How many aperture blades?
« Reply #20 on: July 28, 2007, 04:46:39 pm »

Just a question, the older Schneider AF lenses will still function in AF on the Hy6, right? How are the new lenses different? Are they totally different lenses, or is the AF upgraded, or are they same in all but name? I really have no idea about them...

The new lenses are designed with digital in mind,hence AFD!
Can't wait to try them.

From the little I can tell with this early prototype, AF is faster, quieter and more decisive than my AFDII, H2 or Contax.

It is not Canon, but then Canon is not an AFi either  

Bokeh wise, here are two samples at f8 and f4.8 with the 80mm:

Thanks Yair,
Can't wait to try it myself.

Dear Andre,

here some first hand experience on the AF function of the Hy6, from "khun-k" who had the opportunity to test the camera for a portrait/beauty shooting:

Post NĀ° 45

If you are interested to see some sample images, I think khun_k has some nice portraits.

And from my experience with the Sinar Hy6, I can say that I have found the AF much faster than on the 6008 (it is in fact a completely new and different AF), and certainly also faster than on the H.
What is certainly and in some cases very helpful, is its integrated auxiliary red-light beam
for AF metering in low-light conditions: this beam of light does not just light up the scene, but projects as well a structured pattern to help the AF.

Best regards,
thierry

Since you are one of the very few right now with access to this camera and lens could you please share some light on the auto focus performance. My experience with the 6008AF was horrible. The 80mm was very squicky noisy and searching forever for focus. Full body shots were never sharp. I had the P20 combo. Replace it twice, sent it for adjustment to Rollei 3 times and finnaly gave it up. As much as I like Rollei I have to say it AF was far inferior to HassyH. Any improvements???

As EPd already said there are more factors to the bukeh besides the blades

here are some links to look at especially with samples (in english):

you get 2 indepth books about these themes at Merklingers

and here is something additional for the defocusing freaks amongst you all:
