I love the form factor and am pleased with the results on my x-t1.

How are these lenses holding up on the x-pro2 with the bump in resolution?
 
It has been shown several times that an increase of sensor resolution increases the resulting resolution with all lenses.

And it improves the regular lenses more than the top lenses.

18/55 it's not good enough wide open at 55mm, it's all i can say.

how it look compared to a 56mm 1.2 closed to F4.

yes it's normal that a fixed lens, closed by several stop it's better, but for sure i can't use a lens so soft as my 18/55 is wide open. things are better at F5.6 and not bad at F8.
 
You are comparing a wide open f4 zoom lens to a prime stopped down 3 stops, I think the results are pretty obvious. Can you compare the both lenses wide open or the zoom stopped down 3 stops?
 
Easy.

I went to photozone.de where they measured several lenses both on a Pentax K10 (10mpx) and a K5 (16mpx). It took the 31mm Limited, an excellent lens, but its wide-open resolution doesn't maximize enven the K10 resolution.

Let's look at both MTF charts:

You can see that the difference between the resolution at different apertures is minimized by the higher resolution sensor. It profits better to the rather mediocre performance wide open.

f/4 is the best aperture on the K10, but it is only marginally improved by going to the K5. f/2.8, on the other hand, gets much more improvement, even surpassing f/4 slightly.

I'm afraid you didn't read the article very carefully. The article compares bodies with different sensor resolutions, it does not compare lenses.

The test is repeated with different lenses, though.

to do what? if i need to shoot at F4 i need an F4, and 18/55 is not usable wide open.

i already wrote "yes it's normal that a fixed lens, closed by several stop it's better, but for sure i can't use a lens so soft as my 18/55 is wide open. things are better at F5.6 and not bad at F8."

are you missing that part?

the author ask about the 18/55 and i say at 55mm wide open it's not good enough imho.
 
Sorry but I believe that it's you that missed the point. The OP asked how the two kit lenses held up to 24MP. Someone posts a comparison of 2 lenses one a zoom, one a prime, prime stopped down zoom open. What can this possible tell you about the 2 kit lenses holding up to 24MP? If the person posted 2 pictures taken with the kit zoom, one on the XP1 and the other on the XP2, now that's something to compare.
 
i posted a Crop of the 1855 wide open, and same crop of a 56 1.2 closed at F4, both on an X-Pro2, to show what the sensor can resolve.. he can decide if that's good enough for him or not..

Enjoying the conversation and the links.

My concern is that will my glass allow me to realize an improvement in the resolution that the higher MP sensor provides?

With the18-55 my biggest concern is at 55mm wide open, as this is the weakest point for that lens and a setting I use frequently. My guess based on the lie stop article is that I will see some improvement in the center and little to no improvement on the edge and that I will probably only see improvement at the edge from the best primes and zooms stopped down.
 
The link you posted is for a Canon, I didnt see any Fuji images
 
any lens will benefit a sensor with more Mpixel, for sure as you say and as i show in my post the 18/55mm at 55mm F4 it's really weak and with 24Mpixel the differenc between the zoom and a good lens will be even wider.

55-200 lens is even better on the X-Pro2. Converted RAW in LR with minimal default sharpening:
