Re: Rank Oly lenses in terms of sharpness

The Olympus 12mm and the Panasonic Leica 25mm should be in there somewhere as well and then you have the manual primes from Voightlander.

Re: Rank Oly lenses in terms of sharpness

According to DXO:

1. Olympus 75mm 1.8 is top

2. Then equal second is the pan leica 25mm and panasonic 20mm

3. olympus 12mm f2, 60mm macro, sigma 60mm f2.8 and panasonic 35-100 f2.8 zoom

4. olympus 45mm 1.8, oly 12-40 f2.8, pan 12-35 f2.8, pan 7-14 f4

These were all tested on the EM1,

The new pan leica 42.5 f1.2 and 15mm f1.7 have also been tested but not on the EM1. They were tested on the EM5.

The 42.5 is sharper than the olympus 75mm 13mpx over 12mpx.

The 15mm has the same sharpness as the pan leica 25 and panasonic 20mm.

These are just sharpness results.

Edit: sorry just read your title again and you wanted just Oly lenses. Not sure why but I suppose you can filter out the other lenses mentioned.

That’s interesting. Though I’m not as obsessed with “sharpness” like so many here seem to be I’m surprised that the 12mm prime is considered sharper than the 12-40mm given the fawning praise (possibly worthy) that this lens has produced from so many.

The 42.5 1.2 has been but rates as 12mpix on the EM-1 Vs 13mp on the EM-5....same with the 75. they have most lenses as being a shade sharper on the EM-5 than the EM-1.

The 42.5 is sharper than the olympus 75mm 13mpx over 12mpx.

Depending on the camera....the 75 scores badly on the GX7 (only 7 Mpix)...many think the GX7 results have had something go wrong though.

The 15mm has the same sharpness as the pan leica 25 and panasonic 20mm.

These are just sharpness results.

Sharpness is very much lens AND camera dependant for DXOmark.

For instance the FF A7 kit lens rates 22Mpix on the A7R but only 15Mpix on the APSC cameras tested on.....obviously the larger sensor size plays a big part in the scores.....the A7 kit lens IS a nice lens but no one would argue it is better than the Oly 75 1.8 on any 16mp m4/3 camera.

A lot of people sing the praises of the 12-40 mostly because it's still new and shiny.

The 12-40 F/2.8 gets a lot of praise because it covers so much territory... 24-80mm and is still sharp and reasonably fast without many of the typical flaws you see in a zoom compared to a prime. For those who already have the 12-40 it's hard for them to justify why they need the 12 as its a lens that is already covered by their zoom which is understandable.

On the other hand, for someone like myself who already had the 14-42 II R it goes the other way, I find it hard to justify why I should spend $1000 to justify a lens that I already have, so I bought the 12-2 and will probably buy either the 7-14 or 40-150 next. For me it's about justifying what little spending money I have to get the most out of my kit and in that sense the 12-40 doesn't justify itself as anything more than a lens dupe.

Re: In my experience...

1. 75/1.8

2. 60 macro, 25/1.8

3. 45/1.8, 12/2

4. 17/1.8

5. 17/2.8

I don't own the 12-40, but have a copy of the 12-60 which is apparently quite similar in terms of sharpness. I would place it in group 3.

One thing to note: sharpness is not the most important attribute of a lens. Micro contrast is in my opinion more meaningful to the life-like rendering of a scene. In this respect the 12/2 does very well, followed by the 25/1.8 and the 17/1.8.

I would sing its praises in the future when it is old and hairy. It's a good lens. For me it has totally removed any vestiges of prime lust.

For people chasing sharpness, the tests appear to show that the 12-40mm is best at f/2.8 and the 12mm best at f/4.0~5.6. The prime may be a whisker sharper but no normal human would ever pick it, though (pausing to think) I guess there's enough serious pixel peepers here to see it.

Not a dupe at all, it's darn good and the constant f/2.8 makes AF so reliable even in pathetic light. The extra chunkiness seems to make it easier to hand-hold at lower speeds. In my case I'm spending the kids' inheritance so no worries, though I did wait for the post Christmas discount madness.

But that's it, the 7-14/2.8 and the 40-150/2.8 (when they surface) do not appeal so much as they would not get enough use to justify the $$$. For the maybe 5% of shots at tele the Pana 45-150mm works fine for me on E-PL5, nice to use that Mega OIS for a nice stabilised preview without needing to press buttons. Wider, well I think the 12mm [of the 12-40mm] covers most of what I need and the 9-18mm may gather dust in future.

At which aperture?

Sharpness at which aperture?

Wide-open?

Where it is the sharpest?

The 12-40 at which focal(s)?

You have to be more specific.

I recommend you look at DXO which offers 2D maps of sharpness across the field at various focal lengths and apertures for most Oly lenses.

It does sound rather good.

There is no doubt that the 12-40mm is sharper at the edges at 12mm at all apertures than the prime.

...and I say this as an owner of the prime:(

Dear God...surely it's sharper than the 9-18mm??!! Hopefully it doesn't suffer from the distortion of that lens either.

Define sharpness- edge contrast, resolution?

Overall sharpness averaging the centre, edges and corners or just central sharpness or maybe some other criteria?

Sharpness at what aperture and what focusing distance?

why not look at DXO or some other tests site for quantifiable values?

See that's the difference, 60% of my shots are under 28mm and 90% are 35mm or under I find normal angles of view boring. I have a telephoto prime that I use out of interest occasionally to do sports photography on the beach, and for doing street portraits but that's about it.

A 14mm lequivelant ens interests me greatly hence the 7-14 is high on my list of lenses I want... It stands out and gives you that Panavision/Cinesope look which is both amazing and completely immersive.

I tried to find them all on EM1 to give fair comparisons but couldn't find the pan 15 or 42.5 on the EM1.

Re: Rank Oly lenses in terms of sharpness

To me edge to edge sharpness is important and that's where the 12-40 excels. There may be primes within this focal range that are a tad sharper in the middle but they don't beat the 12-40 in overall sharpness. I sold all my other lenses except for the 40-150 when I bought the 12-40 and I don't miss them.

If you look at a lens, you can see a selector for what cameras a lens has been tested on,    42.5 is tested with lots of cameras, (12MPix on the EM1), 15 is tested on a few cameras too including the EM1 (11MPix).

From what I’ve seen, the 12-40mm wipes the floor with the 12mm prime with regards to edge sharpness.

Uh, the prime "wipes the floor" with the zoom at f/2 even though the edges are noticeably soft.  Stopped down they sharpen up very nicely.
