40-150 f2.8 and high res mode EM1ii



Wind picked up as storm was blowing in - so we see artifacts and blurring in the high res image that isn't there with a single exposure. Again, don't compare till you click to see them at full res.

Pay attention to the amount of detail in the roof shingles, in the plant below the window, and the detail in the blind, and lack of grain in the high res image.

Of course, I don't need to persuade you, only satisfy myself. It takes a few minutes to load the 80 MP raw file, sharpen it, reduce it to a more manageable size and save it. No one, even Olympus, is trying to tell you there is a full 80 megapixels of information in these files. - more like 40 mp.

We saw the same thing with images from Foveon cameras. They had full information at every pixel and initially tried to persuade us this was equivalent to a bayer pattern sensor of 3 times the size - it wasn't - but the images were unusually good for their native size - each pixel full colour, no bayer algorithm guessing at colours and detail.

You don't get the normal aliasing moire in patterned details, noise is significantly lower, resolution is more than half again better than standard shooting mode - not bad for a minor effort on our part - using a tripod - which I'd do anyway for my landscape and industrial work, and a little delay in processing the image.

I'll set up an action in Photoshop for any high res images I'm interested in working on.

High Res Mode Test - 8-18 mm. Panasonic



Be sure to click on the images to see them at original resolution so you can compare - in the blog as is they are sig. reduced in size and you won't see the difference.

Olympus em1ii

Can you believe it - I own a Fuji 50s and am about to replace it with the Olympus - huh?

Well, it's like this - I'd always liked the idea of the small camera and even had a Panasonic gh2 that I liked very much but felt image quality lacked.

Recently with using the rx10 I was amazed at the image quality with a very small sensor and had to wonder about modern 20 mp micro four thirds.

I read mixed reviews of the high res mode - only with primes, more often than not not offering anything more than native single shot quality.

I'll be offering evidence soon but can tell you that high res with the Panasonic 8-18 and with the Olympus 40-150 are fantastic and this is going to be great.

Is with this camera is simply amazing. In single focus I have made some great shots of the dog - even indoors - which previous cameras have frankly sucked at.

Today at the off leash park I struggled mostly because as son as I lay down to get a low angle Sophie would bolt towards me and be within five feet by the time I got camera and telephoto to my eye  - hardly the cameras fault but I did have some success as she ran towards me standing so there's hope.

You might ask why buy the 40-150 2.8 when it weighs exactly the same as my canon 70-200 f4.

Well, I was using my Pentax lenses with the Fuji and this 40-150 will cover my 120, 200, and 300 and even gets close to the 75 so that's one lens instead of four.

A lot is made of lens equivalence - double both focal length and f stop to get an idea of what the lens does in full frame terms.

But remember that exposure and matching shutter speed are based on the actual f stop, not some equivalent number so my 2.8 40-150 will need half the ISO compared to my canon lens.

Still, I'd be kidding myself if I thought that even with high res mode I'd be able to print as big.

Know what -my printer only does 17X22 and my garage stores half a dozen large canvas prints -too big to hang in the house. I even bought a pack of 8.5X11 paper so I can make hand holdable prints.

is it possible this micro four thirds will disappoint? Possibly, but it will be fine for now and I'm definitely having fun. Someone who does need 40X60 inch prints can buy my 50s and be happy with it.

Back with images to support this position in the next few days.

Shot this with the Velvet 56 - the idea being that with an f 1.6 macro lens with flare, one could concentrate on shape and tone almost entirely. Photographed on my north facing back deck so that the soft north light (I was in the shade) would come from behind the object.

Waterton Driftwood


Sometimes there's a large selection of driftwood on the eastern shore of Middle Waterton Lake but the pickings were slim this year. I did find this interesting bug eaten stump half buried and was able to rest it against some other logs. I shot two images, one wide open to blur the background, and a second stopped down for maximum depth of field in the main subject, then blended them together.

Camera was the Fuji GFX 50S with Pentax 120 macro lens via Fotodiox Adapter.

Near Full Moon


The fun of having a 600 mm. lens equiv. in a modestly sized and affordable package.  Even 600 mm. needs a crop to about one quarter size.

Sony RX10iii



 Early Spring - not a lot of green yet.  Shot at 60 mm. which with a 2.8X crop factor is equiv. to about 175 mm., ISO 250, 1/500 at f4. this will print very nicely to 13X19.  A fun camera to use, and with results I can be happy with. Yesterday I shot with the Fuji GFX, today with the Rx10iii - horses for courses. For best assessment of the crop, click on it to see at 100%
