On Behind the Shot: Flames of the North article (67 comments in total)

Curious about the reason behind your post processing method, why you prefer using a destructive method (i.e. using the eraser to actually delete parts of the layer), instead of doing it non-destructively via layer masks?

On Fujifilm updates X-mount lens roadmap to end of 2015 article (171 comments in total)
In reply to:

photogeek: Too bad most of their lenses have noisy, slow motors and are worthless for fast moving subjects. FWIW, I ended up going with MFT after trying both X-T1 and E-M1 side by side. E-M1 is just much better made and all their lenses (at least all I have tried) have ultrasonic motors. The only real flaw that I could see in Oly lineup is their 17mm f/1.8 lens, which, while not that bad in absolute terms, is not that good either, and worse than their f/2.8 zoom.

Does Fujifilm own or know any patent or tech to implement USM though? Any of their existing lenses have USM tech in them?

On What is equivalence and why should I care? article (2062 comments in total)

Not sure if this is already mentioned in the sea of 600+ comments, but I thought it is not the physical size of the aperture that matters, but the size of the entrance pupil, which is the virtual aperture as projected through the front of the lens?

On MIT algorithm predicts photo popularity article (97 comments in total)

The next obvious step would be to put this algorithm into phones and cameras and have it score your photo even before you press the shutter release button. T__T

On Fujifilm UK X Signature service officially launched article (125 comments in total)
In reply to:

Adrian Tung: Would be nice if they also offered alternate top/bottom plate colours (e.g. silver, black, chrome).

And if they are going the Leica route, offer engraved signature/text as well?

Including the X-Pro1 which is normally black-only?

In reply to:

Zeisschen: What will be the aperture? And what will be the FF equivalent of it?

Kelvin L, actually that is incorrect. The effective aperture is not based on the diameter of the primary refractive element, but based on a virtual image of the aperture as seen through the front of the lens.

You can refer to the section for Entrance Pupil for more details:
http://software.canon-europe.com/files/documents/EF_Lens_Work_Book_10_EN.pdf

From what I can see in image #4 of the teleconverter, what I can guess it does is increase the size of the entrance pupil, most likely proportional to the effective focal length increase so that the actual F number remains approx. constant. This is the same technique used by most 70-200/2.8 lenses where the physical iris opening is based around the 70/2.8=25mm end, then using forward element groups to increase the size of the entrance pupil as you zoom towards 200mm.

The ones you're reading are probably the ones that mount behind the lens. Those apply their multiplier to FL and aperture.

Entrance pupil diameter, not the actual aperture diameter inside the lens.

Not sure how a front-mounted teleconverter affect this though.

On Battle of the titans: Top ball heads tested article (269 comments in total)

Will there be another test of consumer-oriented ball heads for us mere mortals in the near future? I'd be interested in seeing the sag results for Manfrotto's hydrostatic ball heads.

Adrian Tung: I've seen this camera up close, it is really big and bulky for an MILC-Android hybrid.

My personal opinion, not that anyone cares, would be:
1) should have been in NX300 form factor with optional EVF attachment
2) should have provided dual memory card slots -- one for Android usage (apps, music, documents, etc) and one for frequent removal and swapping (i.e. captured RAW photos)
3) offer cellular communication (GSM, etc)*

* more of a curio than a serious suggestion... but it would be neat to be the first, no?

1) NX300 is a better form factor when using it as a tablet.

2) Like all other Samsung mobile devices, 16GB is not much at all and often requires add-on storage once you start adding apps, pictures, music, movies, etc. And ideally this content should be separated from the card used for photography which will be swapped and/or formatted often.

3) Cellular data and cellular communication aren't the same thing.

I wonder why Samsung didn't go all the way and include cellular communication. It could have been the first ILC camera-phone, a highly amusing sight to see (putting a large camera with lens to your ear) but probably not as odd as putting a huge 8" tablet to the ear.

On Fujifilm X100S Review preview (487 comments in total)
In reply to:

Adrian Tung: I don't get why this is a con: "Focus must be acquired for every exposure in AF-S mode (use AFL to get around it)"

Isn't that practically how all cameras behave in single shot mode, unless you engage some form of focus lock (e.g. manual focus, AF-L, etc)?

That's interesting, I wasn't aware of such a feature either.

Sorry, I don't follow. Let's say I decide to focus on a subject (with any camera), I half-press the shutter. It focuses and confirms lock. Then I fully press to take the picture. Now when I half-press again, it's going to attempt to focus and lock again.

Am I missing something here?

I bet someone would take this, strap the whole thing onto a battery-powered platform and make a robot out of it.

I can imagine the Rei and Asuka versions being sold out in the blink of an eye, but who in their right mind would buy the Shinji? And why isn't there a Makinami Mari edition? ;-)
