Hiking in a wilderness setting, what about using a photographer's back pack?

My thoughts, exactly.Yes, it IS quite soft wide open, especially compared to a Sigma ART. However, it's also a lot smaller than an ART.
I like it for the size, the focal length, and how it renders once you're past F2.2 or so. And wide open is usable once ISO hits a certain point.
Zeiss Milvus 50mm f2.0 zf.2 lens. A lot has been said about using light lenses on the d850 camera which in a way does not make total sense. I use lenses that produce excellent images, do consider weight, but image quality is priority. I'm old but try to keep in good physical shape to where I am not handicapped.Putting a light 50mm on a D850 reminds me of the guy who orders a 3000 calorie meal but ends up ordering a sugar-free drink to save 100 calories.
Best way to stay with a heavy camera set-up is to never even try a light one. If you do and go back to the heavy one, then you really notice the difference.Zeiss Milvus 50mm f2.0 zf.2 lens.

This is what I mean: (View at original size)When you say "soft" are you representing that if you shoot wide open and pick single point AF on whatever that point will not be in precise focus because the lens is simply not capable of achieving precise focus?



One detail to consider with this type of 45 degree test is that although AF should vertically detect the fairly thin horizontal darker line - the vertical AF detection line usually reaches beyond the boundary of the thickness of the horizontal line.
The purpose of the comparison was not to assess AF accurracy, it was to show that the sharpest plane of focus is relatively soft at f/1.8 and that it was not because of focus accuracy. The slot you see on the left side of the target is where I put a vertical target when I am testing focus accuracy. However, when I have compared this slanted target that I adapted for macro lenses, with and without the vertical target, the results have been essentially identical. The targets are rather small so this is really a good system only for close focus distances.One detail to consider with this type of 45 degree test is that although AF should vertically detect the fairly thin horizontal darker line - the vertical AF detection line usually reaches beyond the boundary of the thickness of the horizontal line.
One reason for having an AF test subject parallel to the sensor is that starting AF from infinity the "target" can be detected before it is located in the centre of the AF detector - indicating some back focus that would not happen if the target was parallel to the sensor.
Similarly when starting AF from minimum focus with a target at 45 degrees some front focus can be indicated that would not happen with the target parallel to the sensor.
That may be true for cameras, but it's not for lenses. May be true for the first few lenses one buys, but eventually, if you keep buying lenses, you tend to wind up with every lens being a 'specialty use' lens. Let's say you have a 70-200 F4 and a 70-200 F2.8. You would use them for different purposes. Have a zoom and a collection of primes for the same range? Bet you would use the primes in one situation and the zoom in another. Going hiking a lot? Probably bought the camera with that in mind.Also another thing to consider is that many folks don't buy equipment just for one situation. E.g one camera for when it's raining, one for when they travel, one for short distances that's heavier etc. Many use their equipment over a broad spectrum of uses, so I wouldn't be into buying another camera line just for hiking.
I have a 70-200 2.8. I use it for work where I take the car to and walk about with it. I also climb up mountains with it. I use that 2.8 aperture. I wouldn't give it up for the f/4 despite the weight because that 2.8 really matters, it's all priorities of what you need the equipment to do. But I might be less likely to lug a 50mm lens that weights the same as a boat anchor around when I am stopping down to f8 anyway, and as you say, can use the perfectly sharp (at that aperture) 1.4G right?That may be true for cameras, but it's not for lenses.

My daughter (non-photographer) needed a better camera for an upcoming hike two summers ago. She bought an iphone. Anything bigger was simply too heavy. Her hike: Pacific Crest Trail, Mexico to Canada, 143 days, solo.
When it comes down to it, due to the lack of depth at an f1.4 there's very few situations that you need an f1.4. Hardly any lens will be at its best wide open. I chose a Zeiss 50mm lens with an f2.0 aperture and a Tamron 45mm with an f1.8 aperture and I am not missing a thing. Most 50mm lenses aren't that heavy.I have a 70-200 2.8.

I'm on the fence with swapping my Nikon 50mm for either the Zeiss Otus or Milvus. But, BUT I certainly like the AF that Nikon offers and the setup is my first slr. Sooooo I kinda' don't know what to think. Your thoughts, please, on getting an MF quality lens.When it comes down to it, due to the lack of depth at an f1.4 there's very few situations that you need an f1.4.

This is not always so - though likely with a lightweight F mount lens - but the 50mm Z does not fit onto an F mount body.The purpose of the comparison was not to assess AF accurracy, it was to show that the sharpest plane of focus is relatively soft at f/1.8
The question I was addressing was about my Nikon 50mm f/1.8G lens, not about all lenses.This is not always so - though likely with a lightweight F mount lens - but the 50mm Z does not fit onto an F mount body.The purpose of the comparison was not to assess AF accurracy, it was to show that the sharpest plane of focus is relatively soft at f/1.8
If you want to shoot any moving subjects, then probably auto focus is best. That's why I have the Tamron 45mm f1.8 lens. A manual focus lens is best used at live view to get the focus on the money most of the time. The digital cameras just don't have the excellent screens that the old film cameras had for manual focusing.I'm on the fence with swapping my Nikon 50mm for either the Zeiss Otus or Milvus.
