What to do with $250.

I use an Olympus EPL-1 and the only M4/3 lenses I have are the kit 14~42 and a Sigma 19 2.8. I have several legacy lenses - (28mm, two 50's, 135, big assed Canon zoom).

Two lenses in my budget are the Sigma 30mm and a Panny 14mm from the "bay."

You can look at my flickr account to see which you feel would better suit my style. Suggesting a Ball-Peen hammer or finding another hobby is not helpful but will be considered. 

In time I will update to the Oly EPL-5.

Third option, put that money towards the epl5. You have both those focal lengths covered and neither of those lenses are particularly fast.

Find another $75 and a refurbed Oly 45mm comes into play.

Fourth option, you could pass it my way. Remember, there is more happiness in giving then there is in receiving.

What kind of shooting do you do, or what do you want to be able to do better? There are actually plenty of suggestions for how to spend your money- a tripod, some filters, legacy lens, save up a little more for a lens that provides something new like the samyang 7.5 or olympus 45,  get a viewfinder, etc...

There are too MANY options for how to spend your money, certainly not too FEW. Tell us what you want to be able to do with your camera!

I second this response.  A lot of people talk about "the kind of shooting they do", when it comes to buying new kit I prefer to think of the kind of shooting I want to do.

I have a similiar set up to you, an Oly E-PL2 with the kit zoom and the Pany 20mm.  Earlier in the year I spent about £75 from 2 ND filters and the various adaptor rings.  This has added long exposure shots to my fun.

I have the Oly 40-150 on my wish list for some sports photography that I do.  And I'm going to get a couple of legacy primes to do some portrait/concert photography on a budget.

I'd also recommend a tripod, blooming invaluable in my opinion.

The 14mm will give you a pocketable system.

I use the 17mm pancake on my e-P1 and that is the ONLY camera/lens combination that goes everywhere with me.

Any other bigger lens just gives you another lens : no big deal since you have plenty covered with your manaul lenses.

I have a full stable of filters, a VF3, and a top line Dolica Proline with a DIY short stack for low aspect work.

I even thought of the Panny G3 body as a possible buy. The swivel lcd is a selling point.

Take a look at my flickr page to see what I do. My images are seasonally adjusted.

I see little need for a pocketable camera. My only consideration is what it does in my hand.

What focal lengths do you most often use on your zoom?  What makes you unhappy about using it?

I'm not unhappy with the quality of my (Panasonic) kit zoom at 14mm, so to me the major advantage of the 14mm prime would be pocketability, which you say you don't care about.  To me, that would make the 14 an unlikely choice in your place.

Do you often find yourself shooting with the kit zoom around 30mm? Do you wish for an extra stop there? It doesn't seem to me like the 30mm is offering you that much different, but if that happens to be a favorite focal length, maybe the single stop is worth it.

I generally don't like to upsell people, but I'd say keep saving.  A 45mm 1.8 gives you something entirely different and would be very good for the close up faces that you have a lot of on flicker.  That or keep saving a bit and upgrade the camera if you're looking for better high iso performance or something like that.

It's a legacy zoom, so I rarely use it. Yes I do like getting up close, and the 19mm makes me get inside some people's comfort zone (including mine).  Something like the 30mm would put some space between me and my subjects, and wouldn't distort the face as much. The 45 is a delicious lens, but way out of my price range.

My legacy 50's are usually teamed up with my extension tubes.  I've never really warmed up to zooms. Back in the sixties I had a zoom, but the 50mm was my go to lens. My 14~42 usually stays at 14mm.

The Panny G3 body is of interest.

What about going with the Panny 14~45?

That is an option. It's been several months since I've taken the 19mm off my body. I've been looking at the Panny G3, but it doesn't give much better IQ than the EPL-1. What it does give is better performance, a VF and swivel LCD. IS is not that important. I turned my IS off several months ago, forgot about it and never missed it.

If you're willing to shop around online and buy used from third parties from places like this site's forums, I've seen the 45mm 1.8 go for $290-$325 in excellent declared condition.  As it's only 20-25% over your budget, you might be able to save up.  It would just be more of an investment in hunting down a good deal.

I haven't used the 14-45, though if I could sell my 14-42, I'd be tempted to try it out.  Are you unhappy with your current 14-42?

A friend of mine used to say that.  He was an amateur boxer.

The trouble with resisting temptation is, you never know when you'll get another chance

Thanks. I forget to check out the forums here.  The 14~42 is the first generation model and its just not my cup of tea. I can't use polarizers or graduated filters with it.

The 14~45 has gotten good reviews for IQ.

External flash unit. So important, so often overlooked. Complex to master but so rewarding. If I had the choice of a two lens travel system or single lens and a flash it would be the flash in a heartbeat. Daylight fill flash turns high contrast scenes not even salvageable with Photoshop or Liightroom into perfect ones needing little or no post processing.

That said I am not sure what the price is of an Oly flash currently, it should be less than $300? but I dont know. The third party ones...hmmm.... flash aspect ratio may not be suited to four thirds? Again, dont know. But flash it is.

I rarely use the flash except for fill. I can tilt the built in flash back using my index finger.

Since you seem to like manual focus, perhaps either the Samyang 7.5mm fisheye, or 85mm f/1.4 would be considerations? Both are rather specialty lenses but would offer up something new and fun to shoot with.
