I paid 100€ for it; "if she doesn't like -I thought- I sell it for the same price". She didn't like, so I started playing around with it on my D750. Differently from Nikkor DX lenses, this one does not tell the camera to switch to DX format, so half of the times, I ended up with full frame pictures with the built-in hood taking most part of the frame. I soon realised that those pictures, taken at 10mm, were way more interesting than any other taken with the DX crop. I exported them in Keynote, applied a circular mask et voilà: good old fashioned circular fisheye-like pictures. Really impressive. Really fun! Of course you have to accept some compromises. First and foremost: you can only shoot at f/8. At any other aperture the performances are heavily compromised: more open, and the corners are super-soft, more closed, and the diffraction decrease the sharpness dramatically, this time across the whole frame. So, generally speaking, in order to get sharper pictures, better opening rather than closing (wired!). In summary, I highly recommend this lens as a (very) usable alternative to more expansive ones. To have an idea of what you can do with it, I just posted a dedicated gallery: Tokina 10-17mm f/3.5-4.5 on the field sent on April 15, 2020 |
 | Nikon 50mm f/1.2 AI-s Pros: TA yield, mechanics, character, Bokeh Cons: TA focus, coma, backlit Opinion: If I were to venture the classic cliché comparison, I'd say it's a thoroughbred stallion. Difficult to "mount", nervous and unpredictable (especially because on the D750 -but I read that it is a general problem- what you see in the crosshairs at f/1.2 is NOT what you will see in the photo). But if with practice and perseverance you can tame it, then a world opens up. I use it almost exclusively at 1.2 (let's make one thing clear: if one invests 350-450 euros for a fifty, it does it for that quid in more than a 1.8 or a 1.4 do not give you), and after the various 85mm (at least three), the 105 f/2.5 and the 135 f/2 , I finally found my portrait lens. Eye (!) to the eye: only one can be in focus, and you still have to choose between the iris and the eyelashes: at f/1.2 you can't have both in focus. For the rest, closing becomes very engraved (Although it is not true - as some say - that is the fifty sharper than the Nikon from 2.8 and up, indeed), but the chromatic aberrations due to the extreme slathery of the lenses are felt (and see, above all). I wouldn't use it for astrophotography... sent on September 14, 2019 |
 | Nikon 300mm f/4 AF-IF ED Pros: robustness, optical quality, integrated lampshade, bokeh Cons: non-removable tripod bracket, weight/clutter Opinion: In my opinion it is one of those optics that can not be missing in the backpack of the evolved amateur. I had 3: when I got tired of the weight and clutter I sold it, then wept crocodile tears and bought it back immediately. Compared to its descendants it pays in weight, clutter and infinity AF, but offers goodies not a little, such as the 39mm filter slot, the telescopic lampshade and the most practical fire limiter that Nikon has ever been able to give birth to, thanks to the blocking screw that offers a unexpectedly comfortable. From an optical point of view there is little to say. The homogeneity of the yield on the entire frame is legendary, and only at f/4 is a soft hair. The colors are neutral and do not fear the backlight (probably thanks to the limited number of air/glass interfaces and the inner lining of the barrel); I must say that on this point some judgments are conflicting, but as I have written, I have owned 3, and I do not remember ever having problems with contrast drop or flares. The bokeh is also very neutral, with extremely homogeneous light point yields. Last not least, the price of the used: the last one I paid for 260 euros (2019). sent on September 14, 2019 |
