I often read that cheap lenses suffer on FX sensors...but.....I just got the D610 and have learned yet another lesson....
The quality of the 610 sensor's IQ @ 3200 make it possible to use F8 with a nice fast shutter speed in cloudy situations getting the most out of such lenses...
It's nice that I can meter with them on the Nikon, and it's nice that the 610's LED confirm focus works well too...also nice that I can view/focus wide open while the aperture is set for a smaller aperture....
I just shot this with the really cheap manual focus Tamron Adaptall-2 70-210mm/F3.8-4....ISO 3200....@ F8.
This is full frame and 2 crops, center and corner...
These are not 100% crops because that isn't how I shoot..
However, these are 3200 pixels wide crops reduced to 1600 wide, crops I may have to resort to, and are posted here as examples of how well the 610 works with such a "low-rent" lens....Of course, the less cropping the better.
...I've had the 610 for only a week and I'm very impressed with how much I can get out of my lenses....most are Nikkor primes, but the Vivitar Series1 zooms I have and this Tamron are surprisingly good...
