I would visit Cincinnati for the older library, not the new one, guess I don't have to visit Cinnci. That is amazing space, function, and ideology. Most library today are open space for people to surf the web and some might do research, but books are part of the background.

On What is equivalence and why should I care? article (1760 comments in total)
In reply to:

olypan: What is the fundamental motivation behind this article. Could it be to stem the tide of discontent with the Canikon duopoly and the realisation their end is near?

@richard bulter

the odd thing about medium format (mf) and Large format (LF) is the ISO never went too high and processor/burst rate weren't there. Those makers weren't exactly electronic guru as most of the consumer camera makers are. Maybe it is the limitation of ccd sensor, but sony new mf cmos sensor might change somethings. LF & MF weren't not meant for sport/action tracking, mostly for studio and still type photography.

T3: You don't buy a Rolex because it tells time better than other watches. The same goes for the Leica T. It's not pixel peepers and price comparison shoppers who are going to be looking at the Leica T. This is for the people who regularly fly business or first class, not for the rest of the people sitting in coach or economy class.

@fz750
let see I own(ed over the years) 1 dell, 1 lenovo, 3 vaios (1 was an ultrabook touchscreen) for laptop, 1 gateway netbook. 1 micron pc and one current pc I built and maintain by upgrading. Only the lenovo died on me as there was a power surge and the mb fried. IBM service was good to fix the lenovo speaker problem. The cheaper price items are slow but they weren't defective. My touchscreen vaio didn't boot up so I called sony. They paid for shipping and all and it was working again. Then it happened again, went to the sony store to complain and they told me to hit the reset button with a pin under the laptop. I guess sony update their mb bios and these tablet ultrabook are effected, but not my other laptop. Can't really use a mac in architecture as most of the software are pc base and we need to update parts every 1.5 years to stay competitive. Most higher end workstation card too. Maybe iOs will have touchscreen someday it is nice to have.

In reply to:

Thomas Kachadurian: The one clarification that is missing is that this does not hold with exposure.

If I expose a photo at f4-1/125-iso400 with my Canon 6D and a 50mm lens, and it is the correct exposure, then make second photo in the exact same conditions f2-1/125-iso400 with my Olympus EM-10 and a 25mm lens the second photo will be 2 f stops over exposed.

Exposure for that scene will be f4-1/125-iso400 with any lens camera combination a Sony RX100II, a Panasonic GH4, A Nikon d7000, a Canon 5D3, or a Hasselblad film camera. Crop factor does not change exposure.

I cannot tell you how many of my students come to me confused about their photos because they read about equivalency on the web and adjusted their exposure accordingly.

yes page 4.

for exposure: the iso will be the same if the shutter speed differ; if you want the shutter speed to be the same then the iso will differ. I could of said vice versa. The difference here can tribute to shooting style on a tripod or handheld. Somebody earlier below wrote that a smaller sensor are better for landscape. Maybe for a hiker hand holding, lighter gear in some cases. But some of the best landscape photography is done on a tripod base iso100 and with ND filter on longer exposure. So how you shoot differ among cameras. Some photography teachers only want their students to buy dslr, since the equivalent are very similar and they don't have to do the math or explain why things differ. A teacher should be able to explain the differences if they truly get the concept regardless on camera types.

another comparison is a mac book pro/ apple in general. Same intel processor as other, same ram, lesser graphic card this most gamer laptop, but in a nice body for a higher price. Sony tried to do this with vaio but its advertisement, appeal didn't resonate for people to spend more.

except for the sony speedlight prices, I like how sony flash head can be rotated and tilt up, in some way eliminating the need for a l bracket. Plus sony has the fill light lcd too. which higher end metz do have. These are lower models then what they offer for other brands. Wished nikon would get a rotate and tilt up flash head plus fill light update like sony speedlight.

Nikon will discontinue support soon for capture NX-2 which is a bummer. Really there are few raw editors left, there are plenty of raw converters. Adobe gets richer with the cloud, nice timing.

Artpt: What about cats...I don't think any member here suggested using cats in these dream like photos and underwater....

Yes, the cats will likely need sedation (they hate water) and judicious use of a breathing helmet...

I think the cats will definitely satisfy most opinions here....

:)

yeah he definitely missed the opportunity to tag "cat" in this photos. Much more people will google that and then see this project.

actually this scene is missing a shark with a freak-en laser attached to its head or just more fishes.

Those models are most impressive, they have to hold their breath and wait for the photographer to adjust their settings and take test shots.... And everybody else has an oxygen tank but them, I see one photo where they are getting oxygen feed.

Not sure why he is using the d90 when he usually use a d800, must didn't have an underwater case for the d800.

forpetessake: The only amazing thing about Lytro is that after all these years the investors haven't thrown the towel yet.

RAW,

I don't know if this will be successful or not. I actually like the idea and the potentials, but just not ready for prime time yet. What I am saying, they are just a bunch of entrepreneurs in the back of their mind ready to sell their concept (patents) to the highest bidder. I don't see Lytro as a camera company selling to the masses, unless somebody buys their name and use their concept in something.

pgphoto_ca: Be carefull....it's not a f2.8-f4 with this sensor (2.7x crop)....it's f5.6-f8 or more.......the crop factor need also to be apply to the aperture :)

A real 400mm f4...is much bigger ! :)

Are you guys doing the Tony Northrup's argument here:

https://www.youtube.com/watch?v=6Im4W_9blhY&list=PLBE338967F8DB7F2A

I think he (Tony) is saying you would get the look of f5.6-f8 equivalent, but the light gathering is still f2.8-4.0 per his argument.

that is not how entrepreneurship works. These guys will puff this concept as long as they can to get somebody to buy it off (like Canon, Nikon or Sony maybe facebook). Like how facebook bought Oculus Rift for way more then it is worth. MS buying skype, yahoo buying flickr, amazon buying dpreview...

I know a few people that started a startup, hoping someday somebody will buy them up. They are just making free software hoping they attract a lot of users increasing their value.

mantra: hi
i still have lightroom v4 64bit ,for it permorms better then v5
honestly i did not find new v5 feature to push me to buy v5

is really v5 more powerfull then v4?
is worth to upgrade?

by the way thanks for the video!

no it is not. It is a minor update, unlike from 3 to 4 which was bigger, better engine. The engine here is basically the same, but very few minor features like: straighten your image a little easier and spot heal is from photoshop which is a tad better then before.

the only reason I even upgraded was adobe trick of not updating camera raw on older software and just new one. Got a Sony A7, which wasn't supported in LR4. No, I am not interested in adobe dng converter for any old lightroom versions.

Karroly: Is this video supposed to teach us how to clean the GoPro sensor ?

no it is for people that wants to buy a dishwasher. If you need to know how good a dishwasher clean between two models you are interesting in, throw a gopro inside it to test.

Where are the dishwashers sell link here, give amazon some love.

W5JCK: I didn't know that Amazon owns DPR. That explains a lot. Amazon has ignored user requests for years to change some of the idiotic formatting on Kindles, just like DPR refuses to get rid of the idiotic white text on black background that makes you see stripes in front of your eyes. I'm sure this new Amazon device will sell dozens of units just like its latest sibling the AmazonTV. Bwahahahjahjahaha!!!!!!!!

I prefer white text on black background, easier on the eyes. Gamespot has the option to switch between b or w background some time ago, I kept the black. Pictures, videos look better with black background...

Amazon owning DPreview, well that has been awhile. I think this was a British site (all the old London Bridge photo references) until amazon moved them to Seattle. Notice the writers having English last name (granted the US is a melting pot) not the common ones here. Amazon got deep pocket and need some references for all the camera they sold. Did you ever noticed the dpreview link/references on amazon? I think amazon is the largest seller of digital cameras out there, nothing new here.

joydiv: Shipped my D600 to Nikon facility. Waited 7 weeks to get it back. Had NO status update during that time (except a letter after 3 weeks saying my camera had arrived). Nikon said they replaced all the stuff responsible for oil spots. Started using my camera with great expectations only to find ugly spots back in a hurry. I am so so disgusted with Nikon right now (and I have been a huge fan).

look like if you send it in again they will give a new d610. Go to the d600/610 group on flickr and that is the new report from actual owners.

Snapseed is still one of my favorite editor with it control point (nikon CNX2 style) and plenty of options. This can add to it when uploading to Instagram (more edits).

Lab D: For those who say, "AF tracking is better in even entry-level DSLRs"
by "entry-level" do you mean D4s?
http://www.youtube.com/embed/up8K_xd_iwU

Well most entry dslr have 1 to 11 af points. And 1 is crosshair type, then this sony with larger af coverage should do bettter for af c. But for lowlight I will pick the d7100, 7d, k5 over this for action with its coverage with more crosshair type af.

instamatic: Nikon sales must really be hurting so they launched this campaign. Good, but too little and too late.

I hope Nikon is not oblivious to the notion that DSLRs are slowly progressing on a way to extinction. In my opinion it's not only about rebuilding user confidence in the brand, but also about deciding where to take the company next.

Hint: The Nikon 1 system is great in hands-on practice, but poorly marketed, and unappealing to the Western consumer. Why? The Western consumer wants large numbers, i.e. large sensors, large ISO values, large etc., and at the same time he wants full manual control. Actually none of those things are needed in practice because Nikon 1 is so surprisingly smart in taking photos in auto mode, but the consumer won't know this until they use the camera, and to use it they need to buy it - because now cameras are mostly bought online not in a brick and mortar store when they can be tried first. Nikon 1 is expensive - the consumer concludes to skip it.

""DSLRs are slowly progressing on a way to extinction""

More like dslr sale are plateau-ing. MILC are barely stealing any market away. I see young photographers and they are still are buying dslr handover. Go to any convention and the young ones are carry dslr. MILC are usually, to be frank are the older mature crowd. I have both, like the portability of a milc, but prefer the performance and overall system of dslr. Amazon sales also show milc is still quite small, the extinct P&S market is still the best seller.
