Hi all,
I've been amateur/hobby photographer for the last 7-8 years, I was using APS-C dslr cameras, then had a switch on a full frame (Nikon D800) and was using it for the past 4 years. I just got myself Sony A7 III and Tamron 28-75 2.8 G2. The portraits I took are stunning, tack sharp, just amazing. But there is some issues with the landscape, I tried taking a shot of landscape, f 7.1, 1/160, ISO 100, focused 1/3 in to the scene, and the mountains behind were soft, like really soft. Did anyone have issues like this ? Am I forgetting something or ?

P.S
Glad to be here guys and gals!

Welcome.

A third in is only a rule of thumb, to be spot on, there are calculations and a tripod needed.

Atmospherics can also be coming into play in anything other than perfect conditions.

Welcome to the forum.
I would imagine (since I have not seen the photo) that the probably causes are (1) Aperture needs to be narrower (2) Atmospherics like Dave said, or (3) maybe those mountains are just so far away that you are focusing on a point that is too close.
