  • You'll see about one stop greater DOF from m43 compared to APS-C, assuming the same field-of-view and lens aperture setting with both systems. -Dave-
  • Replied in My suggestion...
    ...is to follow Bob's recommendation and shoot RAW + JPEG, then process whichever of the two you want while saving the other for possible future use. These days I only use RAWs for printing or for ...
  • I don't find this to be an issue at all. One thing to keep in mind is that the Oly 45/1.8 focuses much closer, down to 50cm, than a (non-macro) 35mm-format 85 or 90mm can. DOF decreases along with ...
  • The Four-Thirds Oly 50–200mm works well with the E-M1, via adapter, regardless of firmware version. You might find, though, it focuses a bit quicker with the latest firmware. If you opt for this ...
  • Replied in My comparison
    I posted some stuff re. the Voigt 42.5 & Oly 45mm lenses after getting the former last August or so. This is a link to a subsection of a longer thread: http://www.dpreview.com/forums/post/52066380 ...
  • Here's the proper (full res crop from the) final version of my moon pic from a couple nights ago. D'oh! E-M1, 50–200mm at f/4, ISO 200. -Dave-
  • Just after sunset. Same camera/lens combo (Mk II version of the lens) as you. ISO 200, f/4. E-M1, 50–200mm lens at f/4, ISO 200. -Dave-
  • My m43 cameras are all capped at ISO 6400 with auto ISO enabled. If I use a manual ISO it's typically 'cuz I want a lower value than the camera's choice. With a fast lens and IBIS I have no need ...
  • If you don't already own any, there are three (that I can think of right now) kinds of non-native lenses I'd consider getting. 1) An 85mm f/1.2–1.4 for SpeedBooster use. Great for portraits and ...
  • Personally I don't want less noise. One of the things I like about m43 is that at lower ISOs it has similar texture (noise/grain) characteristics to my favorite 35mm transparency films. I know ...
  • Better compatibility with Four-Thirds lenses (via PD-AF), smaller focus points (though the E-M5 has these now via firmware update), more comfortable grip than the E-M5's, built-in intervalometer ...
  • Replied in A prime walk
    Pretty much everything I've posted online over the past 15 months has been via my iPad. I do my post-processing work in the Photogene app after import via Photos and (often) RAW conversion with ...
  • No, not at all. Maybe Voigtländer owners post more b&w 'cuz they like to experiment with tonality as well as lenses.  :-D I don't mind using a mix of Olympus, Panasonic, Voigt, etc. lenses. It's ...
  • My M8s do auto-ISO in both aperture priority and "manual." (Full-stop ISOs only.) How is it that this capability disappeared in the 240 in the first place?! -Dave-
  • The thing I love about m43 is how, via lens choice(s), it can be so many different things while remaining basically small & light. You can put together a system of fast AF "primes," or bolt on a ...
  • Sensors don't detect wavelengths. They just record photon strikes (and convert the photons into electrons). Since the goal with a camera is (usually) to emulate our eye/brain response to light, UV ...
  • Sensors can detect light both above our eye/brain threshold (UV) and below it (infrared). X-rays and microwaves aren't part of the deal, though.  :-)  On a trip back in March to Grand Canyon ...
  • I own a 12–40mm as well as a 12/17/45mm set. On my "big" m43 camera, an E-M1, the zoom gets used a lot. On the more compact GX7, though, it's all single-focal-length lenses. Are you a person who ...
  • Replied in Yuck!
    Either your hands are very shaky or you've got a defective lens. I'd exchange it for another one. -Dave-
  • Replied in Leica S Coming
    I dunno about the sensor. Leica prefers a 3:2 aspect ratio (not counting rebranded Panasonic compacts) and the Sony sensor is 4:3. They could crop down to a 44x29.3mm imaging area, which would be ...
