When is 24-50mp not 24-50mp? When the lens won't support it
In article , Rich A
wrote: No, not the centre, the edges. If your lens won't support edges, you either put-up with second-rate images, you crop (which reduces overall resolution) or you frame images so as not to include the far edges of the lens, which also reduces total resolution. Specific area resolution is ok, provided the lens is decent in the centre, if you frame an animal in a wildlife shot using only part of the field, that part of the field will have a higher resolution than the same area done with a camera with fewer pixels. However, if the lens is poorer in the centre than other lenses, then none of the images produced may actually have 24-50mp resolution. Tragically, it seems more than a few people buying into high megapixel full-frame cameras (some of which are now relatively inexpensive now) cannot afford the lenses needed to full exploit their resolution. Those poor souls are left to soft-focus portaiture or other gauzy, pseudo-evocative images. So, got any examples of people that buy the 36MP Nikon D810 or 50MP Canon 5DS and put crap lenses on them? If not, what's your point? -- Sandman |

The similar focal length equivalent and price $750 lens on 1/4 frame Zuiko ED 9-18mm f4.0-5.6 rates 9 Perceptual Megapixels, and in terms of "equivalence" is the same as an 18-36mm f8-f11 lens on FX. For a "portrait" lens, then a Nikkor 85mm f1.8 G thoroughly and totally annihilates the Panasonic Leica DG Nocticron 42.5mm F1.2 ASPH, yet the Nikkor is less than 1/2 the price. |

How do you really think Fuji x-trans would stack up? I actually quite like the system, but the concept of the x-trans sensor itself is serious bull**** - an answer to a problem which really doesn't exist. |
