Would I get a maior improvement in brightness in my viewfinder with the f1.4 lens ? Or not worth the investement. Would it be optically performing better ?

Would it be optically performing better ? When it comes to image quality, talk to anyone other than devotees of Olympus, who will not hear a word spoken against their cameras, and many will tell you that a lot more depends on their quality control (which was at one time notoriously wobbly) than on the lens design. Certainly, when I had both f/2 and f/1.2 Nikkors -- a stop and a half, not just the 2/3 stop difference you are talking about -- I didn't find that the extra brightness made a great difference, though the shallower depth of field it did make focusing easier. To get a good idea of how much difference it would make to brightness, stop your f/1.8 down a little beyond f/2 and use the preview button. Personally I wouldn't bother -- though a 50/1.4 would probably be so cheap nowadays that it wouldn't cost much to find out. If you want bright viewing, consider a rangefinder -- or even a 50mm finder in the accessory shoe of a reflex.

I don't know obout Olympus but with Canon the 1.4 is built to a better standard than the 1.8. If the 1.4 is not too much more, I would go for it...... they definately look better! Woolliscroft 02-13-2007, 05:01 AM I do find the extra bit of brightness a help in low light, although I agree that it is minor. I don't see much of a quality difference, but then that in itself is quite something as it is harder to make faster lenses. At the time, there was a huge price difference, but not any more on the used market and I have been slowly replacing my OM lenses with the faster versions. I recently got the f2 35mm which is a lovely lens. David. BBonte 02-13-2007, 08:07 AM I do find the extra bit of brightness a help in low light, although I agree that it is minor.

I suppose that the difference will be less than moving from f3.5 to f2.0 as I did with buying a 80mm as a replacement of my 135mm f3.5. I hardly use this lens anymore. The f1.4 look more professional. They are still fairly valuable on ebay, the f1.2 even more. Pinholemaster 02-13-2007, 08:14 AM How often do you shoot at f/1.8? How often would you shoot at f/1.4? The difference of viewfinder brightness, unless you are shooting in extreme darkness, is probably not worth the extra expense if you already own the f/1.8 lens. As far as optical performance, if most of your images are shot in "normal" daylight, with the lens stopped down, I doublt if you'll see improved image quality in the final print or transparency. If you are shooting at the edge of extreme lighting conditions wide open, perhaps the f/1.4 will improve image quality slightly when shooting wide-open. You'll see the slight improvement in extreme enlargements. Personally, save your money to buy other lenses. Ulrich Drolshagen 02-13-2007, 10:29 AM It's said that early 1.4/50 are inferior to the 1.8/50 but this might only be hearsay. Seems to be that the same lens designs were used over more than two decades with varying quality standards and different kinds of coatings. The 1.8/50 inscribed "made in japan" on the frontring have an excellent reputation though. I have both, an older 1.4/50 and a mij and can't tell the difference. Ulrich oscroft 02-13-2007, 12:26 PM I've got both the 50/1.4 and the 50/1.8, and there's really not a great deal of difference in viewfinder brightness. I can't really comment on quality difference because my 1.4 is an early single coated silvernose and my 1.8 is a much later multicoated one, and I expect that accounts for most of any differences. frugal 02-13-2007, 12:41 PM The Zuikoholics (of which I am a member) will tell you that the best 50/1.8 is the last version (says "Made in Japan" along the front of the lens) and the best 50/1.4 is those with a serial number higher than 1.1 million (I've never seen anything saying exactly when the last edition came out). Personally, when my 50/1.8 started to go (sticky aperture blades) and wasn't worth being fixed I picked up a 50/1.4 and noticed it was much sharper. I don't know what the serial number of the 50/1.8 was but the 1.4 is in the low 1 millions so I suspect that it's the last version or at least the 2nd last version while my 50/1.8 was probably an earlier version. I had a chance to compare a 50/1.8 and 1.4 in a camera shop several years earlier and I remember not noticing much difference in the brightness in the finder. But, with the difference in the lenses that I had I did find the 1.4 was easier to focus but I suspect this was due to it being a better lens (it's really sharp). Chan Tran 02-13-2007, 03:07 PM I think with most brands the f/1.8 or f/1.7 is a better buy as they are usually significantly less expensive (new) and performance wise about the same as the f/1.4. However, if the price difference is small (as in case of used) I like to have the f/1.4 just because f/1.4 is an even stop (not in between stop). wclavey 02-14-2007, 04:01 PM 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. Simon E 02-14-2007, 05:30 PM 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. fschifano 02-20-2007, 09:16 PM Personally, when my 50/1.8 started to go (sticky aperture blades) and wasn't worth being fixed I picked up a 50/1.4 and noticed it was much sharper... 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. frugal 02-26-2007, 10:08 AM Is it really that much more sharp?

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. |
