I recently wrote about an adapter I bought for my 5D which allowed me to mount my old Olympus OM Zuiko lenses on it. In that post, I provided a couple of samples with a normal range 55mm f/1.2. Here’s a quick update with a longer lens – the Olympus OM Zuiko 135mm f/2.8, with a particular emphasis with how it performs with a Canon 5D Mark II.

I’m a big fan of the old Olympus Zuiko lenses which have a few interesting characteristics:

1. They are very compact
2. They can be cheap second hand (compared to many other brands e.g. Leica, modern lenses, etc)
3. They have great out of focus characteristics (with beautiful, creamy Bokeh)
4. Many have very close minimum focusing distance
5. Optically, they’ve very impressive

I’ll give a quick overview of each of these characteristics with respect to the 135mm f/2.8

Compact / Size

The 135mm f/2.8 measures a relatively small 3,2″ (80mm) max length x 2.4″ (61mm) max diameter. Given it’s all metal / glass construction it weighs 0.8lbs (360g) which while light, is enough to make it feel solid and hefty for its size. A clever feature is that it contains a built in hood which can slide out / retract easily whenever you need it. The shape of the lens itself is cylindrical and doesn’t enlarge as you move away from the base towards the lens. This makes it very portable  – I am often able to carry it in a jacket pocket for example without much fuss.

To provide some perspective, the faster AF Canon L 135mm f2 is approx 112 mm (4.4 inches) max length x 83mm (3.2 inches) max width. Weight is 1.7lbs (750  grams). While these dimensions reflect some of the difference, in the real world, it’s even greater. Pointing the Canon 135mm L at people in the street (particularly when the hood is attached) is an easy way to get noticed. Although not entirely inconspicuous, the Olympus OM Zuiko 135mm f/2.8 is not as obvious.

One downside here is that while the build quality of the lens is superb, on my Zuiko -> EOS mount, it doesn’t feel as rigid or secure as some other lenses. I suspect it’s my adapter at fault here. While it doesn’t affect anything in terms of image quality / safety / performance, it is noticeable. My only other criticism is that when mounted to a 5D, it looks… well, kinda ugly.

Price

I love this – I bought my Olympus OM Zuiko 135mm f/2.8 lens for $99 on ebay for a buy it now. I’d consider the quality to be somewhere between Excellent and Mint. There aren’t hundreds for sale on ebay but wait and a while and it’s pretty easy to pick one up. In contrast, the superb Canon 135mm f/2 L goes for a grand on Amazon (and this is the best value L lens). Alternatively a Canon 135mm f/2.8 with soft focus will still set you back nearly $500.

Bokeh

The bokeh of the Olympus OM Zuiko 135mm f/2.8, like many Zuiko’s, is gorgeous. When there are elements of the image that are very out-of-focus, it takes on that swirly effect – but it’s not as apparent as in some of the shorter focal lengths. Here’s a shot when mounted onto a Olympus OM-1 film camera which illustrates that effect:

With more typical scenes, it’s what you’d expect from a high quality lens – a beautiful, smooth, drop off in depth of field which gives pleasing subject isolation. It’s not as a dramatic effect as with an F2 at this focal length, but it still looks great. Here’s a shot from this afternoon that illustrates this:

Minimum Focusing Distance

A lot of the Zuiko’s have impressive minimum focusing distances. Not so with the 135mm f/2.8 which actually has a fairly long min focusing distance of 1.5m (nearly 5 feet). What does this mean in real terms? Well, head shot portraits are fine but you can’t get a lot closer and you certainly don’t get any macro effect. Here’s an example of what a min focusing distance gets you with a portrait (shot on a Olympus OM-4 film camera):

Optics

I’ll be honest, I wasn’t expecting that much when I bought this lens originally. I just figured I’d get something cheap, fairly portable and would be useful in a pinch for the film work I’ve been doing. However, after shooting with it for a while, this little telephoto is turning out to be quite a performer with excellent sharpness, great colour and as I mentioned already, wonderful out of focus characteristics. For resolution freaks, here’s a couple of examples with 100% crops which show the resolving power when mounted to a Canon 5D Mark II:

Canon 5D Mark II + Olympus OM Zuiko 135mm f/2.8 (original image)

Canon 5D Mark II + Olympus OM Zuiko 135mm f/2.8 (100% crop)

If you click on the 100% crop, you’ll see what is actually extremely impressive sharpness at the center. I will add that this was shot wide open at f2.8 and I’ve done no photoshop to the original or cropped image – it was already way sharp enough. Pretty cool. You can see a little vignetting but nothing particularly concerning.

Now, if staring at lines one pixel in width doesn’t do it for you – here’s a shot of the same scene but taken at a time and with lighting that actually produces a real image:

This version was taken at 7am on a beautiful morning. Shot with an Olympus OM-4 + Olympus OM Zuiko 135mm f/2.8 on Fujichrome Velvia 100

Coming back to pixel peeping for a moment, here’s another example:

Canon 5D Mark II + Olympus OM Zuiko 135mm f/2.8 (original image)

Canon 5D Mark II + Olympus OM Zuiko 135mm f/2.8 (100% crop)

This one I’ve applied a minor unsharp mask to. It suffers a little from relying on my manual focusing skills which can be subject to minor misses once in a while. Again though – looks v good.

If 100% crops doesn’t get you going, here are a few real images. I shot these this afternoon in the space of an hour or so while wandering around. Again, all when mounted to a Canon 5D Mark II:

Verdict

I normally don’t get too excited about a lens with a maximum aperture smaller than f2, but this little old telephoto has definitely impressed me. After all – what’s not to like. Lets summarise… It’s a small compact telephoto that produces ultra sharp images with beautiful out of focus and a max aperture of f/2.8. It can be used on the legendary Olympus OM line or mounted to Canon’s EOS sytem for a cheap adapter available on ebay. An excellent to mint copy costs a hundred bucks (cheaper than the cheapest plastic lens Canon makes or about the same as a month of latte’s).

Again, seriously, what’s not to like.
