Sharpness

Looking for opinions.  How would you rate these lenses for sharpness in everyday use on m4/3?

Olympus M/Zuiko 45mm f1.8

Olympus Zuiko 50mm f2 Macro (on adapter for m/43)

Sigma 60mm f2.8

Olympus M/Zuiko 75mm f1.8

Which would you say is the sharpest?  Which the least  sharp?  P;ease stay with these four.  OTOH, which, in your opinion is the sharpest m4/3 lens in the system.

I'll post the results in a few days.

Thanks in advance.

Peace.

John

I'll go with the 75 having a slight edge over the 50, but bet they're really close. 75 bests the 45 and lacks its field curvature wide open.

Cheers,

Long term reputation in this forum has the 75mm as the best thing for sharpness. But sharpness isn't everything if the focal length does not suit the situation, so it all depends on what you are trying to shoot.

The 75mm is definitely not an "everyday use" lens, from this forum there have been quite a few users who bought it, loved the "sharpness", but found long term that they hardly used the lens so sold it again.

Using raw files plus careful conversion and sharpening techniques may help with the appearance of sharpening, but more than that, lighting the subject properly may have most effect.

Thoug I do seem to remember that the 60mm macro and 60mm sigma are pretty comparable.

The Zuiko 50/2 is all the lens that I need.

Re: Sharpness

The sigma was rated as one of the top 4 sharpest lens . The 75 held top spot but I think the sigma 35 holds the top spot now.

Re: Sharpness

On your list the sharpest is the 75mm, then the 50mm Macro, the 60mm and finally the 45mm.

That being said I have the 75mm, the 45mm and my Sharpest lens is definetly the 17mmf/1.2 Pro. I'd rate it on par with my old 150mmf/2 !

Re: Sharpness

I'd put the 50 F2 and the 75 1.8 at the top for sharpness.

Overall, the sharpest lens for m4/3 is the 300 F4 (I have all but the Sigma)

I've owned three of the four. My personal experience on sharpness is 75/1.8 > 50/2 > 45/1.8. I don't have the 60/2.8 so can't comment from first-hand experience.

I recently sold the 50/2 and the 45/1.8. Both are wonderful lens, to be sure. But the 50/2 can be frustrating due to its slow focus, and an odd flare you can get due to the concave curvature of the front lens. I intended to replace it with the 60/2.8. Even if the 60/2.8 is not quite as sharp, it was a much more 'usable' lens when I tried it out in a store. The funny thing is that the 40-150 does a surprisingly nice job of closeups as long as you don't need 1:1 macro, so haven't yet pulled the trigger on the 60/2.8. It's currently on sale for $349 so a tempting target for GAS.

The 75 is a sharp and great lens to use. But it's kind of an odd focal length ... a bit too long for routine portrait work, too short for a long lens, and the focal length covered by the 40-150/2.8.  I do use it on occasion because it is really sharp with nicer bokeh than the zoom.  But it's no longer in my 'go-bag'.

I replaced the 45/1.8 with a 45/1.2. I wanted the 45/1.2 for portrait work, and figured that I had the focal length also covered with the 12-40.2.8 zoom which meant the 45/1.8 would be redundant.

Absolutely delighted with the 45/1.2. It is in the 'go-bag' and basically replaced both the 45/1.8 and the 75/1.8 for portrait work.

Just a little bump in case others would like to comment.  This forum is so active, I had trouble finding it.

Re: Sharpness

75 > 60 > 45

Don't have the 50/2

What about Sigma 30/1.4?  It's right there with the 75.

Re: Sharpness

The unlisted Sigma 56mm 1.4 prob tops them all, except for the 50/f2.

And the 75mm is just too long for normal usages.

Very good.

No experience.

No experience.

Olympus M/Zuiko 75mm f1.8

Optically stunning.

Which would you say is the sharpest? Which the least sharp? P;ease stay with these four. OTOH, which, in your opinion is the sharpest m4/3 lens in the system.

Optically, I'd say the 75mm f/1.8 is the best lens I've ever used. I've never used lenses like the PL 200 f/2.8 or Olympus 17 f/1.2 Pro; both of which seem to get almost universally outstanding reviews for optical quality. I doubt anyone really has used enough different lenses to really speak meaningfully about comparing the sharpness of the full range of m43 lenses. And copy to copy variation could make even the most objective comparisons slightly inconsistent from test to test.

I'll post the results in a few days.

Thanks in advance.

Peace.

Re: Sharpness

Well, obviously, you don't have any interest in Panasonic lenses.  Can't help you.

Re: Sharpness

Well, Panasonic makes some very good lenses, but I have only the 20mm f1.7 and the 25mm f1.7.  I didn't include them because they wee considerably outside of the general range that I was interested in.  No slight intended.

I also have the P12-32 m4/3, the P14-42 II m/43, the P14-45 (both m/4/3,  the 14-140 m4/3, P45-150 m4/3, 45-175, and the 100-300 vi and vii m4/3.  I really did not mean to exclude them because of any lack of interest, only for manageability of the thread.  Maybe we can look at those later.

Peace.

Re: Sharpness

I use both the Olympus 45mm and the Sigma 30mm f/1.4 (not the 60mm).

Both are very sharp lenses and I love using them both.

I do not have experience with the other two lenses.
