EOS Bodies / Re: Patent: Dual Motor For Autofocus on STM Lenses
« on: September 12, 2014, 07:55:21 PM »
The pattern is for aperture control (closing and opening). Not for auto focusing.

PowerShot / Re: Three New PowerShot Cameras Coming Shortly
« on: September 12, 2014, 01:06:00 PM »
" PowerShot G7 X, which will have a 1″ sensor and be about the size of an S series camera."
I do not expect the lens to be faster than 2.0 at wide end and(4.0 or slower at long end)  and the zoom range hopefully will be 24-75mm(equivalent). Any higher expectation will lead to disappointment.

Lenses / Re: The New Canon EF-S 24mm f/2.8 STM Pancake
« on: September 11, 2014, 07:52:48 PM »
Canon should be given a lot of credit on this lens regardless whether the lens fits our need, desire, expectation and requirement or not. EF-S mount is with flange focal distance of 44mm. Canon comes up with a 24mm lens that is ONLY 22mm thickness with IS. That is quite an optical engineering success. In order to make it small, Canon cannot give us a f 2.0 lens. Some members complain about why the EOS-M can have a 22mm f 2.0 lens. The answer again lies in the flange focal distance. The EOS-M has a flange focal distance of only 17.7mm.
It is a lot easier to design a 22mm f2.0 lens. By the way, this lens does not even has IS. Some member asked for a pancake f 2.0, 24mm EF lens. That is mission impossible.
You missed because the new EF-S 24mm F2.8 STM has NOT Image Stabilizer.
Thanks for the correction. Even without the IS, the 24mm f 2.8 STM is still an optical engineering sucess

Canon General / Re: Canon Celebrates 80th Anniversary of Kwanon
« on: September 02, 2014, 02:41:51 PM »
At the beginning, EVERY BODY in Japan were making knock off German camera. Canon was making knock off Leica while Nikon was making Knock off Zeiss (Conterex). Canon was trying to out do the Leica in the 1961 and comes up with the f 0.95, 50mm lens. While their range finder camera also tried to avoid the "Leica look" in the 50's.

Pricewatch Deals / Re: Deal: EOS M w/22mm f/2 STM $249
« on: September 01, 2014, 12:30:22 PM »
It is a great deal. Think of it as an over sized P&S. You can put it in a small pouch on your belt. You can use ISO 3200 or even 6400 to get the picture that is still presentable. This lens is sharp while it is wide opened. therefore you may not need the IS for most of the situation.  If you need the flash, you can always put the 90EX in your pocket. 22mm is the most versatile focal length for the APS-C . It is  too bad that  I have paid quite a bit more for this set up.

Lenses / Re: lifespan of IS motor?
« on: August 25, 2014, 04:42:29 PM »
Why do people expect their camera and lens to do better than that???

I guess for amateurs it's wishful thinking because the price for a good dslr kit is very high in comparison what you could do with the money for other recreations like travel... so it has to last, doesn't it?

Thus one interesting question is avoided: Wouldn't it be more clever to by Rebel cameras with cheaper 3rd party lenses, and when they break simply upgrade to the better current model? Certainly not an option for professional use, but less worry about gear damage, theft or wear and for most purposes about the same result :-.o

That is an intersting thought. However, the Higher level  DSLR do have more feature than the Rebel. If the Rebel has enough feature to satisfy you, by all means, go for it.  I have a 20D for 5 years and a 40D for 4 years. Both cameras have the shutter releas button failed. Fortunately, I can fix them with alcohol(Thanks for the instructions from You Tube).  If I cannot fix them, they will be goners.  As for the lens, my 17-40 L holds up very well even after 9 years.  For me, I have got more than what I have paid for. But I start to question the focusing accuracy of he 28-135 Canon lens after 6 years.  I do not have any experience with the third party lenses.
Since I want to travel light, I have just switched to the EOS-M system.

EOS-M / Re: EOS-M and Magic Lantern
« on: August 25, 2014, 02:32:28 PM »
I just got around to adding Magic Lantern to my EOS-M this weekend and wish I'd done it sooner.   I hadn't realized that it adds focus peaking and the magnified 10x image embedded on the viewscreen!  I have a couple of adapters for Konica and Leica lenses that I hadn't used much because manual focus was a little difficult on the screen but with the new tools it's easy.

Are you sure that is a 10X?? not a 2X or 3X???

PowerShot / Re: New Large Sensor PowerShot Rumor [CR2]
« on: August 23, 2014, 02:57:18 PM »
It might be an ideal pocketable point and shoot if Canon can keep the size down. The newer model of Sony has grown too big to be pocketable.

EOS Bodies - For Stills / Re: Canon mirrorless: Status?
« on: August 19, 2014, 12:17:40 PM »
Canon has all the ingrediant to make adecent mirrorless: dual pixel sensor ( from 70D or better), EVF (from 1X MK II), ability to make a smaller body ( EOS-M, SL 1), Fast processor( Digit 6) All Canon need to do is to put them together and comes up with the EOS-M3.  Along with the 4 existing EOS-M lenses, that will make s decent ,  versatile system.

How about a mirrorless full frame camera stuck in an AE1 type body?  No autofocus, full manual controls and good
battery life.  Oh, wait - that's a Fuji XT1 in manual mode.

Leica M9 or M-E

EOS Bodies / Re: SL1 as a "travel" body
« on: August 14, 2014, 01:35:13 AM »
"travel body" seems to be misleading. Unless you are travelling with only one lens on the body, then the size and weight of the body is important. But if you are travelling with 3 L lenses (a lot of the member in this forum has done more than that), than the size and weight of the body does not matter any more. It will be a big " system".  That is the exact reason I bought the EOS M with 22mm and the 18-55 zoom. To make  it to be a small travel system.

Most people accept that their car may not be trouble free for less than 5 year. Why do people expect their camera and lens to do better than that???

EOS Bodies - For Stills / Re: DSRL Camera for travel
« on: August 02, 2014, 03:28:30 PM »
If i want i lightweight camera for traveling, i would never take a camera with interchangeable lenses.

Sure, but just because your camera takes interchangeable lenses doesn't mean you have to take a bunch of them with you.  I don't know where the OP lives, but right now in the UK you can buy an EOS M kit with 18-55 zoom lens and flash for £199.  There's nothing else on the market for anywhere near that price that approaches it for IQ, and it makes a great travel outfit IMO.
The 22/2.0 is only another US$120. It is a very good lens. This will make the EOS-M pocketable for a jacket. It will rake care of the low light situation.

Agreed, although it costs a bit more than that over here.  I love the 22/2, low light or not.
Blame it on the high VAT.
