Originally posted by Fogel70 Can you explain why the two highest resolution camera in the images below show more detail at ISO6400 and ISO12800, than the lower resolution cameras?
there are many options why that could be...
1st ... maybe this also has to do something with the fact that promotional fees were paid.
(believe it or not, we live in this world. that is just how things work today...
good morning. otherwise one could not explain why a destined sigma lens should have the double effective optical resolution when there is a nikon mount on it, than PK mount though it is the same glass-pfff... FYI:-ffd diff. is marginal) - if things have to get sold, they get sold... think.
2nd ... despite that, i have no idea to where such a comparison should lead, when you leave out the fact, that there are differences in magnification. and optics --->
3rd ... detail is also dependent to a lens that "resolves" very good optical/physical.
if you dont believe it mount an old 35mm varexon lens(the odd one wih the silver aperture ring--M42) on your K-5 or whatever and afterwards compare it to something like the DA 35mm 2.4 which should be very sharp...) both pictures will look very crisp and clear but if you zoom in you will see the missing details on the varexon lens.
4th ... this can not be a 100% crop on both sides, if it would, you would see what i mean.(it comes to ones mind that you just dont want to)-
A N D: IF I HAVE TO SCALE DOWN COSTY SUPER RESOLUTION SENSOR PICTURES SO THEY CAN COMPETE WITH THE LOWER RES.
---> then I CONSIDER IT POINTLESS HAVING A HIGHER RESOLUTION SENSOR.
really! where is the point in having a higher resolution when i have to scale down to gain the impression of detail and sharp borders?
answer: there is none...
and when not at high ISO -- the lower resolution beats up the higher resolution when it comes to clarity to see that, i dont need forum users to post "their" pictures...
where neither they are both 100%crop nor the magnification got balanced out between the comparison pictures... ??
as i mentioned before, if i want to see something alike I just go to:

and have a look for myself..
thank you.
Conclusion: Try it out in real life. You will see. (if you want to)
