The pictures look very clear and sharp. Is that a lens from the Art Series? Will go have a look, a friend just bought the 50mm for his Nikon from the Art series. Seen several images, they were really beautiful.

These both look very interesting. If you don’t mind the slow maximum aperture at the tele end this pair would make a great travel zoom pair for any Z user and on the Z7 you still finish up with around 20mp in crop mode and both the Z6/7 show a full viewfinder image with DX lenses as does the Z50 of course. Looking forward to the 28 and 40 compact primes too!

If you still have the numbers at hand, would it be possible to change the MTF plots (is that MTF50?) from an “excellent/good/fair/poor” scale to actual LW/PH numbers (or make them available via other means)?

Thanks.

Each term doesn't refer to an absolute value, but to a band of values which is pitched against the theoretical expected maximum for a particular sensor resolution. Ideally all lenses would be checked against a standardised sensor and then results would be totally comparable, but unfortunately this isn't possible. Hope that helps!

How can sharpness be "outstanding" when the Nikon Z 85mm f1.8 reaches much better values on a similar sensor?

Interesting point thanks that the focus ring can also be configured to be aperture or EV adjustments whe in AF mode.

Yes, but which sensor? Every camera will have a slightly different result, even when we strip out all the in-camera adjustments that are accessible to us. Apart from experimental error, which we always try to minimise, there are variations in sensor from camera to camera so there is no uniform measurement. That doesn't mean to say the figures don't have value, but they need to be analysed carefully and there's more to it that just a percentage. We can still tell that this is a lovely lens that delivers the goods.
