To go mirrorless (or not)

Recently there has been the launch of the new Nikon mirrorless DSLR system, and also the new Canon EOS R mirrorless system, that gives us the opportunity to review where we’ve come and where we’re going. Obviously I have taken my own experience and camera ownership, but many of us have had a similar journey but with different marques/models.

One thing I am certain of, is that the new flagship Z7, and Canon EOS R, has much farther to go – I think there will be a significantly improved Z(?9) (or R mkII) in the near future that will be more tuned to the working pro – especially in its AF solution. If there is a weakness in the new Z7 it is in its AF interface for those myriads of experienced Nikon users, despite it being a small improvement on the Sony version. But that is another story.

Indeed, one could say that all affordable digital cameras were mirrorless for many years, but the SLR eventually won through. Mirrorless has been seen as the ‘alternative’ way – some would say is still the case.

I started with film in the 1960s. I had folding Kodak and Voigtlander folders (8 on 120 film) and often used Dad’s Yashica-Mat and Rolleiflex derived machines (12 on 120). Even today, looking in to the viewfinder of a twin lens reflex body is a wonderful experience, even if there can be left/right conundrums. I also used Russian rangefinder cameras but I wanted the lens interchangeability of an SLR.

Enter the Zenith E, then a Praktica LLC, both 42mm screw thread mounts. The LLC even had electrical contacts that gave it open aperture metering; I really wanted a Pentax ME Super but money was in short supply. I still have a Praktica BC1 – plus a bayonet mount that had adapters to mount my legacy screw thread optics.

(I still own those in bold italics)

In the 1990s the mass market produced all-in-ones with inbuilt zoom lenses, but I stuck with my SLR until digital. Expressed differently, the enthusiast/pro lines of TLR merged with the rangefinder/compacts with the new generation of digital. At this time there were all sorts of innovative shapes to cameras, though consumer expectations of what a camera should look like eventually held sway.

In 1999 I had my first digital camera – Olympus c820L – single fixed lens (approx. 35mm equivalent focal length). Auto only, but had lots of flash functions, and incredibly slow playback. LiveView seemed revolutionary. But this was obviously the way we were going, though resolution was a little low – 0.8MP, and shutter lag could be irritating (though nothing like as bad as the best selling Sony Mavica of the day).

In this millennium I have not shot a single frame on film!

Enter the Olympus c2000z – everything many mirrorless DSLRs have now. Aperture/Shutter priority, auto program, zoom 35-105mm equivalent, etc. By 2005 I had the gargantuan 5MP c5050z – all the functions I craved for in film days and much more, but still felt restricted in lens choices. I wanted to go beyond 105mm and, especially, wider. I started fitting wide extenders (from film days) that seemed gargantuan on this small body and was not entirely successful.

2005 was when Canon launched the 300D, the first time DSLRs were affordable by ordinary people, costing less than £1,000. By Christmas I was salivating for one… and the Nikon D70 launched. After handling the two there was no contest, the Nikon felt like a camera that would last decades, the Canon felt cheap plastic, and the Nikon kit lens was far better.

So now I am solidly Nikon from D70, to Fujifilm S3 Pro (used), to Nikon D7100 and now Nikon D800, and lenses that do what I expect them to do.

The Olympus digital experience hasn’t been abandoned – when I want a carry about, always available camera – I use an Olympus OMD EM5 and a few very compact lenses that all fit in a small handbag.

Mirrorless may well be the way we are going…or maybe not, if it becomes viable to merge the two into one compact body! But at present, and from experience with the OMD camera, I do seem to be fighting the sometimes wobbly technology (see other articles on this site) that is not yet solid. As an example, Olympus have released rather more firmware updates fixing glitches per camera than Nikon (10 for the EM5 vs 3 for the d800 !). The excuse that there is more high-tec in mirrorless is irrelevant until the user experience feels on a completely firm foundation.

Olympus should be praised for improving functionality of the EM-1 through firmware upgrades.

It does seem that there is a new merging of lines, the traditional established SLRs (Nikon, Canon, Pentax etc) to what we currently term mirrorless (Olympus, Sony, Panasonic, Fuji etc). Incidentally, I don’t understand why this is the tenth anniversary of mirrorless, it strikes me that Olympus have made digital ‘SLRs’ (albeit fixed lens with converter lenses such as the c1400L of 1997, or the four thirds E series from 2003) long before.

The digital chart that follows does not illustrate the importance of sensor sizes in each generation. Early digital cameras sometimes had very small sensors, but then the APS-C (DX) became prevalent, with the four thirds and now micro four thirds (MFT) joining in. Full frame was initially out of reach, but is now the sensor of choice that is capable of giving us approaching medium frame levels of resolution.

For example:

Olympus c820l:                  0.81 MP               4.8 x 3.6mm                                       4.67

Olympus c2000z:               1.9 MP                  6.4 x 4.8mm                                       6.16

Olympus c5050z:               4.9 MP                  7.11 x 5.33mm                                   12.88

Olympus OMD EM1:       16.1 MP:              17.3 x 13mm (MFT)                         7.15

Nikon d70:                           6.1 MP                  23.7 x 15.6mm (DX)                        1.65

Fujifilm s3 pro:                 6.1 MP x2            23.7 x 15.6mm                                   1.67

Nikon d7100:                      24.1 MP               23.7 x 15.6mm                                   6.59

Nikon d800:                        36.3 MP               35.9 x 24.0mm (FX)                         4.22

 

The progression as shown is thus not just in resolution in megapixels, but also in size of sensor. Pixel density is shown on the right. There are two big jumps; firstly from the small sensor sizes prevalent from the beginning od digital cameras until many of today’s compact systems; then to the popular DX or APS-C sensors of earlier and most popular DSLRs of today; and thirdly the FX (full frame) that are today’s advanced and professional cameras. Today’s d800 has a huge sensor compared to the earlier Olympus cameras, but also a lower pixel density – no wonder it performs so well!

Newer lens models are not only cheaper to produce by using moulded glass rather than cut glass, but new technologies create different trade-offs. With mirrorless mounts, the flange to sensor distance shrinks and has benefits in design, but the smaller lens bodies seem to be more prone to distortion. One might say that modern camera electronics correct this, but this at once negates the benefits of those ultra high resolution sensors.

The new Nikon Z seems to be a further trade off- a little bit smaller and a little bit more resolution, but a slight worsening of pixel density.

Conclusions from my own (brief) handling of the Nikon Z6 was that it is lighter (but only if using Z lenses, otherwise existing gear requires an adapter, negating this advantage. The viewfinder seemed very good, but migration of buttons was confusing. To express some caution, it is noteworthy that the recent Z series 50mm lens is both bigger and heavier than its predecessors… where is the gain?

In the future, we may see the demise of APS-C or MFT… or not, because they are both cheaper to produce when in a price sensitive market, and are each little brother to the up-market full frame gear whether mirrorless or otherwise.

For me, I don’t want to jump just yet. From what I have read so far, I would be very wary of changing the superb AF of current cameras to the less well developed implementation of the new Nikon Z,  even though it is said to be superior to that of Sony. There is also a need to carry more batteries and more recharging, and the presence of only one memory card socket seems to be a huge discrepancy for the semi and pro user. As I said at the start of this article, for these reasons alone I think the Z7 seems to be precursor of another pro camera that is still in the wings.

Nikon has always been innovative, and has rarely produced a product less than well made or technically sound (Nikon 1 excepted).

I am awaiting the reviews, a look and feel of the real thing, and see how it stands a few months from now.

Just to add to the proposition, my most recent shoot was at Maiden Castle near Dorchester when I used my D800 in rather poor light in dull conditions. I was confident of my photography and I did not use the rear screen to view shots at any time until I got back to base. (I have a sunshade fitted, that I left closed all the time.) On this basis I could easily go mirrorless.

But I do not have the need to change my gear yet… I think in 10 years time I might wish to carry something lighter (I will have upgraded the Olympus EM-1 by then) and will no longer aspire to selling shots. Probably. But for now, I am happy.
