On Panasonic Lumix DMC-LX100 Review preview (658 comments in total)
In reply to:

armanius: I'm enjoying my LX100. Unless I'm missing an option somewhere, the auto-ISO implementation is horrible. Camera refuses to go past ISO 1600 even when the shutter speed has dropped to 1/8" at full zoom (when in aperture priority).

I don't have the camera but I am interested in it. In the manual (p.137) says that you can set the Auto-ISO upper limit (contrary to what dpreview says at the Auto-ISO section of the review on page 5). Where is it set in your camera?

On What is equivalence and why should I care? article (2067 comments in total)
In reply to:

falconeyes: 18 hours ago, David Jacobowitz made an argument that this article should cite work which helped evolve the concept of equivalence (or how I call it, the equivalence theoreme).

To this end, I observed that the concept was missing in internet discussions dated 2007, Jan 11. At that time, Daniel Buck in http://www.fredmiranda.com/forum/topic/544062/ described the Brenizer method on the Fred Miranda forum (actually before Ryan Brenizer "invented" it; he did not). The effect is easily understood using equivalence (stitching effectively creates a larger sensor). Yet, the fredmiranda discussion fails to recognize this relation and does a poor job explaining the effect or compute its effective aperture.

Therefore, I think it is safe to assume that the equivalence theoreme was discovered after 2007 January. Moreover, this is a nice example how useful the equivalence theoreme actually is ...

Check this thread from 2006:

In reply to:

Mark Forman: It seems possible that the use of the Metabones adaptor might be skewing the back focus slightly. The 5D3 appears to be slightly sharper across the board.
Is it possible to repeat this test using native lenses?
In my personal experience with adaptors it is almost always a slight tradeoff in this respect.

@Rishi Sanyal

"This test was initially conducted using native lenses, but because of obvious exposure differences - despite matched apertures/exposures"

If at the same exposure settings (F number, Shutter speed) the sensors saturate at a different point you should choose different ISO to match the saturation point or you should normalize the "exposure" in the raw converter. The strict ISO number doesn't play crucial role (even for this comparison). That is at least how I think when I shoot.

Thanks for the test :)

In reply to:

Don Karner: Why do we mess up photos on purpose?

Is is called style? Or what?

Because it (messing with photos) subtract realism. And realism kills abstraction. And abstraction is one of the most important ingredients of art.
By using a modern low-noise, super crisp camera with faithful color reproduction is difficult to overcome reality and come a step closer to abstraction.
That is the reason for the revival of old techniques. Convenience.

On Fujifilm X-T1 Review preview (587 comments in total)
In reply to:

exdeejjjaaaa: http://home.comcast.net/~NikonD70/Charts/PDR.htm#OM-D%20E-M5,X-T1

There is something wrong with that EM5 graph. It is almost a match with the Ideal 4/3 graph. This isn't happening for any other sensor size. Bill Claff's excellent page needs data from another current top m4/3s performer (EM1, GH4) for reference IMO. Anyone willing to contribute?

X-T1 is where it should be. On par with the best APS-C sensors:

Tourlentes photographs remind me Robert Adams' "Summer Nights".

At last something interesting. Thanks :). The photographs are good without the need to know that there is a prison somewhere. But maybe the photographer is a little insecure about his pictures (which IMO are good) and try to add some value by revealing his motive? Anyway thanks again.

In reply to:

undergrounddigga: Funny that, every other company is trying to emulate Oly's design of the OMD .. whilst Oly users wish they had a mirrorless (PEN) camera with the viewfinder in the corner :)
(or perhaps people would want both type of cameras).

I'm not a fuji user, but from a design point I much prefer X100 or X-E than this.
X100 with its dual viewfinder is just stunning, only if they released a 50mm (FF equivalent) F1.4 with speedy autofocus ..

@Zvonimir Tosic. Dear fellow forum member. Excuse me but I really don't have the time to start a meaningless conversation.

It' s not Olympus design. It is how cameras designed and looked for decades.

In reply to:

yabokkie: very like GX1, marketed as a high end with compromised features.
don't know if it has same capacity for deep price plunge as GX1.

If you want to be successful in bashing a camera you have to say something that is believable, something near the reality but a little uncertain or something that can be difficult to prove. Saying that GX7 has compromised features won't work. Try harder.

On Nikon Df preview (2817 comments in total)
In reply to:

Hugo808: Trouble is, if you aren't using lenses with an aperture ring you still have to use the command dials which is kind of what they are trying to get away from with all this retro stuff, or am I wrong about that?

Seems to me that having an aperture dial will be a lot more useful to most than a shutter speed dial, I had one of those on an old Contax and didn't use it once!

Ah well, each to their own...

From what I see it has a double interface. Two command dials and/or dedicated shutter speed dial + aperture ring on the lens. If you use a manual lens with aperture ring you set shutter speed from the dedicated dial or one of the command dials. If a modern AF lens you can use the two command dials as any other Nikon DSLR.

On Retro Nikon 'DF' emerges from the shadows article (1396 comments in total)
In reply to:

viking79: Quick question, I didn't save the specs from Amazon, does the Df have live view? This is related to its lack of video option.

It has LV. There is a dedicated button in the back.

Minolta Dynax 7, 2000, first modern reflex retro style and direct manual controls for all.
Konica Minolta 7d, first digital reflex retro style and all manual controls, 2005!!
And now 13 yars after, Nikon.
AHAHAHAHAHAH.
Nikonians, you are so fun!

What is Minolta and what is Konica?

On Eyeist serves up portfolio reviews digitally article (12 comments in total)
In reply to:

absentaneous: frankly, I've never really understood the point of paying someone to tell you what's their taste.

Every serious collection of images has most probably pass through an intensive editing and organizing stage before being presented in a book, a website or an exhibition space. I have attended portfolio critique and organizing seminars and I was shocked about their not just usefulness but necessity. It is amazing what a experienced editor can do with a photographer's images by selecting a subset of them and by putting them in the "right" order.
The service provided by eyeist is something much needed IMO.

Is there any information if there will be a SDK to access the camera core functions and controls?

Direct link | Posted on Jun 20, 2013 at 20:22 UTC as 61st comment | 2 replies

I thought it would be much more expensive. I was wrong. It make a lot more sense now against a FF with a 24-70 f/2.8. It gives APS-C a big boost.

ADDED: At this price exposes other lens manufactures on their pricing policy.
