Hm, OK. . .but why we can see lens limitation on the 8mix sensor if the lens is capable for 16 mpix?

Perhaps because the sharpness of lenses and sensors decline
gradually as line pairs get smaller. There is not a sudden cut of
with perfectly sharp images at, say, 59lp/mm and no detail at all
at 61lp/mm.

Whenever lens and sensor/film are reasonable close in resolution,
the combined sharpness will be noticeably less than either is
capable of alone. For example, if a lens and sensor both have 50%
MTF at 60lp/mm, the combination will have 25% MTF at the same
60lp/mm (MTF factors multiply: 50% of 50% = 25%.) So the image is
"one stop" softer than either the lens or sensor is capable of on
its own, if either the lens were used with a "perfect" sensor, or
the sensor with a "perfect" lens.

Moving away from perfection, the natural combination in digital
will probably be going to sensor MTF higher than lens MTF, so that
the combined MTF is close to the limits of the lens alone. I guess
that because it will probably be easier and cheaper to keep
improving sensor resolution.

Not exactly clear enought but I can accept that I'm wrong. I'm biology high school teacher and I'll trust you on your word (I'll talk with my colege from fisics department

P.S. You originally talked about reoslutio limits of the "pro lenses":

Olys pro lenses are capable for 8-10mpixels on 4/3 sensor.

So why are you now using the example of the 14-54/2.8-3.5, which is
a mid-priced, "advanced amateur" 4x zoom? "Pro lenses" to me
suggests ones like the 11-22/2.8-3.5, 7-14/4, 35-100/2, 90-250/2.8,
50/2 macro, 150/2 and 300/2.8.

Olympus using term Pro lens for 11-22; 14-54; 50-200 and 50macro. For 7-14; 35-100, 90-250; 150 and 300 they use term High grade pro or something similar.

Thanks for the R. . .and sorry on bad english
Cheers

Sorry on bad english .)

Don't worry, your English is very dobro, much better than my Croation.

Thx

I would think all current cameras will be obsolete in 5-7 years.
Even automobila companies operate on a 6 year lifecycle. I
wouldn't be surprised if the next generation sensor has already
been built and awaiting the end of the current lifecycle.

Actually a friend of mine (pro photographer with 3 Canon and 4 Nikon bodys and 3 bags of lenses which was werry impressed with my E1 + 14-54 says that he was talking wit someone (don't ask me who claim that in a few years we will see a new type of sensor which actually exist right now. That was last summer or autumn.

Companies have a lot of incentive to age products. If you are
perfectly happy with your camera why would you buy another one.
That is the death of the company.

Right on the spot . . .but. . .my friends redesigned car looks a little better . . . I suddenly hear some strange voices from my engine

Rather than believe me, read the disclaimer at the top of each group of lens tests,
"Results not cross-system comparable"
and follow the link from their to their lens test FAQ
http://photozone.de/8Reviews/lensFAQ.htm and read the item
"Q: Are the figures comparable between cameras or different systems?"

Olympus using term Pro lens for 11-22; 14-54; 50-200 and 50macro.

For 7-14; 35-100, 90-250; 150 and 300 they use term High grade pro or something similar.

Actually, Olympus never uses the hopelessly ambiguous word "pro" in describing their lenses, at least on the lens road-maps I have seen. Olympus uses the term "high grade" for the 11-22; 14-54; 50-200 and 50 macro, and "super high grade" for the 7-14; 35-100, 90-250; 150 and 300, and the delayed 14-35 f/2.
