  • Reminds me of the time I built a comparator box allowing for different combinations of hifi loudspeakers and multi-speaker derivations from a stereo signal to be compared. I invited several ...
  • In the last ten years I've used a lot more memory cards than cameras. I've had one memory card fail and four cameras fail. I've also had three lenses fail and two flashguns fail. I'm therefore ...
  • My first DSLR had a CCD sensor. When I broke it and replaced it with a later CMOS sensor model I was aware of the issues you mention above, and also the caveat that even then it was rather ...
  • An updated LAEA4 adapter will be technically less challenging when E-mount AF has become able to better the performance of A-mount, i.e. the SLT is no longer necessary.
  • Statistically uneducated.
  • Well, I don't have as many kids, but I am a few years older :-) Me too. Excellent "swiss army knife" of a lens for quick opportunistic shots. This is weird. I now have a smartphone which takes ...
  • If you've just spent a small fortune on "the best lens", obviously "the best" because it was the most expensive, and if it was the most expensive then it will have a very wide aperture, then ...
  • You can also use focus peaking to check focus more precisely without using magnify.
  • That kind of thing on my my cameras has always turned out to be on the sensor rather than the lens.
  • This could have been the result of lens distortion correction being set in the one camera, and not in the other, or using a lens (or focal length on a zoom) on the A99 which needed more geometry ...
  • That's the wrong question. The kind of lens you should buy is the best you can afford. Sometimes that will turn out to be a new lens. Sometimes an old lens.
  • Replied in Does......
    I increase the number of my jpegs which are good enough (I shoot RAW + JPEG just in case they're not) by turning down the contrast, sharpness, and colour saturation. That increases the latitude of ...
  • A good EVF will have an auto brightness mode which will adapt to the light levels, becoming bright in sunlight and dim in the dark. It will also be switchable to manually controllable brightness. ...
  • The reason why there are (for human eyes) three primary colours is because our eyes sense colour via three colour pigments. If we used more (as some animals do) then we would need more primary ...
  • And 7 and 9 bladed apertures. But it's not just the shape of the aperture, it's also the nature of the aperture, e.g. the apodisation filter "apertures", which could be said to have no shape ...
  • Similiciionsar but not quite so bad an experience. I rotate 5 batteries in sequence through my camera. Two of them are my original A350 batteries, still ok, doing more than 200 shots per charge. ...
  • Lenses which focus at the same speed in good light may focus at different speeds in low light simply because the lens characteristics are different, with one lens in poor light forming an image ...
  • You'd have to find out what paper and inks your lab was using, and then check expert reviews of those, to answer that question. It's VERY variable. My wife used to stick family photos on a section ...
  • Is there a mechanical shutter involved? It looks like shutter shake.
  • Another possibility for removing the moire would be to focus just enough away from the troublesome fabric so that the slight focus blur removed the moire. I encountered a similar situation recently ...
