Sorry Guys I wasnt notified of the replies..
I would drop the D2000 from consideration. You have the power of the S2000 compact in the full body size of the Z240. D2000 may have a better pattern, but for me the compactness of the S2000 trumps it. Go for either power or compactness. I started with a pair of S2000, gradually ended up with a pair of Z240's. I still use the S2000's for my macro trips. Never had a flood on any of the 4. Just look at the o-ring when you close it. You should get in the habit of visually check all seal anyways.
Thanks Watboy Yeah I'm almost at the point of discounting the D2000, but not considered the S2000, mainly as I want something to grow into and its been hard enough justifying new strobes to the financial controller
What kind of photos do you mostly shoot? If macro or close focus wide angle where you only need to illuminate the immediate foreground, the S2000 is a great choice considering you have a compact setup. That's what I've been using for years, with two different Olympus cameras, with 100% reliability no problems of any kind. A visual inspection is all you need to confirm a proper seal. But if you shoot wide angle, then go for more power. My bias tells me that the Z240 is practically a standard for good reason.
Thanks Troporobo I don't have a fixed kind of photo, it depends where I am - Mainly macro in Perth, but in Indonesia, it would be a mix - From what I can gather the z240 has some good adjustability on the lower end as well as power I can 'grow into' - the xz2 also have flash available up to 1/500 shutter speed, making the low end of power a little more useable if it doesnt go that low.
I have a bunch of both Z240s and YS D1s. Flooded a D1 when a battery (eneloop) over discharged and pressurized the cap right off, and had a friend flood one of my Z240s by user error (twisted yellow o-ring). That being said, both are great strobes and both are as good at FO as the other. The inon's have much more sensitive sensors which means that they can be much more easily used off camera on a tripod as a backlight/fill flash while using the S&S that way needs long FO cables and can be a bit fussy. S&S have had a lot of electronic issues early on with failing battery voltage sensors in TTL mode and this apparently is still going on, last week on the Bilikiki one guest had the problem with a new strobe. Overall I would go with whichever one you can get more cheaply.
Thanks Bill - They are pretty much the same pricing - it looks like the S&S are dropping pricing a little with the D2 - maybe because of the issues - I'm not 100% I want to be a guinea pig for another new design.. the advantages you mentioned again swing me to the z240..
So I think its settled.. Z240 - just now need to get the funds for the tray and arm
SO next Questions
I'm looking at the inon stick arms and grip base M with additional handle - The handles / tray don't look particularly ergonomic compared to some - whats your thoughts?
