    I have both and 2 bodies, and I personally only notice a difference when I have one of the alternative focusing screens in that works better in brighter light, like the split image diagonal, versus the center spot microprism. The 1.8 makes the diagonal go dark in some cases. I honestly cannot say I have ever noticed a difference in overall sharpness.

    The later multicoated f1.4 lenses are considered the better ones (and definitely an improvement over the early G.Zuiko single coated f1.4 lens), but the difference over the f1.8 lens may be slight. Still, Olympus prices are pretty low these days so they are excellent value. You can buy one and sell it on if you don't like it.

    For improved viewfinder brightness you could try to get hold of the 2-series screens; the 2-13 split-image/microprism is like the standard 1-13, while the 2-4 is all-matte with a circle to mark the area covered by the OM-3/4/Ti spotmeter. But they are very hard to find.

    Is it really that much more sharp? I have a 50 f/1.8 on a little OM-G that I picked up for a song a couple of years back and the lens is really, really nice. Could it be that the f/1.4 version, having a more shallow depth of field, aided you in achieving more critical focus? It's a thought.

    Well, as I had mentioned in my post, I think it has more to do with the which generation each lens is. I'm pretty sure that my 50/1.8 was an early multi-coated version, the later versions (especially the final "Made in Japan" version) are reported to be much better. I seriously doubt the slight change in DoF and brightness is enough to make that much of a difference.

    I know my 50/1.4 is in the 2nd last generation, possibly the last generation but I doubt that. It could also be a particularly good sample (and/or maybe my 1.8 was a particularly bad one). I've shown other people the shots with the lens and also had them focus through the camera and they've remarked about how sharp it is too. That's not to say the 1.8 is a bad lens, just that the improvement I got from my particular 1.4 compared to my particular 1.8 was quite dramatic.

    IF you are having a problem with your images being out of focus when shooting low light, then I bet you are having more of a problem with handholding +slow shutter speed instead of focus accuracy or lens performance.

    While there may be a case for the f1.8 not being as critically sharp as the f1.4, the 50mm f1.8 is designed to produce sharp images. And there is just as much of a case as the f1.4 being less sharp.

    If you are really mis-focussing the lens at f1.8, something will be in focus and it should be obvious where your focus landed.

    OK, so jumping up to a f1.4 lens may help by allowing you to use a faster shutter speed.

    Note that if you are shooting wide-open and having problems focussing, you may have more of a problem with the f1.4 because you have less depth of field. if you are stopping down to f2 or smaller, ignore this.

    Something else: the rangefinder patch of many cameras darken and become unusable at low light. You may want to find a microprism or matte screen. (just a suggestion)

    What body are you using? If you are using an OM1 or OM2, there is a foam in place around the prism, sometimes this deteriates and people think that it's fungus. You may also not have the correct focusing screen, as mentioned. Your lens should stay wide open until the shutter is fired, so if you are looking through a stopped down lens there is a problem there. I have the 1.4, a couple of the 1.8 and a 55mm 1.2. I use them all, but seem to keep the 1.4 on the camera the most (it is a later serial number). If you view finder is brighter with other lenses, then you can do some simple detective work. Viewfinder brightness is a subjective thing. I would guess that you have a 1-3 split prism screen. Price ranges for screens are between $10 and $20, usually, on ebay. The Zuiko Lens Catalogs have screen suggestions at the back, and most screens will still have their compatability charts with them in the box. Sometimes glasses or contacts don't get along with certain screens.

    WTF? how did this happen? There should be a way to lock out threads that are old or considered 'answered'

    Since it's revived...

    The f/1.4 is significantly better overall, it has more iris blades for non-distracting out of focus highlights. At f/1.4 it is soft-focus/diffusion look, at least on the G.Zuiko. I lent it to someone with a f/1.8 and actual OM body (I have a OM-10, I mostly use the lens on a film EOS and digital EOS body), they reckon the viewfinder has a noticeable benefit from f/1.4.

    Focussing is easier with less DoF imho, but you also use split-prism on OM bodies anyway, I am fairly certain the G.Zuiko 50/1.4 resolves over 80 lp/mm at f/5.6 already.

    f/2 the soft-focus/diffusion disappears, better contrast (f/1.4 is still sharp when you examine it, it just doesn't appear to be when comparing stopped down).
    f/2.8+ best contrast
    f/4 very sharp
    f/5.6-f/11 out resolves 83 lp/mm digital sensor (hence my statement above), though there is less-loss of lens sharpness from lens to sensor than from lens to film, for comparable resolution films (similar res at 1.6:1 contrast).

    There are 5 different Zuiko 1.8 and 1.4 lenses. 1.4 above serial number 1,110,000 is the most sought after MC version. If you have the oldest 1.8 (SC with silver edged filter ring, or SC with black FR) The last 1.4 will be an improvement in performance but not so much in brightness. John
