Marco, I have not up-to-date each of the Imatest figures on more mature reviews. The numbers around the 300mm f/4E PF VR assessment tend to be more current and proper. I'll update the 300mm file/4 AF-S evaluation with the proper quantities when I do the complete TC tests using the TC-14E II / III and TC-17E II.
The largest difficulty with lenses such as Nikon 200-500mm f/5.6E VR is sample variation. As talked about in this evaluate, two out of five examined copies from the two hundred-500mm VR exhibited disappointing sharpness with the long conclusion on the zoom array. We observed fairly big discrepancies all through lab tests also, with a single lens carrying out beneath common at 500mm, Specifically that has a teleconverter. If we confined screening to a single lens copy, our final results could have been perhaps misleading, particularly if we ended up with the inferior lens duplicate. Unfortunately, supplied the zoom vary as well as the low price tag place, sample variation is always gonna be a difficulty, regardless of the company.
3 kg of excess weight in essence pushes into a single area. A far better solution to style a tripod collar in my opinion, might be to stabilize the lens at two points, just like what many Kirk and RRS replacement lens collars do. I'd Individually swap the stock lens collar using this type of one particular from Kirk and when I made use of a standard ballhead or perhaps a gimbal head that mounts the lens inside a landscape orientation, I'd personally also get this more accent to support the load from the lens in two parts. As being a term of caution, never Enable lenses this weighty just dangle off the digicam mount, as implementing an excessive amount tension may tilt or damage the digital camera mount and perhaps even break it. You will find a motive why such lenses are shipped that has a tripod collar!

Our team is on the lookout ahead to re-screening autofocus general performance when coupled With all the D5 or perhaps the D500.
In my area and lab assessments, I found the vibration reduction with the Nikon 200-500mm VR for being extremely effective. The lens furnished sharp results regardless if capturing three-four stops under the reciprocal rule advice, which is what just one would normally get with the most recent technology Vibration Reduction technique on Nikkor lenses. As usual, permitting the lens stabilize and employing a stable hand-holding method had been crucial in lessening the quantity of blurry pictures due to digital camera shake.
The lens peaks in sharpness at 300mm, delivering excellent Centre effectiveness and rather reliable mid-body and corner effectiveness. As we zoom in past 300mm, the sharpness begins to drop a bit:
