That's weird. I looked at some of the sale prices on that website, and that's more or less what has been ongoing here since December or even earlier, without any interruption. Would Nikon be kinder to Europe, for a change?
There is an
Nikon Action in Europe as well. I don't know from which country you are, I am from Austria. And I had been thinking for a long time about 600PF .. I have 180-600 and it is a brilliant lens! But when I was shooting bee-eaters with that lens I couldn't hold that lens too long ... So, I decided and already paid
3900€ for 600PF. It must come this week. So, my store (Hartlauer) obviously sold some pieces and now I need to wait a bit for my copy ;-) If you are a freelancer than you can also deduct value-added taxes.
The
Action is prolongated until 27.01 (originally was until 13.01).
As for Viltrox - I had a look at 75/1.2 APS-C for my Z50 II but for my test the images have too cool colours and for me it looks like it lacks some resolution, there are too less details in lights and shadows.
The lenses have a lot of characteristics and sharpness is only one of them and often not the most important one. There is also a bokeh, 3D-look, representation of colours to name a few of visual characteristics (plus vignetting, coma, CA's .. etc what can be well corrected in post)
I have Sigma 135/1.8 and Zeiss 135/2. And when I took pictures of wild dogs under the tree at noon with Zeiss in a harsh light in Africa, I could still recover in LRC all details in shadows and highlights! And there was still space to move the LRC sliders! So, I could have recovered even more. The resolution (lines per inch) of Zeiss was just incredible and much better than of my other lenses (I tested it against Nikon Z 70-200 S, Tamron 70-200, Sigma 135/1.8) and I think, it helped to recover the information from the file.
The transition from sharp to unsharp was also very pleasing as was the bokeh.
Some lenses can have min.aperture f2 but can have better or more pleasing transition and bokeh than lenses with f1.8 or f1.4. It depends on geometry and kind of grass (Zeiss uses lead, for example)
Nikon's Plena (I don't have it) probably has more saturated colours than Sigma 135/1.8 because Nikon lenses usually provide more vivid colours than Sigmas and Tamrons.
But Sigmas have very nice circled bokeh and they are sharp. So is 135/1.8 - sharp, nice bokeh, nice skin colours but I couldn't recover any details in lights and shadows.
I am afraid that Viltrox will not provide the colours I'd like to have and in my opinion better to save some money and buy the best, what you like, what you need for your photography, for your goals and what will bring you a lot of joy. Perhaps, my new 600PF will not have such vivid colours like 180-600 (because of PF elements) but I will get
every bird in flight!!
And I will carry it with me everywhere becasue it is light. And shoot and shoot. So, it will bring me a lot of joy and fun. This is why I made this decision.
If I'd decide between Viltrox and Plena than I would prefer Plena... What for sense to pay less and never use it? Or to be not satisfied, not happy?
To take decisions I always go to Flickr. There are groups according to the lenses. So to say almost every lens have its own group and you can have a look at pictures of other photographers taking with a lens you consider to buy. For example, there is also a group for Viltrox 135/1.8 but for E-Mount. I assume, the construction for Z will not differ too much, but there will be a Z-mount. So, you can have a look at pictures taken with that lens and than find a group for Plena and have a look at pictures and so on ...
