a NORMAL adapter is basically just a tool to connect ur Nex E mount camera to third-party brand mount lens(with no additional features, it disable all electrical-related feature from the camera to the lens like autofocus, aperture settings)

there are adapter that come with add-on features like autofocus for third-party lens & aperture settings.

recently, there is one with reduce focal length & increase maximum aperture. (The Metabones Speed Booster - which makes our NEX camera to act similar to a FULLFRAME camera focal length & better control of our aperture)

Hope my noob explanation is clear enough. Welcome all the Sifus to elaborate on my explanation

p/s: google is your best friend

I'm looking for a one-lens solution. But SEL24F18Z & SEL35F18 is over my budget. Sigma 30mm f2.8 & 19mm f2.8 sales are over...

So, I'm getting the Sigma 28mm f/2.8 macro legacy lens in ebay, around RM200~300

Sigma support many lens mounts, try google it... im eyeing on the Konica AR mount, coz i already have a Konica AR 50mm f1.4 legacy lens.

ic

try find those legacy lenses in ebay(or taobao). u can easily find a good condition one with affordable price (compare to the modern lenses)

nice lenses u have

try Taobao, if you know reading mandarin. We have a few middleman services for Taobao in LYN
