View Full Version : Tests on my replacement EM-1

I thought I would record a few of the results from my testing of the replacement EM-1.

These shots are in Manual focus, manual exposure mode using my canon fd 200mm f2.8 under pretty grey skies

I haven't found out how to get focus peaking working with this lens yet so these were shot, hand-held with the magnification (fn1 button) set to 5X, hand-held

Test subject 1 is a pylon at around 800 metres from my house, the "full" shot is about 2/3rds of the original frame and the crop is down to around 800 pixels longest side

Test subject 2 is a sand-tower at about 400m from my house, "full" and crop are around the same dimensions as for 1


Strong purple fringing is apparent around the edges, mostly removed in LR5 but the detail and sharpness if not too bad considering the lighting.

The EM-1 handles this lens more easily then the EM-5, although I need to select a better fn button than fn1 for my magnification trigger

When the IS is activated in the magnified view it remains on eve after the shot has been taking, requiring the push of another button (doesn't seem to matter which) to cancel it

Mmm. That looks like one sharp lens.

Regarding the purple fringing, have you tried the snaartrick: In Photoshop or Elements, ask for Reduce Noise in the Filter menu, set strength to 1 or 0, and Reduce Colour Noise to max or 100%.

It seems to take out some of the purple fringing without mangling the rest of the image..

thanks Peter, that sounds like something I should try.

One thing I forgot to mention, that I hadn't picked up with the EM-1, when I put the MF lens on the body it automatically switched in MF on the SCP, a neat trick.

Wish the light would improve so it would be worth going to the quay to shoot a few birds

Once again I have to point out that there is no exif metadata in photos posted to the forum.

It is so useful for this information to be preserved and there really isn't much reason why it can't be preserved.

If anyone needs help in preserving exif data please let me know.

A couple more test shots, indoors with poor available light

IS is working well and focus acquisition is fast and accurate even in the poor light

Still no exif data (I'll stop nagging now!)

Ian, the reason there is no exif data embedded is because most of my images are from my Blog, (http://imagesfromnature.foliopic.com/ ), I am putting in what I consider to be the key info (when I remember) please let me know what you feel is missing and I will include it

(I'm loathe to start putting my images up in my blog, in the gallery here and / or in Flikr because I really don't have the time)

That flower shot is lovely and crisp.

You could do it the other way around and upload your photos here (only) - then you can post the images on your blog using the gallery's BB CODE. :)

I had a chance for a quick test shoot around Christchurch this morning, in dire conditions but I shot a few frames off in the Priory which confirmed that the IS is working pretty well (and no lock-ups so far :) )

This was shot with 1/8th sec using the Olympus 9-18 (hand-held)

Here is another, shot as I was leaving the Priory, which I liked as it showed a good range on low key tonality (I did try using hand-held HDR of the same shot but found it too grainy as a SOOC .jpg - this is processed via LR5.2 from the .orf file)

Again, the exif data is in the image Brian. No need for the link... (although Flickr's terms and conditions say you must provide a link to the picture on Flickr when posting elsewhere.)

thanks Brian, I know its there but apparently not everyone can read it, hence my new approach

Thanks - yes the exif is preserved in the latest images hosted on Flickr. :)

glad I found an answer that suited us both Ian (I'm a bit long in the tooth to be changing how I do things these days :o )

a few "Bird shots" during a bit of testing of the new body

a grab shot of a gull over-flying my garden

A raggedy old crow scared up on Hengistbury Head yesterday (little bit of CA fringe in this one)

A posing gull, also from Hengistbury Head

http://farm4.staticflickr.com/3831/10795792485_4597a7b363_o.jpg

all shot using my oly 75-300.

This combination seems to be working OK and focusing quickly using CAF, focus lock Normal and CAF release set without waiting for lock confirmation, 6fps frame rate

EXIF should be available as these are from Flikr

As its a sunny morning I thought I would shoot a couple of test frames using my recently acquired canon fd 200mm f2.8 on the new EM-1.

I've set the DOF preview button on the front of the body as the "magnify EVF view" control and am finding that that works well with this combination.

When the focus is spot on there appears to be no sign of CA but the moment focus drifts even a foot or so fringing becomes very evident

Here are a couple of focused shots, uncorrected for CA

Our resident collared dove - this is a crop of about 30% of the original

My short range focus test target (at around 50 ft) - always a good CA test as well - cropped to around 50% of the original
