On Hungarian law bans photos taken without consent article (325 comments in total)

It may be a way to suppress opposition and protests. The Hungarian government at present is very right wing and has run already into problems with the EU (of which it is a member) about continuously eroding civil liberties and suppressing opposition. The law may well be mostly applied during demonstrations so authorities can confiscate cameras, mobiles etc. that document abuse.

well, the sensor is only 16 bit. "This new sensor is a 19-Mpix, 30.7 x 15.8mm Bayer pattern 16-bit CMOS sensor ... ", so obviously some processing.

" Sales for the Rebel SL1 have not been as great as we expected in America". I guess everything has to be supersize there.... ;-) But surely, with the obesity pandemic, small controls won't work.

I thought they use a trick to have multiple exposures at different sensitivities?

In reply to:

Abaregi: Why the small sensors in these new ones from Fuji, isn't the point of stepping up from a cellphone or compact camera to get higher image quality indoors and in darker days/nights?

Simplified: Big sensor = big lens
So, either dSLRs for big sensors, or a compromise like Sony RX100. A compact all in one with large zoom range, that's what these cameras are. If you want big sensor go for the X FUJIFILM System X-E2 etc.

ConanFuji: Fujifilm...wake up.
You've been stuck on 16MP since the F500EXR like 5 years ago.
There's smartphones with more megapixel than these!
And what's with the slooooooooooooooooooowwwww lens on pinhead sized sensors?
It's the era of the Full Frame, baby!

I guess that was ironic. You know of course how big a 1200mm lens is on FF : http://www.bhphotovideo.com/c/find/newsLetter/Mother-of-All-L-Lenses.jsp
And that at f5.6 diffraction on that size sensors limits resolution to about 3MPs...

On Tamron to develop 150-600mm F5-6.3 ultra-telephoto zoom article (193 comments in total)

Hopefully this will bring some movement into the long tele zoom market, if it achieves similar quality as the Tamron 70-300 VC. In Canon land, nothing really beats the aging 100-400 L so far, the cheaper Sigmas being worse and heavier.

Does the ISO wheel spin when the camera is set to AUTO ISO? ;-)

On Niki Feijen's haunting images of abandoned houses article (219 comments in total)

picture 9, the church. Is that staged? must be, can't believe there would be dead bodies sitting there. so, in all pictures, how much is staged, versus real?

too bad they didn't put the GPS in there that can be found in their smaller cameras. For traveling, it's nice to sometimes tag photos in remote areas.

In reply to:

abortabort: Seriously? The 16-28mm is a great lens, but 5 TIMES the price?! Samyang's cine versions are something like $50 more, if that. I suppose this will still be cheaper than the competition though.

I don't think they will make substantial better quality control on this lens - certainly not the way Roger suggests that cinema lenses need to be highly calibrated in his blog. The optical specs are the same as the normal lens, it's really just the barrel which is different. I think they look at it as a niche product, selling few copies to pros that can afford it.

In reply to:

CarVac: They may have reworked some of the mechanisms to provide for parfocal zooming. That would certainly account for an increased price.

based on the optical diagram, they are the same.

In reply to:

Jorginho: I just decided on the 84.5 filter series. Quite a few Dutch reviews by pro photographers convinced me. In general: in spite of the hard (organic) glass not scratch free, but no colour cast not even when you put two or three in your filterholder. Price is okey. So...no Cokin (creative) for me.

But a good thing they survive.

ah, nice, but not available everywhere yet. Still, they fit the Cokin P and same material as Cokin, Hitech, Lee, Singh-Ray (C39). perhaps dyes are better (no IR leak??)

Direct link | Posted on Sep 6, 2013 at 21:10 UTC

Decent price with decent quality will sell. Look at how Lee is continuously sold out, despite the high price. They just need to update for modern needs, i.e. NDs, and gradients (no color necessary usually) for photography, and sets of filters for video (effects that are not easy to do in post).

In reply to:

Hoefie: If I have a 77mm lens, what filter should I get: M, L or XL ?
As there is an overlap on all sizes; is the size really the only difference between the four ranges ?

Depends on focal length and what body it's on, i.e. the angle of view. You should get the range that covers the lens with your largest front diameter, taking into account the angle of view. I.e. on a tele, you can stack a bunch of 77mm filters with little effect, while on a wide angle, a thick filter (e.g. variable NDs) may already give hard vignetting.

Richard H Goodman: GOOD! Maybe I can finally get a 77mm P series adapter!

What's the problem? For a few $ you get a 77mm adapter ring plus P holder on ebay.

Well, despite the advantages of dSLR, a nice print on good quality film paper should last a long time. In that time you have to keep buying new technology every few years and copy your stuff again and again if you want to save it into the future. Hopefully some new stable technology will come along. I thought CDs and DVDs would last, but seems they don't. (hard drives fail of course routinely).

On Battle of the Wi-Fi Cards: Eye-Fi vs. Transcend article (178 comments in total)
In reply to:

photonius: What about the Sandisk Eye Fi cards? Is this simply a licensed version of the Eye-Fi card with the same software and features as described here, or are there differences?

Thanks for the info on the Sandisk. Yes, looks like the Eye-Fi itself is not readily available in europe. hmm, if nobody wants to sell a decent product, so be it, they won't get my money then.
