At the risk of being hard to please I wonder if version 2.1 will give us ISO 50 for those of us who can remember Velvia 50 and K64!
you are 'gaining' the ability to shoot in higher light levels overall as well as the use of longer shutter speeds for things like running water....at the minimum cost to IQ; you aren't magically getting a new 100 base sensor or improvements over the IQ available from the existing base 200.

Re: New Firmware 2.0

Yes, K25 was impressive stuff, although while it was still available K64 was not far behind. Sadly in its last years Kodachrome tended to suffer from poor quality processing . Modern digital cameras with ND filters can easily beat both though

Re: New Firmware 2.0

I wonder why Oly are calling the new ISO "LOW" rather than ISO 100?

On my other brand of camera ISOs called low and high are named like this as a warning that some aspect of image quality is being traded for the extra ISO.

Does anybody have an E-M1 manual that describes the LOW ISO? Are there any notes about image quality e.g. highlight data at the low ISO?

Re: New Firmware 2.0

Explain how to fit NDs to the 7-14, 8mm and some of my legacy glass with no filter threads.

there appears to be general agreement that the greatest DR is available at 200, and has been since the E30 came out.

there is general agreement that using 100 will reduce noise over 200 - however whilst this was definitely a factor even in general shooting with the 30 is has become increasingly less of one with the recent models; with both the Sony sensor in the EM-5 and the Panasonic one in the EM-1 many argue that it's simply not a factor in properly exposed images (and hence they shoot at, and recommend, 200 regardless - McGillicuddy is an example).

some will point to tests that illustrate a higher degree of detail in shots at 100 (based on RAW file size) but others will point out that you only have to have a tiny degree of increased exposure on a file to increase the file size dramatatically and is 100 really 100 etc etc

personally I've shot 200 since the E30 but have always recomended that people do what gives them their best results - you can't seperate the issue from exposure preferenes and image rendering workflow when considering any practical differences.

as to Olympus - in the manual they state that 200 gives the best balance between noise and DR; in discussion that will point out that 200 is the native sensor sensitivity.

Nope. I want someone to tell me what to do. Then I'll go and do it. I'll have none of this, so called "thinking" malarky.

What I take away from this is:
  • Need to cope with a contrasty scene? Use 200.
  • Need the best quality in a not-extreme DR situation. Use 100.
  • Need simplicity? In a hurry? Use 200.

Is this right?

some say yes and some say no (with an E-M1)

I say no, but I can't see how my view is relevant

logically it can't be right with the EM-5 because if it were it follows that Olympus launched it without the best 'quality' being available

Re: New Firmware 2.0

I've done some testing on both my E-P5 and E-M5 post upgrade and this is my experience:

- ISO low/100 gives lower shadow noise, but reduced DR. It's easier to clip highlights.

- If you shoot raw, you can get exactly the same results at ISO 200 by overexposing by 1 stop and pulling it back in post-processing.

Net, net - describing it as "low" is a reflection of what's happening. It's a post-processing trick. Personally, I'd have been happier if Oly had spent the time on the firmware upgrade adding the ability to assign Mysets to the mode dial. Then, instead of pressing menu,right, down, right, down * n, right, enter, up, enter - all I'd need do is move the mode dial!

Re: New Firmware 2.0

Hi I recently updated to 2, yesterday i went out and gave it a try out all shot at low iso. Well it was bright high sun and contrasty I went into our lovely forest area, I am very pleased with the results, wish I had done comparison shots with iso 200, as I think they have done so trickery some where as the images have good dynamic range, but I swear the images are sharper than they was before, I am well chuffed with it, well done Olympus for this.

Dave

I'm glad I'm not the only one with this impression, for me its most noticeable in the studio shooting female portraits (so far)

Re: New Firmware 2.0

Hi Here is an images taken in the Forest of Dean the other day, when it was bright and sunny and very contrasty, iso 100(low) no sharpening just a slight clarity structure only from raw using the kit 12mm 50mm lens.

Dave
ps sorry this is a link as it is a bit biger in size so you can have a better idea of the crisp and sharper the image appears to be.

Re: New Firmware 2.0

This is an interesting article:

http://www.rawdigger.com/howtouse/ex...w-or-for-jpegs

Conclusion is that the OM10 (and probably all current u43 cameras) underexpose by at least 0.8 EV and maybe up to 3 EV depending on conditions. Given that, it would seem there is quite a bit of scope for not blowing highlights.
