    Re: My new Oly 12-100mm vs 12-40mm RAW sharpness

    I have to say as soon as I used my 12-100 for the first time I could not believe the difference in sharpness to previous lenses I owned. It really is a special lens . I am sure I will be using mine an awful lot in the future!

      Re: My new Oly 12-100mm vs 12-40mm RAW sharpness

      One of the big 'killers' of perceived sharpness is poor contrast in the image - often caused by internal reflections within a complex lens. It's why old lenses, such as the Zeiss Tessar were so well received. The absolute sharpness may have been nothing special (in modern terms) but the high contrast was a revelation at the time. Images from the 12-100 do show excellent contrast.

        Re: My new Oly 12-100mm vs 12-40mm RAW sharpness

        I have the 12-40 and can't imagine needing anything sharper.
        Constant f/2.8 is a bit slow at times in low light, guessing f/4 is even more of a stretch.
        Looks like a nice lens though and if ultimate sharpness is your thing it sounds just the job.

        These days I judge my photos on screen at an approximation of how they would look at A3 size. Maximum I print at so seems a bit pointless viewing at a pixel level

          Re: My new Oly 12-100mm vs 12-40mm RAW sharpness

          I have to agree about the 12-40 being as much sharpness as anyone can need. It is simply the best lens I’ve ever owned. However, everything I’ve read about the larger lens suggests the 12-100 takes things to the next level. My ideal travel kit, if I were inclined to spend the money at this point, would be the E-M1 mk II and 12-100. As it stands, my older OMD plus 12-40 does nicely.

            That is also my travel kit, do also use a Panasonic GX9 with primes too.
            If anything I would go smaller and get a Panasonic 12-35, but definitely nothing larger than the 12-40.

            Interesting to hear how good the 12-100 is and sounds like more than one pleased owner.

              Re: My new Oly 12-100mm vs 12-40mm RAW sharpness

              I think the 12-100 is quite a dangerous lens to have...? it make you lazy .
              It's definitely my go to lens and rarely leaves my camera unless I'm shooting birds or planes. I used to use a 14-150 Pan/Leica lens (which is also brilliant btw) and then moved to the lighter 14-140 Panasonic lens to ease travel. That was a slight drop in IQ but fine for travel tbh, however, getting the 12-100 certainly gave me IQ back in spades when I switched. I thought I might miss the long telephoto end but I don't for everyday stuff. I definitely like the wider 12mm options it's given me too. So I thought I'd still want the 12-40 to give me more options when the light drops but it turns out I just don't need it, the iso capability of the camera plus the sync IS cope with most things and if I really do need low light capability I reach for my little "Museum" lens the 17mm f1.8. Overall though I'd say I use my 12-100 over 90% of the time.

                Usually her comments are limited to the compositional merit, never the technicalities.

                Is it the optics, the extra 1 stop in IS when used in combination with the EM1:2 or a combination of both.

                Since it's introduction I must have had three at least of the beauty that is the 12-40mm, they were good, very good, but the 12-100mm by far out-performs all of of them.

                My shooting technique has not changed between lenses.

                    Re: My new Oly 12-100mm vs 12-40mm RAW sharpness

                    I got the 12-100 from Wex at TPS, having had the Pana 12-35 and 35-100 f2.8 pair since soon after they came out, long before Oly had the 12-40 and 40-150. They have been my main lenses alongside the ZD 7-14 and now the 7-14 f2.8, and the 75-300. I had a useful wander in the Chilterns yesterday comparing them. I'd say both Pana lenses are slightly sharper some of the time, but pretty close. The 12-100 is better than the 12-35 on branches against the sky, where the latter is sharp, but often gets a bit of PF that is easily dealt with. The 12-100 has very little in the way of CA, and less PF. The 35-100 is always stunningly sharp, with no fringing, and a bit sharper than the 12-100 at 100mm most of the time. The contrast of all three is very good and similar. The Pana lenses both render a bit warmer.

                    I haven't had a chance to compare bokeh at the long end, but suspect the 12-100 is better given the f4 limitation. At the moment, I plan to keep them all, but know I'll have a job removing the 12-100! I'd always keep the 12-35 as it a brilliant lightweight fast zoom, and more comfortable bouncing on the chest than the 12-100! I should say I've never had the 12-40 for comparison.

                      Could also depend on what body is being used.
                      The dual is facility is brand specific, so in my case using the GX9 I would choose the Panasonic lenses.
                      Same goes for the 12-100 and E-M1 mkii, not sure how much extra it gives. Could make a difference and as the saying goes, every little helps

                        I presume you mean dual IS. I've never used the 35-100 IS on my E-M1.1, the IBIS giving good results, and it's one or the other on Oly. I think you need the Mk II 35-100 to get dual IS on a Pana body. The 12-100 has 5 stops on its own, and 6.5 on an E-M1.2, 6 on my E-M1.1 apparently. I suspect Pana bodies might deal with the 12-35 PF better. (Sorry, I see you said "is").

                          The 12-100 is certainly sharp, but it also delivers great contrast/micro-contrast which makes images seem to have just that little extra clarity than a lot of other lenses. The 12-40 is, IMHO, very similar. I reckon it would be impossible to separate them in a blind test.

                          The real ace up the sleeve with the 12-100 is the IS though. Dual IS is notably better than IBIS. For landscape & cityscape, the 12-100 is a dream lens - the focal range, IS and clarity all add up to the perfect tool for the job. The downside of course is the size and the reduced max aperture. I find that f4 is fine for landscape/cityscape use, but as a general purpose lens it's too slow. It's also pretty bulky which makes is less than ideal for street.

                          So, it's definitely a lens I find extremely useful, but I can see that it won't suit everyone. And as Steve (Ricoh) quite correctly points out, there's a lot more to a good image than sharpness.

                            The Dual IS works on the later Panasonic bodies thanks to a firmware update for the MkI lenses, v1.3 I believe
                            G9 has a new improved Dual IS 2 and that does only work with the MkII lenses, my GX9 has only got the bog standard version.

                              Another owner of both and I'm very hard pressed to put one in front of the other from a sharpness point of view.
                              Of course copy variation may explain why others have seen a difference.
