The top image is simply stunning ! Very MF, a good example of how far digital has brought the smaller format.

One of the many ghosts of railways past in England, this one is in the East Riding of Yorkshire and used to connect small towns and villages who's road communications are now choked with cars. Remarkable lack of foresight by the Dr. Beeching era.

5DII + 24-105L @ 105 mil f4 iso 640.

Nice work!

Thanks Carl !

Now I've found that location I'm planning a proper shoot there, based around a beautiful girl and an equally beautiful white circus horse. Will post a few when it's done  ;)

Verdict:  After careful consideration, I think I still want this lens (in a G.A.S. way), but even at that great price, my money would better be served elsewhere.

That's a pretty fair summary and why, in my opinion, we won't be seeing a revised version of the current 135L any time soon.

It'll certainly be something "completely different" from other digital MF: it won't exist. Even though Sony appears to be trying the 'scatter gun' approach to camera systems I cannot believe they will want to develop a system that's in a segment of ever decreasing market share and something of a niche area now. They havent been able to make much inroads into the Nikon/Canon upper end of the DSLR market let alone MF.

I think this rumour's about as credible as the Canon MF one  - CR 0.

Zion National Park.  The Watchman stands near the entrance to the park above the town of Springdale which lends its lights the the mountain. 4:30am,  6D. 30 sec, f4.5, ISO400, 28mm (24-105)

Beautiful shot.

Very nice image. Well done Sporgon.

Thanks Click and Rienz. I have always been fascinated by disused railway lines; this one feels particularly special, maybe because it runs between an ancient sacred spring and the site of the largest pagan temple in the North of England circa 600 AD, or maybe it's just my imagination !  ;D

I will take criticism openly. I am here for that.

1dx. Zeiss 35mm f1.4

I like this picture: the two bicycles are really sharp and this offsets the smooth bokeh of the background. The track disappearing in both view and focus suggests the 'bikes have come from, or are going somewhere together. The roses in the basket of one bike suggests a man and woman together, and the picture asks the viewer to question where they are when it's being taken.

There's also a huge EV range. I'm not sure if you've reflected or filled the 'bikes but the range has been dealt well with by both the photographer and camera; another couple of stops of DR wouldn't have held sky detail when shooting straight into the sun.

This is my Dr Bean analysis of the image  ;)

EOS Bodies / Re: Canon's Medium Format

Camyx today:
Sony medium format camera is in the works and coming soon
Sony has been supplying 50-megapixel CMOS image sensors to both Hasselblad and Phase One for their new medium format cameras. Furthermore, the Pentax 645D II will employ the same sensor. Enough is enough, says the rumor mill, as a Sony medium format camera is allegedly in the works and could be announced soon.
I'd be amazed if this was true. Sony need a MF system like a hole in the head. MF is shrinking fast and becoming more niche based on the sales volume of MF units. They may have the sensor tech but to date have been unable to meet Nikon & Canon head on with the volume gear, in fact generally not accepted yet at that level, so I can't see where they intend to be with MF.

Larger sensors also create their own issues from a user point of view; 35mm proved itself to be by far the best balance between IQ and flexibility, that has now been given a massive IQ boost with digital, so I personally don't see a trend in sensors larger than 'FF'.

I hadn't spotted this thread, but have just read through it now and have enjoyed what's been said on both sides of the 135L argument.

Personally speaking, I find the 135 mil focal length a bridge between two stools; it's too long to be as universally flexible as an 85, and not long enough to be as useful for medium tele reach as the 200. In my experience a fast 85 can create an equal 'look' courtesy of its fast aperture and a longer, slower lens the same thing courtesy of it's greater magnification.

I can get exactly the same 'look' with my 85 1.8 or 200 2.8. These lenses are much cheaper, smaller, lighter and less intrusive than the 70-200II and there's a reason for the 135L, but if that's the reason for purchase I'd go for a 200 2.8. ( Its about one third cheaper than the 135 too). In fact I did sell my 135 and kept the 200, but of course neither have IS. 

Also with modern cameras the extra stop allowing faster shutter speeds isn't as pertinent as it was due to high ISO performance.

Animal Kingdom / Re: Portrait of your "Best friend"

Just to be clear about it: this is my wife's best friend. The animal is treated considerably better than me; it gets breakfast in bed every day, has it's hair brushed and a warm coat 'n scarf put on in cold weather. It's only got to cough or get a runny nose and the doctor is summoned immediately. While I just have to suffer.

5D + 135L @2.5 ISO 100

This picture has a slightly oblique composition, but I think it works.

Sporgon your building and landscape photos are awesome - I can't imagine shooting those as JPEGs. :)

Yeah, if a beginner is shooting with a cheap point & shoot it's fine for them to use sRGB JPEGs.  But,  I thought we were talking about experienced photographers using dSLRs here. If someone is into photography and buys a nice dSLR I would never recommend shooting JPEG. There is too much loss of image detail on JPEGs.  It's like buying a nice HD1080 video camera then shooting everything at SD480. :D

Even if the user plans to only upload photos to websites it's still not necessary to limit captures to sRGB. The photo processing software like Lightroom or iPhoto is always going to automatically convert the color profile on export, no effort required from the user.

I would not recommend photographers downgrade their original captures in order to match the low grade equipment of the average web surfer or an outdated image standard. Don't aim for the lowest common denominator. Photographers should be capturing their originals in a higher quality format and only exporting a low-grade version as necessary for web use.

If we want to move beyond the old sRGB standard we need to stop adhering to that standard and start capturing and processing in a higher quality format.  :)

Thanks ! That's very kind of you . Yes I shoot all these in RAW then convert to a 16bit TIFF in Adobe RGB. ( Actually there is one that was accidentally shot on medium jpeg - The Cellarium at Fountains Abbey. I'd been taking scouting shots in unsuitable weather, just seeing where the best views were going to be, and of course I shoot these in jpeg, and forgot to change. I've overcome this now by having all B-P's stuff set up on a custom setting).

However all web based images have to be changed to sRGB. You're quite right about it being an digitally archaic colour space but there is massive inertia now because of it being a worldwide standard.

That's very misleading. Whilst it is true that colour space doesn't effect the raw capture, you always have to convert the raw file to some form where you can view it as an image, and in this viewable form colour space will apply.

However at the present time most people are just going to give themselves issues by shooting in adobe rgb due to the fact that virtually all display mediums are srgb.

sRGB was designed back in the 1990s when everyone had low quality monitors and low quality printers. Current computers and displays have much better color quality plus ICC color management and higher quality printers. So, most people are able to see images displayed in higher quality than the sRGB color gamut.

nope. unfortunately that is not the case.

most TFT displays sold today does not even reach full sRGB gamut.

the majority does not buy wide gamut displays.
they buy cheap 100-300 euro displays.

popular monitors for photographers from the last years, like the dell 2711 or 2410, have 100% sRGB and around 95-97% Adobe RGB coverage.

new TFT models, aimed at photographer, normaly offer 100% sRGB coverage these days.
but wide gamut or adobe RGB is far from being "standard".
even some more expensive models (like the samsung S27B970D) have only 96% sRGB coverage and around 69% Adobe RGB.

cheap TFT´s often cover only 87-95% of the sRGB colorspace.
the samsung S24C450MW from 2013 for example barely covers 87% of the sRGB colorspace.


as for printing i agree.
todays printer often have wider gamut for some colors then sRGB offers.

so while these printers don´t have the full Adobe RGB colorspace, it makes sense to use Adobe RGB for print.

as for my own workflow.
i shoot RAW.
i do some basic image editing in LR.
then i send the files to photoshop when they need local adjustments or further editing.
the end result is a 16bit Adobe RGB TIFF file (with layers).

my monitor is a wide gamut 10bit eizo.

but for "normal" people who are no so much into computer and image editing i recommend a full sRGB workflow. less to worry about. and you won´t notice a difference on flickr or facebook anyway. ;)

Yes, this is a detailed explanation of what I was referring to.

For Building Panoramics work, where the raison d'etre of the pictures is printing onto large canvases, I have my settings on one of the camera custom functions, and this includes Adobe RGB. The program I use to convert to 16 bit TIFF is set to carry over the camera's settings to the file. When these images are posted on the web they have to be converted to sRGB.

Unless I'm looking at serious printing I shoot everything else on sRGB now; it's a case of if you can't beat 'em, join 'em, because despite the fact that this colour space comes from the days of the digital Ark it is still the universal standard, and that is going to take some shifting.

There are many reasons why someone needs a 'high end' camera, but the availability of Adobe RGB ain't near the top of the list.

Also regarding the OP's original question on posterizatiion, using Adobe RGB isn't going to have made a half cents worth of difference in this case - in fact it could have made it worse but that's opening a whole new can of worms  ;)   ;D
