While there are a lot of shoulder mounts and follow focus available on the market, the options regarding viewfinders are quite limited. Everyone I know love their Z-finder and those who dont have one wished they did and complain about the price.
Well, the Z-man listened and thanks to pressure from competitors (LCDVF anyone?), they just came out with new iterations of the product divided into two product line: the Jr and the Pro. The differences are explained in the chart below (taken from Zacuto web site).
First thing we can notice is the change in z-finder to camera attachment. The new system looks much stronger and will probably give more confidence to those who were afraid of the clip system used in the first system (which never gave me any issues). Zacuto also added a lens tube production boot and cap which is a great idea since I had to design one on my own.
I hope to put my hands on one of these soon to give you a side by side comparison with the existing model.
