I agree. I didn't pay it much attention the first time I saw it, but the more I look at it the more I like it...especially the way the yellow and blue work together. The ceiling shows off the mustache distortion a bit, too I wouldn't even notice it, except I was just playing with the correction plug-in the other day, and so got a bit sensitized to it.

Just been building a filter holder (to hold standard Lee filters) for this lens. A few things to iron out but it seems to be working fine.
I'm using it on a crop - i think it would probably vignette on full frame and would require the larger 150mm filters.
Will post pics soon.

A couple of quick examples with filters (these are converted from raw with ACR but not edited):

Without Filter or Holder:


With Filter holder and Lee 0.9 ND Grad (Hard edge):


Filter holder and Grad filter on camera:


So there is some vignetting with the filter holder - I feel I can fix this easily by trimming some of the corners. (For full frame I think that you would have to either cut the lens hood or use a different style holder with 150mm filters).
Also there is some light leakage (I could see that on some other shots) - I think this should be an easy fix also as I just need to add a small amount of rubber (which I have used for the slot) around the edge that the filter sits on.

Thoughts?

give us more detail on the stock you are building up for a mounting surface to the lee filter holder and how you are attaching, i.e. modifying the filter holder any? I know the filter holder screw-on rings go up the 85mm thread...I shoot full-frame would would definitively need a larger filter. I wish these filters didn't cost so much...would love a long sheet of a .9 GND filter to cut as I need.

I know what you mean about the cost of the large filters...

So I started with a base of cardboard - made that into a circle to fit over the lens. Used another couple of cardboard circles to reinforce it also. (When I redo the design I will use pipe -90mm would work well - because that would be sturdier).
I filled the inside with a few layers of masking tape so that it fit snugly with the lens and wont fall off (but is still easy enough to get on/rotate)
Around the outside I put some foam (door sealing stuff that has an adhesive side already) - this was mostly to reinforce the holder... but at the front where the filter sits I put 3 layers of the foam so that I could stick the filter guides on the side.
I didn't use an entire lee holder, just a set of filter guides - measured the 100mm for the filters and stuck a piece of rubber where the filters will sit (as the back edge).
Then I screwed the filter guides into the rubber+through the foam.
On the inside of the filter holder is also a very thin layer of foam that protects the filter from hitting the lens hood.

Hope that made sense... It didn't take long to make at all.

The foam on the inside is what I have now trimmed so that the corners aren't cut in photos.
I'm not sure how this would go with stacking filters - if it doesn't work then I will consider cutting the longer pieces of the lens hood so I can bring the filters closer to the front element. (This is possibly a way of using this holder with a full frame camera also).

Thanks Al


Well spotted on the mustache distortion, I did notice this but thought it could nearly have been a design feature of the building, it was designed by Frank Lloyd Wright. (now im thinking i should have ran it through PT!)

I don't think people would notice unless they actually looked for it. Then again, I'm not very sensitive to distortion. In fact, I rather like it in most cases. I reeeaaaallly wish that the Samyang would make a fisheye for full frame (they have excellent ones for both crops and m4/3 systems).

hi everyone,

I made an observation in another thread:
http://photography-on-the.net/forum/...2#post14175912

could everyone kindly comment if my observation is legit or not?

thanks

M

p.s. is it necessary if I close my other thread and continue the discussion in this thread?

Bobby T, those are awesome! That's the way I like to think of this lens, as an everyday, indoors thing.

[BobbyT]

Thank you. This lens is a blast to shoot with.

Just won an auction on eBay for one of these for the nice sum of 130€. It's a Walimex branded one. Would anyone know how to tell if it's the UMC version or not? And if so, what are the differences between both? Is one much better than the other?

I'm pretty certain the only difference is the name written on the side

Yeah, but there is a UMC and older non-UMC version. I wouldn't know how to tell with the Walimex.
