In January, Leica announced the re-issue of the classic Noctilux-M 50mm f/1.2 ASPH. The silver edition was limited to 100 pieces and an official Leica reseller is claiming its value has already doubled.
Earlier this month, Olympus announced its latest Pro lens: the 150-400mm f/4.5 TC1.25x IS Pro. With its high price and wavering public sentiment around Olympus' future, it was easy to question if the lens would be popular. However, Olympus looks to have oversold its initial production run.
It seems that demand for the new Nikon D850 is huge. So huge, that if you pre-order the camera now, you won't receive one in the first batch that's released on September 8th.
