Hi Simon,
Hi Simon,
The specs on the Sealux look very good. I had already ordered my Endeavour when the Sealux was announced otherwise it would have been a serious contender.
I was concerned about the monitor on the Endeavour, but it turned out to be just fine. I would recommend a dark mask if filming in bright shallow water to reduce reflections.
Ron is right about the flip filters. It would be nice to have both. The Endeavour is really set-up for the Phenom 94 degree port and there is not enough room for two filters and keep the optics perfect. The lens is convex on the back. If you have a flat port, it is easy to remove the filter from the holder and fit a dioptre. You can then fit a thin CC filter to the front of the camera. The camera will MWB through the filter in daylight or with u/w lights.
With the 94 degree port and the supplied weights the Endeavour is perfectly neutral, although as the lens is slightly offset to the left (to accomodate the handle of the camera) it does tend to tilt a little to the left. I need to experiment with the weights to see if I can correct this.
I look forward to the Sealux report.
My wife was looking at the D300, but as she already has the D200 she decided the increase in performance doesn't justify the expense. She has changed to Inon strobes instead. We are off to Manado in two weeks for the Asian Shootout so looking forward to some macro stuff
