Very talented pilot... who is going to incite banning of drones in yet more places. Aside from any issues of interfering with the train, this clearly violates the usual requirements about keeping the drone in line-of-sight and is just plain irresponsible. I wonder if he'll be prosecuted?

Looks pretty good. Don't get the "Angle of View (MFT-4k): 220 x 150" spec. -- it's 220 degrees in a 10mm circle, which doesn't seem like it is clipped to 150 degrees in the vertical by the 4K 16:9 aspect ratio...?

Still have mine and it still works. Had some build quality issues: lens always wabbled and it lost some parts....

One of my worst lenses by most metrics is a Soligor 135mm f/2.8 with 20 aperture blades: https://www.instructables.com/id/M42-Lens-Aperture-Control-on-Modern-DSLRs/

Yeah, it makes a very circular aperture... but the blades are shiny enough that IQ gets continuously worse as you stop the lens down due to reflections off the blades horrifically dropping contrast. Then again, I don't feel too bad about it because my very pretty Soligor cost me $10, including front and rear machined-aluminum lenscaps and the custom wood case it originally came in.

Suave: This is nuts. Ebay is chock full of various Biotars. What's next? Legendary Domiplan 50/2.8 for $800? Or Legendary Pentacon 50/1.8 for 1200?

Rensol: Plywood? You clearly don't understand. It should at least be hand-rubbed oiled bird's-eye maple, or perhaps your choice of exotic: padauk, bubinga, bocote, wenge, katalox, or purpleheart. Drill? No, hand-cut joinery. Then the final touch is you put a 3-year-old Sony camera in it and laser-engrave the Hasselblad logo on the outside. ;-)

gorllu: Promoting photographers based on their skin color? That is racist af.

Our society reached the point, where promoting chocolate is diversity friendly and promoting any kind of milk is racist. West is strange place to live...

I think they used "of color" mostly to mean "not white" -- I personally don't like such phrasing and I certainly get the irony that they're increasing diversity by excluding a group. Still, it's always difficult to identify precisely who is worthy of an extra opportunity because the more common paths unfairly excluded them. I think the website is trying to live up to the Diversify.Photo name. So, you can count me as one white guy who respects what they are trying to do, despite not loving every detail of how they are doing it.

They do say "photographers of color," but they clearly don't really mean of just one particular color. The site actually seems to be promoting photographers from various commonly underrepresented groups spanning various ethnicities, genders, and types of photographic tasks undertaken. Looks truly diverse to me.

Father Bouvier: Yes, I can see it. Zenit is going to buy Leica parts, and Sony sensors ... and sell $100 bodies. God bless their generosity.

Leica isn't exactly an electronics powerhouse. They buy their sensors from a variety of vendors... or so various websites say. So, I'd be surprised if Zenit goes with Sony sensors. No problem; there are plenty of other sensor makers.

Incidentally, Zenit says it will be "more expensive than a good smartphone" -- so not a $100 body. :-( That wasn't realistic anyway, but it might be a competitor for Sony's A7....

On challenge Grounded (2 comments in total)

I see a few entries that see to be things on the ground... that's fine, but ONLY as long as the camera was also on the ground. If it isn't obvious, I'll give you the benefit of the doubt -- but I will disqualify shots clearly taken with the camera not sitting on the ground.

Chris Dodkin: "Olympus, Sony and Fujifilm can only cover a small part of that. So far there is no professional using their products."

I can understand them saying this for BS marketing purposes - but if they really believe this, then they are in deep deep trouble.

Father Bouvier: The "prepare a response to current market needs" approach is a great way to be late to market with a "me too" product -- while a leader like Sony takes an engineering-heavy approach of being willing to invest in many things that might (or might not) define the future of cameras.

In fairness, I think Nikon took a good forward-thinking shot with the Nikon 1 line. The problem is that when it didn't immediately hit, rather than trying many things, they became very risk adverse. It's not that Sony has had better luck -- it's that Sony kept trying different things... and they keep trying new things even when they have successes. Here's hoping Nikon will learn to invest more in the future....

Nikon is based in Egypt? Must be. Here they are standing in de Nile. ;-)

Actually, I think it's even more sad that their reason for full frame is "full frame is the trend" -- that's basically saying well, all the other cool kids are doing that, so we better too. Hard to lead by following.... :-(

On article iPhone X vs. Samsung Note 8 (379 comments in total)
In reply to:

Sam Bennett: The Note 8's screen, like the Note 7 is also a Wide Color Gamut screen, so not sure why you're giving the advantage to the iPhone here.

http://www.displaymate.com/Galaxy_Note8_ShootOut_100.htm

Yeah, there's a lot of nobody-notices-until-Apple-does-it going on here. It almost sounds like Apple is first with AMOLEDs, when in fact they're a late adopter by years; Samsung makes them and has used them throughout the entire Galaxy line. In fact, while Samsung had a few much-publicized battery fires, many iPhone batteries were expanding enough to burst the phone case (including both owned by my family members)... but the Apple problem never even made the news. This remarkable ability to always be perceived as ahead is why I say the best Apple thing you can buy is their stock. ;-)

The truth is these models are very competitive as good, but expensive, smartphones. I'm very curious to see if the Moto Mods and RED concept of the cell phone as the standard processing-and-GUI module that connects to various other gadgets becomes the next big thing....

ProfHankD: There aren't that many modest-cost 100-400mm options. After looking for a Minolta APO for $250, I just got a clean used Phoenix 100-400mm f/4.5-6.7 for $60.

IQ is not bad, even at 400mm: https://www.dpreview.com/forums/post/60117907

I don't see a price quoted, but the real question is how much money for how much 400mm performance? There are lots of cheap good zooms up to 300mm....

Just to be clear, I have absolutely no problem with paying for IQ I can't get any other way. For example, my Sony STF 100mm is worth every penny of its $1500 price... and I would consider this Tamron to be modest cost at $700 new.

The catch is that there are lots of cheap zooms that do well up to near 300mm, but longer than that IQ seems to fall off a cliff and pricing goes up dramatically. I'm not sure $800 buys a zoom that delivers more at 400mm than my dirt-cheap Phoenix. For that matter, a $150 1.4X teleconverter (ok, just one of several I've tested is really good) on a shorter zoom costing under $300 new might even match the IQ (I haven't measured yet). What I'm really wondering is when these long zooms are going to start being optimized for IQ at the long end, rather than the short end or middle.

DPReview sure loves fast AF, but I was fine with manual focus being the only option for half my life and I still actually prefer it for most still photography. The ability to use the AF hardware to pull focus in video is a big deal, but I still shoot more stills than video.

However, let's be blunt: this superzoom defines a new level for a fixed-lens-one-camera-does-it-all package. Judging by my RX100V, the 1" sensor can't match the tough-lighting IQ of a modern Sony APS-C sensor, but it's more than competitive with MFT and many (especially older) DSLRs... and yes, it is a serious video and sports camera too.

It will be very interesting to see who buys these....

On article Yashica is teasing a comeback to the camera market (299 comments in total)
In reply to:

Tons o Glass 0 Class: Don't get your hopes up. So far it's just a 2-in-1 wide angle and macro attachment for smartphones. The camera in the video appears to be an old Electro 35 and nothing more. It still has rangefinder windows and a film compartment!

The box art for the smartphone attachment may be teasing a camera module - a dual lens camera styled like a TLR - for smartphones. But it's more likely just box art for the 2-in-1.

You didn't read what I wrote: "somebody is going to want a NEW film camera to put their new rolls of Ektachrome in...."

As for me, well, I already have perhaps 50 film cameras... most via eBay as "lenscaps" on old lenses I bought there. No hipster cravings at all. However, sales of things from Lomo, etc., say there is a market....

"A camera like Electro 35 is by far to expensive to make."

Is it? An Electro 35 might be, but one very much LIKE it might not be. ;-)

I agree; nothing suggests a digital camera is coming here.

The interesting thing is, it would be perfectly possible for them to start selling an Electro 35 film camera as a new film-based model. After all, somebody is going to want a new film camera to put their new rolls of Ektachrome in.... ;-)

In reply to:

photonius: Nicely done. Yes, there are many ways to go beyond 1:1, as was frequently done in film/manual focus days (see also https://photonius.jimdo.com/macro/). Maybe some of that knowledge got lost in the digital area. I guess the key here is when Meike etc. released the automatic adapter to control a reversed lens about a year (?) ago. Before, only a below/adapter from Novoflex was available, though already for quite a while.

Nice photos, but there are lots of cheap ($10-$100) old manual lenses that, either forward or reversed, work very well on a bellows up to about 5:1. It's easy to get a bellows for $20-$50 and a plain reversing ring for under $10. A suitable ring flash is about $30 (and you can block parts of the ring if you wish creative control of the lighting). Not really a big trick to this.... BTW, mirrorless works much better for this partly because of the focus aids, but also because EVF brightness is still fine stopped down so you can see the actual DoF (OVFs get unusably dark).
