Maybe a bit off topic, but how come a Sigma 10-20 for APSC takes filters without any problem?

Is the difference between 14 and 15mm that significant?

Not sure I am in a position to answer that question in some more definitive way but I'll give it a try. Allowing filters up front means you have to abstain from the bulbous front element used by the Pany 7-14 and several other UWA zooms that go similarly wide, for example, the Nikkor 14-24 for FF, the Sigma 12-24 for FF, the Sigma 8-16 for APS-C, and the old (FT) as well as upcoming (MFT) Olympus 7-14. I would think that has drawbacks optically, e.g., with regard to vignetting, more so the wider you go. In addition, you have to go to wider and wider filter diameters and/or make the front element flatter and flatter to fit a front-mounted without mechanical vignetting due to the filter ring. At a certain point, the design concessions you have to make in order to allow filters up front simply become too large.

Just adding, "on request", a quick-and-dirty picture to show how things look with a filter (in this case a Wratten 2A) fitted in the holder:

Sorry but I can't see the filter in the holder, I did make the rear modify and I'm on the search for a Wratten 2A,2E filter in Europe , if you have any new info about filter availability let me know, thanks a lot for the hole effort.

That means I made a good picture. Look at the edges where the holder is open and you'll see it. In this kind of light, the filter is nearly invisible with regard to color.

The supply situation when it comes to these filters is generally problematic because hardly anyone really wants or needs them for the purpose they were originally made for. In the U.S. it is still relatively easy to source them I think. In Europe, it's a mess except for the few items that may still be available from old stock or used. Here's the latest thread I am aware of with some British supply channels for 2E.

Re: My 7-14 takes filters ... at the rear end

If anyone is still struggling with this fix solution, feel free to contact me.   I have a ready-made holder with Wratten 2A gel filter.  All you need is a small screw driver to install it on the Pany 7-14 lens.  I followed the instruction on this thread to created that.  I was quite happy with it.  However I just sold my 7-14 lens as I needed the fund.  If you want, I can sell you my fix kit at cost+shipping.

Excellent work and ingenuity.  I was thinking about getting this lens.  
It seems the wait  for the Zuiko 7-14/f2.8 is for more than just an extra stop.

Yes. On the other hand, for those who don't want to wait and/or find the higher weight, bulk, and (in all likelihood) price of the M.Zuiko 7-14/2.8 undesirable, there is, as this thread shows, a solution to the special problem encountered with the Panasonic 7-14/4 when used on Olympus bodies.

True Anders .. for me, I can access the lens ad-hoc so there is no need to buy it. Lucky me, except that I doubt its owner will want me modifying his lens.

Probably best for others to see 7-14/f2.8 Zuiko before criticising it, though.

it does not look that much bigger, If it isn't > 500g and is noticeably sharper it might well be worth the wait and cost.

My two 40-150 l(the 4.05.6 and the 2.8) lenses differ greatly in weight and size. Guess which is almost never on the camera? it might be a similar story. With the 9-18, it makes three MFT lens choices .. three quality levels and three different size/price and quality "settings".

.

Weather resistance is always good IMO and as a long term proposition it tends to keep out fungus.

Now, if weight is really an issue the 9mm/f1.8 PRO might be a good alternative at 2.3 stops faster than the panny - I hope that's weather sealed too.  It is said to be VERY small/light and the 12-40 does go reasonably close and is very good wide open.

.
With a tripod and stitching, two images can make very wide images on the odd occasion some of us want super wide - no good with moving subjects, of course    
Great choices we are starting to get!

Based on the measurements here,

http://www.43rumors.com/the-big-olympus-pro-lens-size-comparison/

which have so far proven to be quite accurate, it will be quite a bit bigger and in all likelihood heavier than the 7-14/4. As to weight, I think 500 g is about the smallest value we can hope for. Then it remains for each of us to decide whether the extra bulk, weight, and (likely) cost is worth it of course. To me, the extra stop isn't particularly important for a lens like this. Weather sealing is always nice but not essential to me either. But if it turns out to be extraordinarily good optically, I may consider it nevertheless.

It probably is weather sealed. I guess that's something Olympus wants to offer as standard with their PRO line. But it's pretty big in comparison with the Samyang 7.5/3.5 FE and in this case too, I find the extra speed to be of limited interest. Further, I don't really think of an FE as a substitute for a rectilinear UWA. OK, you can reproject UWA images to look more "fishy" and the other way around. But the AoV of the FE is much greater even when "defished" and it is far from always that I want to go quite that wide.

It is said to be VERY small/light and the 12-40 does go reasonably close and is very good wide open.

Agree. It IS specified as being weather sealed and suited not just to interiors but also to the great outdoors, which as we know can be most inclement.

.

A real storm chaser's lens and it is metal, not plastic..
Based on their previous efforts, it will likely be even sharper than Pana.

.
My guess about 500g is probably close as it matches other's guesses.
2.8 is 2.8 is 2.8 .. to paraphrase Gertrude (who paraphrased Bill Shakespeare)

.
The likely increase in price is not much for 100% more light - look at other lenses where one can make this comparison - it is never cheap and certainly never free.

.
Oh, I have the Samyang and like it for what it is.
Sharper than the equivalent panny too, it is said.
It certainly satisfies my "need" for "bent" pictiures

This little gem of a lens (P. 7-14mm f4.0) takes superb pictures. I don't need an extra stop and I don't want the extra weight and size (and can't afford that much money). Now I have to re-study your instructions, Anders, and get my old hands to be a little steadier (and get up the nerve) to modify this lens to get along with my O. E-P5. Wish me luck!

Bobby

PS, what's the dimensions on your clear plastic insert, Anders?

That's you Bobby, and that's just fine. The difference in new price is about 30%, not counting specials which a new product never gets.
In 3 months it'll be 15%.

I prefer less CA than I noticed on the one I sometimes I have ready access to. It is difficult to control in UWA lenses, particularly zooms.

I also like weather sealing and inclement conditions are is just the sort of environment I'd drag such a lens into

If you already have a 7-14 and are happy it is probably smart to keep it.

I am more interested in the 9mm f1.8 that was rumoured...
Hopefully it isn't a pipe dream as I want such a lens for night work.

Oh, and good luck

I certainly do. As I said in an earlier reply to you, you do need fairly steady hands for parts of the job, perhaps even more for cutting/inserting the piece of "gel" filter without finger-printing it or otherwise harming it than for mounting the filter holder.

You can't really wipe a piece of "gel" (it's actually a kind of plastic these days) clean again if you get some grease on it, at least not the older Kodak version I first got. Possibly it works better with newer stuff. The only thing I ever use to "clean" my own piece of gel is a rocket blower. The basic rule for the filter is to keep your hands off.

I used tweezers, gripping the piece of gel at one extreme corner only, to get the piece of gel in the position required to push it into the holder. Once there, I let go with the tweezers, no longer gripping the piece, and instead turned the tweezers 90 degrees so that I could push at the filter edge with the edge of the tweezers, thereby getting it into its final position.

When you cut the "gel" to proper size (see here for instructions), remember to keep the protective layers of paper in which the filter is delivered in place. If the packaging remains the same as with the fairly old "gel" I bought, there is an exterior cardboard "envelope" followed by a layer of aluminum foil. You need to take the "gel" out of those before cutting. But then there are two layers of protective paper, one thicker, more card-board like, followed by a thinner, and I recommend that you keep those on the filter when cutting it.

Hopefully, you can, if you find it necessary, get someone to help you with the most difficult "moves" after you have prepared everything. It's not a particularly difficult or time-consuming job for someone with reasonably good dexterity. I am not particularly dexterous myself, and I still managed it so ... .

Bobby

PS, what's the dimensions on your clear plastic insert, Anders?

I am afraid I no longer know. It seems I threw the rest away. But I took as thick a piece of plastic packaging material as I could find. You can easily see for yourself what thickness you need. You need to get enough filling to match the height of the inner ring that I show and talk about here (fourth picture). Even if the plastic itself isn't quite thick enough to manage that, you'll thicken it an extra bit when you make holds in it for the screws to go through.

An alternative to using a plastic insert (shim) the way I did, is to simply shave off the protruding part of the inner ring with a knife as explained by Vasyl Tsvirkunov here. Although I haven't tried to do that myself, I think it might work just as well, perhaps better, than the solution I used.

Only rumors about a 9 mm f/1.8 that I could find were from August 2014, and seemed to be quite uncertain. It might well be that what was actually rumored here was the 8 mm f/1.8 fisheye that has now been released. What, if anything, have you come across that might have us think differently?

I drew up the attached template for use with 100mm sq Wratten filter. Print, IIRC, at 300dpi. The actual squares are 21.5mm each and the tartan pattern is clearance between squares.

Don't cut 'a square' cut a strip and then individual squares after that.

Having cut a square you will need to measure 2.5mm in each corner (especially the inner corners) and cut a triangle off. But of course, you'll practice all this with a piece of cartridge paper first won't you?

The filter 'gel' is quite brittle - I lost the first because it cracked as I was cutting it, through not holding it down firmly enough. But my first success is still in use on the lens 10months later!

PDF for 100mm sq Wratten filters - this is 90mm sq to allow margin on outside too! Print at 300dpi.

Hope it helps

PS, what's the dimensions on your clear plastic insert, Anders?

I am afraid I no longer know. It seems I threw the rest away. But I took as thick a piece of plastic packaging material as I could find. You can easily see for yourself what thickness you need. You need to get enough filling to match the height of the inner ring that I show and talk about here (fourth picture). Even if the plastic itself isn't quite thick enough to manage that, you'll thicken it an extra bit when you make holds in it for the screws to go through.

An alternative to using a plastic insert (shim) the way I did, is to simply shave off the protruding part of the inner ring with a knife as explained by Vasyl Tsvirkunov here. Although I haven't tried to do that myself, I think it might work just as well, perhaps better, than the solution I used.

I drew up the attached template for use with 100mm sq Wratten filter. Print, IIRC, at 300dpi. The actual squares are 21.5mm each and the tartan pattern is clearance between squares.

Don't cut 'a square' cut a strip and then individual squares after that.

Having cut a square you will need to measure 2.5mm in each corner (especially the inner corners) and cut a triangle off. But of course, you'll practice all this with a piece of cartridge paper first won't you?

The filter 'gel' is quite brittle - I lost the first because it cracked as I was cutting it, through not holding it down firmly enough. But my first success is still in use on the lens 10months later!

PDF for 100mm sq Wratten filters - this is 90mm sq to allow margin on outside too! Print at 300dpi.

Hope it helps

Thanks for helping out with additional advice Mike. You might be right that it helps to cut a stripe first (although I didn't on the much smaller piece, 2x2 inch, that I first bought).

And yes, if you take just a little bit of care not to hit the filter with your fingers when switching lenses, there is usually no need to frequently replace the piece of gel. I am still using the piece I put there two years ago.

Thanks to Anders and Mike for these last two instructive post and another kudo to Anders for inventing this solution! Also thanks to Vasyl Tsvirkunov for instructions on shaving down the new filter holder to fit more precisely, I think I will follow your method and shave this part down as I will be better at this with old but careful hands.

Re: My 7-14 takes filters ... at the rear end

I didn't read the whole thread, but I've read enough to know the essentials.

I have a hard time deciding whether or not to buy a E-m5 mkii or not with my Pana 7-14mm. I like the articulated screen and I love all the creative stuff you can do with this camera.

Two questions:

Teninwien suggests in this post that his 20mm behaves better on the mkii than on the mki. I guess someone has tested the mkii for purple blotches with the 7-14? Is it less sensitive? Or is it a no go without the rear filter?

I live in Belgium. I can order the filter in the UK - knights - and it will probably cost me around 100€.. I've seen the thread with the German supplier of panasonic spare parts, so that should work out as well.

I've not decided yet if I'm going to do this. But in case I buy the mkii, is there someone in the region who has like half a filter and is willing to sell it? It seems a but stupid if we all buy a full one, no?

I am not sure texinwien and you are thinking about the same thing with regard to the Pany 20/1.7.

The 20/1.7 has no trouble with purple flare when used on an Oly body. This problem is unique to the 7-14/4.

The 20/1.7 has some problems with purple fringing when used on Oly body. This problem is not peculiar to the 20/1.7. Purple fringing generally gets a little bit worse than it would otherwise be when a Pany lens is used on an Oly body (see here for further information). The reason is partly (but only partly) the same as with the purple flare you get with the 7-14/4: Weaker on-sensor UV filter in Oly bodies. The cure is therefore also the same: Add a filter that brings UV filtering up to the same strength as the on-sensor UV filter used in Pany bodies. But if you don't want to do that, the purple fringing is easier to deal with in PP than the purple flare.

What I think texinwien might have been thinking of is a third problem: The 20/1.7 (not other Pany lenses) can cause banding (pattern noise) when used on certain bodies. The banding usually shows up only at pretty high ISOs or when you push shadows. In contrast to the two problems mentioned above, this is not really a Pany-Oly compatibility problem. It has to do with the sensor. The banding appears with bodies using the presumably Sony-designed sensor introduced with the E-M5 and used in many other Oly bodies after that. But the Pany GH3 uses this sensor too and has the same problem (it's even mentioned in the GH3 manual). It may be that something has been done with the E-M5.2 to alleviate this problem. I already know that texinwien has seen less of it with his E-M5.2 than with his E-M5 and I have seen positive reports from others too.

I guess someone has tested the mkii for purple blotches with the 7-14? Is it less sensitive? Or is it a no go without the rear filter?

I don't know if anyone has tested it yet. But I'd be a bit surprised if anything has changed in comparison with earlier Oly bodies in this particular regard. It would mean that Oly would have increased the strength of their on-sensor UV filter compared to the strength they have previously standardized on.

I live in Belgium. I can order the filter in the UK - knights - and it will probably cost me around 100€.. I've seen the thread with the German supplier of panasonic spare parts, so that should work out as well.

I am aware that the required type of filter is a bit hard to source outside the US, which is unfortunate. I hope you will manage to put together a reasonable deal in the end.
