    A technical query.

    I tend to shoot jpegs with my panasonic bodies and lenses. I can tweak the output in camera and have been more than pleased with results.

    I am now thinking of getting the oly 45 1.8 and maybe the 35 1.8. Bearing in mind they are essentially designed for oly electronics, will they produce good JPEGs straight from my GX7/G3. I dont really want to use RAW etc.

    Thanks

    I used the Oly 17/1.8 and 45/1.8 on the GX7 when I had it for a few weeks. They work perfectly. I saw no difference in the JPGs versus when I used the P14 or P20 on the GX7.

    Thanks. Probably worrying about a problem that does not exist.

    Regards

    Olympus lenses don't have any built-in chromatic aberration [edit: CA correction], no matter what body you use them on.

    Chromatic Abberation

    I take it you mean the body electronics don't correct this.

    The lens electronics, yes.

    This raises an interesting point. Presumably all lenses have optical faults (i.e. CA, vignetting, loss of sharpness etc) because they are optical and made of glass. I understand that in camera processing of m4/3 bodies corrects some the worst of these defects.

    You imply that the lens being electronic can also correct optical faults. I did not realise that this was the case. Sorry for being a bit thick but I am trying to get my head round this.

    Regards

    I'm no expert but I understand the chip with the correction details is in the lens. The Olympus lenses' chips contains data for distortion correction and vignetting correction. The Panasonic lenses' chips contain data for distortion correction, vignetting correction, and CA correction. The body doesn't have a database of lens data, it reads the lens chip and applies the correction. Olympus body firmware is unable to process the CA correction data on a Panasonic lens. IIRC.

    Have used Oly 45 and 25 on my GX7 and have seen no noticeable difference vs. JPGs from my E-M5. Note I am not a hyper-technical shooter nor do I pixel peep so I could be missing differences not visible to the eye on my computer monitor. That said, no complaints at all, GX7 JPGs are great with the Oly lenses.

    I love my GX7 with the OLY 12mm.. I have been using this combo for my street shooting and it is sweet! All i shoot is jpg from my Gx7 and EM5/EP5!
