What is 4 times better?

As with your previous attempt to pick a fight with me, I am simply not interested for reasons that would be patently obvious to the vast majority of posters here.
What you call "picking a fight", I call giving a context to one's opinions. 'Course, depending on the opinions one holds, and how those opinions compare and contrast with the photos and the measurements, one could see why some might call providing a context "picking a fight".

Either way, you're not interested, which is probably for the best.
 
Call it whatever you like.

I leave it to others here to discern your motives as they see fit, in the context of your history both here and on the OSTF ...

I would like to ask Mark and everyone else, What do you consider to be "4 x better"?
What is better about FF compared to u 4/3 is shallow DOF wide angle shots and continuous tracking AF.
True.
That is about it for all practicle purposes and print sizes.
Well, there is that business about noise in low light and captured detail, but, I suppose, both of these depend on what the "practical purposes and print sizes" are.
Micro four thirds is better at portrature and telephoto because it has enough DOF to allow you to shoot wide open using a lower ISO than FF.
What is the advantage of f/1.4 1/100 ISO 100 on mFT over f/2.8 1/100 ISO 400 on FF? How about f/1.4 1/400 ISO 100 on mFT compared to f/2.8 1/100 ISO 100 on FF?

The vision behind the person behind the camera, equipment means nothing.
 
A linear resolution increase of 4x alone would require about 216MP. If it were even possible, DR would be destroyed.

But that would not be a fair comparison, the canon is a much faster lens and of higher quality. it has non-extending barrel and FTM.

a closer comparison is to 70-300 IS USM, 649 USD.
Why would you go FF to capture the same images (or near enough) as m4/3s?
Because it is much much cheaper to do so.
If you're going FF, wouldn't the point be to get substantially better IQ?
Yes and no. For critical use, one would go after better lens, for example I do not use 24-85's 85 end for portrait, I buy a 85 F1.8. But for less critical use, where i just want a lens that will give me high standard of IQ, no need to for super high standard, I settle for a cheaper lens - for example, for 24mm and 35mm, I am quite happy relying on the 24-85.

That is a misconception. FF gives you the option to shoot at wider and narrower DOF, that in itself is an advantage. but when you shoot at wider DOF (stopping dow), you do not necessarily have to raise ISO. in the end that you do raise ISO, IQ is still on par with m43. For example D600's ISO400 is abut as good as g5's iso100.

As I have told you in point number 4 that those three top quality m43 lenses cannot giev you more than 10 mp, about half of their money, you can buy Canon 17-40, 50 F1.8, 85 F1.8, they will produce more than 10mp of resolution on any current FF body.
Again, we have to consider the system cost, not the cost of just one component, like the lenses.
While for most people, a system means one body plus a number of lenses. so if every lens cost more to obtain the same IQ, overall system cost is likely to be higher too.
7, 8, More dynamic range and better colour depth. The jury is still out as to why FF do better in these two areas. But measured data indicate that bigger sensor is indeed better. OMD uses the same sony technology as D800 but has less colur depth and drynamic range. os if these two things are on your priority list, you go FF.
All these things depend on noise, which, in turn, depends on the total amount of light falling on the sensor and the efficiency of the sensor. In many instances, we find the smaller sensor outperforming the larger sensor in these measures (e.g. D7000 vs 5D2).
But if you look at D7000 and vs D800 and D600, sensor size is 2.25 times smaller but DR is less than half a stop less. when compared to Sony RX1 and A99, DR is pretty much the same.
That said, DR, in my opinion, is one of the most misunderstood measures of IQ. For example, the Canon G12 (compact) and Canon 5D2 (FF) have the same DR, but we wouldn't say they have the same IQ, right?
As I said, DR is only one of the several metrics that constitute DR.

I don't know what "most people" have, but, for sure, the more lenses you own, then more important the size, weight, and price of the lenses become in relation to the camera, for the system as a whole.

That's what I'm saying -- DR depends strongly on sensor efficiency. However, more than that, two systems with the same DR doesn't mean the same IQ. Instead, the same DR means that detail can be resolved in the same number of levels, but the quality of that detail will depend on other factors.

That said, DR, in my opinion, is one of the most misunderstood measures of IQ. For example, the Canon G12 (compact) and Canon 5D2 (FF) have the same DR, but we wouldn't say they have the same IQ, right?

Panasonic lens is also of very high quality, weathersealed, non extending, etc. I suggest you do your homework before doing comparisons.

I've put together FF kits occasionally to see what would be involved in to move from my m4/3s kit to a FF kit that would work for me. It's never come out cheaper. Usually the weight triples and the cost doubles. Maybe it's much cheaper for you, but that certainly doesn't apply to everyone.

Why most people buy the 135 format is, the lemming behaviour. And the misconception that Canon and Nikon is the best. Especially americans live by this "bigger is better" concept. And ultimately it gives you obese ;-)
Most people who buy FF from Canikon would have owned and shot a SLR class camera for some time. They made a concious decision to move onto FF because there is something they want that their existing camera does not give them. of all markets segments, this is the least "lemmings" type segments.

Canikon is indeed the best when it comes to 135 SLR system. They make the best telephoto lenses for action shooting, they make the best AF system for tracking moving, they make the best flash system, they also make the best FF bodies. in these four areas alone competition do not come even close.

135 is the best balance between best IQ and cost. With anything bigger the cost goes up exponentially. M43 is 1/4 the sensor, but it is not 1/4 the size and its price is almost the same as 135 system.
Ulti, I am around tourists in this tropical paradise in which I live -- you can pretty much pick out the serious photographers, just the handful of them, some with FF, some with smaller formats, some with super zooms, me with m43! :)

BUT most of the camera toters have FF. They just hang around their necks. When they get to the designated look out or event, they take one picture, then the mighty FF hangs around their necks again.

They are photographic lemmings, they have been sucked into the myth that "real" photographers use FF to get top quality so if they have FF and the right brand, they will get the best pictures too. They wouldn’t know a really good pic if it bit them on the bum!

BUT they have their FF SLR -- mostly Canikon.

Good for them. But don’t kid yourself that FF Canikon owners are all -- or even mostly -- serious photographers.Most are lemmings. If they have the money, they will buy the giant tractor, even if they can’t drive and don’t have any stumps to pull out.

You are likely to find far fewer lemmings among m43 and other CSC users. Why? They have broken ranks with the lemmings and made different choices -- they have chosen equipment that fits their needs as photographers and (dare I say it?) people.

There are a view exceptions, of course, but in general -- Viva la revolucione!

Cheers, geoff

It is not a fair comparison as the Canon is a lot larger and heavier.

The Panasonic has a non-extending barrel and is likely of similar quality.

That lens is in a completely lower category of quality and sealing. It is also considerably larger as well.

The bottom line is the lenses are almost never equivalent in the real world.

Generally, when I need FF it is because my m4/3's gear won't work well in that situation. There just is no m4/3's camera that can do what a D4 can.

When I use my m4/3's gear it is because it is a more sensible choice than my FF equipment. No available lens would suddenly change that in favor of FF.

For video, I prefer my m4/3's.

  • portability and being inconspicuous, then it could be 400% worse
Neither my E3 nor my 5D2 are particularly inconspicuous. They are in fact much the same size. The E-4x0 series were cute little cameras, though. Oly was on the right track there, I think.
  • value for money, then it could be 100% worse
Yet it was a lot cheaper to add a stabilized 300/4 to my 5D2 than it would have been to add a 150/2 to my E3. And I mean including what I paid for the bodies. But you meant the other way around, I know. I wish you were right, but you unfortunately aren't in the general case. The good 4/3 lenses are typically neither particularly small nor particularly cheap (to the extend you can even get them anymore :-()

sealing maybe, but how many people have a sealed m43 body to begin with?

End IQ is by far the most important, that is where this cheapo would beat the panasonic.

Please remember we are not comparing general pros and cons.
 
In my book, 90% of image quality is composition (or catching a moment) and has nothing to do with sensor size, but that's just me.

dude are you high? that link you posted is for 12-35. Do your home work.

Because it is not cheap. But it is cheaper than M43 for the same IQ.
the cost doubles.
Not it doesnt. body cost triple or quadruple, yes, but by the time you buy the 3rd or 4th lens the cost could well be even.
Maybe it's much cheaper for you, but that certainly doesn't apply to everyone.
We all pay the same price (more or less) for the same product, the only difference is what we choose to buy. if you buy exactly what I buy, you are in for some saving too.

Then why bother with any system camera, stick to this should do it

BUT they have their FF SLR -- mostly Canikon.
Let me begin by asking this simple question - How do you know they are FF? not just APS-C? do you check the model number on every one of them?
Seriously though, I have done my traveling and my obvservation simply does not coincide with yours. Yes there are the occasional 5D2 + 24-105 jpeg shooters who you just know isnt a "real photographer" per se. But far more than those are the 550D + 18-135 and D90 + 18-105 shooters.
The sales figure also simply does not agree with your observation. m43 and low end aps-c SLr outsell FF by a large margin.
But even if your observation is right - that there are a good number of FF lemmings around tourist attractions, it still does not disapprove what I said. Because there may well be much more FF owners who you do not see in these places, or they may not be using FF.
Good for them. But don’t kid yourself that FF Canikon owners are all -- or even mostly -- serious photographers.Most are lemmings. If they have the money, they will buy the giant tractor, even if they can’t drive and don’t have any stumps to pull out.
I am certainly not advocating FF is the best system for every use and every one. I completely understand that many people prefer smaller systems and agree with them that that is what they should use. But the point here is majority FF owners are experienced shooters, and the proportion of lemmings among them is far less than any other group, sales figure proves this.
You are likely to find far fewer lemmings among m43 and other CSC users. Why? They have broken ranks with the lemmings and made different choices -- they have chosen equipment that fits their needs as photographers and (dare I say it?) people.
But today, mirrorless is pretty much the normal, many people buy them because store sales encourage them to buy mirrorless over likes of Canon G12. they are as lemmings as they get.
