The IQ depends how the lens is made ,,, not whether it is fixed or not.
Of course. That's why I said flexibility and IQ.
With interchangeable lenses you usually have several superior lenses to choose from.
I consider that an advantage.
You mention Fuji X100. That may be why you do not yet share my enthusiasm for EVF. Take a look at a Sony NEX 7
If anything should be pigeon holed into a low IQ camera category it is the fixed lens. 
The above quote is you exact word.

Canon need to get FAST AF. As far as I know,even Casio is having faster focusing speed than Canon, LX5 is about twicw as fast compare to even S100. Fuji X10 is pretty fast. Nikon 1 is a speed demon, compare to S100.

A "super G series" ,,, the image quality they want and the single lens they want ,,,
The reason why mirrorless EVF technology will be replacing the SLR in essentially all camera categories is because that technology offers superior performance, size and price. A few action sports photographers will hang on to their mirror boxes until sensor based follow focus outperforms DSLR phase detect. To try to pigeon hole mirrorless into some little camera sub-category is not going to stop its advancement through the camera ranks.
Of course all cameras competing for flexibility and IQ should have interchangeable lenses.
If anything should be pigeon holed into a low IQ camera category it is the fixed lens.
Unfortunately, as it is now, EVF is still pretty slow in response to the change of scenery and being expensive. There is only one camea that  is with the built in EVF (Fuji X100). The rest are add on EVF externally. That will make the camera bigger. Also the focusing speed of the "mirrorless" are slow, compare to the DSLR.  In other word we may still need to live with the mirror for a few more years.
As for fixed mirror equals to low IQ. I am totally disagree on it. If you look back into the history of camera, there are many camera that are with fixed lens with IQ to be better than interchangeablelens camera of the  same time. Just to name a few: Rollieflex, Rolliecord, Retina etc. The IQ depends how the lens is made (and hence pricing), not whether it is fixed or not.

No, not really as I, like many, wouldn't consider it if it gets the same slow lens from the S100 and it's so-so performance.


NO, our whole world, even the universe is governed by the law of physics. However, we can compromise. What if Canon upsize the S100 to be a 4/3 senor with FAST AF, then most people will be happy.

That is exacly why I use the term "compromise". Canon can alway make the lens faster and better with a lens bulging out of the body like the LX5 Or the G series or worst. Then it may not be pocketable anymore.  If we want everything plus the kitchen sink, then the new "mirroless may be as big as the Rebel.  Just look at the NEX 7. It has a thin boy. But is it pocketable with the zoom lens??

In summary, a "Super G" would be great if it had an APS-C sensor with a 24-105mm (equivalent) f/2-2.8 zoom and was no bigger than the current G12, but the laws of physics are probably against this; so interchangeable lenses are the next best thing.   

Those pesky laws of physics!  Can someone do something about that already!

Canon should find ways to get FAST AF (like Nikon V1 ) build an APS-C sensor compact mirrorless with just 2 or 3 small basic lenses and a EF/EF-S adapter. This will get Canon on the map of mirrorless.

They could but its a very crowded market where as like I said I see larger sensor fixed lens mirrorless as a fertile and as yet largely untapped market.

Personally I'm supprized it took so long for any of the big guns to move beyond the typical 1/1.7″ sensor thats been in high end compacts/bridges for years considering how intense conmpetision has been. Not only does it potentially offer what I believe the majority of users are after in a smaller/cheaper package but ties the manifacturer down far less than an interchangeble lens system does.
Canon should "upsize" the S100 give it a 4/3 sensor and throw in FAST AF at the same time. Something like that will satisfy most of the people: large sensor, fast lens, reasonable zoom range, pocketable. Hopefully, the price will be reasonable too.

457
One observation I'd make for the fixed/interchangble lens arguement for mirrorless is the relative body and lens sales of these system. The various m43 systems, The NEX's etc bodies are selling pretty well, not aswell as DSLR's but there  in the same ballpark but the same isnt true for lenses at all where Canon, Nikon and to a lesser degree Sony's conventional SLR lenses still dominate.

To me that says that the real drive in the growth of the mirrorless market isnt so much based on users who want speicalists lenses but rather those who want superior IQ to that offer on compacts.

40D (20D replacement), 17-40mm, 17-55 IS kit lens...  17-40 is my main lens. 17-55 is for low light in museum.

I would not recommend carrying both the 17-55mm f/2.8 IS and the 17-40mm f/4L. I don't even understand why?  On a crop body, the 17-55mm is better in every way - sharper, faster, longer tele end, has IS.  The sole advantage of the 17-40mm is weather sealing, but that only matters with a sealed body, which the 40D isn't.

But...maybe you meant the 18-55mm f/3.5-5.6 IS kit lens?
Neuro, You are abolutely right. My typo. What I really mean is the Cheap and Very Light 18-55,f 3.5 t0 5.6 kit lens. Since my 17-40 does not have IS so the kit lens become very useful inside the museum. I did not buy the 17-40 for weather proof. I bought it for the focal length that I would use the most. It was bought with the 20D before the 17-55mm f 2.8 exists. Thanks for pointing out my mistake. For someone starting out fresh. definitely the 17-55mm f 2.8 is a better choice than the 17-40 f4.

I have been travelling to every continent with the following setup:
40D (20D replacement), 17-40mm, 28-135 IS (35-135 replacement), 17-55  IS kit lens, 8X25 binocular, SD870 IS,  lens hood, filters etc. All fit in a Nove 3 (AW) bag. 17-40 is my main lens. 17-55 is for low light in museum. 28-135 is for just in case I need a long lens. The binocular is an indespensable tool for shows, interior of old churches or temple, distant subjects,  etc.

AS for stiching, please hold the camera in portrait mode and take mutiple shorts to get the wide scenery that you want. I know, you are taking narrower shorts in the horizontal direction. However, that will give you more in the vertical direction. If there is a slight alignment error, you will not end up with a very skinny panaromic picture. personally, I tend to stay away from "super zoom", too much compromise.

461
I think one of the reason why Canon is holding back on mirrorless is the focusing speed. As it is now, Canon has slow AF speed in their  P&S. Even the newest S100 is having AF speed at over 0.5 sec. Would I pay $1000 for a mirrorless with 1/3 times the focusing speed of my DSLR???

« on: December 19, 2011, 06:02:52 PM »
The 35 f/1.8 may not be EF-S. If Canon wants to make a "Standard" APS-C prime, it will be 30 f/1.8 to give us the angle of 48mm on a FF.

Some amazing answers here, thanks you all very much, I have thought about the kind of situations I might be in for photography on the trip, it is all organised and so I don't think I will need the 70-200mm, so the 10-22mm and the 15-85mm sound like two very good lenses that I will use, a limit to just 2 lenses (probably won't use the kit lens) will prevent too much weight, and also allow me to set up faster and take the photo I want on any time I have during the day.  I will try extremely hard and buy a tripod too.  A couple of you have also recommended Circular Polarizer filters, so will have a look at those. Regarding the 15-85mm and 24-105mm, what are the benefits of each one, as different people like the 24-105mm, and some prefer the 15-85mm.

Thanks, I really appreciate all of the help you have all given me, James
I would pick 15-85 instead of 24-105. 24mm will be too narrow for city scape and landscape.  15mm will give you a much wider view. However, the 24-105 is faster at the long end.  If you have room in your bag,  bring the 18-55 kit lens for bad weather and/or dusty envioment. It is better off the put a $100 lens in harms way than put a $800 Plus lens in harms way. Another OP suggest a small point and shoot. It is an excellent idea. In extremely bad weather, you can risk a cheap point and  shoot but not a $1800 plus set up.

neuroanatomist: I am 6'2" right now, but I am probably going to get taller, as I'm only 14 at the moment, the tripod I found is a Manfrotto 055CXPRO3 it looks really good and extends to a good height, also, with a ball head it sounds almost perfect, but if I don't manage to get it for Iceland, I could try a gorillapod.

Thanks for all of the other information, I will see if I can find three or four lenses, definately the EF-S 10-22mm f/3.5-4.5 USM and the EF 70-200mm f/4L USM (Non IS), and then I can decide on one others, I still can't decide, I am thinking not so much towards the 50mm f/1.4, and maybe go for the 17-55mm or 15-85mm because of the range in focal lengths, but is it worth it? as 50mm is quite well fitting between the 70-200 and 10-22mm, and a lot cheaper.  I would have the kit lens, just in case, but I could still sell it, and maybe consider one of the other standard zoom lenses.

Would I need a good 'general' lens?  Not sure whether or not I could afford it (15-85mm?)  I could always hire it, not very expensive at all

Thanks, James
What lenses you pick will also depends on the nature of the trip to Iceland. If you are on your own, you  will have a lot of free time to set up the gear and take picture. If you are on an organized tour, you may not have the luxury. It also depends on you shooting habit and experience. There is no doubt that both 17-55 f2.8 and the 15 to 85 are very good optically and are perfect walk around lenses. You have a choice between  speed and reach. As for flash, there is no such thing a  too powerful. The more popwer the better, especially if you are using defuser etc. Camera bag is the most personal item. You need to tray it out with your equipment.  Amnother word of caution. most European air line are having 8 Kg limit for carry on. Please be aware of that .

EOS Bodies / Re: The rift between the vocal "ISOers" and the "MPers"...
« on: December 12, 2011, 01:58:26 AM »
I am look at it from a practical point of view.

It  was well documented in this site that 7D at low ISO is more noisy that the 12MP XSi ( both straight out of the camera in jpeg format). After post processing the Noise is much lower for the 7D.  Sure, high MP will give us more information with more noise and slow down both  the camera anfd the computer at the same time. How many of us will constantly made 40" X 60" prints?? How many of us are willing to sit in front of the computer and do post processing for every picture that has been taken?? At that same time, most of us will like a DSLR body with the feature of a 7D or more if we can at the same time most of us are not willing (or able ) to pay for a 18 MP FF 1Dx.

So, for me the happy medium may be a 10-12 Mp APS-C or 21-24 MP FF, both with the lastest sensor technology.  Either one will give me low noise at low ISO in jpeg ,straight out from the camera, without any post processing.  The high ISO performance is just a bonus. If the technology has been advanced to a point that high MP will give us low noise without degrading the detail, then I will be glad to take both high mp and low noise at the same time. Even then I will need a 10GHz CPU in my computer to keep up.
