10x ND filter for 11-24 f/4 L

Does anyone know of a way to take long exposures during the day with this lens using a special filter? Are there any ND filters for this lens?

Does anyone have any experience with this: https://fotodioxpro.co​m/products/wpxlcore-ca1124

Thanks.

IMO, for something that wide, you'de be better off with a rear filter. I think that lens has a gel slot, you should look into cutting out some gels.

the problem has to do with the way the light enters in at a steep angle on the edges. Rear filter would solve those issues. I have a front filter for my voigtlander 10mm, and it's barely usable for a 3 stop filter. 6 and 10 is unusable

I decided on this system after reading the great reviews. I do want something to protect the lens so I bought the UV MRC lens and the 10x stop filter for the XL system. Can't wait to get some creative ultra wide angle shots with this lens!

Thank you for your response. Out of what material do you make a filter that can provide stops for long exposure?

I use haida ND filters, 100mm squares.. for the 11-24 front, you'de need something much larger like 150mm squares.

you can buy them most camera shops.

what do you think about these? https://www.edmundopti​cs.com …q-neutral-density-filter/

Edmund makes quality stuff for optics labs. Those are wratten film filters. I don't think they have the rigidity for a front holder, but you could cut them to size for the rear filter slot.

Edit: The filters in that link are 3-stop filters. Which is fine, but the title of this thread is 10x filters which I read to mean you want a 10-stop filter.

these will not work, way too small for that lens. Best getting a kit like in the original post, just be aware of the severe vignetting which you may encounter with a strong ND. The 11-24 is an unconventional lens which takes unconventional filters.

SW150 Mark II Filter System
(150mm Filters)

The SW150 Mark II Filter Holder has been designed specifically to fit ultra-wideangle lenses.

The design of the SW150 Mark II has been adapted from its predecessor and is now not only compatible with LEE’s range of SW150 neutral density graduated and standard filters, but also the new SW150 polariser and Little, Big & Super Stoppers.

Due to the size of the front element of ultra-wideangle lenses, these filters are larger than those in the standard 100mm range.

I’m curious, you bought the system and dors it work well? Any vignetting issues?

Thanks, for the swift and life saving-answer!! I'll definitely look into Aurora's rear filter set.

They are the result of a Kickstarter (crowd funding) project. I received mine last month so I'm not in a position to criticise or praise but they appear well made and the holders are simple to install (also simple to revert to the Canon original holder). A quick test of a white subject lit with 5600k leds shows little or no colourcast although sunlight might behave differently.

Thanks, very helpful. A heavy price tag, but if it delivers it might be worth it. Please let me know once you post images taken with the filter applied!

It's been grey and stormy for the past 10 days but I'll endevour to test them as soon as possible and drop you a PM to alert you.

Bob

Thanks!
