mcam: I'd suggest to always state that while these 2x or 1.5x equivalence affect DOF, they don't affect exposure. For example, on the first page after "As such, you can say that a 50mm f/2 for Micro Four Thirds is equivalent to a 100mm f/4 Full Frame lens in terms of both field-of-view and depth-of-field." you can add "However, in terms of exposure, f/2 is always f/2."
I've seen many new DSLR users got confused when they were told about aperture equivalence. After reading the first page of your article, I have to say that it is likely to create the same confusion.
...However, in terms of exposure, f/2 is always f/2...
Exactly; the main purpose of the aperture is to adjust incoming light for proper exposure and in that context F2 is F2. However, to many the aperture is (misunderstood as) a measure of the ability of the lens to produce out-of-focus blur - and for bokeh, aperture equivalence (the multiplication by crop factor) is the way to compare (even though distance and optical design are essential)...
Brilliant article, so well written and with good examples and comparisons. It should go straight into the DPReview Top 10 for articles posted - @Richard, why not have such a list of your most popular work?
This article should end of all these endless discussions on "equivalence" in forums and elsewhere - and of course it doesn't! And the hundreds and hundreds of comments are equally entertaining and interesting to read.
Thanks Richard, and everybody enriching this article with comments...
...but is it meant to be turned on? ;-)
h2k: I think the combination of fast-motion and tilt-shift effect makes it.
As so often in documentaries, i liked the imagery and didn't like the music. It feels a tad funny to call a movie "City of Samba" and then use this kind of score.
For me the stronger effects in the Singapore film were tiring after a very short while.
...as for the soundtrack, you can find more background story by the composer, here:
Awesome - both the filming and the carnival itself! Stop-motion and tilt-shift used so cleverly, that even though I know what is going on here, I totally disconnect from my left brain and is completely overwhelmed by the stunning visuals...
But as mentioned below, this mostly goes for the Rio film, with a better balance of the effects.
AbrasiveReducer: The only bad thing about this is that when companies start with the custom color, limited edition, laser-cut box, certificate of authenticity it usually means they were in a meeting, sales numbers weren't good enough and somebody came up with this idea.
If it goes well, mark my words, there will be X series anniversary editions, unique serial numbers saved for celebrities. I don't think you can gold plate these bodies but don't rule it out.
@papa natas Wrong on this one; X10 had orb issues in early production series. Did you mean sticky aperture blades?
JohnEwing: Firmware update needed?
Likely, there will be a firmware upgrade adding 50 mm frame-lines in the OVF, right?
Early review at New Camera News:
Kevin Sutton: Anyone apart from me think this camera looks rather ugly? That faux-pentaprism is not very pretty, unlike the E-M1 version that harks back to the OM-2, which was a truly pretty camera. Cheers Kevin
I think it is a matter of visual design reference - if your past was full of OM cameras, surely E-M1 looks right. But in the plethora of film cameras from the 70’s and 80’s, you will find plenty of design similarities with Fujica (and Contax as mentioned) from the past. And in that context X-T1 looks just right.
Now, how about that; Adobe continues on the Open Source path, now also with Photoshop - unintentionally though!
Anyway; no more Acrobat Reader on my machines - seems to be one of the best documented platforms for security breaches...
victorian squid: They really should have virtual film. Instead of the useless creative effects they've got now for direct to JPG, why not virtual film? Kodachrome, Ektachrome, Velvia, Optima, Pan, and associated ASA/ISO. That would be a direct to JPG effect I might actually use.
It'd be even funnier if you had to "wind" the sucker for each shot. And, you'd have to spend extra for a battery grip that would allow you to shoot multiple shots in succession! Nikon could bleed folks an extra $400 for that goody alone!
Oh - didn't see Frank's comments below - I guess I wasn't as facetious as I thought!
...as for physically "winding the film", this was done in R-D1 - you had to do it!
falconeyes: @anybody commenting on price:
The 3000$ claim was fake, there is nothing known about the price. DPR article has been updated too.
A strong blow to Hasselblad; camera manufacturers start releasing cameras with wooden grips on their own! How did this happen? No one saw it coming...
sixtiesphotographer: On October 18, 2013, Fuji updated the firmware once again to revision 2.0
Fujifilm Finepix X100 firmware V1.30http://www.dpreview.com/news/2012/05/15/Fujifilm-WCL-X100-wide-angle-converter-lens-firmware-v-1-3-0

QuarryCat: I never liked the portrait with the peering eyes - i don't like the artificial green background - but I love his other, even more realistic picture with the hands and the living eyes - thanks a lot for showing it here!
What background? I only saw eyes...
Like the Lunar and the Stellar, this one is also a fake from Hasselblad - no matter what it will look like when released...
Now, how about that; Adobe goes Open Source - unintentionally though!
People arguing about the relevance of such a lens and about this type of news being relevant to DPReview. Well, a newly developed Petzval lens is certainly much more relevant and likely to bring joy and fun back into photography than an insanely priced Hasselblad re-branded Sony compact camera with a wooden grip. And the reviving of such a lens (by crowd-funding) is much more of photography news than the absurd marketing ploy by the investor that has taken over one of the truly inventive companies of the past.
So sad with the demise of this iconic company! What's next? An overpriced Sony Xperia phone with a wooden handle? Could be more visionary and meaningful though...
JohnEwing: The Colonel's lady and Molly O'Grady are sisters under the skin.
"The Ladies" by Rudyard Kiplinghttp://www.poetryloverspage.com/poets/kipling/ladies.html
Judy O'Grady (Molly is a typo), a prostitute, and the Colonel's Lady (and all women) are all alike, seemed to be the conclusion. Nowadays the analogy is used to point out differences that are only superficial - fits the context here quite well...
