The bad news is that the Olympus M.Zuiko 40-150mm 1:4-5.6 is a plasticky telephoto zoom with OK, but not spectacular performance.The 5.6 maximum aperture on the long end is quite slow.
The good new is that it can often be bought for a paltry $150US while offering a 80-300 mm full frame angle of view. It is also both extremely small and light.
So, over and above the low price, why should one consider 40-150mm 1:4-5.6?
Reason (1): It is not all that bad
In fact, below 100mm, it is actually decently sharp. The photo below (featured in my freely downloadable book “Pictures of People“) is a pretty good example of what can be done with this lens. It absolutely looks fine in an 8X10 print.
If you go in and pixel peep, you will surely find it less sharp than better (more expensive) lenses. But, if you saw it printed to 8X10 I seriously doubt you would think it come from something less than $200.
If you need more convincing:
- Check out the surprisingly good photos in Robin Wong’s review.
- This test at photozone.de notes ” it does a decent job in terms of resolution” up to about 100mm. At 150mm, it is “somewhat more reduced”.
- A favourable review at lessgearmorephotos.com.
Reason 2: It is unobtrusive, compact and light
At 190g and 8.31cm long it is an ideal travelling companion. You won’t even know it’s there! The importance of this cannot be underestimated when on the road. I feel sorry for people lugging around big monster full frame lenses and mega back packs to tote their gear. I have a small bag, and never go around with more than two lenses.
Reason 3: Finding to your focal lengths without breaking the bank
Though few photographers are truly polyvoant in their ability to make decent pictures with a wide range of focal lengths, I truly believe that most people will actually “gravitate” to a small range. I am a telephoto person and can’t make a decent photo with a wide angle lens to save my life. The question is – how do you find your focal length sweet spot and select the corresponding lenses without breaking the bank? You can start off with two ‘kit’ zooms, such as the m43 14-42mm and this 40-150mm lens and take lots of pictures. Put them in lightroom and rate the ones you like best. Then, using at your highly rated, look at the frequency of focal lenghs used. Once you understand this, you are in a position to buy the top notch, super sharp lens to match your style. If, for example, you find you use the 40-150mm 1:4/5.6 a lot, particularly beyond 100mm then the 40-150mm 2.8 could be a wise choice. If, on the other hand, you find a lot of usage between from wide angle up to 100mm, then perhaps the new Olympus 12-100mm 1:4 pro lens and a fast prime would be the only two lenses you really need. In this context, the inexpensive zooms like the 40-150mm 1:4.0/5.6 are tools to help you define those one or two high quality lenses you really need (verses buying them all).
How much do I use mine?
Right now, to be honest, not much. I used my 40-150mm 1:4/5.6 a lot when I first got it. But, following my own advince in “reason 3” I ended up purchasing an Olympus 45mm 1.8 and 75mm 1.8. I use these two lenses 75% of the time. It still use the 40-150mm, but mostly for those rare occasions when I need to go beyond 100mm. That being said, I don’t plan on selling it as it is still somewhat useful and still very fun to use!
Why buy? I view cheap lenses as discover tools that help you identify the one or two ‘expensive’ lenses that are best for the photographer. In this context, if you getting into photography I highly recommend starting with a lens like this. Being extremely compact while offering a decent magnification range makes it attractive for travel. Plus, it will not break the bank!
That all being said, lenses like the Olympus 75mm 1.8 are in a totally different league. Plus, more expensive lenses tend to be faster. So, once you are aware of your focal lenghs of preference, I would invest in the more expensive counterparts.
