View Full Version : A question of iq

16th July 2013, 11:20 PM
i just aquired an e-pl5 single lens kit. it comes with the 14-42 II R lens. my question is do i get a 40-150 R or a 14-150 if the only question is image quality? i have no experience with micro 4/3 lenses. i already have several 4/3 lenses(9-18, 11-22, 40-150, 12-60, 50-200, 70-300) but all i read about is slow focus on m4/3. so could use the guideance of knowledgeable people.

thanks, larry

Hi Larry, I am not an M4/3 owner but was going to go OM-D E-M5. However, what stopped me was "slow focus" in that birds in flight were not well captured.

Here is a hotlink to Robin Wong and his Olympus Gear Reviews

I hope many of our experienced M4/3 users will help you, so I have replied more to "bump" your post back in the list :D

you could pm them direct ???

As a general rule the longer the zoom (10.7x for the 14-150) the more likely you are to get distortion of some sort. You're more likely to notice this at the ends of the lens rather than in the middle and it's more pronounced if you're photographing things with straight lines. That's one of the reasons why top quality zooms (12-35, 35-100 and 90-250) are around 3x or less.

That said I've got the 14-150 and it's a very good all purpose lens so long as you avoid situations where distortion is likely to become apparent. It's seldom off my EM5. I have no experience of the 40-150 but I have the Panasonic 45-200 and 100-300 which are also good, but you'll note they're both around 3-4x.

The only m4/3 lens I have is the 14-150. I't a great walk round lens, very light and fast and silent to focus on the E-M5.
It's image quality is pretty good for a x10 zoom but not as good as my ZD lenses which I use with manual focus on the OM-D.
The biggest problem it has is the amount of purple fringing(CA) it produces in certain light but this is easy to deal with in PP.

These were take with the other day.


Hope this helps

I use the 14-150mm a lot on my E-M5 - it's the one I've used most since I bought it from another forum member.

Some photos taken with it:

I have just got the same combo but will continue using my slow-to-focus 4/3 lenses until M4/3 ones are made that are of similar quality.
However, if was was supplementing my 14-42 with another longer lens it would likely be the 75-300. Although this would leave a gap in the 42 - 75 focal length range, it would not be a problem for me.

40-150 is a cracking lens and the IQ is very descent. The 14-150 is very expensive with no better IQ that the 14-42 or 40-150. I have tried all and have been pleased with the 40-150 and got used to the quirky extending tube. I admire the Panasonic mid telephoto lens because they don't extend, much neater!

just wanted to thank Chevvy for the bump(was starting to feel like and orphan, just kidding)

also want to thank David(Melaka), Andy, Roger, Dave and Glee for their input and fine examples of image quality.

now to sit down and mull it all over and look for a bargain

thanks again,

Larry, I am glad that, as a new member, your no longer disheartened :)

It is a bit busy around here at the moment and lots of valuable posts are knocked off the "New Posts" real quick - and are often gone forever, unless some of us look through "unanswered posts" *chr

It is ok to "Bump" your own post reiterating your need for information :) :cool:

No one has yet mentioned the 14-150mm as a great video lens when of course you can't stop and change lenses mid way.
