    lol, that's my biggest fear. still being inadequate with a flash, but it's a start!.

    the 58 flash does integrate a bounce card (finally sony!), that helps a BIT. And for a single flash, a large diffuser would probably be necessary. Clearly, I have no idea what to expect though. This should be interesting.

    How long do those batteries last you in your 42? They seem a bit on the weaker end in comparison to the ~2000+mAh batteries now.

    Hey ... don't interpret this improperly.

    The pop-up is an emergency solution, ONLY, in my opinion. It often results in "red-eye", seriously hard shadows and wash-out. The pop-up is best left to triggering other things wirelessly, but that can be a challenge due to synchronization delays.

    The '58 is your best bet, of all the standard ext. flashes.
    The '56 would be the next
    '42 next
    '36 next

    bought in groups, though ... the '58 and the '42 marry up, call them "Phase II"

    the '56 and '36 do so, likewise. Call them "Phase I" and have been superceded by "Phase II" flashes.

    If you only had one flash to buy, to start the ball rolling, forget "Phase I" flashes and go directly for the '58 flash. You can quickly add the '42 to get slave operation. The '58 gives you the most flexibility and bang in your imaging. Also, the '58 will not group "phase I" flashes ... so that's a negative in any expansion plans. That's really hard to argue against, in my estimation.

    I do NOT own a '42 flash.

    Good score on your twin unit dr4gon, Man it's tempting but I just can't spring that kind of cash right at the moment. In several weeks if you still have two of them maybe I can swing it. I am going to have to figure something out as it is almost time for basketball games LOL! I am working 4-12 tonight to pick up some extra cash to apply to the camera and equipment fund. I keep thinking a 36 will be fine for me but then from what I read and hear, and suspect in 6 mo. I will be buying a 58 and going I should have just got this to start with!

    hmmm, for some reason I thought you had a F36 and a F42, guess it's the f56 then.....

    Sure I can wait and see if I still have it then. Where do you work? I recall one time you said you worked in law enforcement (police or something?).

    Unhappy Some things really need to change ...

    Yes, when I saw it, I understood a little more, also. Some thinking has not progressed much. You would think that after all the improvements that have been made in tote-technology ... sheesh! They are still using a shipping-liner. No, strike that ... an even cheaper version. The handle is of fixed length ... less than six inches tall. Now, there is no shoulder-carry capability at all.

    LOL wow how lucky we are, it's a retro re release of a vintage carry sleeve!!
    While i was typing last night i was working as shift commander at the county jail lol! I work out of adult probation but am still a part time reseve deputy. I left full time from the sheriff's dept 11 years ago to go to probation, I was a sergeant when I left, stayed on the reserves. So I can work as supervisor in the jail, or they let me because I can cause the least amount of trouble that way lol. My fun part time job is with concert / tour/event security.
    I'm from the government, I'm here to help......... be afraid, be very afraid!! LOL

    Lightbulb Lens sizes ...

    During our optics discussions ... I began looking at what would be required to have a 1000mm telephoto with a wide aperture of f/2.8.

    Remember, 1000mm is 1 full meter. So the overall lens effectively needs to be one meter in length. Yes, with additional elements or diffractive optic technology, we can physically shorten that, somewhat. Okay ... what about that first element? How big is it?

    Well, doing the basic math ... the calculated minimum size is 357.15 mm or about 14 inches in diameter. Taking into account possible light loss from the additional elements, I suspect it would be a couple inches larger. Folks, that's a lot of light gathering. Is it practical? Handheld? LOL

    Imagine ... holding any lens that extends a full meter away from your camera. Now, compund that thought with a finely ground first element that weights on the order of ten to fifteen pounds, easily. It boggles the mind. A titanic struggle to even lift the lens, let alone aim it.

    At least now you have some idea of why telescopes require sustantial support ... and the more "light gathering" capability they have, the size grows enormously.

    So ... when you are considering "bright" glass ... the longer it gets ... the bigger it gets. Real fast! Be very careful what you wish for ... and get a back brace.

    So where is that fixed SONY 400mm f/4.5 they were promising, already?

    So would a 500mm 2.8 be one half the size and weight or does the math not break down so easy?
