Messier Object

A perfect optic will render a point source as a 'clean' Airy disk with its characteristic concentric diffraction rings. To suggest that the diffraction rings are some sort of artefact caused by the ...

Olympus bought some high end DSLR kit and went out birding with a pro wildlife shooter. And when they got back to the office they finally understood what they needed to produce in order to be taken ...

So you expect a user to fiddle with the diοptre setting every time they use the camera :-) No the shutter mechanism is fast, push lever down and it snaps closed, push lever up and it snaps open. ...

I don't think it matters to sports and wildlife shooters whether it is 9, 10, 15 or 18 FPS, just so long as the  camera acquires sharp focus  in the first frame and holds it to the last frame. 18 ...

Yes, but it needs to be understood that CA removal in PP merely changes the colour saturation of the aberration. The aberration is still there causing loss of edge sharpness and clarity.

A simple lever action mechanical shutter will 'fix' it provided the user remembers to close the shutter when not shooting. Several DSLR models have/had it including D700, D800 and the Olympus E-5.  ...

If you can remember the shutter on the E-5, a vey simple mechanism with a tiny lever on the side. I never used it, but just looking at it now it seems the perfect solution. I guess Oly does not ...

Olympus does not direct-sell cameras or lenses in the OP's country.

No stores here that  I can see Mark. I suggest you check with Digidirect. I think they  have a store in outer Perth, and the usually do pre orders on popular new cameras. They mightbhave some ...

you are correct, they said this year, and there was no mention of any delays caused by the earthquake.

Some beautiful shots, especially the hummer in flight, and some good action. Well done Bob Peter

beautiful colours and composition, well done Milt Peter

They all look good on my monitor Bob. Even at the initial displayed resolution I can see they look good. Peter

well done Dennis, Excellent catch ! I've waited and waited for this bird, only to have it run past me not 2 metres away. Peter

Last week our intrepid little wren climbed a mountain, this week he continues his adventure by exploring the rugged shoreline. Peter , A vantage point, looking for the best route . A quick pose for ...

A bolt on adapter, Olympus would be horrified. I mean, how would we mount our m.43 lenses ? Maybe we won't then want to buy m.43 lenses . But seriously  my biggest problem with adapters, especially ...

Canon DSLR at the moment is my primary camera system: 5D3, 7D2,  300mm/2.8 L IS II,   100-400mm L IS II,   70-200mm f/2.8 L IS II,   24-105mm f/4 L,  16-35mm f/2.8 II, Sigma 50mm f/1.4 Art,   Sigma ...

Ray I did find an MTF chart for the 300/2.8 and at f/2.8 it is marginally less sharp near the edges than the 300/4 at f/4 but definitely nothing that any human eye (IMO) would be able to discern ...

sorry for the delayed reply. . . my EF lenses are primarily for my Canon DSLRs, FF and APS-c.  The M5  being APS-C does not offer me anything new other than that it's Mirrorless. Whereas the E-M1 ...

I still find it a little amusing that for such a long time PDAF was looked upon here as old tech. I wonder if Panasonic and Olympus might now follow different paths for AF and what that might mean ...
