    Re: How useful are the monster teles?

    A couple folks tried this, including one person who tested with his 150mm f/2. They were doing it without electrical pass through (a la modified EX-25), so the lens had to be powered off while...

    Re: SWD Lens vs non-SWD Lens

    Anyone want to submit theirs to the screwdriver?

    More seriously, I'm not sure if the 90-250's introduction dates from before or after the original ultrasonic motor patent's recent expiry, so if it...

    Re: SWD Lens vs non-SWD Lens

    I grant that until we hear from Olympus, or the lenses finally launch, we won't know anything for sure. But your analogies don't quite fit with this circumstance. Rather than a family of products...

    Re: Ultimate Lens Test, ...... and the OM 50/1.4

    It might be easier for northerners, since we only only have reasonable hours for viewing of sagittarius for a few months a year. At a high latitude, waiting for much of the interesting stuff to creep...

    Re: SWD Lens vs non-SWD Lens

    FWIW I think the first option is so unlikely as to hardly warrant mentioning, especially since I've seen at least a half dozen hysterical posts concerned that Olympus would choose to do this, yet no...

    Re: Experimental AF confirmation with manual lenses

    Unfortunately nothing there is either surprising or widely useful. At best implementors would have to sacrifice one fourthirds lens to chip one third party lens, and the chip would still communicate...

    Re: Plastic Insert for Hotshoe

    This could be important given the especially low triggering voltage Olympus flashes use, and the relatively low voltages used by almost everyone else nowadays. I'm not sure a hot shoe cover is the...

    If you use a later FL-series flash there's actually a little pocket inside its soft pouch to (more or less permanently, if you're like me) store the cover in. As much as I appreciate the clever...

    Re: Camouflage on paint

    Per bugguide, we can tell this is a female, as it lacks a stridulatory area (for singing) on its back.

    On the odds it's either a greater or lesser angle-wing, though there is an outside chance it...

    It's a katydid of some sort. Your location would help to get closer, but bugguide should get you started.

    Re: Hartblei tilt and shift lens

    M42 would probably be the safest bet, but 35mm (short telephoto on fourthirds) doesn't often demand perspective control, and unless you're doing macro f/2.8 won't usually have a thin enough DOF to...

    Weevils are slow to start with, which helps some. It was also chilled, which puts most insects into a short lived torpor. When I'm done focusing I turn off the modeling light, as it tends to both...

    Agreed. Especially since Olympus charged an initial premium for that camera surely it deserves a mid life update! I want the exposure compensation preview, to give control of the live view's gain...

    Stacked weevil.

    This is 29 frames stacked with CombineZ. It looks unreal, but it's one way of gaining DOF without suffering excessive diffraction from high f-stops.

    The lens magnification was about 2:1 (OMZ 80mm...

    It's hard to judge the glass, but everything else looks identical. In particular, within a product line, the coatings are the same colour as the locally available ones. It's hard to fake the coatings...

    Re: Lens Filters

    Personally I'd choose a clear filter over a UV one as traditional UV filters do affect colour balance slightly, and the UV block effect is not needed with digital sensors.

    Re: Extension Tubes ?

    It's very desirable to maintain electrical connections on fourthirds lenses, so traditional extension tubes are not very useful with them. They will work fine with manual lenses, but since the...

    Re: Zuiko 8mm Fisheye The Good & The Bad

    My bad on the size, the ZD is a lot heftier than I recalled. That only improves my guess that low dispersion glass was deemed too expensive to use, however. Most QC issues won't show the same...

    Re: Zuiko 8mm Fisheye The Good & The Bad

    That sort of lateral colour is usually a result of design compromises rather than sample variation. It seems to me the ZD 8mm FE was made on a whim, and wasn't considered worthy of the finest...
