The bellows is großartig.Ich use him for my Sony Alpha 580, inside and out. It works great, and what I was also very important and that's why I is not resorted to Hama Dust Ex that Giotto did not smell of plasticizers. Of course it smells slightly rubber, but very pleasant. One does not think that a hands are etched equal and that alone justifies for me already the Mehrpreis.Er but is anyway stored in an extra pocket of my photo backpack. The 3 legs are really handy as the tip does not touch the ground and no unnecessary dirt at the top to hang. A customer reported that shifts the nozzle at the press. I absolutely can not nachvollziehen.Ich it have just tried again and because nothing moves. The performance of the bellows is more than adequate.
