Bit of a geek-out post this!
Sigma have announced a new 35mm f/1.4 lens. Priced at $899
Nothing massively interesting there – although I would have hoped it would be cheaper – mind you – Nikon 35mm f/1.4G is £1299!
BUT the funky-doo-dah thing is that you can buy an optional part that allows you to connect the lens to a computer! Not to take photos of course ,as this would need an imaging chip – but to update the lens itself! i.e. adjust the internal lenses, updating firmware etc! Some cameras have micro-adjustment settings to fine-tune them per lens – but this means you can do it directly to the lens without including the camera – which I guess should mean that it will be optimized for all cameras. I didn’t even know lenses had firmware! Updating is done via the software Sigma optimization Pro.
