  • The E-M5iii has become my favourite street & travel body. For street I use either the PL15 f1.7 when I want to be really compact and under-the-radar, or the Oly 17 f1.2 for more serious use ...
  • Replied in RTFM
    The ‘flippy’ rear screen.
  • That is usually perfectly correct, but if your subject suddenly presents itself, for example, further away than your snap focus setting will give adequate depth of zone focus, or if your creative ...
  • >> Because we were traveling between private preserves by small planes, we had very severe weight limits. The equipment I took did make it under the "carry on" limit. As it turned out, we were ...
  • Yes, quite. I’ve got a fully paid-for Kenya trip with Wild-Eye sitting currently delayed until October ‘22, and goodness knows whether I’ll be able to go (or if that wonderful company will still be ...
  • A few varied comments: 400mm at the m4/3 long end I’ve found fine in the Kruger: I am a bit of a birder, but I’ve only been to reserves there where off-road driving is allowed. Personally I find ...
  • I do exactly the same. Simple, low hassle, and I could crack through dozens of slides while watching Netflix with my wife in the evening! There are some good offers on the 30mm at the moment, but I ...
  • I found the Laowa 7.5 to be soft at all apertures and it had a strange, brown colour cast. That’s with a full spectrum E-M10ii with a screw-in Hoya 720nm filter.
  • I find Olympus and Panasonic lenses (including the Panny 8-18mm) get a lot of IR diffraction softening when stopped down more than to f5.6. I assume this is related to the longer wavelengths of ...
  • I’ve snapped a series of images when I’ve packed things up to send off to purchasers, but I hadn’t thought of doing it on ones on arrival. Especially one from a commercial supplier. I’ll be bearing ...
  • Another m4/3 IR and full spectrum resource: ...
  • Tesni is an excellent workshop leader. I’ve done 2 U.K. wildlife workshops with her, and she works full-time on advising her students - worth every penny in my view. She switched to Olympus from ...
  • …on an IR or full-spectrum converted body? any first-hand experience much appreciated. Thanks.
  • Yes, and there’s experimental trial evidence for dark colours attracting more mosquito bites (I think the studies were done in SE Asia).
  • Depends on what ones after, I’d say: define ‘better’ 🤣 Both have some unique features: for example, I love classic rally cars, and the Festival gives you the opportunity to hike out in the woods ...
  • Well, I’ve just compared my E-M1iii with the 45mm f1.2 against my E-M5iii with the 17mm f1.2; both with electronic shutter continuous low at 10fps, full aperture, handheld Auto IS (I couldn’t ...
  • Yes, I agree. If I’m going anywhere away from home with any m4/3 gear I usually drop the 12-32 in my bag as a general backup. It’s my main lens when I take the GM5. For me it has the additional ...
  • Very nice. I’ve been half a dozen times to the Goodwood Festival of Speed, but not yet made it to the Revival: I keep telling myself I must remedy that!
  • Replied in Why?
    Great - I do medicolegal expert witness work, which has moved largely online for the moment. Although I’ve had a lot of professional meetings over the system, I haven’t had a case go to online ...
  • Replied in Why?
    True, but a proper camera with a m4/3 sensor or larger gives enormously higher quality images, nice shallow dof and a choice of fields of view. If one's doing it professionally it suits much ...
