This thread got me going through my negatives and scan a few frames taken with some P&S cameras i had (at 4800dpi). Here is what i noticed.
* On the top of the chain, there is the Fuji DL supermini - the pictures rival easily the best 28 mm lens i had, the Zuiko 28 f/2.8 - beautiful performance but rather expensive and difficult to come across.
* Then there are cameras like the Yashica T4/T5 and the Nikon L35AF, very close call to say which one produces finer details - sometimes it was the Nikon sometimes it was the Yashica - I have a comparison test
here. Problem is that i had to go through a few yashicas as some of them suffered with inconsistent focusing.
* I will put the Konica's A4 or Big Mini, Olympus Epic / Olympus stylus, pentax espio mini and Nikon AF600 in the third scale in terms of how much detail i notice in the pictures -the Stylus epic does a bit better than the rest. All very contrasty lenses, people will be satisfied with them.
And a couple of other random things i noticed - the pictures i got from a Ricoh 500G easily sit between the Yashica T4 and the little Fuji, made me regret selling it. Also, i was underwhelmed by the performance of the Takumar 35 f/2, not much better than the Olympuses (if any at all actually) and no match for the Yashica/Nikon L35AF.
Edit: Also underwhelmed by the Oly XA2 optical performance. A lot of vignetting and detail-wise it wasn't great either. The Stylus/Epic are better...
Just my 2c
