Review of many of the Panasonic GF1 MF and AF lenses. 14-45mm F3.5-5.6, 20mm F1.8 pancake, Sigma 30mm F1.4 Nikon mount, 35-70mm F2.8-4.0 Canon mount, 50mm F1.8 Nikon mount pancake, 50mm F1.4 Olympus OM lens, 50mm F1.4 Canon mount, 85mm F1.8 Nikon Mount. I am attempting to show the differences between the lenses above with respect to low light stills and video. I also show examples of how the AVC-HD light codec does against the MJPEG codec in low light situations. The 14-45mm and 20mm lenses are probably the sharpest lenses I have. However, the 14-45mm lens has poor low light performance at its telephoto end. The 20mm is always sharp and performs well in almost any situation. It is a fantastic lens but it is not cheap at 0 new. The 50mm Nikon pancake lens is bigger than the Panasonic 20mm pancake but it is almost as sharp. The real benefit of the Nikon pancake is that it is only about used on ebay. It is the best bang for your buck lens I have found.
