From Sigma:
Can you think of any other reasons why you would want to leave such a large front element unprotected? Also, can you spot another notable difference in the lenses pictured above, aside from the missing lens hood? My guess is that at least one of these pictures was taken earlier in production, when the final design hadn't been fully estabilished. [Sean]
Front Conversion Service: Service OverviewI can't help but think that very few people will be removing their Sigma 14-24mm f/2.8 DG HSM Art's hoods, but the option is available for those doing "multi-camera work."
To support the needs of virtual reality creators engaged in multi-camera videography, SIGMA is offering the new Front Conversion Service for the 14-24mm F2.8 DG HSM | Art lens . With this service, SIGMA converts the petal-type hood of the lens to an exclusive round component that lacks a light-blocking function. The new front helps prevent the lens from interfering with other lenses or from casting a visible shadow during multi-camera work. This is a for-fee service performed exclusively by SIGMA. Use of the service has no impact on the validity of the product warranty.
Cost, service time and warranty depends on each country and territory.
Please contact your nearest authorized SIGMA service station for more information.
