This is a post about two micro four thirds camera lenses. So in 35mm film terms you need to multiply the focal length by two. Which means these lenses are a 90mm equivalent and a 150mm equivalent.
So I should start by saying that I don’t hate the Olympus 45mm lens. Far from it. It is a great lens, especially at the price. It can produce astounding results like this picture (OK, not astounding, but I liked it):
However, it can also produce shots which are good but not great (no examples this time, I fear someone will point out user error). I’ve been raving about how good the Oly 75mm is since it turned up so I decided to try a quick and dirty comparison. First, the Oly 45mm:
A nice shot, I like it, another one for comparison:
What is to complain about with these two? They look pretty decent to me. Now let’s try the 75mm:
Not much difference, right? Wrong. If you open up the examples and look at the 75 check out the detail and the bokeh on the 75mm shot. Another example from the 75:
Finally one to show that while the 75 is a great lens, it is a long focal length. This one really would have been better if I had used the 45mm to be frank:
All shot with my Olympus E-M5. By the way, the musician above is Chloe Leigh and she is another participant in the Mayor of London’s Gigs contest. You can watch her here, she is very good: http://www.molpresents.com/gigs/vote/chloeleigh
Update 22 August: Just a quick additional edit, because I noticed quite a few people from Olympus club poland linking to this site. Hello! I think one of the downsides being considered on the posts on the site was that the 75 is somehow big and uncomfortable. It absolutely isn’t. It’s certainly heavy, but not uncomfortably so (it just feels like a quality lens). I have never felt the need to use the grip with it as Robin Wong suggested in his review. I do use a half case with my E-M5, but I think I would have noticed if the lens destroyed the handling as Robin suggested.
Update 1 September: Some (mostly on DPreview, though I note one has turned up here) have queried the sharpness of the shots, in particular those with the 45 but also the shots with the 75. Having looked at them personally I didn’t think they were unrepresentative of shots I have seen on the net elsewhere, but one constructive commenter noted he had found more significant sample variation in the Oly 45 than you might expect. I had tried a couple before selecting mine, but I’ve not been able to replicate sharpness of samples others sent me in tests. Interestingly, the G5 (without IBIS) produced the sharpest results with my copy. For the sake of argument I’ve ordered a new one from Amazon for monday.
In terms of querying the 75 shots I find that ludicrous. Perhaps the first isn’t critically sharp, but the second one is a fine shot IMHO – perhaps not as excellent as some of the other shots I’ve taken with it (see the links in my comment below) but very good. As these were all default settings RAW shots processed in Aperture, I thought I would see what one of them looks like cleaned up and processed using my usual mono methodology. Make of this what you will!
Update 4 September: See https://sgoldswoblog.wordpress.com/2012/09/03/olympus-45mm/ for the results of my testing of my 45mm
