    New OM-1

    Japanese is a language where words can change meaning, often significantly, with context. The manual may have been translated well but the menu terminology can put the cart before the horse. This applies to many japanese products (and german too ) where the meaning can be reversed. I do have...

    New OM-1

    The white boxes are the detection. The AF-On does the same thing as the half-press shutter. The shutter button and half-press can be configured in several modes, changed through the menu (unfortunately the manual written in japlish, can seem volte face, menu can show "off" when it means "select...

    Olympus OM-D E-M5 Mark III System Camera with 14-150mm II Lens

    Rather over-priced. There are a lot of E-M5 III changing hands under £700 and the Olympus M.Zuiko Digital ED 40-150 mm F4-5.6 II for around £80.

    New OM-1

    Actually not at all and please consider that I am somewhat over qualified to test and assess cameras or any other form of radiation detection equipment. I endeavour to take test results from qualified sites where the methodology can be checked. The OM-1 has a stabilisation system that is...

    New OM-1

    Yes, but if you look at the Photon To Photons charts, the new OM-1 sensor is not significantly less noisy than the G9. Probably some other parameter. I'm retired but used to testing and assessing radiological instruments, mostly photon. Light is photon. Mike Lane demonstrated a simple noise vs...

    New OM-1

    The read-noise chart above may not be easy to understand, this may be better. The charts consider different things, electrons and DN (Data Numbers aka Analogue to Digital Units (ADU)). As a radiometrologist I tend to understand the electron chart better. Same source, Photons To Photos. It shows...

    New OM-1

    The noise levels of the G9 and OM-1 are very similar. I like to restrict the G9 to ISO 3200 but will let it go to ISO 6400 without fear. If the light has good contrast but dim it can be acceptable at ISO 16000 - it depends on the light.

    New OM-1

    I have found over quite some years now that Adobe Camera-Raw, Photoshop and Lightroom introduce artefacts to Panasonic and Olympus because they ignore the sidecar files in the extended-raw. Whilst Adobe probably work well for Sony, Canon and Nikon, there have been many complaints of failing...

    Yes, telephone numbers have 5 of more digits ;)

    New OM-1

    It's DXO Photolab 6 now. Problem is all such software need paying for upgrades. Photolab probably has the best de-noise but then you only need to de-noise if you have noise - and MFT probably have the quietest read noise (see over at "Photons TO Photos"). MFT show little noise up to ISO 6400...

    New OM-1

    I only use Workspace for basic functions, reading the SD, updating camera. I do not use it for raw conversion, the camera does that job better. It does show information. To be honest I lose my patience with raw-converters and post-editing, I can usually get a better jpeg out of the camera than...

    Any tips for trees, shrubs, or other features that attract chickadees, nuthatches, and woodpeckers rather quickly?

    Dunno, here rats are mainly associated with farm barnyards, feed stores, hay, chickens and cattle, but not pigs as pigs kill them. Anyway, imo it was the local council not getting a handle on waste collection, putting food scraps out for fortnighly collection in biodegradable bags throughout...

    U.K birds that are common on the mainland but very uncommon/ rare on our islands. .

    Dippers are not particularly shy and are fairly easy to find in North Wales. Fast flowing rocky streams. Yeah, devoid from south of England.

    Any tips for trees, shrubs, or other features that attract chickadees, nuthatches, and woodpeckers rather quickly?

    Unwelcome rats are attracted to excessive spillage and food waste (we had a problem with houshold food waste not being collected often enough and only bagged so not kept in rat proof containers, sorted). If there is a lot of waste rats will get there before ground feeding birds and the...

    I don't mind our squirrels. They'll figure out any obstacle, dive off the fence or the hazel tree. They don't drive the birds away. If you give them a few nuts they ignore the hanging feeder cages. This baby was as cute as a button. The boar is as big as a cat.
