Robert Holloway: I find DP Review's comments section increasingly depressing and useless. Endless people with no interest in a product pouring venom on every post. I won't be buying these lenses, but what fascinates me is to check the gear owned section of these critics.

People criticize the lack of lenses for Sony and the pick faults with every lens released.

I'm not sure if it's fear based (they are killing my brand) or simple ignorance. Today, none of them have used these lenses of seen the results.

Maybe that's what DP Review has become - a forum for people to desperately defend their positions by offering nothing more than scorn and venom on every new initiative in a dying industry (that's right, phones are the enemy) . Very sad

Rob

It's always been like that hasn't it? I can't say I've noticed it getting worse. Comments sections are always depressing displays of ignorance and bile. At least by some.

Whoah! 1,5 k price difference for a chip with some shading data! That's pricing that gives away too much info about their margins...

On article Sony a9 Full Review: Mirrorless Redefined (2724 comments in total)
In reply to:

pkcpga: Hi Carey, thanks for the update on the a9, just wondering have you experienced any overcorrecting of rolling shutter with the in camera software correcting. I've read that with the golf shoots in particular, golf clubs have a bend in the shaft when swinging yet the autocorrecting software on the a9 makes the golf club perfectly straight instead of keeping its flex? Just curious if you've tried out the a9 for rolling shutter issues or over correcting issue yet? Thanks, it's a tempting and interesting camera.

There's no overcorrection of rolling shutter because there is no correction of it. Instead, it's just hugely reduced thanks to the higher sensor read speed. What you might have seen is tiny traces if it which haven't been completely eliminated

On article Samyang Lens Station USB dock spotted in the wild (26 comments in total)
In reply to:

lambert4: I guess its a nice match to the only 2 AF lens available for E mount. Maybe they will expand to other systems?

yes it will be interesting; but so far the AF lenses have been worse than their MF equivalents and not very exciting at all. Nothing like their 2/135 which is far and away the best Samyang (actually the new 1.2/85 and 2.4/14 premium manual focus lenses might be great too, I haven't tried them). But I don't hold out huge hopes for this 35. Hope I"m wrong.

rfsIII: How do we know this isn't just a re-housed Canon 70-200 f/4 IS with a motor on the bottom?

It surely is; or else it's a new design which is about to offered as MkIII stills lens for much less.

OlyPent: T2 means f/1.4-f/1.7, likely FAST!

These are based on two f1.8 stills lenses..

Ran Plett: wow 14mm T2! We definitely need to know costs. I can see a lot of stills guys and girls into this lens.

Its the existing, though newish, 14mm f1.8 stills lens in new garb

Some people have died on train tracks. Far more have died on driveways of houses. Should we be outraged at driveway photos? Or pictures of people crossing the road? (a lot of people die that way). Sure it's illegal in some places, so don't do it. Sure if your local trains are super quiet (ours aren't, they are diesel behemoths) be careful. Sure it's probably not a good idea. But outrage? There's too much outrage around.

Internet Enzyme: Arent those t-stops a little slow?

Thanks all; I was mistaken. Interesting. If the are MF maybe they are based on S lenses?

Um, medium format? Aren't they Super35, which is basically APSC????

I loved my LX3 and I really wish other makers would use the slight,tbovesize sensor so as to give more aspect ratios with less loss of resolution

dbm305: Leather! Zeiss advises never to keep lenses in leather pouches, for fungus related reasons...

There are some affordable decent chinese cabinets on eBay from about 250 for 25l to $800 for 120l. Tip: don't believe the hygrometer reading. They seem to be consistent but consistently off by up to twenty percent. Get a decent hygrometer and adjust the cabinet thermostat to whatever gives your desired humidity (in my case 45%) even if the cabinet claims that's some scary number like 15 or 70...

I'm also here in Sydney, and all my gear is in dehumidifying cabinets after I lost thousands of bucks of OM gear to lens fungus some years ago!

A sensible and courageous piece.
I think that the prevailing wisdom about the amazing gradation, tonality etc of MF is a hangover from film days, when the underlying sensor film) was pretty gritty. It made an *huge* difference to expose a big chuck of film and then enlarge it much less for the same print size.
But now that's so much less true. Yes if the MF lenses were faster, the sensors at the same tech level as smaller ones, the pixel levels higher, then there could be slight advantages at the cost of size weight money and flexibility/system depth. But that's not true yet.
And even if there were that advantage, under what conditions would the advantage be visible in a final image? With FF, whose advantage in resolution and DR against APSC is big , only occasionally is that advantage visible in a print or other consumed image, though the thinner DOF available often is. I can only think hat the situations in which the advantages of 50MP MF will be visible will be rarer still.

esorensen: Never trust an article with portraits shot with wide angle lenses.

Never trust art driven by stereotyped conceptions of what focal lengths are appropriate to what subject.

On article Throwback Thursday: Our first cameras (392 comments in total)

First camera was a Diana like plastic 6x6 when I was ....6. The prints were contact printed.
Then never had another camera until my grad school days, when after much research got an OM 40. I recall I liked that it had ESP metering (which was just a crude method of trying to figure out if the subject is backlit and compensating accordingly..)

In reply to:

HeyItsJoel: Ugh. Sony colors are so awful.

You should use things like colour checker ideally in the light that you are shooting in: you could have profiles for daylight at midday, your own studio lights etc.

The resulting profiles will be likely more colormetrically accurate than the camera profiles, which do two things - calibrate AND adjust to taste. And the taste of each camera co is different. I prefer to keep those things separate. Start with a fairly accurate profile, and have LR settings that vary colour to my taste for different purposes.
