I know sigma 8-16, they havent even launched it for their own Sigma mount.
it is available from stock in Canon mount from many dealers in my area.
I mentioned about Sigma Mount, its different than Canon. Its in release pipeline, but not released yet. E mount is not even in any official disclosed plan and you are counting it in?
Even their 10-20 is not upto par to Tokina/ Tamron lenses in many grounds. You are again counting on Sigma?
Check the user reports e.g. on the Canon lens forum, the 8-16 Sigma is an excellent lens for almost half the price of the Oly/Pana 7-14 lenses, that do not even offer the same wide field of view.
Canon lens forum is to get people opinion, let me know any official review, if you know any where you can prove its better than Pany 7-14? or even close. Just having wider coverage is not enough.
Sigma has many (EX) lenses that easily outcompete most of the stuff available on (m)43. Yes, they also have some cheap low quality stuff, but you are severely underestimating them.
I know sigma mate, don't give blind verdicts, show me where you think it outcompete? It only complements 43 or M43 lenses. Show me any lens better than Olympus 7-14 on any from any manuf, you know, that develop it for any Sony mount.
Have they announced any for sony E? I think you sound very clear about Sony E Mount, that its so different. Don't consider all normal SLR lenses gonna get released for E system. Sony Alpha is ok .. but E .. eeeeee??
From the optical side E-system is identical to APS-C, because it is the same sensor size. It does ALLOW for special (more compact) designs but basically every existing lens can be mounted just by changing the mechanics. I don't know if that is going to offer a good solution because of AF, but that is the same problem that m43 users have now with their lens choices. Very few lenses over fast AF.
There is no optical side of E-system? you meant Electronics of the APSC Sensor? Optics is related to lenses ... glassss!
That's the whole point about m43 lenses you are missing. the mount is small, so you get the advantage of smaller lenses.
no, I did not miss the point at all. I agree for a superzoom m43 can offer smaller lenses compared to E-system. But if you want a small, slow lens with maximum zoom range, most people would be better off with a superzoom compact. The small flange-back distance with E-system could be more important for lens size than the small chip of m43 (note: I say 'could' , it depends on design compromises).
Why slow again??? slow lens means lower f number, where you think 14-140 is slow as compare to Nikon 18-200 VR?
Canon 18-200 IS?
Sony E system future release of 18-200 f3.5 - 6.3??
You think 6.3 is faster than 5.8
I couldn't see what you are trying to prove here?
compact camera f number
so an f2.0 lens has different speed on different cameras?
Where you getting all this information mate?
Please tell me the equation you driving f2 and f2.8 on two systems above?
I don't say the f-number has different speed, of course f/2.8 is always f/2.8. But for a given f-number, the effective DOF and high ISO noise depends on sensor size. Do the math, f/2 on m4/3 is similar (regarding DOF and sensor noise) to about f/2.8 on APS-C and about f/4.5 on FF.
I know my math, but you use your memory, you mentioned f number 2.8f on APSc gives same exposure on m43 2.0f? How come????
Now noise is a new front you opened ... Noise depends on a number of parameters not just the size. I dont use ISO beyond 400 or any other camera. Show me where you think its noise level at even 800 ISO on GH1 is a major issue as compare to any APSc. I never actually said m43 noise is my favourite, on the other hand in my first message I wrote if high ISO is your priority (mine is lower ISO) go for full-frame dont even stuck with APSC.
DOF I aggree bigger sensors have more, but m43 DOF is not as bad as you think as of compact, maybe. It is goood enough for any major portrait work. Well actually many photographers preffer 4/3 sensors DOF, as at lower F numbers it gives more exposure but without blurring too much of the subject. Landscape photographers including me, love 4/3 DOF because at wider appertures 11 or 12 we get hyper focal distance raither than 16 or 18 on APSc and full frame where diffraction kicks in.
On Video recording specially GH1 M43 sensor has so many advantages:

so if we exclude the lenses like 70-200 f2.8 and beyond for E mount. Then I don't see any point buying it, same goes true for M43. I would buy a separate DSLR for it. By the way, sony pancake is not walk arround, standard or day to day lens, its too wide for that IMHO.
that is your opinion, but many people have a different view. Watch the market, there is a lot of interest in compact designs with high image quality and wide to normal zoom range. Most of these people are not interested in BIG (long zoom, tele) lenses, because they already have a DSLR for that.
That's what am saying, if fast big telezoom is not the option on this type of cameras, than why not already well tested 4/3. As ultra-wide to normal zoom lens is pretty well covered by Pany and Oly. E-mount got no ultra-wide even announced yet. Or are you depending here on 24mm eq pancake again??
