About me:

Found an interest in photography back when I bought a cellphone that had a camera. 640x480 "VGA" images weren't glorious, but they were a start. Later won a compact camera in a raffle, and then realizing I wanted more, eventually moved on to DSLRs. I've been trying and enjoying most forms of photography since then.

  • That is a very nice photo of a fox. I use an E-M1 mark II, which as others have said, has superior PDAF over the mark I by the inclusion of cross-type arrays, similar to what we knew and loved from ...
  • I have a few PRO lenses (but no non-PRO), and they all have a small, raised, red circle at the back of the lens barrel for alignment.  I recall all of my Olympus 4/3 lenses having the same ...
  • You say you're a beginner, so I hope you won't mind if I explain a few basics before getting into what you're likely observing. When it comes to exposing a photo, there are three settings that ...
  • The 12-100mm f/4 was my first µ4/3 lens.  I made the decision to come over to µ4/3 from 4/3 after a 4-5 year hiatus from photography, and really didn't expect much.  We 4/3 users were hostile to ...
  • I don't own the 12-40mm f/2.8, but I do have the 40-150mm f/2.8 (and the old 4/3 35-100mm f/2.0).  I can't contribute to the main topic, but I did want to speak to the point of subject isolation ...
  • I suspect this is not a problem with the lens, and more something with ultra-wides, as noted previously.  I don't use your camera model, but my E-M1 Mk2 has a digital level that I use almost all ...
  • These lists sound pretty good.  I've been pretty pleased with my E-M1 Mk2, and honestly don't imagine that I'll be upgrading with the next generation because the changes will likely be ...
  • I don't recall having issues using my E-3 in the winter with gloves on.  My E-M1 MkII is a bit tricky by comparison... doable, but I struggle a bit. It's not just about whether you can use gloves ...
  • Unless you're pushing each of your lenses to their extremes, I'd make the change. It's not just for the convenience of it.  The 12-100mm's optical quality is stellar. I am consistently shocked by ...
  • I came from 4/3. There was no grip for my old E-410 or E-520, but I bought a grip for my E-3, and it never came off once I installed it. (Which was also partly because it was a bit finicky for ...
  • Aside from the silent operation (both on the camera's end, and for µ4/3 lenses, the aperture mechanism is near-silent as well), the E-M1 mk2 has a feature you might be interested in: Pro Capture. ...
  • I came to µ4/3 from 4/3, too.  That was about two years ago; I was strongly considering a move to Nikon.  But I knew (and was OK with) Olympus' menu system, and more importantly, I had a ton of ...
  • Shallow DoF is a monetarily expensive but artistically cheap way to draw focus and not deal with proper positioning or dealing with bad backgrounds, but it can also be used to invoke a dream-like ...
  • Thanks for this interesting comparison, along with the examples.  The bokeh looks pretty similar to me, and there were some samples where it seemed like the Sigma had the sharper, better image... ...
  • Replied in Onion chopper
    But can it chop onions without introducing a lot of noise, and does the noise level increase in poor light?  If not, you might want to spend a little more and get a larger onion chopper. :-P
  • Replied in More telephoto!
    Not sure why Olympus always stopped at 300mm, but we're missing quite a bit of capabilities here. I own 4/3 versions of the Sigma "Bugma" (150mm f/2.8 macro) and Sigma "Bigma" (50-500mm f/4-6.3)... ...
  • If you go by Olympus' marketing with the dual-IS, you're actually gaining about 1.5 stops with what the image synchronization can do... so technically, you're losing a stop of light, but gaining ...
  • Interesting, I suppose I should have figured that a product like that would exist!  I'll pass on it - I like my photos to be as sharp as possible, but it's nice to know that such a thing exists.
  • If there's an appeal to it, it's probably because it hides flaws present in reality.  With fewer fine details present, the viewer gets to fill in some of the details, themselves.  I don't have ...
  • I've seen a few Pens, usually from Asian (I assume Japanese) tourists.  I've seen a few Panasonics, as well - usually the larger bodies. My most interesting story is from back when I was living in ...
