Default Fn Little Exercise with the 75-300 M. Zuiko..

Saturday morning when I arrived back home from breakfast I noticed some guys working on a power line. I have no idea how far away this pole is from my front balcony, but far enough away to be this small captured at the 75mm end of the 75-300mm M. Zuiko..



Shooting raw+jpeg I captured the next picture with the 2x digital teleconverter turned on. Here's the raw file process at its' native 300mm focal length..



Next thing I did was to take the raw file and cropped it in somewhere between the 300mm image and the 2x digital TC jpeg..



Last image below, here is the jpeg from the camera with the 2x digital TC enabled. I did straighten it a little. Pretty darn good. The difference between the image below and what I did above was, the image I cropped above I did not "rez up". It's a straight crop with no interpolation done to bring the file resolution back up. The in-camera JPEG is both cropped and then re-sized back up in camera to the original file resolution.

Neat. That job sure wouldn't be for me that high up.

....this is another time you've shown us the camera set to 2-x and I am impressed with the results, enough that I am going to try it just to become familiar so that when I get the new camera (be it an EM-5 or the NEW announcement) I will know about this first-hand.

This is very impressive...... I am finding it more and more difficult to hold steady at the longer focal lengths AND bugs too.

Yep, I am going to try it. Is it just a matter of turning 2x on?

That's it alright. There's a guy over at DPReview who lives down in Austin and has used the 2x TC with the E-M5 and 75-300 to shoot some very nice-looking floral closeups and long-distance captures. I do not know how many "real" stops of good the 5-way stabilization actually delivers, but it certainly helps me a lot, and I have my camera set up to where the finder stabilization kicks in on the half press of the release, and when that happens it's amazing how completely still the view goes at 300mm, both with and without the 2x digital TC turned on. Certainly makes framing long-distance subjects very easy compared to the screen jumping all over the place at such high magnification like it does without stabilization.

The 2x feature can be turned on either via the menu system or you can configure a button to turn it on and off at will with one press.

...gonna give it a button and try it, thanks

1-last question, so I don't have to look for the answer, .... must one use 'P' normal processing with 2X on or does it work with 'other' exposure methods?

You can use it in any exposure mode, program, manual or anything in-between. If you shoot raw only you'll see the effect in the finder when you review the shot but "only" wind up with a raw file with no cropping done. You have to be shooting jpeg or raw+jpeg to get a file with the results from the digital TC.

I THINK I also had auto gradation enabled. You can see the jpeg is a little brighter than the image where I cropped the same raw file. The E-M5 is the first Olympus camera I have used that auto gradation is not necessarily a bad thing if the subject calls for it.

G'day Greg

All good stuff there mate -
What I'm also seeing is that the in-camera 2x dTC & JPG imagery is remarkably good ~ does one need raw for ongoing cropping / enlargements I wonder?

Regards, Phil

It really is quite excellent. As long as you've for the time to get the settings right for the light, I could definitely see one shooting raw+jpeg and only really needing the raw file for the trickiest of lighting.
