Sean65: Don't get these articles. What are they? Some kind of camera geek porn?

I'm also at a loss a bit as to why we are force-fed these iFixit posts all of a sudden. Twitter streams need to keep on trickling, but it's kinda lazy to constantly "lend" one source's work.

Criticizing is easy of course, so I'll contribute an alternative "article", for those owning/buying old Sigma lenses that don't work with recent Canon bodies. Famously, Sigma used to "re-chip" some of these lenses, but they soon stopped doing so. Obviously some people are brilliant, and managed to back-engineer a solution themselves. Here is Martin Melchior's how-to guide:
http://www.martinmelchior.be/2013/04/conversion-of-old-sigma-lens-to-work.html

It is mentioned that you can order pre-programmed chips from a helpful Czec person here:

Not being knowledgeable enough about soldering myself, I mailed my Sigma 400mm to him, and got back a fully functioning one for a VERY reasonable price.

Greg VdB: Interesting analysis, thanks. I guess it's too much to hope for an equivalent function being added to my Eos 70D through a firmware upgrade?...

My thinking exactly.

Greg VdB: Ok ok, we get it, iFixit is a *great* website! :-) (fourth link to them in a month...)

In case you look for other interesting material to post, please take a look at LensTip - the most comprehensive lens test database I know. For instance, a few days ago, they published their review of the Tamron SP 85mm:
http://www.lenstip.com/index.php?test=obiektywu&test_ob=472

After 2013 DPR has managed to produce only a handful of lens reviews (5 in 2014, 1 in 2015, 2 thus far in 2016), so I don't see the (also more detailed) LensTip reviews as direct competition ;-)

Thermidor: It's an oxymoron to claim USB charging is convenient and inconvenient at the same time. If you're running multiple batteries, you'll get an external charger anyway. And to be very fair, USB charging the FW-50 battery is a LOT faster than using an external charger. By USB, I can get full charge in slightly over an hour versus about 3 with a dedicated charger.

I know ideally the camera should support USB charging AND come with a dedicated external charger, but I don't see any manufacturers doing this. So if I had to compromise, I'd rather my camera come with USB charging than not.

Spaspa, you're right about that. But I never even considered that a negative, since I prefer to be able to use my camera on a spare while charging an empty battery. That said, my cheapo Panasonic travel zoom (a TZ7 if I'm not mistaken) DID come with an external charger while also being capable of being charged by usb.

My 70D, which is in the same price class, came with an external charger, as do many other cameras. Also, if charging by usb is quicker than by external charger, then there's something *very* wrong with that external charger...

In reply to:

superstar905: Richard, I am impressed that you come here and respond to criticism levelled at the review. That is big of you, and speaks to your confidence in what you have delivered. I wonder if the camera should have gotten a silver or a Gold based on factors others have mentioned specifically lack of direct access to functions without having to menu dive, lens ecosystem, etc. That said, this camera is clearly an upgrade, and clearly the best in its class and for those complaining about the price (I'm not thrilled about it either), just look at whats being charged for the Olympus Pen F and X-Pro 2 both of which are inferior to the a6300.

@Richard: your description of the decision making process of gold versus silver awards suggests to me that handing out these awards is just the wrong thing to do. In my humble opinion it would be much better to drop the awards and the "final score", and just present the category scores together with your final conclusions and "good for, not good for" summaries. DPR stands apart from the crowd because of their highly detailed reviews, which is something you deservedly pride yourselves on, so why then spoil this by going down the populistic route of over-simplification at the end? DxO makes the same error, btw, trying to represent complex products by one single number...

I've always liked the dark scheme as I find it easier on the eyes and better for looking at pictures, but it's good you give an option to those with different preferences.

Greg VdB: Since it's an RX10 II with a longer lens, not replacing it, surely the logical name would have been RX10 II XL...
(leaving room for a future version with an even longer lens, the RX10 II XXL, and so on)

Go check the PlayStation Gear shop ;-)

In reply to:

mosc: now that we have the speed graph, I still prefer the RX10m2's lens to the RX10m3's. Reach is overrated and it's a stop slower through most of the zoom range. The f2.4 is nice at 24mm which I do shoot a lot at but even at 28 it's slower.

Androole, it was added to the announcement post. Here you go: http://www.dpreview.com/files/p/articles/0414918604/RX10_III_equivap.png

In reply to:

cgarrard: Ok it raised my eyebrows :). Sony's good at doing that. I'd like to see a bigger grip, the RX10's is too small, and I fear this one isn't much different.... with a much longer zoom now and heavier camera, the grip size should have been increased for stability and comfort.

And get rid of those post strap lugs, they dig right into the shooting hand.

Otherwise, a very nice effort again Sony... I'd bet this price will drop fast, 1299.99 seems more likely when its on the market for a bit. Give it a year it will be sub 1k, and people will start eating it up.

Unless Panasonic comes out with the FZ2000- weather sealed, longer zoom..... :)

Carl

at least the grip seems better sized than those on many of the Alpha bodies...

No matter how big or small the differences are, they will be enlarged and vehemently discussed by the resident pixel peepers and fanboys. Here's a shot I recently took with that terrible 70D: http://www.pbase.com/gbleek/image/162812389/original From a great day of snowshoeing and photography that I didn't waste in endless online discussions...

In reply to:

pulsar123: This lens looks more modest (at least on the paper) than the upcoming Venus Laowa Zero distortion 12mm f2.8 FF lens (https://www.flickr.com/groups/2876587@N24/). Laowa has one extra element (16 vs 15 in Irix), the same number of aspherical elements (2), and apparently negligible 0.2% distortion. All that with the substantially wider angle of view (122 degrees vs. 110 degrees), albeit a bit slower (f2.8 vs. f2.4). And Venus already has an established record of interesting quality lenses (60mm 2:1 macro, 15mm 1:1 macro, and the just announced 105mm STF f2.0). Also I suspect the "Swiss" lens will come with a heftier price tag, but we'll see.

Well, that looks like an interesting lens too. Always room for additional options! ;-)

Some intriguing features for UWA astrophotography - a 'click' at infinity in combination with camera-specific focus calibration, a focus lock, weather sealing, fluorescent markings. It all depends on how well optical aberrations and vignetting are controlled of course, but the f/2.4 maximum aperture means that it can be stopped down slightly (and hopefully improved) before it matches the typical f/2.8 of the 14/15mm competition. At the rumored MSRP of €549 (per D135ima's comment below) for the Firefly edition, this certainly got my attention!

I don't like excessively lifted shadows, but as someone who dabbles in astro and timelapse* photography (*often shooting into a rising or setting sun), this will still make a substantial difference for my photography.

In reply to:

Aroart: I find it amusing that people need to nit pick this camera vs the d7200... Yes the d7200 might have a bit of an advantage in photo iq but the fact of the matter is more people that are buying these semi pro cameras will lean towards the 80d purely for it flippy touch screen and great video auto focus...

The D500 that is in a completely different price range?

On article Sony a6300 gallery updated with Raw conversions (137 comments in total)
In reply to:

Luddhi: When I look at the Gallery the photos labelled RAW in the thumbnails show as OOC Jegs in the sidebar—and vice versa.

Here's an idea, Richard: just put a "JPEG" tag on, you know, OOC jpegs, and a "RAW" tag on, you know, developed RAWs ;-) It's usually plain to see from the Gallery bar or grid overview which photos are jpeg-raw pairs. And if you also introduce similar overlay tags for "iso" and "aperture" series, there can be no confusion.
