Pros: Long focal excursion with excellent sharpness at least up to 200 then still remains very good
Cons: stabilization (?) and weight
Opinion: Edit 07/19 new rating much more positive: it is a much better optics than its predecessor (which was not to be discarded) than this has improved in all respects: autofocus much faster, sharpness and blurred better, but bracket for the no easel, that one remains scarce. My relationship with him was one of love and hate: using it on my D800 with and without active VR, it NEVER provided clear images. Much better to use it without VR, and in that case the images were very plastic and sharp. The yield drops a bit to 400mm but still remains very good. On qualified sites there are 'stories' that judge it on a par with 70-200, and in my experience on the D800 I considered it a huge panzana, for me it was just good, not excellent; certainly lower than the AFS 300 f4; I thought it was not suitable to count the feathers of the bird on duty, but very good for sports use. UPDATE June 2019: After some intense comparative tests and field use with the D850, I have to totally think again: at least up to 200mm, from the comparisons, it emerges incredibly that, absolutely, it is the best long focal optics in my possession (always after the AFS 300 f4), at 80mm and all opening f4.5, has a sharpness superior to the same diaphragm compared to all the other zooms I own: among them: sigma 24-105 f4 and nikon afs 80-200 f2.8. A 200mm always TA ranks second immediately behind the AFS 80-200 in a "It's a very sad day," he says, "but I'm not going to say that I'm not going to be able to do that." In fact, given the problems of THE VR on the D800, after the first days of use with the D800 I had sent it back to assistance without any defects. On the D800, with VR active, all the images showed a nice contrast, a nice bokeh but also a visible ghost image (double image) particularly sharp on details such as branches etc... even shooting at 1/4000. This does not happen using it using it on the D7200, where I use it happily for action photos (even with the 1.4x) and disappears completely using it on the D850 where it shows its quality decidedly PRO already at full opening and on all the focal points. In my experience I can say that this optics has a compatibility problem between the D800 machine body and the lens, (a known defect of the D800, although there is no semi-official list of good and 'bad' VR optics); D800, which however worked well with all the rest of my set up kit and also with the previous 80-400 VR AFD. The optics is undoubtedly very recommendable and although new costs an eye, you can find it used at affordable prices. Its overall quality is really great, (the golden ring around the barrel deservedly certifies it), but my suggestion is undoubtedly to try it on your own machine body (with the VR) before formalizing the purchase. Basically: it is an excellent optics that gives the best on medium distances, but is very critical in focus and micromovement; it is perfect using the focus of the D850 liveview, instead requires a precise fine calibration of the autofocus when used with the reflex. I believe that on a mirrorless it can be an essential optics. I vote 9th for resolution, 8 and a half for stabilization. |
