  • Yep. Probably iPhone with an RX100 sensor and lens. If we're lucky, there would have been one spin dial for adjusting whatever setting you picked from the touch screen, but otherwise it would be ...
  • We have an Oly 40-150 f/4-5.6 and a Panny 14-140 II. The Oly almost never leaves the house, the Panny is always paired with a 20/1.7 as my fiancee's go-to kit. One lens that's versatile in focal ...
  • Strategically, I think Apple was hoping:
    - Demand for cut rate Air 1s would eat up the supply of parts
    - Build cost for the Air 2 would drop enough by this point that they could've just slashed...

  • I haven't seen the speaker grilles yet (which are different between the Air 1 and Air 2), but I'd bet that at the very least they're still using the same presses as from the Air 1, if not simply...

  • So it's an iPad Air 1 with a processor that's comparable (but probably much cheaper) to the one in the iPad Air 2. I don't begrudge the processor choice at an entry level price point, but why go...

  • I'm not sure why you wouldn't just test in a dark room, with the cameras on a tripod, pointed at something that's lit, with detail - ie, a book. You expose for the book (or under expose by one ...
  • Check your shadow test against a few different ISOs. My understanding is that Canon sensors up to the 80D have relatively high read noise, thus making them poor for pushing shadows, especially at ...
  • Could you explain this 'variable afocal converter?' I thought that for a 200mm lens to be f/2.8, the aperture by definition had to be 71mm.
  • I think I need to correct you there. F/2.8 is a focal length to aperture diameter ratio. F/2.8 at 28mm is a 10mm aperture diameter (28/2.8 = 10), at 50mm is an 18mm aperture diameter, at 135mm ...
  • When the OP refers to aperture, he's referring to the actual aperture in millimeters, not the aperture ratio (the f/number). A 70-200mm f/2.8 lens has an aperture of 200/2.8 = 71mm when it's at ...
  • I know there's the urge to help, but frankly, based on your questions, I'm pretty sure you'll soon be in way over your head. When's the wedding? If it's in a few months, you still have time to pick ...
  • There's a 4/3 35-100 f/2, not m4/3. It can be used on m4/3 with an Olympus MMF3 adapter and maintain the weatherproof and autofocus of your E-M1 ii. It is considered one of the best lenses ever ...
  • With an E-M1 I, you could consider a 4/3 35-100 f/2 - both B&H and Adorama have used examples, last I checked. Too heavy for me to want to carry around (3.6 lbs before 4/3 to m4/3 adapter), but if ...
  • No, one does not buy a fast zoom solely to shoot exclusively at the maximum aperture. The fastest zooms in most ranges tend to also be the sharpest, highest contrast, and with some care taken with ...
  • I'm not in the industry, nor am I an optical engineer - I may have read the same thing you read, or something similar from the same sources. As a concept though, it's not too far of a leap - ...
  • So we're talking about the Olympus 14-35 f/2 and 35-100 f/2 Regardless of the image they project, they're still f/2 lenses, meaning that the maximum aperture diameter at 14mm is 7mm, and 17.5mm at ...
  • The FZ1000 has a sensor that's about 5x (more than 2 stops) larger than the one in the FZ200. In terms of stops, the FZ1000's 1" sensor is closer in size to an APS-C sensor (1 2/3 stops smaller) ...
  • Replied in Best M43 lens?
    Zoom: 12-40 for its sharpness, close focus, and usefulness of focal length. Prime: 25/1.4 for its sharpness (stopped down a little), good background separation for its focal length, and the ever so ...
  • Just in Iceland a few weeks ago, and plan to go back in summer - it's apparently very different there depending on the seasons. We went for the aurora borealis, which is strongest in winter, but ...
  • I dunno, I can't say I consider that foreground all that sharp - though it's obviously hard to judge off of a downsized screenshot from a youtube video. I've done scenarios similar to that video, ...
