I m still using my faithful Canon 400d that I bought in 2007 (I think). Recently though I am wanting more in less than brilliant lighting conditions. I ve got my head around the "exposure triangle" and still I m lacking the sharpness in landscapes that I see from others images. So do I save and upgrade the camera....but that will no doubt end up as a kit with a similar lkens to the kit lens I m using now. Or, Do I go for a 50mm prime lens and if so what Canon fit lens ? Any thoughts ?
