what's needed:

don't listen to anyone who tells you it "can't be done"...
cokin X-pro filters (yes only cokin officially makes them, but format will if you custom order)
cokin x-pro holder (you could also hand hold)
95mm threaded adapter ring for x-pro
1 lance armstrong livestrong wristband!!!!


yes this works. yes it's that easy. All you really need is the X-pro filter. It works with the filter 90 to the lens and a bit past, but ~30 of angle on the filter (using the holder) makes it vignette. And no you can not use a CP with this setup (at least my GIGANTIC X-pro one won't work). But this is the setup that will get you filters working on crazy wide lenses.

I also have a spare lens barrel/cap deal on order from sigma. Once it's here I'll mill off the lip on the end and permanently attach it to the 95mm ring (it's almost a perfect fit now, ie you need a hammer ;)). That will make it cleaner/easier/better looking, but the wrist band works. :lol:

2 more shots to gave you a better look:

on canon's wide lens's there is a filter slot on the back of the lens on the mount. I cut ND gels in 1.25 inch squares and use that.

jacobsen1
07-24-2009, 05:15 PM
yep, the siggy's got the slot too. Tried it once on my old one and couldn't stand it... If I feel I need a ND AND 12mm at the same time, I'll fund a panel ND in the x-pro size (format will custom make them). Basically, if I keep the 12-24, I'll get one, if not I'll sell all my X-pro crap in favor of Zs. :lol:

So, Ben I was wondering if you could help me out here please :)

I am going to get the Cokin X-pro filter holder for my x-pro grad ND/14-24 combo and also get a 2-stop ND filter. I measured the outside diameter of the 14-24 lens hood and it's 98mm. The adapter that is closest to that size is a 105mm one:
http://www.bhphotovideo.com/c/product/168528-REG/Cokin_CX405_X_Pro_105mm_Adapter_Ring.html

Would this be a good choice? Thanks so much for any info! :)

jacobsen1
08-28-2009, 03:31 PM
yeah, actually I thought of that the other day when I was Nikon shopping and forgot to bump this. You need whichever size is the next one up. 105 will obviously work but if they made something closer it would be better. Basically you'll just need more padding between the two to make it close (my rubber/livestrong band). But yes, that will work. :)

smizar

Got this set-up from B&H:
1) Cokin X-Pro 153 Gray Neutral Density (ND) 4x Resin Filter
2) Cokin X-Pro Filter Holder
3) Cokin X-Pro 105mm Adapter Ring

It gets here Wed and will try and get the rig together :)

jacobsen1
09-24-2009, 09:28 PM
OK, I got my 14-24mm holder done:
http://gear.benjacobsenphoto.com/wp-content/gallery/nikkor-14-24mm/bbj_0975.jpg

http://gear.benjacobsenphoto.com/wp-content/gallery/nikkor-14-24mm/bbj_0978.jpg

it's a cokin 105mm X pro adapter ring and a spare lenscap from Nikon. You punch out the center of the spare cap then I actually filed down the OD on the tip of the cap so it could slide into the cokin ring if that makes sense... Basically, the lenscap is as "long" as it was, it's just been turned into a doughnut, then the outside tip was files so it's OD matched the ID of the cokin. Then they're glued together. You slide it onto the lens so it's just in the corners of the pedals (not quite flush) and you won't see the holder on the edges and the filter itself just clears the pedals.

Now all I have to do is sort out a good way to block the light up in the top corners (my roll of tape has been working well ;)).

That's awesome! Thanks for putting these pics up! My current x-pro rig uses the elastic bands to attach the adapter to the lens hood - not as stable as I would like. Will give this lens-cap rig a shot :)

all I need now is the 14-24! I am a few thousand short though... I guess my DX 12-24 will be the workhorse for a while.

Thought some of you might appreciate this. The first ~2:30 is a basic GND tutorial really, then I dive into how to use filters on lenses that can't use them in the traditional sense. I shoot my video reviews in one take early in the morning w/o any practice really, I'm sure that's painfully obvious, but it is what it is. I find I'm more honest that way. ;)


http://www.youtube.com/watch?v=Y0s2Q_JlPcE
http://gear.benjacobsenphoto.com/2010/accessories/filters-for-lenses-that-cant-take-filters/

so, anyone sit through the whole ~8:30? How bad do I sound?
remember, this is wicked early in the AM, unrehearsed and done in ONE take w/o any practice... Should I keep doing these or stop? Suggestions on other video reviews?

For me, the audio is distracting. Too much natural sound.
And tight shots of what you're explaining would help to break it up and make it more visually interesting.

But I realize that would be kind of tough, being it's just you doing everything.

jacobsen1
04-19-2010, 11:32 AM
^ :lol: yeah, I was thinking about bringing some of the parts closer to the camera for "close ups" but w/o a way to see what the camera was seeing I didn't want to miss not getting it in frame. I could look into a better mic though if I keep doing these. Shotgun w/ a muffle? I do them outside like that so they're not super boring interior/office videos.

NewsPhotog

You could get something like a Sennheiser ME-80 or ME-66 with a Softie windscreen, or even better, a lavaliere mic like a Sony ECM-44. With the windiness of that spot, though, a lav mic might not be the best choice- but if used with a fuzzy windscreen or worn under a shirt, you'd hear yourself talking much more clearly.

thomps6s

I watched the whole thing, found it pretty interesting. If I had those lenses, it would be helpful.

jacobsen1
04-19-2010, 11:47 AM
what about a shotgun mic with the big fuzzy thing though? Wouldn't that (pointed at me) get more of my audio and less wind?

Yeah, that's what the ME-66 with a Rycote Softie windscreen is. Sorry, I should have been more clear. :)

The only bad thing about that setup? The mic runs around $500, and the windscreen another $100.

yeah, I'm clueless for video (obviously).

^Probably not- as it's not a very directional mic. It's meant more for natural sound- whatever's happening around the camera. Not all shotgun-style mics are of the actual "shotgun" style, with a very directional pickup pattern. Mono mics are better for on-camera talent because it's better to have only one audio channel because it makes listening easier on the ears.

Audio, like lenses, is one of those things where you get what you pay for. Spend more, and the quality shows.

Most likely to get better audio recording a better microphone can help but depending on the internals of the camera a preamplifier may be necessary to produce a cleaner sound overall. Unbalanced audio in general is not going to provide the best resulting audio track.

Overall, I found it acceptable.. obviously some different close ups would be nice, but it was in no way painful to watch, in comparison to many tutorials i've seen. You made a few mistakes, but that's ok.. there would be some nice to haves like close ups and those "example" shots thrown into the video at various points.. but that's not something you couldn't do with the current footage after the fact.

Good work overall..

jacobsen1
04-23-2010, 05:10 PM
^ this issue with the is I want this to be very easy for me to publish so slicing in other clips or shots makes it much harder to do... But I also want these to be good enough people WANT to see them and they're a good resource, so that's why I'm asking.

if you go to my site for the review:
http://gear.benjacobsenphoto.com/2010/accessories/filters-for-lenses-that-cant-take-filters/

I do have a ton of sample shots, and shots of the filter holders ETC worked in at the bottom Eric, is that "good enough" or would you still work them into the video itself so you don't need to use the site at all?

I have a few bags with me for this weekend I'm thinking about doing this for, I'll do them with BOTH the GF1 and 5Dii this time to see any audio or video differences.

Blazin
04-23-2010, 06:04 PM
AHh.. see I had the youtube link off the main NSOP page.. from there I just went to BJP.com and didn't easily (5 min) find it.. you kept referring to the shots.. so I wanted to see them. If you're really interested take a look at the magic lantern firmware for the 5DII.. it adds in better audio controls, some of it isn't needed with the latest firmware upgrade, but you may find some advanced features that you'll like.

As for the splicing in the shots.. are you doing this on imovie? I can't imagine it being THAT hard on a mac :wave:

I was glued for the 8 mins.. and I still wanted to see those pictures.. and I did go to your site. SO that's a plus, if you're the average person? I don't know if it would bring them to go to your page or not.. but it worked for me...

jacobsen1
04-25-2010, 04:22 PM
the average person got linked to the right page on my site though... ;) :lol:

here's the review there:
http://gear.benjacobsenphoto.com/2010/accessories/filters-for-lenses-that-cant-take-filters/

and yeah, I've considered the magic lantern firmware but haven't been bothered. I shoot with MF lenses anyway (I have to with my 5Dii!) so it's just the audio and zebra upgrades. I suppose it would be fun to have though? I'm playing with the GF1 as the camera to do these with thanks to it's much smaller size but I'm not there with it yet (for starters it's audio is MUCH worse). I shot some video on both cameras today but the 5Dii footage looks enough better I'll probably stick with it.

which sigma? Zs don't work on the 12-24mm on FF but they will on other lenses in a similar fashion.
I'll likely be selling my Xs here pretty soon though. ;)

When I got my Sigma 8-16 I found this video and how to setup the filters - Thanks Ben.
Project done and sold the lens - It was a love and hate relationship with that lens. Very sharp and fun but the auto focus was not up to par especially on the 60D - Don't have time to send the camera and lens to Sigma to have them mess with it.

Used similar rig as Ben showed without the yellow band and P size filter instead - Found a tad vignetted so I backed off to between 9-10 mm. Unfortunately, turned in my files to client - cannot post the file and sold the lens and rig to the local camera dealer here for 24-105 - Got the 10-22 EF-S instead and like it a lot.
