RCicala: Several people made the pertinent comment that they would expect some effect in sharpness and contrast. I took a Batis 135mm f/2.8 lens, MTF tested it first with no filter, then with a B&W Multi-coated clear filter, then 5 of the CP polarizing filters.

The clear filter made no difference.

All the polarizers (B&W, Marumi, Zeiss, Tiffen Ultra, and Helipan) caused a slight decrease in MTF at high frequencies. There was no change at 10 and 20 lp/mm. At 30 lp/mm there was a consistent 1-2% drop, by 50 lp/mm it was about 4%. I could detect no difference between them.

This is a quick check. I'll look at things in thoroughly when I have time. But the bottom line is fine detail in photos is affected a bit. I don't find that the least bit surprising.

I've also ordered a couple of $40 filters and we'll see how those compare. As has been pointed out, this was a group of filters that were all expected to be good. If the $40 filters are the same, then I'd be surprised.

@ sharpbokeh. Please refer to the link I posted above and judge for yourself if they degrade image quality and, if so, to what extent. Then it becomes an issue of whether the minor sacrifice is outweighed by the need.

Looks like most of us missed an earlier post by FrancoD, where the real product is more likely to be a smartphone lens.

BarryAurora: What a rush of nostalgia! My first (1961) 35mm camera was a 'Yashica J' .. 45mm f/2.8 fixed lens with split-image rangefinder. By 1967 I'd dabbled into 2 1/4" square with a Yashicamat twin-lens-reflex. Both cameras found their way into trade-in/pawn-shop when I opted for old (even then) Canon range-finders (screw mount) with Leica lenses .. of which my favourite was a 50mm f/2 collapsible Summicron.

OMG, I'm awash with that nostalgia!

I'd be thinking a Yashika (sic) branded camera was a knock off. I'd want to buy the real thing made by Yashica. :D)

Benjamin Kanarek: I loved my 6 x 6 Yashimat!

As far as I have discovered there isn't a Yashimat. In the early days there were Yashima Flex and Yashica Flex, and prior to these Pigeonflex. Here is a very informative site with nearly everything there is to know about Yashica production. Paul Sokk would seem to have spent a lifetime devoted to Yashica TLR cameras.

RolliPoli: A digital Yashicamat?..... I'm buying!!!

Dream on! :D) Lovely thought, though. No, I'll keep my clockwork shutter, geared film advance, focus confirmation using human optical system, IS using a geometric positioning of my arms, and just 12 shots per load. Now this is a proper YashicaMat, and any other TLR come to it.

Lichtbild: So there will be a full-frame range finder with a bayonett from a new camera brand. Great! More competition is always better.

Does it necessarily have to have an interchangeable lens mount? This really complicates matters and puts up the price. And then they are committed to making a range of lenses and then, no doubt, we'll get complaints and reviews similar to those bandied around about Sony Nex/Alpha and Fuji X at their launches that lens choice was limited.

Copal Fit: Maybe this question was raised in earlier comments already - but why do viewers think this might be a digital camera to come? At 0:07 seconds of this video you can clearly see that the actor moves the film lever of the camera - no digital camera needs this piece. Judging from this, it seems more likely that the brand considers a remake of a 35 mm film camera.

But this is because an original Electro camera is being featured, I suspect to generate nostalgia and interest in whatever the brand has in mind. More intriguing is the actor using the camera as though to take a selfie, something physically impossible to do unless she has arms about one metre long.

The retro designs of late, Nikon and Olympus for example, have still only hinted at their forebears. Leica comes closest but anyone can still see they are quite distinct from the film M's.

The Yashica Electro cameras are big and heavy beasts, but their size alone would mean modern digital innards could easily be accommodated with ease. Now if Yashica did do this to an Electro body, I'd be somewhat gobsmacked, but I'd guess it would generate enormous interest, and if they kept the price reasonable, who knows where it could lead. If, however, it turns out to be another "like me" camera just badged Yashica, it's likely to be a bit of a let-down.

But then, it could be a film camera.

ozy82: Why didn't they give the award to the Thai photographer? Image was winner after all!

Sadly, for him, he didn't enter the competition, so there is no logic to his receiving the award. Should the photographer who came second be awarded First Prize? Even this could be debatable as that image wasn't thought worthy of first place.

The knock-on effect of fraudsters goes beyond the initial action. We've recently seen a number of athletes being stripped of their medals following drug tests. Whilst this is belated justice, and the "clean" athletes got their medal upgrades, it robbed them of the joy of being presented with the medal at the event in front of the spectators and millions in the TV audience.

Sezano: 337g. I got to say, as a dentist, I love this.

I'm truly curious. Why does being a dentist make any camera attractive to you? If this is a factor why not got one of the Yashica Dental Eye film cameras specifically aimed at your profession?

Wye Photography: I am glad I live in the UK.

@ Resom. Of course, there are always two sides to a story. How about this one, then you may be able to form a more informed view of why the UK voted Brexit. I'm sitting on the fence as I didn't vote. My heart was with Brexit, but my head was with remain. The EU needs reforming, but I don't see how it ever will. If Brexit achieves anything, it certainly shook up the European Commission! :D)

Wye Photography: I am glad I live in the UK.

@ Franz Weber, with hindsight xenophobia was unnecessary. I'm sorry. The thing is, with English as a second language no matter how fluent one may be, all too often the nuances of speech or the written word can not always be appreciated or understood. In your original post in response to Wye Photography's upbeat and optimistic "I'm glad I live in the UK" you replied with what can be seen as a somewhat negative and derogatory view of British food. Sadly, this is a common jibe by people who know no better.

Whilst one can find reasonable food on the High Street, and in my home town we can boast a plethora of international style eateries, many of which I frequent, one has to search for the next level. In a large city you will find them, but more often than not one will find them out in the country in many pubs or small towns where local produce to a high quality will be found. It is there, if one has the inclination and time to seek it out. Mit freundlichen Grüßen

BadScience: This is a cultural issue, not a political issue.

The right to keep bear arms is deeply ingrained in the American psyche.

The issue is far beyond rational debate: the number of people who will change their minds on the issue, even after the umpteenth mass shooting, or accidental shooting, or rampant gang warfare is negligible. This goes both ways - the issue is polarising, with conveniently picked statistics thrown around by both sides.

Cultural change does not happen by political debate, or political will, it happens gradually, incrementally, over generations as society changes.

Who knows? The citizens of the United States may become more ever-more-armed as they see their culture attacked by perceived or real threats; as they see the individualism of their culture eroded. That's certainly a possibility.

What is not a possibility is Americans giving up their guns because of incidents like this; or even horrors like Sandy Hook.

@ BadScience,

Whilst I knew US citizens had a right to bear arms under your Constitution, I've only now read up on the Second Amendment. I was a little surprised to learn that it used ideas in the British Bill of Rights, 1689. Whilst the times then were, politically an internationally, more volatile than today and the right to bear arms is more understandable in light of this, what is less explicable is how the US and the main English speaking group of nations* - the UK, Australia and New Zealand taken as a bloc, diverged on this concept of bearing arms. We, that is the UK, Australia and NZ, did not follow the example of the US. I'll leave the Ph.D to someone much better informed on the socio-political and economic reasons as to why, but I do find it an interesting turn of events.

* I've left Canada out of the equation as though their right to bear arms is derived from the Bill of Rights 1689, I've no idea how prevalent it is.

Graham Austin: You know what would have stopped this?
No guns! pretty damned simple, the US is so backwards in so many ways still.

For anyone reading Steve Ives' comment above, rest assured this is not the case. He is clearly one severely maladjusted individual and who seems intent on fomenting political and social unrest for his own ends.

Tony Bonanno: As an ex LEO, these shootings are very disturbing. Yes, a police officer has a difficult job and it's getting more and more difficult with the increasing level of weaponry and violence exhibited by the bad guys. But, much of the problem can be traced back to training and supervision. Tight budgets (for training and recruiting quality candidates), poor supervision and a post 9/11 military attitude have set the stage for these tragic incidents. There are many options that just don't appear to be exercised any longer.. it's more about engaging the enemy, not about serving the public and having the training and experience to take cover, assess, deescalate, etc. Shoot - Don't Shoot training scenarios use to be one of the most important components of LE training. Of course, every incident has two sides to the story. Most public safety officers are conscientious and try to do the right thing. But there is certainly a pattern that is cause for concern.

Tony Bonanno, "..a post 9/11 military attitude.." and "..it's more about engaging the enemy, not about serving the public.)

These are very insightful comments. When Sir Robert Peel set about setting up and organising the British Police service in the 19th Century, he specifically wanted to distance the new Force from the military and is why he introduced the dark blue uniform we see today and, importantly, why the constables were not to be routinely armed, nor given higher military ranks, such as Lieutenant or Captain, although sergeant does linger to this day.

His thinking behind all of this was for the Force to serve and engage with the public and not be seen as a force of control as hitherto the British army had been, the Peterloo Massacre, for example. His philosophy is followed even to this day, despite the presence of on-street armed officers being more prevalent due to the on-going terrorism threat.

vinrouge0: Flash sync speed? Base ISO? I have owned the XE-1 and 2 and even sold my X-T2 to go back to the X-E1. Just something about the output I preferred from version one. A nice upgrade but I would like to see a base ISO of 100 and flash sync of 1/250th

I'm not sure if Fuji is being a little conservative by quoting a 1/180 sec. flash synch speed, as I've tested my X-E1 and it synchs up to and including 1/250 sec. Is this unusual? Or can other users make the same claim?

But getting back to the X-E3, the lack of a tilt screen in this day and age is a disappointment and despite the obvious improvements since the X-E1, it precludes my considering updating. I also have an X-Pro 1 and the X-E1 is the backup. It would thus make a lot of sense when using them in tandem for one at least to have a tilting screen.

Although I'm not a keen advocate for on-camera flash, it is always handy to have in an emergency for fill-in or backlit subjects, and its omission here is more of a loss than having to fiddle with attaching the little external unit that comes with the camera, and by which time the moment could well have passed.
