    Your favorite fast wide lens?

    Takes filters, lighter, IQ just as good. The filter point is a big deal in my view - but I do miss that extra mm at the wide end!

    What is the best exposure for your Olympus? (ETTR and other techniques)

    I'd be very surprised if gradation and saturation settings affected raw files.

    Your favorite fast wide lens?

    PL 8-18 is, IMHO, the best UWA zoom in the system.

    The need to move forward with M43

    I've had two 12-40s. Both were excellent, but the one I have now is just spectacular. I can't tell the difference anywhere in the frame between f2.8 and f8. It's sharp corner to corner at all focal lengths with fantastic contrast. A marvel of optical engineering. Unless you need the larger...

    The Olympus M. Zuiko 17mm f/1.8 vs Panasonic 25mm f/1.7

    I don't fully agree with this. I've had two copies of the 17/1.8 and whilst the first was a bit soft, the second is superb. I've compared it back-to-back with the PL 15/1.7 and there's nothing between them.

    I just received my E-M5 Mk III and...

    I played with the E-M5iii on a recent pilgrimage to B&H. My initial reactions were the same. It's the first OMD body I've handled (including the E-M10 range) where I was disappointed with the feel. Felt cheap and unworthy of its price tag. I'm sure it'll deliver great results though, and I...

    Olympus OM-D E-M1 Mark III Released

    So, third day in after the announcement, and we're only just hitting page 6 of this thread. I detect that there's not a lot of excitement or emotion.

    Olympus OM-D E-M1 Mark III Released

    I agree with all that. I love my Oly gear, and I'm personally happy with the IQ it gives - but it does seem that it's not taken seriously by "serious" photographers. I think it's classic middle market malaise - when the squeeze comes, some go down-market (cheap, good-enough), and others go...

    Olympus OM-D E-M1 Mark III Released

    They're talking of the "Tracking" mode whereby a little square box appears on what you initially focus on and then it sticks on that object. It's almost completely useless. Has been since the first Oly m43 camera I saw in 2012 and it's no better today. Keeping the subject in the focus area...

    Olympus OM-D E-M1 Mark III Released

    I agree with much of this article, but I do think he's down-playing the IQ from m43 cameras too much - for example: I don't agree with that at all. Printing big from m43 is not an issue. In fact, the print medium is way more forgiving than pixel peeking on large monitors. And who seriously...

    Dixons store at Heathrow Airport no longer selling Olympus

    As per title. Store there has sold Oly gear for a long time. All gone now. Panasonic still holding on, but almost no lenses - just three bodies. Fuji, Canon, Nikon, Sony all present in force. There's even a Leica cabinet! Not sure if there's any strategic message to pull from this -...

    Olympus OM-D E-M1 Mark III Released

    I guess it's all about expectation management. For my taste this represents a lukewarm makeover, nothing else. Look to the EM1 to EM1.2, or XT2 to XT3 or A7ii to A7iii, or G7 to G9 - in all cases the evolution was much more significant - new sensors, new EVFs, ... So, yeah, I'm disappointed...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    No Olympus shutter up to the one on the E-M5ii was immune to shutter shock. Some cameras were worse than others, and the effect would be dependent to some degree on the lens fitted (for mass damping reasons, not optical). However, the E-PL5, E-PM2, and EP5 were all pretty bad. The underlying...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    This is frustrating.... I DID NOT "mix exposure with image brightness (ISO)". Why are you saying this???? Yes, I agree with this (phew!).

    What is the best exposure for your Olympus? (ETTR and other techniques)

    Yes, I'd forgotten that DxO use measured ISO and not manufacturer-declared ISO on their graphs, so the left-most point on the plot I referenced is actually ISO 200 on the dial. However, Bill Claff's site does go down to extended low (which is actually ISO 80 on the Pen-F)...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    I'm not going to dispute that. Real-world cameras and sensors will add complexity and subtlety. But in most normal photography these will be second-order problems compared to just getting more light on the sensor and that is what ETTR, for most people, should mean. Using ETTR at higher ISOs...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    I'll try to be more explicit... Actually, I didn't prove that at all. I showed that over-exposing at ISOs above base and pulling back in post is no different to using a lower ISO and exposing normally. I don't think I showed that at all. Image brightness is a function of exposure, ISO...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    Sorry, but I just don't understand your point here at all. I accept that lower light would exacerbate the noise issues, but I don't think it invalidates my point.

    What is the best exposure for your Olympus? (ETTR and other techniques)

    Incidentally, some people say that using the extended low ISOs on Olympus cameras (64 and 100) is the same as over-exposing at ISO 200 and pulling back the raw file in post (as I've done here). I think in fact that this is not 100% accurate. I haven't been able to find definitive information...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    OK, so let's try some controlled experiments. Here's the rather messy scene in my home office. It's not a very high contrast scene, so definitely a candidate for ETTR. The above shot, and all the following were shot on a Pen-F in raw with the Oly 17mm f1.8 @ f1.8; then processed in...

    New Olympus Camera Mid February

    Well, all I know is this ... when I peer into the EVF of a G9, XT3, A7iii, Z6 etc, I go "wow, that's bigger and more detailed than my EM1.2". When I peer into the EVF of an EM1X, I go "meh, a bit more magnification than my EM1.2, but much the same". When I peer into the EVF of an EM5.3, I go...

    New Olympus Camera Mid February

    Crikey, it's worse than I thought. The panel in the EM5.3 looks SMALLER than the one in the EM1.2. How do they expect to compete with the G9, XT3, A7III, Z6 etc with such a low res EVF?

    Is there an "influencer" who hasn't been "fuji-x100V-ified"?

    I tried the original Fuji X100 and found it to be a very frustrating camera. Didn't get on with it at all. The lens was not the greatest, the aperture limitations of the combined iris/leaf shutter were annoying, the viewfinder was clumsy, there was no tilt screen (essential to me now), overall...

    Is there an "influencer" who hasn't been "fuji-x100V-ified"?

    Answering my own question here ! :) Actually, my Pen-F plus 17mm f1.8 is pretty close to this. And if I want I can remove the lens to clean the sensor and put something different on it! Dumb idea really on my part ;) But of course the Pen-F is discontinued :(.

    Is there an "influencer" who hasn't been "fuji-x100V-ified"?

    On the wider front - is there a market for an FF version of the Fuji X100? Something that doesn't cost Leica Q or RX1 money. Something like the Olympus Trip 35. I'd love to see a modern version of the Trip. If Oly (or Panasonic) could pull it off at the same price as the Fuji, or perhaps a...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    The really important point to grasp, which is easy to overlook, is that the ISO dial does not change the sensor's sensitivity. The ISO dial is effectively an amplification dial. At base ISO, the amplification is at its lowest. Anything above base ISO is adding amplification. You need to...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    It probably won't. That's my basic argument with Siegfried's article. Over-exposing by one-stop ("+1" according to the camera's meter) at ISO 1600 will be very little different to a "correct" exposure ("0" according to the camera's meter) at ISO 800. The reason is that in both cases, the...
  40. pdk42

    What is the best exposure for your Olympus? (ETTR and other techniques)

    Precisely. I think Siegfried has really over-complicated it. The rules really are very simple: - Use the lowest ISO possible. - Give the sensor as much light as possible, whatever the ISO. Use the histogram or blinkies to help - If at base ISO, exposing to the right and then correcting in...

    What potential new feature would make you buy the E-M1iii?

    Dave - except for improved optics (in particular higher magnification), the EVFs are the same on both the EM1.X and EM1.2.

    What is the best exposure for your Olympus? (ETTR and other techniques)

    Maybe we're saying the same thing in different ways :) I think we both agree that: a) The best way to get the cleanest, least noisy image is to make sure we fill the sensor's wells to their maximum b) The only ISO at which this can happen (without the generated file being clipped) is to do it...
  44. pdk42

    What is the best exposure for your Olympus? (ETTR and other techniques)

    No, that's not how it works. Each "sensel" (pixel point) is an electron well that accumulates charge. Electrons are released and accumulated as photons enter the sensel. Essentially, a sensel is a device that turns photons into electric charge. The number of photons to fill the well is a...
  45. pdk42

    What is the best exposure for your Olympus? (ETTR and other techniques)

    But you'll only fill the wells at base ISO. My definition is that it's a technique to use all the available exposure levels on the sensor. You'll only do this at base ISO.
  46. pdk42

    What is the best exposure for your Olympus? (ETTR and other techniques)

    Agreed. Agreed Yes, but "enough light" = fill the well. You won't be filling the wells at ISOs above base, because ISO>base ISO = gain after the sensor. But overexposure at more than base ISO is not the sensor being overexposed, it's the final value after electronic and digital amplification...
  47. pdk42

    What is the best exposure for your Olympus? (ETTR and other techniques)

    For sure increasing exposure will help, but it'll only fill the wells if you do it at base ISO. If you've selected a higher ISO then the wells will be partially filled and then amplified to get the brightness right. That's what going above base ISO does. All you're doing by ETTR at a higher...
  48. pdk42

    What is the best exposure for your Olympus? (ETTR and other techniques)

    ETTR is a technique to ensure you fill the photon wells on the pixel sites to the maximum. If you're not at base ISO, then you're using gain on the electronics (or ADC) to compensate for unfilled wells. That's what's happening when you increase ISO. Remember that unlike film, you're not...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    I've pondered that a lot of times. I assume that the rendering of the raw data into something you can see is performed in LSI circuitry in the camera. That being the case, it's possible that getting at the raw values to produce a raw histogram is not a trivial matter. However, that's all...

    What is the best exposure for your Olympus? (ETTR and other techniques)

    But if you want the best image quality (incl best noise handling), then you should be shooting raw, and in raw the contrast and sharpness setting have no meaning.
