about HD?* When are we going to start seeing HD sensors?* They are hitting video now.* Why not stills?

To me, NO.

To others out there, and ESPECIALLY those at DPR, YES, they can tell the difference. Absolutely. However they probably never have taken a picture worth a poop.

Post any images you want on here, strip the EXIF, and nobody will tell you whether it was an 5mp, 8mp, 10mp, 12mp, or 36mp image. Unless you post it full size. Or print them all "full-size" at the same DPI.

The whole mp business is a marketing and money grabbing tactic that I really think Canon invented. Everybody claims they do everything the best and first and most often, so we can blame them.

I think there is some technical thingie that says that the lenses can't resolve as much as the sensor or the sensor can't keep up with the lens or some other such deals. So everybody needs a new camera mount and new lenses and might as well get ne memory to go with them. Oh, and you need Vista too.

[Rumpole]

I also like the idea of Canon going into MF.

I suppose there's a limit as to how many mega pixels you can squeeze into a sensor of certain size?

I have the 10-22 and yes it does WA very well. EF-S lenses do go into the body further than EF... I'm not an optical expert, but this approach is optimized for the APS-C sized sensor and I believe the thought is that a closer proximity to the sensor allows for the lens construction to be as small as it is.

Don't be surprised if the new flagship is less than the "22MP" that has been bantered about the forums. I'm thinking it will be less, and I think you'll see Canon emphasize 'other' attributes of their sensors in the next gen bodies etc.

I don't need more pixels... but please give me a camera that doesn't cost the price of a car, that will do 16 bits....

I don't get it. Isn't this what the OP posted?

[Paul Shields]

Maybe it has more credence if seen on DPR .

Reason # 1: Click the link the OP put up now and see how far you have to scroll. In another day or two it will be off the front page.
My link takes you to dpreview where the link posted takes you directly to the frame for easy reference.
Reason #2 : If you are interested in the topic , DP's thread has and may yet have additional information as it is still being updated.

Here is the direct link to the article for future reference: http://theonlinephotographer.blogspo...umor-mill.html

Hope this helps.

If it's perpetrated so much on the Internet, it must be true.

The rumour is based in part on Canon’s history of abandoning technologies at any level if it cannot bend to Canon’s ambitions. Whilst the move to a bigger lens mount to facilitate Canon’s AF system and the re-adoption of the bayonet mount alienated a lot of customers, in the long term Canon gained exponentially and beyond her wildest dreams as the new technologies proved worth having.

I think Canon are holding all the aces and cannot lose whatever she does.
