The first floor is packed with booths stocking all the big brands - Nikon, Canon, Sony et al, but those who remember it will know that Rolleiflex is the brand to be reckoned with. This revered company falls well into collectible status and older models are particularly sought after. Head to booths A-9 and 2 on the ground floor and you'll be looking at prices between 2,500 and 10,000RMB (based on age and condition) for a classic Rollei. For Nikon (or indeed Canon), try the 'Nifty Fifty', a fixed 50mm f/1.4 lens; its wide aperture is ideal for portraits and low-light conditions. We found one at booth A-20 for just 1,500RMB.
