Is f2.8 enough?

Hi all,

I'm using the standard 14-42 kit zoom with and E-500, set to 25mm to mimic a 50mm prime.

I'm wondering whether the f2.8 of the 25mm pancake is going to improve the reduction in DOF and low-light performance significantly?

With the kit zoom the max aperture is around f5.6 I think.

I'm cost-conscious and read that the E-500 is difficult to use with a manual focus OM set-up.

Thanks

Richard

Nope! not difficult at all, but you won't find anything with the sort of aperture you really need (f1.8) at 25mm. There are plenty of OM 50mm F1.8's out there going for peanuts, if you can't hack it manually, stick it back on ebay.

There's nothing wrong with the E-500 (has the Kodak sensor), while it may have been superseded by lots of newer models, it's still quite capable.

There's a photo on another 4/3 forum that was taken on a camera phone, and as someone commented, it just goes to prove it's the photographer not the camera........

Re: Is f2.8 enough?

Excellent, sounds promising.

What should I look for in a 4/3 adaptor?

I presume I would be buying a 25mm OM lens with manual aperture ring.

Well I can think of the OM 24mm f2, 28mm f2 and Vivitar 28mm f1.9 off the top of my head but I'm sure there are others I've forgotten.

Re: Is f2.8 enough?

I reccomend the Vivitar 24mm f2.8, should fit the bill nicely. Until I can get hold of a Zuiko 21mm at a non stupid price it will remain my main lens.

I assume that from your shallow DOF requirements you're going to be shooting pretty close up, in which case focussing is a breeze. It's really not as much effort as people seem to think, plus when you do set it to F22 you are getting the DOF of F22 in the viewfinder, not F2.8 so theres so little out of focus even if you can't see what you're focusing on chances are it'll be fine!

Here's a sample, and if you want more then have a look in my Holes in Walls thread, and on fiur thirds user look at my Granite Quarry thread, all taken with this lens.

25mm @ f/2 the dof is 0.46 feet with the subject at 4 feet from the camera.
25mm @ f/2.8 the dof is 0.65 feet with the subject at 4 feet from the camera.
25mm @f/3.5 the dof is 0.8 feet with the subject at 4 feet from the camera.
50mm @f/1.8 the dof is 0.41 feet with the subject at 8 feet from the camera.

Yes! but at what price???

Also I would have thought that for street photography 50mm (100mm) would be better than 25mm (50mm standard) especially when wanting to control depth of field or perhaps I am thinking of a different form of street photography....

I think I paid 29 for my Vivitar 35mm f1.9 so it paid for itself the first time I licensed a photo from it.

I got it because I needed a disposable fastish wide angle I could afford to lose.

Ah but 35m(70mm) is closer to the 25mm(50mm) than the 50mm (100mm) so if at a good price may be more suitable

Re: Is f2.8 enough?

As ever, these innocent questions become much more complex.

I hadn't considered the distance to the DOF area, but even though I can try shooting at 84mm (42 on the kit zoom), the aperture is f4.2 maximum.

So I'm concluding so far that it's probably worth trying the 50mm OM solution first (I've seen an f1.4 on ebay), and get used to composing photos at 100mm.

Re: Is f2.8 enough?

Just taken the plunge and bought a multi-coated 50mm f1.8 for 22 off ebay. Another 27 for an adaptor on top.
Can't wait to experiment further!

But it's closer than the 50mm you were talking about.

You won't be disappointed with the 50mm/1.8, it's a joy to use. Not a bad price - mine was 21 but was from a non tog who didnt know much about it, and hadnt realised it was attached to a Tamron 2x teleconverter, which usually sell for more than that on their own!

Nice deal: I once bought a very clean Tamron zoom with Nikon mount for 15, sold the mount for 13.

Back to the original question: You might try a 28mm f2 or f2.8 to mimic an old style standard lens, and in fact I did the same a couple of years ago with my E400, but I found it very difficult to focus accurately.

These days I restrict myself to 50mm and longer for legacy lenses, but that may just be an eyesight thing. A 50 f1.8 will certainly give you nice tight DoF and should be a cheap solution.
