Did this side by side today, E-P5 and Olympus 45mm and Olympus 40-150mm, both at f/5, 1/40sec ISO800.

100% crops, Which one is which?

the 40-150 is excellent when not in its telephoto maximum range, and at ~mid apertures.

which is great, because its light and dirt cheap.

call me crazy but i did a 75mm/f5.6 vs the 1000$ olympus 75mm lens and it put up a fight there, too

but you buy the 45mm and/or the 75mm because they CAN shoot at apertures wider than 4

I'll take the bait as I own and like both lenses. The image on the left is from the O45.

I never tried the 75mm but I read everywhere how great it is, if you say the 40-150 can match it too than it's wow!

Correct, a little bit better color and contrast :)

Run tbe same test at base ISO. Raising the ISO to 800 will affect the sensor's ability to resolve detail and make it harder to spot any difference between lenses. Having said that, we are well past the point in lens design where it is correct to assume that a prime lens will always be sharper than a zoom lens at the same settings.

Agreed, but it is still a surprise to find an inexpensive zoom get close to an excellent prime lens even if it is only in limited conditions.
