When using anamorphic...

hello everybody.

One quick question. if i buy the AG-LA7200 anamorphic adaptor and position the zoom at the widest focal lenght. will i see too much barrel distorsion or dark areas in the corners?

Where can i find a captured image on the wides zoom position?
And if i am not wrong, the magnification of this lense is 0.8x son at wider postiion the dvx should have around 26 mm (equivalent to 35mm), right?

There is no vignetting (dark corners) at full wide. There is some quite noticeable barrel distortion when at full wide.

It's not .8 magnification, it's actually .67. The anamorphic fits 33% more into your field of view.

It will only work in a limited zoom range on the XL1s. Anything past about 45mm will be quite difficult to get in focus.

Also, will be there less depth of field, since you are using a larger focal lenght to get the same shot, right?

This will increase cinematographic look.

Yes and no. Mostly no.

The anamorphic is wider, so you do need to zoom in a little bit to maintain the same framing, which would give you shallower depth of field. But in order to get the lens to focus accurately you usually have to stop down a few stops, which will deepen the depth of field. In most circumstances DOF will be deeper with the anamorphic attached.

Not if you want it in focus. The way that I use the animorphic is that I just use it on long and mid shots. Any closeup shot such as facial expressions or just something that requires a very shallow depth of field, I shoot in 4:3 and crop in post. For really tight shots, the cropped footage holds up quite well and is very detailed. Sure this is not ideal, however it works well and the longer and midrange shots benefit greatly from the adapter. Thanks again barry for your Anamorphic guide, I take it with to all my shoots.

Would this image be possible very near focus and the backgorund outfocused?

If set the iris to 8 or 11 i would loose the effect, becasue everything will have focus.

You cannot shoot with the anamorphic adapter at Z80 and f/2.8 and expect it to be in focus. You have to zoom out to about Z60 before you can open up to f/2.8, and even then you have to be focused near infinity.

If you want to understand all the issues involved, I suggest you order the guide in my signature line. I can try to spot-answer questions, but it took me 20 pages to explain everything about the anamorphic adapter, which is why the guide is available.

The image that you posted is a very wide angle image, yes you would be able to get an image like that with the anamorphic. You can definatly have the iris wide open when zoomed all the way out.

Filters for AG-LA7200?

Is Panasonic's 16:9 lens threaded for filters?

There are no threads. It's a rectangular front; lens threads are not possible.
