Based on your profile, you are already shooting 35mm. Is the equipment you are now using not meeting your needs for landscape & people pictures? If you are still frustrated with your camera’s metering system, turn it off and use the Sunny 16 exposure guide instead.
Replacing your current 35mm equipment with different 35mm equipment may or may not solve your problem. For example, if you are dissatisfied with the detail captured in 16x20 inch prints, a larger format camera may solve your problem better than a different 35mm camera.
