How to Choose and Use Lenses - Part 1

The best of the zooms with relatively modest ranges deliver highly impressive performance. We'll be looking at wide angles and long toms in the next columns but for now lets look at mid range options. The narrower the zoom range the better the performance. In the Canon range for example the 24-105mm f4 loses out at the wide angle end performance wise to its more modest ranged brother the 24-70mm f2.8. The latter is a lens I would never be without, endlessly useful. But then you may think the trade off in quality to get the extra range is worth it. Compromises again.

Optical performance has to be at the heart of all lens decisions. Now we can all enlarge our images up to 100% in Photoshop and analyse corner sharpness to the N'th degree. Actually I get the impression there are some in the twilight regions of the world wide web who do nothing else. It can be a bit obsessive and we have to remember that doing so is analogous to standing with our noses pressed against the margins of an exhibition-sized print. We are right to be meticulous, but at the same time we need to remember that no lens however good is quite as sharp in the corners as it is in the centre, so a sense of pragmatism is necessary. Sensor resolution had surpassed the ability of some lenses to match. There seems to be a bit of catch up going on now with new models and updated lenses being constantly announced. But it is possible to become a bit of an anorak about it all. Ultimately we need to make decisions on what to use then just get on with the business of making pictures.

The next dilemma we need to confront is the bulk of our lens. Size matters. Us landscape photographers routinely need to march over the hills and far away in search of the definitive view. Trudging up slopes with a heavy bag and tripod on the shoulder is what we do, our penance to balance the joys of being in the perfect spot at the most magical times of day. But clearly anything we can do to cut down on weight is handy. Here we have another compromise to contemplate. Fast lenses with maximum apertures of f2.8 have large front elements and are consequently bigger and heavier. The advantages of fast lenses are tempting; bright viewfinder images, differential focus effects, quick to focus, superb in low light and with fast moving action. Lenses with front elements like dinner plates are beloved by sports photographers for these very reasons. They are marvels of lens technology and a joy to use, if you don't have to cart them far. Let's face it most sports photographers only have to walk from the car park to the touchline. (I guess that sweeping statement may generate a few e-mails!) But for us mortals reliant on foot power we have to ask is the speed worth the extra weight?

And there is another major downside; fast lenses cost a fortune. Solely for landscape work it would seem fast expensive heavy lenses are counterproductive. But the annoying thing is to just muddy the waters further; fast lenses tend to be optically better then slower ones. And once you've used a fast lens there's no going back, they are addictive. Nothings ever simple, is it? I use f2.8 or faster lenses throughout my range. I just have to live with the weight on my back. And in a dark crowded Marrakesh souk the advantages of a fast lens become immediately apparent as I drop the background pleasingly out of focus. At least in the mid range focal lengths we're talking about this month fast lenses aren't too mammoth. Predictably my 24-70mm f2.8 is my most used lens. For landscapes, reportage, portraits, whatever, I can't imagine a single use that this lens wouldn't be handy for. Longer or wider lenses may be sexier but few have earned their keep as this one has. Nikon, Canon and all the independents make their own variants of this ubiquitous zoom.

The mid range lens choice should be the first and arguably most important acquisition. Get it right and the other options both longer and wider will fall into place. A mid range zoom is an obvious starting point, but there are alternatives that are more compact and faster; standard primes. The trusty 50mm lens that used to come as standard with all SLRs is obviously not as flexible as a zoom but is lighter, optically superb and affordable. The angle of view and perspective of a standard lens gives a pleasing, natural balance between foregrounds and backgrounds. The bog standard variants of these lenses are also fast, typically f1.8, and super fast variants up to an incredible f1.2 maximum aperture are available. Use a lens this fast for the first time in a market in Bolivia and life will never be the same again. I have a slightly longer then standard 85mm f1.2 piece of glass. For intimate portraits with a sense of place in crowded and bustling environments there's no optic like it. The super fast aperture delivers outstanding low light options and differential focus effects, but at a price; size, and cost. For its focal length it's a bulky beast and the F1.2 aperture increases the Bad News to six times the price of its f1.8 brother. Worth it? It's all about compromises.

Clearly portability, convenience, performance, flexibility and size are all factors to consider along with the crucial optical quality. So too is build quality and the bottom line, price. Generally the old adage that you get what you paid for is true in the photographic world, although with the wealth of information and test reviews we now have available to us on the internet there's no need to take that as read. The big question is do you go for camera brands or independents? Significant savings can be made by going for lenses made by Sigma, Tokina or Tamron over the likes of Canon or Nikon. And it would be wrong to think that the performance of the independent's optics is inferior; in some cases they're superior. I am however going to stick my neck out here and assert that generally the build quality of the Big Boys is more rugged then the independents. The fact that most pros use Canon or Nikon pro spec lenses says it all. How important to you is that? My gear has a hard life, in out of planes, lashed by wind, sand, snow and rain, up mountains and bouncing around in the back of 4x4s. Say no more. But no pro is impervious to the cost of equipment. If it's not earning its keep, it goes. Generally the way I look at it now is that the money I used to spend on film and processing every year now goes into continually updating my system with replacements and additions. I now only use one system so all the available resources can go into ensuring that it is a comprehensive and flexible system. I am continually blown away with the quality available from the 21 MP full frame sensor cameras like the Canon 5D mkII and 1Ds mkIII, but to get the very best results impeccable technique and optical quality is crucial. So if you are contemplating acquiring some new glass your options are clear. Cash in on your bodily organs, auction your parents on ebay, pawn your lady's jewellery or flog your bloke's car and sell off the kids for medical experiments; just make sure you get the best lens you can.

Next month we'll be looking at long lenses and considering some of the specific dilemmas presented when choosing them. I'll also be examining how to make the most of these long toms and what pitfalls they present when using them in the field. And the following month is all going to be about wide angles. It's a real lens feast.

Biography

Born in England in 1957, David spent much of his youth travelling with his family between the UK, California and Canada. After leaving school David joined the Navy in search of further travels and adventures – and it was while sailing the seven seas that his interest in photography grew. After several years at sea he decided to pursue his passion for photography and returned to study in Gloucester, England.  After leaving college in 1985 he began work as a freelance photographer specialising in landscape and other travel subjects, which over the last 25 years, have taken him to almost every corner of the globe.

David is now established and recognised as one of the UK's leading landscape and travel photographers. His images sell all over the world – both as fine art photography and commercially in advertising and publishing. He has won international awards for: British Gas/ BBC Wildlife Photographer of the Year Awards in 1985,1989 & 1990 and also writes regularly about landscape and travel photography for a number of national and international magazines. David has worked for numerous clients including British Airways, Sainsbury's, Geo, Toyota, Qantas, Sunday Times and the Telegraph.  During the last twenty years he has also worked extensively for the National Trust covering much of the UK's landscape and coastline, which has featured in many high profile publications and several highly acclaimed photographic exhibitions. Most notably:

'New Vision' Contemporary Art Photography – AOP Gallery
'The Coast Exposed' – Maritime Museum Greenwich and the Lowry
'Climate Change – in Britain's Back Yard!' – London, Nottingham, Wales, Belfast, Bristol

“l'm still passionate about photography. All aspects fascinate me; from capturing the first light of day on a frosty landscape or making the most of a bustling market in Vietnam to portraying the dignity of a wrinkled face in China.”

David spends much of the year travelling with his wife Wendy. When not travelling they live in England, near Sherborne in Dorset.

#2 Sony Cyber-shot DSC-W290 Review

we can take the photo lets start with say a 16mm to 500mm zoom then Now the evolution of 20+ megapixel sensors has put the spotlight back on this debate , Barrel distortion, flare, soft corners, unsharpness to name a few; all these nasties creep in when all is not right optically. Of course, this is all relative.

There is no dearth of the type of outdoor photography you can aspire to choosing to do when out in the wilds: the range of natural, wildlife photography covers the varied purposes of professional photographers and even hobby photographers keen to commit to film and memory their tryst with the wild side of nature e.g. animals in their natural habitat.

Was looking at David Noton’s website and he’s spparently running an evening roadshow in Sheffield on 25 February - might be of interest for anyone in the middle of the UK.

This article came at the most opportune time for me.  It makes so much sense to me now on the right choice of lenses to use or to buy next. Thanks.

I’m delighted to discover that I (as a beginner) think the same way as heavy artillery like Mr Noton does. I also fall in love with the 24-70 f2.8 (and the 70-200 f2.8). Now I can’t see myself go shooting without them !
  Like all Mr. Noton’s articles, this one also helps a lot ! Thank you !

Like David I have found that compromise was the practical way for me. Our family have considerable Nikon equipment, and I stuck with that for lens changability. However the Australian outback dust beat me. After umteen lens changes before breakfast the dust would be all over the blue skies. Last year after a pro. cleaning of the digital sensor, I fitted a Tamron 18-270 VC and used it without changing from March 09 till now, and the flexibility over thousands of photos has worked out well, and there are currently only about five significant dust spots annoying me. As a “walk around” lens it is a good compromise. I am enjoying your article David, Thank You!

The article is great. Choosing a lens that you need for is always a real problem. The author is absolutely right: this issue is all about compromises. However, as many I believe, I often cannot curb appetite for having a new one that may never see the light of day.
Kind regards, Alexander, Moscow.
