'Giving life to old and new manual lenses'.


With notes on lens adapters and macro close up lenses.

Introduction.

There is no doubt the convenience on many occasions, both in the macro world and landscape, of modern auto focus lenses which are often fitted as cheap kit lenses and more expensively as stand alone options from manufacturers to many a modern digital camera. However lurking in a dark corner, perhaps unloved for years from film days there may be new life for older manual focus lenses from a bygone era. Besides bringing them back to life their build quality and finish outshine by a good margin many a plastic lens not only of the 'kit 'variety but expensive macro and zoom lenses now provided by the big manufacturers and with a little patience can give rewarding results not only in the pleasure of handling and using them but in their optical performance too.

With the arrival of the Panasonic G, GF and Sony NEX series of inter-changeable lens cameras, which have very short sensor to lens flange distances, it wasn't long before a whole raft of adapters were being manufactured by the Chinese available for the micro 4/3, 4/3 and Sony mounts. So as well as modern plastic auto focus lenses for these bodies it also became possible to fit older lenses from the likes of Leitz, Leica, Zeiss [Contax] and Nikon as well as being able to fit new manual lenses from Leica, Zeiss, Voigtlander etc. This has resurrected the use of much older lenses with pleasing results. From over 30 years ago my brother Dave has kept his old Nikon AI lenses then of course being used with likes of the Nikon Nikkormat 35mm film body and for a small outlay experiment with these fitted to the likes of Sony and Panasonic camera bodies.



Typical adapters for the Sony NEX and Panasonic micro 4/3.

Leica M to Sony NEX, Leica M to micro 4/3 & Nikon to micro 4/3 lens adapters.

In general the quality of these adapters are admirable for their price, a typical adapter bought direct from Hong Kong on eBay will vary between 10 to 20 including shipping. However it is worth shopping around from the dealers for the best built as several designs of the same type can be available, also considering your budget for how much you wish to spend. You will also find the same adapters being sold in the UK with high mark-ups of typically 2 to 3x the Hong Kong price were the eBay seller will be buying in bulk and making a healthy profit relying on the fact that some people prefer to buy from a UK based seller. My brother Dave and I buy ours direct from Hong Kong, the low prices don't attract customs duties and usually arrive in small 'Jiffy' bags in around a week or less. There is a small advantage buying from a UK seller however in that it is more convenient to send back the adapter if you are not happy with the build. Feedback from us sent to Hong Kong suppliers has been positive when we have had an issue with the design in some way in that they seem very interested on user satisfaction.

In the above picture on the left the first adapter is the Leica M mount to Sony NEX this is well made and both the lens body to adapter and adapter to camera body are a smooth and snug fit when fitting. The only part I don't like is the small 'pin' that requires depressing to remove the lens it is rather fiddly.

In the centre The Leica M to micro 4/3 adapter, this has a larger more convenient tab to release the lens but a slight wobble of the lens when fitted spoils the overall impression of a well made unit, this information was passed back to the suppliers in Hong Kong.

On the right is the Nikon AI to micro 4/3 adapter. This is a very well made unit, both fit and finish are superb and provide a rugged interface for the Nikon E series I have used with the Panasonic GF2. The aesthetics are most pleasing and make a beautiful combination with the lenses fitted to the camera.




Panasonic GF2 fitted with Nikon AI to micro 4/3 adapter with Nikon E Series 50mm f1.8 lens, a lovely package and well balanced in the hand.

The 52mm filter thread used throughout most of the old Nikon AI lenses means everything is kept simple for polarizers, close up lenses etc, compare this to new lenses with wide variations in filter thread between different lenses from the same maker.

Anybody who has used modern plastic auto focus lenses and adjusted the zoom [which often projects further than you think], grinds as you turn the friction plastic on plastic moldings.. well what a refreshing change to use one of the old lenses like these, ultra smooth focus, f stops that click with precision makes you feel are back once more in the world of a bygone age when things were done right. The E series lenses by Nikon were a cheaper and simpler alternative to their full price versions but this provided a lighter more compact body ideally suited to modern small camera bodies like the Panasonic GF2.



Comparison in lens sizes.

Above and below, the older design of the Kood close up lenses with no coatings to the glass reduces contrast and adds softness to the image but with the right subject can add an ethereal feel to the picture.

On buying second hand manual focus lenses.

Remember the focal lengths of these lenses will be a lot different to their marked values so ton he Sony NEX for instance a Nikon 50mm standard lens will become 100mm so this will be have to be taken into account when shopping around and how much patience you have in the field if you wish to use without a tripod as subjects with close up lenses attached can appear to move rather alarmingly on the LCD monitor. However in my own case since one of my main interests is shallow depth of field close up work with the 'dreamy' backgrounds these fast lenses provide at full aperture together with an effective longer focal length are ideal for best effect.

Contax G.

With the Chinese providing the methods for fitting older lenses the markets have changed somewhat regarding pricing of lenses. Take for example the Contax G series made by Zeiss that were used with their compact G1 and G2 35mm automatic film camera. These lenses are quite modest looking affairs more often than not finished in an anodized silver with occasional black versions being found. Some years ago before the rise of the adapter market these lenses could be found cheaply both in the back pages of dealers in magazines such as Amateur Photographer in the UK and of course eBay sellers but now their renowned excellent optical quality and being able to fit to cameras like these have made them scarcer to find and pushed prices higher.

The adapter needed to fit these G series lenses have a special focus ring, this activates a revolving toothed pin that fits into the flange of the lens as the lenses themselves have no focus ring. At one point I was considering buying a Contax 45mm f2 lens so had purchased the adapter but the rising prices of the lenses and often the lack of original lens caps, documentation and boxes put me off. The adapter I received was rather crude from China, the focus ring was grinding and lumpy but fortunately after dismantling, cleaning of the sticky and patchily applied grease from the manufacturer and using Nye grease the action was much improved but sold the adapter on without buying the lens.

Leica M.

Leica lenses are not usually found cheaply! However the older Leitz lenses from the 1960's can sometimes be found at 'acceptable' prices if you are in the market for the brand. I have not owned any Leica or Leitz lenses but the style and finish certainly seem to vary quite a lot especially on the much older lenses, many reviews are available on the Internet and some with regard to compatibility with modern digital camera bodies like the Panasonic and Sony.



Voigtlander 35mm f2.5 Color-Skopar with Leica M mount fitted to the GF2.

I bought this Voigtlander lens because of its build and compactness together with excellent technical reviews, very little in the way of distortion can be seen when photographing objects with straight edges in terms of barrel or pin cushion, I can't say the same for a number of kit lenses at the same focal length over the years. It works with Swiss watch precision and the 10 blade diaphragm provides an excellent bokeh (i.e. the 'look' of out of focus backgrounds). Japanese built it has the same feel and presentation as modern Zeiss Contax lenses. It uses a 35mm filter thread so a large step up ring is needed to use my B+W 52mm macro lenses but these are very cheap and for me cost effective rather than buying 35mm close up lenses, it does add weight however.

Nikon AI.

Both the Nikon E series and the more expensive AI equivalents can be found at more modest prices second hand, a huge range is available many of which stick to the 52 mm filter thread. A lot of the primes and semi wide angle are fast lenses, f1.4, f1.8, f2.8 are typical, this extra aperture can be useful in some circumstances in terms of technique or keeping the shutter speed up in dim light. The ones I have come across are all well made and finished and in those days each lens came with the Nikon quality check sticker, something you don't see these days!

Close up lenses.




Kood, B+W & Nikon achromatic doublet 4T close up lenses, all 52mm thread.

The above picture shows a collection of close up lenses which may be attached either direct to lenses like the Nikon in this article or via step up adapter ring which was required for the Voigtander lens which are available for a few pounds on eBay. The Kood uncoated collection was bought as a set many years ago, my favourite are the B+W which are solid brass construction and coated glass. The Nikon achromatic doublet has better colour correction which is great for removing any signs of colour disturbance specially around tips and edges of flowers and plant leaves in high contrast situations like shooting towards the sun. The downside is the doublet is heavy and can unbalance an otherwise 'good feel' with lens and camera.
When fitting two close up lenses together the stronger of the two denoted by the higher number is fitted first. Stacking up to a point is acceptable but with uncoated lenses like the Kood more reflections are introduced. The combination of what otherwise are lenses which can only focus down to 0.7 metres like many of the old standard 50mm lenses with close up lenses fitted transforms them into macro lenses. Going one step further the same Nikon lenses for instance can be reversed with the correct adapter but without the close up lens attached transforms them into 'super macro' but working distances are now much smaller and a tripod with fine focus block or copy stand is required ideally. So the versatility of these older lenses is impressive if you like taking macro shots!

The above macro routes are very cost effective if older lenses to add macro adaptors are owned. The dedicated modern macro lenses for the Panasonic and Sony cameras, especially the former are high, although the benefit of autofocus and metering at full aperture is of course gained.

Technique.

Everybody has their own likes and dislikes when it comes to technique, as far as my own preferences are concerned for macro using older manual focus lenses I decide how much area I wish to cover and select an appropriate lens and close up lens combo, then either set the lens focus ring to infinity or to the closest focus distance, this will vary by a considerable degree the captured area, I don't try and focus the subject using the focus ring on the lens but use my arms and body to adjust my position for the point of focus. This is due to the fact I do not like using tripods, if you wish to use one then a different technique can be used. If a tripod is used you can use the 'manual focus assist' which is both on the Sony and Panasonic cameras by a push of a button which magnifies the subject several times [7 or 14x on the Sony] which aids focus greatly, trying to use this feature hand holding the camera and you will make yourself dizzy unless you can hold the camera as steady as possible!

With wide apertures used for my macro's shutter speeds are around 1/500th to 1/2000th of a second on a sunny day with ISO selected in the region of 200, as I move from sun to shade large variations of light available can occur and the ISO increased accordingly, with modern cameras like the Sony 800-1600 ASA can be used and I like the fine grain effect it provides at the higher end. As the focal length is increased considerably with the use of these lenses on both the Panasonic and Sony a careful choice is essential if it is not to become unwieldy if hand held shots are to be taken as subjects are going to move wildly about on the monitor, a tripod is desirable for these. The Voigtlander works well as it is small and light and becomes a 70mm lens and the 50mm Nikon standard lens is also suitable. Macro lenses of old for film cameras had focal lengths typically in the region of 90-100mm.

Although the Panasonic 4/3 system uses a smaller sensor size than the Sony APS [also used in many DSLR's] noise or 'artifacts' have not been a problem in the  delicate shading, deep colours and highlights of the pictures I have taken, at least in the final sizes I prefer.

Conclusion.

Nobody can deny the convenience of auto focus lenses and of course the light weight kit lens attached to the Panasonic GF2 has a 52mm filter thread so the same close up lenses may be attached with the versatlity of zoom thrown in. However sometimes the extra difficulty but use of finely engineered products like the Nikon E series lenses which would otherwise perhaps have sat in a drawer can take on a new life.. for little extra expense we can once more enjoy the days when all photography was based around the user considering in deeper thought about shutter speeds, f stops, ISO, etc and the way these effect the final photographic result, no bad thing in the modern world of autonomy.

Both the Sony NEX-3 and Panasonic GF2 are excellent cameras, the Panasonic has great build and finish but the Sony is not far behind albeit of plastic construction. The high resolution articulating screen has the edge over Panasonic's fixed lower resolution screen which I found to be a bit duller outside but both provide excellent images and the menu structure on both is not too complex, I have seen complaints on the web about the Sony interface being slower to access some settings but I personally think it's a breath of fresh air and highly intuitive compared to a number of cameras I have had opportunity to use in the past.

Thanks to my brother Dave for the loan of the Panasonic GF2, Nikon lenses and close up lenses for this article.
