Which Sony lens provides the sharpest results for landscape shooting?

Like someone mentioned, those kit lenses really dont do the A7IV sensor any justice. If you want to avoid that mushy garbage in the corners, I have been incredibly satisfied with the Sony FE 16-35mm f/2.8 GM II. It is easily the sharpest wide zoom Sony has ever put out.

• XA elements: These basically eliminate the edge-to-edge resolution problems you're seeing.
• Nano AR Coating: This is essential for Zion since you'll be dealing with harsh light bouncing off the canyon walls.
• Weight: Its way lighter than the version I glass, which matters when you're hiking all day. You might also look at the Sony FE 12-24mm f/2.8 GM if you want to go crazy wide, but it doesn't take standard screw-on filters easily. The 16-35 is just a better all-rounder for a big trip like this. Let me know if you need more details on how it handles flare!

> the corners are just mushy garbage and it totally ruined my shots In my experience, if you want absolute sharpness without wasting money, the Sony FE 20mm f/1.8 G is incredible. I've tried many lenses and this prime often beats the expensive zooms for edge-to-edge detail. Zion is perfect for a 20mm focal length. Its way lighter than a GM lens too, which youll appreciate while hiking. Definitely a better value for the quality.

Honestly, I was pretty disappointed with some of the earlier zooms because they just didnt hold up under pixel peeping at the edges. Unfortunately, those kit lenses are a total waste of a good sensor. If you want the absolute peak of technical performance and resolving power for that A7IV, you need the Sony FE 35mm f/1.4 GM. Its MTF charts are basically a flat line at the top. It has almost zero field curvature, so those corners stay tack sharp even wide open. If you need wider for Zion, the Sony FE 14mm f/1.8 GM is another beast. Just keep in mind that even with great glass, shooting past f/11 starts introducing diffraction which softens the image. Definitely worth the investment to see what that 33MP sensor can actually do... hope you have a blast in Zion.
