Roger's reports are invaluable as always. They also raise the question about how 'renters' treat high quality optical equipment. I find that insightful.

Well if it is anything like car rentals...

HDR - High Dynamic Range / HDR with LR 4...
« on: September 22, 2012, 11:51:22 AM »
Highlights that you thought were unusable are easily rescued with Lightroom 4.

These three images are all from the same base image that I was going to use as part of a set of 5 for HDR because of problems with highlights.

The three images are - "from_camera.jpg" (this is the image imported into Lightroom, without any adjustments being applied). "lightroom_process_2010.jpg" is the best I could get with Lightroom v3.6. Maybe I could make it a bit better but going further requires messing around with tone curves and is quite tricky. Lastly, "lightroom_process_2012.jpg" is what I get with Lightroom 4.2

Of the three, it is the one from Lightroom 4.2 that looks the most natural and as can easily be seen, a lot of detail is recovered from the clouds whilst a little bit of saturation fills out the colours with some body.

EOS Bodies - For Stills / Re: Watch those CF pins on your 5D3
« on: September 21, 2012, 09:04:00 PM »
The pin / socket arrangement on CF cards violates rule 101 of connector design. 
Sockets go on the power side, pins on the non powered side. 
It was designed by a total klutz.

That is total rubbish.

All of these lens comparisons forgot one thing...

Nikon 14-24/2.8 $1749
Canon nothing.

With Nikon you would have to go 3rd party for most to get the price fit\

And if you read the latest blog entry on lensrentals about lens repairs, Tamron are seriously whipping Canon/Nikon ass.

Software & Accessories / Does LR4 do away with HDR for you?
« on: September 21, 2012, 09:34:39 AM »
I've been working with a bunch of images that I previously took for HDR purposes and I'm finding that with LR4 and "process 2012", I can normally work with one of the more over exposed images and achieve the look I want a lot easier. it's like earlier versions of Lightroom (and DPP too!) are hiding a lot of highlight detail.

What about others?

While we don’t use them often, Tamron even goes a step better: they guarantee they’ll have an item fixed 3 days after they receive it (I’ve confirmed this with Pat Simonetti, Director of Tamron Customer Service). If they can’t fix it in a timely fashion, they supply a refurbished or new replacement. I should also mention that when we’ve reported a problem to Tamron or Zeiss, both make inquiries about it, getting all the information they can and passing it on to manufacturing. It’s a pleasant change from “there is no problem, we never have problems.”

Now that's a company that gets customer service and gets that it needs to improve its image.

I'm really looking forward to seeing what the new Tamron 70-200/2.8 VC is like and what other lens they come out with.

Why?  The lenses.  First of all, the 6D kit with the 24-105 f/4 looks like a good deal, and the 24-105 seems like an ideal lens for walking around with a FF body.  As far as I know, Nikon has no lens that really competes with the 24-105.

Wouldn't the Nikkor 24-120 f/4 be that lens?

Great time to buy the switchers Canon glass on KEH, Ebay and Craigslist.

Why switch?

I think it's time to just buy some glass for Nikon F-mount, get myself a new Nikon branded DSLR and put the Canon glass in storage until such time as Canon finds their mojo.

EOS Bodies / Re: DxOMark Sensor Performance: Nikon vs. Canon
« on: September 20, 2012, 08:43:07 AM »
Sensor performance isn't everything...

Not only not everything, but far less than even remotely close to everything.  Consider all the glass the light must pass through before it even reaches the sensor.

Also consider that DxOMark is evaluating only the sensor, and also that their "Overall Score" is composite of three arbitrarily chosen "Use Case Scores" that are combined in a 'weighted' manner, but the weighting is not disclosed.

DxO is also capable of telling you how lenses perform on various cameras, e.g. the 70-300L:

BTW! Anyone find it strange DxO has the finished analysis/review of the D600 days after it is released? And they still haven't finished they analysis/review of the 1D-X !?
...

Nope.

Nikon had the D600 on sale via the web/stores 5 days after it was announced, so it is likely that Nikon were able to ship a production matched D600 to DxO ahead of time.

How long did it take Canon to even get 1DX cameras out to folks that were going to need them for the Olympics? And how long did it take for the 1DX to show up in stores? Don't blame DxO for Canon's inability to delivery/perform.

DXO appears to have a Nikon bias.  They haven't released scores for the 1DX, the T4i or the Olympus OMD EM-5, but they get the D600 out within days of its release.

Maybe Nikon sent DxO a D600 free of charge and ahead of time because they wanted the results up on the DxO web page ASAP?

Why would Nikon do that?

Because Nikon are smart enough to realise that they will score well on DxO and that it'll be good marketing and in general a boost for their brand and sales.

If you were DxO and Nikon did such, would you say no?

The rub here is that if you're Canon and you already know that your camera's sensor isn't going to score better than anything Nikon has published then you're not going to be in any sort of rush to have it tested by DxO. I don't know if DxO purchases the cameras for themselves or waits for vendors to send them freebies...

I have said this many times. You CAN NOT compare dynamic range on ISO100, and assume everybody works in ISO100, and that this is the correct ISO to measure by, like DxO does. I RARELY go below ISO 1600 for my kind of work.

More than 90% of the photos I take are at ISO100, if only because that's what gives me the best IQ.

Canon General / Re: Canon EOS 6D Preorders
« on: September 20, 2012, 03:53:34 AM »
What really sucks is they flaunt some of the features that should have EASILY been included on the 5D Mark III.  I went out and bought that separate GPS since I do a lot of hiking for $279.  They could have included the wireless feature as they do with the 6D and most of all, sure no one in their right mind that would buy a 5D would use a popup flash however the 7D has the pop up that allows IR for the 580 EXII (and others). Why these 3 key features were not on the 5D MK III is plain greediness. The infamous Red Line has spread and beginning to show across my forehead when I think about this stuff.  Hmmh.

There was a comment quite some time ago about how one of the hardest engineering choices they have is how to meet a specific price point with their choice of features for a given camera. Sure, they could have put WiFi and GPS inside the 5D3 but if that moved the launch MSRP from $3499 to $3699 then the inc. tax price is suddently around $4000.

So their goal is not just designing and building the camera but also including parts and materials that allow it to meet a specific price point. Would, for example, you trade the GPS+WiFi for a body that was half magnesium alloy and half polycarbonate instead of no GPS/Wifi and full magnesium alloy body?

That said, DxO is a complete and total joke. This is a company that ranks consumer DSLRs above medium format digital backs in IQ.
...

There is no rule that says a MF digital back must be better at taking pictures than a DSLR.

If the design and technology used by the DSLR is superior to that of the digital back and delivers better images then it stands to reason that the sensor can be rated above a MF back.
