So after the other announcements, it was time for Nikon.  Most the announcements did not interest me but the additional version of the D810 did interest me.

Whilst I have no intention of buying the camera its nice to see a niche like astrophotography being filled with a camera as good as this.

Apart from changes to shutter speed range the big change is in the filtration to allow infrared light to be recorded.

Its seems we have had a bit of pause in the megapixel race, the high end cameras have not moved much.

Now we have the the new Canon and I think its time to remind people that with an increase in megapixels comes and increase in issues you have to overcome in getting good quality images.

A modern 16 megapixel, micro four thirds or DX sensor gives very good image quality, but if you want to print big then the more megapixels the better.  There is a reason why fashion photographers and landscape photographers who want to fill an advertising hoarding use medium format.

But cameras like the Nikon D800, the Sony A7R and now the new Canon 5Ds can get close to this kind of quality, at least for resolution if not dynamic range.

The issue with cameras with such high resolution is that your lens and technique has to be flawless.  Nikon produce a list of recommended lens, a consumer kit lens is not going to cut it.  Along with the best glass, you need a quality tripod, cable release, and mirror lockup.

So if your going to print big and have the patience to use correct technique high megapixels cameras can produce stunning images but for most of us, its over kill and you are likely to end up with worse looking images.

This week saw new cameras announced from both Canon and Olympus.

In the high megapixel race Canon and Nikon have been playing leap frog for many years.  After many years of Canon leading the race, since the Nikon D3x and the D800 range, Nikon have been top of the high megapixel race for Digital SLR’s.  Now Canon take the lead again with the new Canon 5Ds at 50 MP its knocking on the door of medium format for resolution if not dynamic range.

For me though the more interesting camera released this week is the new Olympus OM-D E-M5 Mark II Digital Camera Body.

Hasselblad have a shift mode in some of there cameras allowing you to get better resolution with less megapixels.  The new Olympus can do the same trick, so while on paper a very good 16 MP micro four thirds sensor, it can when shooting a static subject and on a tripod rival a cameras of 40 MP or more.

The old model was great camera, but the build quality compared to the OM-D E-M1 and E-M10 was not in the same league, I expect this to be close to the great M1.

Nikon announce service advisory for original 10-30mm series 1 lens.  Check out the details here.

Issue
When the 1 NIKKOR VR 10-30mm f/3.5-5.6 lens is used for an extended period of time, or zoom operations are frequently repeated, proper communication with the camera may not occur, which may cause an error message to be displayed in the camera monitor, and the lens may not function properly.

As in the report above, I keep seeing people saying that mirrorlesss will take over in the next year.  At some point this will be true but its going to be Canon and Nikon that drive this I suspect.

I get asked by a few budding amateur photographers quite regularly what camera they should buy, and they are only interested in the SLR options as thats what they think a ‘professional’ uses.  To be honest when you can pick up a new Canon or Nikon with a kit zoom to start you off for £350, its hard to justify them spending £500 – £1500 on a mirrorless solution.

It used to be that a RAW file was just that, the raw data from the sensor, which you imported into your favourite RAW processor and dealt with as you saw fit.

Today a RAW file is not always quite what it seems.  Many cameras now do a degree of processing to the raw data pipeline.

Most cameras do a degree of noise reduction, something I dislike as third party programs are generally much better.  Most Canon and Nikon DSLR cameras can have this turned off in the settings, but some do not act quite as you expect.  I have a love and hate relationship with the Nikon V1, if you turn off the noise reduction it does just that, except if you have the ISO set above 400 ISO, go any higher and it turns on even if you have it set off!

The Fuji X Trans Sensor is another good example of a ‘difficult RAW file’.  As I mentioned the other day Adobe and the other big RAW processing companies have now got a handle on it but to begin with you were better off shooting jpg, the greens were very difficult to get right.

Then we have the subject of in camera correction.  Its much easier now to build a lens with some distortion and correct in software, engineer the lens to correct issues that are difficult to correct in software and for things that are simple to correct in software, allow the lens to distort in a controlled way.  This gives us cheaper smaller lens that produce excellent image quality.  Some purists hate this but more and more camera manufactures are going this way.

One other setting you can find on cameras is compression settings, many cameras have three options for saving RAW files, uncompressed, loss-less compressed and lossy compressed, but a few do not give you the option.  The biggest culprit of this is Sony, their highend cameras shoot in 14 bit but then save the raw file as a lossy 11 bit file, it does not give you the option.  If you get the shot right in camera then no problem but if its slightly off or if you intended to do extensive post production in photoshop then you would be better off with another camera that gives you all your bits.

So in answer to the question; no not all RAW files are the same.

 

I finally booked my tickets this weekend for the big Photography show of 2015 in the UK. Yes its time for the Photography Show at the NEC.

Last year I bought my new printer there, getting a really good deal, this year I am looking at scanners.

The big thing for me is that Leica will be there.  I am looking forward to getting my hands on the Leica T, the new X3 and of course comparing the Leica ME with the Leica M 240.  I have a Leica M8 and would love a newer version.  I can afford the ME but the M 240 is a bit of a push so it will be nice to see how much an improvement over the M8 they are and if I would be happy with an ME or need to keep saving for the M 240.

Its also going to be interesting comparing the Leica T and X3 with the Fuji X100T. I feel the Leica will have the edge on image quality but with the viewfinder the X100T may just top it.  The big advantage of the T is I can use my current Leica glass.
