Ok Z5-fx1000, great cameras BUT when I try to make close up to bride or grom,the camera gets very dark.

This never happen to me with my pd-170.

Do I miss something during my set up to my Z5?? any tips and tricks to this SITUATION??

Thanks Franklin

are you zooming in or walking in and getting close?

If you're zooming and are on automatic mode the iris will close as the lens zooms in no matter which camera you use. Put the camera into manual mode and lock up the exposure. Just like the 170.

Franklin, even if in manual mode, when you do an extreme closeup, as I like to do, the iris closes up to 3.4 and there is nothing you can do about it. It stinks.

The phenomenon is called lens ramping or f-drop. The PD170 had it as well, but to a much less extent and it did not interfere with my extreme closeups.

I didn't know anything about it when I bought my Fx1000 and I too was shocked when trying for an extreme closeup.

Unfortunately the only real solution to our dilemma is to use a camera with 12x zoom down front, if that is where you are trying to get your closeup from, as I used to do.

Part of the problem is the cam starts out much wider so you you have to zoom in all the way for the extreme closeup, but by the time you have zoomed in as much as you need to the iris has gone to 3.4, and you cannot open it any further with manual adjustment.

Jeff, what about hitting say +6DB? i know this is not what u want by maybe worth a go

Yes, pumping up the gain is the obvious thing but it isn't the same, as you say. I just don't go in as close and I don't worry about it.

oh oh,Houston we have a BIG PROBLEM,for weddings(including the roller S),this is serious !

Sometimes we need to sacrifice other god points!!!

Have you guys tried to lock the IRIS to 3.4 from your wide angle view before zooming?
If you do, it should stay at 3.4 thus keep the same exposure from wide to full telephoto.
Its the only way to do it or you just zoom it in, lower the shutter speed (or db boost) and record.

3.4 is too little exposure. If we were going to shoot a wedding at 3.4 exposure in order to accommodate the lens ramping we would be better off with an FX1 or Z1.
