My response in this thread was primarily a response to Nicolo who asked for information from anyone with experience using Hartenberger strobes. Nicolo specifically asked about 625, 250 AND 125 ws models. So I don't think it is “crossing threads” to say that I think a 125 ws strobe, any 125 ws strobe, is underpowered for many wide-angle shooting situations. Fine for most macro shooting, but underpowered, anemic for many wide-angle situations.
You talk about freezing nicad batteries. Personally, I have never heard of this and would be concerned about its damaging the cells. I get about 4-5 year lifetimes from my nicad battery packs. I simply discharge and recharge the battery packs about once a month, or every two months, when I am not diving. And if Hartenberger can no longer supply Nicads, and I am forced to go to NiMH packs, a .8 or .9 second recycle time on full power, and something on the order of a half second or less on TTL is stlll significantly better than 2-3 or 4 seconds when something is happening.
I also am not particularly concerned whether the Hartenberger strobes with the Heinrichs Weikamp converter match the SB800 compensation settings or not. What I am concerned about is whether the output is consistent and predictable so that I can learn what settings work best in particular situations.
Andre Crone commented on the Seacam 250, which no longer exists. And his comments only seemed to say that it gave similar results ON A SERIES OF LAND SHOTS to the SB800. He did not give any information concerning over what range of f-stops the exposure remained consistent (and therefore predictable). He even brushed off my comment about that. But in the real world, the range of f-stops where the exposure remains constant and predictable is very important. This is exactly why the ambient light meter in a camera should give consistent exposures over as wide a range of light intensity as possible. if you only get one shot at the subject.
More predictable and consistent results mean less time in front of the computer trying to make corrections. And more time diving.
Further, using two Seacam strobes in i-TTL with Nikon cameras requires that at least one strobe be connected to the camera with Seacam’s S6 sync cable. And if someone already has a supply of the N5 cables, as I do, having to buy several S6 cables (so that you have at least one as a back-up) is virtually as expensive as the HW converter which allows the use of N5 cables.
My comments concerning Hartenberger strobes also dealt with reliability, which I feel is a very important issue when the prices are as high as they are on the European strobes, be they Hartenberger, Seacam or Subtronic. And my experience with the Hartenberger strobes span a quite long period of time, far longer I suspect than your time with Seacam strobes. Combined with fairly heavy use. Thousands of flashes per year. Year after year after year. Which is also something Nicolo might feel was relevant to his own strobe purchase decision. I am not telling him what to by, I am only giving him a much wider range of information to make his decision than you were by your just criticizing Hartenberger strobe weight.
I stick by my contention that quality is worth paying for even if it involves more weight in my check-in luggage. A live aboard dive dive boat costs $3000-5000 for about ten days. Or more. The airline ticket might cost another $1000 or more. And things like hotels and food add to that. My photo results are important to me, and I feel it is worth paying another $100~200 for an extra check-in so that I can have equipment of the highest quality and durability to work with. And back-ups of the most important gear.
