  • Howaboutraw: Do you even know what tstop is? Two different lenses rarely have identical Tstops. So, one lens is letting in more light than the other one. I have cheap primes with fast tstops that...

  • What you are claiming makes no sense. Two different lenses with identical t-stops should produce identical results at the same exposure settings. Prove me wrong.

  • And you are accounting for the differences in tstop? Tstop is absolute!

  • The "astounding" difference is merely the difference in tstops. A lens does not increase noise on any way. If they are both transmitting the same amount of light, shot noise will be identical.

  • Commented on Hands-on with the Pentax K-3 II article

    Z-axis tracking is weak from my own testing. I don't think its predictive enough coupled with lenses that can be slow to focus. Ricoh knows full well that lens focusing speed is something they need...

  • Commented on Hands-on with the Pentax K-3 II article

    @jonathan lee: what makes you think they aren't secretly working on a mirrorless solution? These things don't happen overnight. Clearly they are focusing on the FF and 645 right now. I imagine some...

    I have one. It is all you need. Unless you need reach at least lol.

    Thank you for the coverage dpreview!

  • No sirui?? A shame. Their heads are truly superb and won't break the bank. 6 year warranty too.

  • Whoops. Didn't realize these are auto leveling as well. I rescind my previous comment. Wish you could delete things here.

  • Commented on Sony Alpha a7 II Review preview

    I shoot with IBIS on all the time on a tripod on a k-3 with a smaller pixel pitch than an a7. It doesn't reduce resolution. At least on longer exposures. I've actually used to to help compensate...

  • Commented on Sony Alpha a7 II Review preview

    I shoot with IBIS on all the time on a tripod on a k-3 with a smaller pixel pitch than an a7. It doesn't reduce sharpness on a stable tripod. At least on longer exposures. I've actually used to to...

  • Commented on Fujifilm X100T Review preview

    The best camera is always the one that is in your hand.

  • Its possible they might still reserve the red rings for limiteds. Their limited line was completely revamped with red rings, so to go back would be kind of silly at this point. The 55-300 has a red...

  • That's funny because it is the same color they have always used long before sony started producing weather sealed lenses.

  • @vignes: This camera is going to be of interest to landscape photographers I would imagine primarily. Its hard to deny the power the sony sensors have in their ability to push shadows with very...

  • If you are only getting 12mp of detail from f11 on full frame its time to finally upgrade that quantaray. My 24mp aps-c K-3 shows significantly more resolving power at F11 than my 16mp K-5 IIs...

  • More DR = better images. Some people seem to forget that. I guess they are just used to using ancient sensor technology. Bracket much? ;)

  • Commented on Nikon D750 Review preview

    That's funny because I find no joy really in using Canon gear. I just never really liked their gestalt. The Pentax K-3 and K-5 IIs though just fit like a glove. The have great ergonomics that are a...
