40D eigenaars die één van nieuwe zoomlenzen van Sigma aanschaffen: opgelet want probleempje met de eerste reeks, dus best serienummer controleren:
Notice to Canon 40D owners using Sigma’s APO 120-400mm F4.5-5.6 DG OS HSM or APO 150-500mm F5-6.3 DG OS HSM for Canon fitting
When the Canon 40D digital SLR is in AI Servo AF mode, and the APO 120-400mm F4.5-5.6 DG OS HSM for Canon or APO 150-500mm F5-6.3 DG OS HSM for Canon lenses are attached to the camera with the OS function switched ON, the number of continuous frames per second will decrease.
To overcome this, we will start supplying a free-upgrade service to our customers from today.
We deeply apologize for any inconvenience this may have caused to our customers.
