Honestly, just go with the Sony FE 35mm f/1.4 GM. I have been using it on my high-res bodies for over a year and I am super satisfied with how it handles that 61MP sensor. You are definitely overthinking the clinical look thing... it has plenty of character but stays reliable which is what you need. Since you mentioned hiking near Bend, carrying that Sigma brick is gonna ruin your day. Trust me, I have tried heavy setups on trails and you just end up leaving them in the car after a few miles. Here is why it works so well for me:

• The linear motors match the a7R V autofocus system perfectly.
• Weight is manageable for long days on your feet.
• Sharpness is great edge-to-edge even when you shoot wide open. I have never had a complaint about the images looking too perfect or whatever. It just looks professional and works every single time. If you want to actually enjoy your coastal trip and get keepers of your friends moving around, the GM is the safest bet. It wont feel outdated anytime soon.

> I am torn because I dont want to buy the Sony just because of the name if the Sigma is actually gonna make those 61 megapixels sing more but then again I am worried about the weight for long days on the trail. Unfortunately, the Sigma 35mm f/1.2 DG DN Art is a complete liability for your hiking trips. I had issues with it on a high-res body last year; the weight distribution is so front-heavy that it becomes exhausting to carry on a strap for more than an hour. Performance-wise, it was not as good as expected in terms of autofocus consistency. While the bokeh is pretty, the hit rate on moving subjects just isnt reliable enough to justify the physical tax on your body. It is disappointing that the Sony FE 35mm f/1.4 GM is basically the only safe bet for that 61MP sensor, but there is a reason everyone uses it. You need those dual XD linear motors for the Sony a7R V to actually do its job. If the price tag is the main hurdle, you could look at the Sigma 35mm f/1.4 DG DN Art which usually retails around $800, but even that is a step down in weather sealing and focus speed. My advice is to stop overthinking the character of the lens. You can always add grain or soft glow in post, but you cant fix a shot that the AF missed because the lens motor couldnt keep up. Stick to the Sony GM for the coastal trip. It is the only way to ensure your files stay sharp enough to actually use those 61 megapixels.

Late to the party but I went through this exact same crisis when I jumped to the high-res bodies. I used to be all about that heavy glass life because I thought character was everything. I had a beastly f1.2 lens once and while the images were pretty, my back was absolutely trashed after a day of hiking near the coast. I think the whole clinical rendering thing is mostly just people being picky on forums. When you're dealing with 61 megapixels, the biggest challenge I found was actually the autofocus keeping up. IIRC, some of the heavier third-party glass uses older motor tech that can hunt a bit. Not sure if it's still an issue, but maybe look into the f1.8 category if you want to save weight? TL;DR: Don't underestimate how much you'll hate a heavy lens on a trail. Fast AF is king for that sensor.
