a 49mm ND filter between the 16mm pancake and wide converter?

To anyone using the 16mm F2.8 pancake with converter:


- is it possible to use a 49mm filter between the pancake lens, and the converter?
 
Interesting idea, hadn't thought of that.

Would be interested in the answer myself.

As an aside, does everyone else find the 16mm as soft as me?
 
Heh... nice thought, I have to try that out! I have a 49mm star filter lying around from old times hehe. Would be fun seeing how that would look with the wide angle on top!
Cheesyness! Here I come ;P
 
From another forum, I've got a negative answer to my question :(

Looks like with any filter on the pancake, the bayonet will not work for the converter... Pity.
 
thats why the tokina 11-16 is the best wide angle for the fs100, has 77mm thread, 2.8 and easy to control either nikon or sony alpha mounts.

I'm waiting on my 16mm pancake...any probably the wide convertor...so what are the ND options...matt box?

Probably none - the wide converter has its petal hood fixed permanently, making it problematic to use a matte box (well, yuou can use a matte box actually, but without a filter in it - lol). Bummer :(
 
That's a bummer, I have seen a Sigma 8-16 lens available in Sony A mount. Not very fast as I think it's like F4.5,
but might be OK for the extreme wide angle option.
 
The 16mm is pretty wide without the ultra wide converter. I can't do the math, but simply looking at the footage it gives about the same wide view as the TH13x3.5 (1/3") lens, without the barrel distortion or CA I noticed from time to time. ;)

The Tokina 11-16 is a great wide lens for the FS100, but if you're using it on a handheld stabilizer it's (to) heavy to hold for most people.

Really wish Sony would make a new ultra wide converter for the pancake without the fixed hood!
I'm afraid we'll just have to use high shutters until someone makes a new small ultra wide lens.
 
I need light lens for merlin . At first I thought about 16 mm pancake , but is so soft on the edge . At now I am thinking about sigma 19mm 2.8 . I know it is not so wide as I wish but at least I can use it f2.8 indoor if I have to .
 
I've just got both the 16mm NEX pancake and the 0.75x converter. The pancake does look a bit soft at the edges, but with some apertures (around F8) it's not that bad at all. And the combo gives a very nice & wide look, surprisingly free of excessive barrel etc. Overall, I'm satisfied.

That said, shooting in bright sunshine will require breaking the video rules, and excessive use of high shutter speeds :(

Perhaps you can just leave the wide converter off in those circumstances and use a fixed ND filter?
Too bad we have to choose between high shutter or a less wide view. But the 16mm is still very wide. I always go for the higher shutter, because I really want the ultra wide view on a Steadicam / stabilizer.
 
Hi Derran, nice to see you here :)

Yes - definitely using just the 16mm with ND filter is always an option, for which I'm already prepared...
 
Hi Piotr :)
You have a fixed ND filter for the pancake? Which one did you choose? I have a ND4 which works nice, but I think I've should have gone for one with more f-stops.
 
I'm using one of the 2 options:

- fixed ND8 (3 stops; still not enough to go much below F10 in full sunshine and 1/50th shutter, but flexible enough), used with the petal hood from the 18-55 NEX lens
- the vario-ND (77mm Heliopan; used with Marumi 49->77 step-up ring and the Marumi wide-angle rubber hood)

The latter is much heavier, but gives a complete freedom:)
 
In my experience the 16mm pancake requires a good stopping down just to make it usable. It's very soft at maximum apertures.

A high fixed ND + lots of aperture are the best option for this rather average lens. IIRC F11 is where the lens is sharpest.

I was considering buying the extender for it but will save my money as you can't fix filters.

The Tokina looks like the best option for wider FOVs but not necessarily for Steadicams. If there is a newer version coming maybe the secondhand market will be flooded with upgraders selling their old lenses.

Sorry, but you're contradicting yourself - "high fixed ND+lots of aperture" will made it softer, as you said in your first statement that "the 16mm pancake requires a good stopping down just to make it usable. It's very soft at maximum apertures"

Anyway - I guess this is just wording; we all agree that a mediocre lens like this has a "sweet range" which tends to be narrower than with high quality lenses. This is why I deliberately gave up on the ND 1.5 filter, and bought an ND0.9 instead - now I can use the pancake at F10 which is the middle of the sweet range...

Maximum aperture is when the lens is open most. I think you'll find I did not contradict myself.
