Lenses / Re: How do you think we should spend the money?

A few other key items I'd like to mention are:

#1 Get a WhiBal card for 34.95.  It will allow you you to fine tune and get the accurate White Balance setting in the room.  Order it from the Michael Tapes web site.  What a difference especially without a flash, the custom white balance within the camera will be dead on perfect with this card.  http://michaeltapesdesign.com/

#2, if you get a 7D, there's a built in wireless transmitter to use with your (hopeful) 580EX II is a huge plus so another words the 580EXII can be used off camera and hand held by your wife or on a stand.  You can configure it with the built in flash to add fill or without the built in flash (solo).  You can also set up the Master / Slave combo with an A+B+C flash (for future if you get more than one flash such as a secondary 430 EX or another 580 EXII).  The manual settings of the 7D's built in flash and the 580 EXII allow a great deal of combinations.  The diffuser on the 580EXII works with UWA lenses up to 15mm as I recall and the white pull down card is great for eye sparkle.  It also has a full 180° swivel head.  The 580EXII in most cases knows exactly the lens that is on the camera and can auto adjust when using E-TTL

Neuro -  as expected, you raise some very good arguments with MM thickness of the filters stacked.  The Hoya HD Pro ND64 is 3mm though I am not sure about the Marumi Super DHG CPL.  The test I did was on a 7D and at 15mm (with the 15-85mm lens so I am really at 24mm (approx).  It sounds like the 5D Mkiii is coming out later this month though I suspect I will get it in April after a tax refund.  If there is vignetting with the two stacked then yes, I won't have a choice but to move to the 10 stopper. 

Wickid..I didn't think the fader was soft I just found that on Max ( and near max) it was uneven with light distribution (see tests above). Per the Light Craft Facebook page, the tech rep stated I would only get 3-5 stops maximum on that Light Craft Digi Pro HD Fader filter with the 16-35 mkii lens on 16mm.  Wish I would have known that in advance.

Hi Neuro - I just did a test with a Hoya ND400 with and without a Marumi Polarizer.  The polarizer was stacked on top, not first.  The Polarizer added 2 stops as expected and actually balanced and improved the ND400 on its own (that was suprising).

With those results in hand and since there is no 82mm Hoya ND400, I think I'm going to try the Hoya Pro Digital HD ND64 (6 stops)(this was the most I could find at 82 in Hoya brand) and then add the Marumi Super DHG Cir. PL for an additional 2 stops.  Hoping that this total of 8 will be enough with my daytime shots.  With limited budget in hand (couldn't get all 3 meaning the added 10 stopper), I felt the Polarizer was key for most daytime shooting whereas the ND's are a 2nd priority.  Still mouth watering over the 10 stopper though just perhaps a bit down the road.

I'll post some results once they arrive..

Hi Neuro - you are welcome.

Yes, I distinctly recall your recommendation and that is next on the list.  Is there a single coated and multi coated version on this one?

With respect to the above tests, I figured let me go for one of the best Vari's and newest (Light Craft stated the one I had tested above replaces their MKii's) and .. well the results speak for themselves.  So I think I'll get this 10 you recommended and need one in between like a Hoya ND64 unless you have another recommendation

DeadPixel

On the site you reference earlier, http://the-digital-picture.com , click TOOLS, ISO1233, then pick the 15-85mm on one end and the 16-35 mkii on the other.  Notice how both lenses are extremely close in edge sharpness.  The only reason I got the 16-35 (also own the 15-85) is I plan on acquiring the 5D mkiii when it arrives later this year.

In my honest opinion, the 15-85 is a fantastic walk around lens.  I've taken some of my best photos with it.  The reason why it is not as expensive as some of the L lenses is that it costs less to reproduce as per my initial inquiry with Canon as are "all" EF-S lenses.  If you use flickr, there's a group that features photos with this lens specifcally http://www.flickr.com/groups/canon1585/pool/with/6774142481/ . I also own the 100mm 2.8 L.  It's razor sharp as others have stated and offers a unique feature that is limited to only this lens which is Macro AI Servo (I believe is the exact name).

Hope this helps you

Light Craft for Canon 16-35mm Mkii:  Fader ND Digi Pro-HD Round 82mm Results

Recently I had acquired the Canon 16-35 mkii and immediately began my quest for a set of ND filters or potentially choosing a high quality variable fader.  I opted for the latter and selected the Light Craft top of the line Fader ND Digi Pro-HD Round which claims to range between ND2-ND1000 for $320 USD.  I read several reviews, chatted with Light Craft on Facebook and sent off a few emails.

I acquired the filter today and found smooth threading, excellent package and a convenient handle to increase or decrease the fader settings on the ring.  The results were unfortunately not even close to the Hoya ND400.

Since Hoya doesn't make an ND400 for the 82mm, I was swapping the 16-35 with the Light Craft Fader and the 15-85 EF-s lens with the ND 400 by Hoya.  The settings were aperture priority at 5.6, ISO automatic as well as speed.  This was my conclusion (Hoya ND400 photos are #1 and #4 and the Light Craft are #2 and #3).

Discrepancies:

1)With the ND400 in place, the camera required more light if you notice (via EXIF) the ISO adjusted to a higher setting @ 1600 and the shutter speed between photos 1 & 2 went from 1/25 to 1/30 thus the ND400 requried more light

2)On photos 3 and 4, photo# 3 with Light Craft auto adjusted to ISO 400 and 1/25th while photo number 4 jumped to ISO 1250 and shutter remained the same

3)also, the darkness aspect should be equal on both filters but was not.  One would think on Max it should be ND1000 as the ads exclaim or at least ND500.  I would suspect on the Light Craft Max is about 7-8 stops certainly not 9.

Lastly, there’s a distinct lighting unevenness with the LCM filter on photos 2 and 3 vs. the Hoya which is more solid across the screen on photos 1 and 4.  Sadly, the Light Craft is going back.  I'm not sure how many folks have an ND400 laying around but without it, these tests could not have been possible and are the proof in the pudding.

As always I am open to objection or rebuttals or any thoughts you wish to share.

I rarely use photomatix these days but every once in a while i got back to it to play around
I have found that avoiding the temptation to push the strength slider too high has a big impact on how real the scene looks. I try to stay below strength 70

I also find night shots and urban shots can sustain higher strength values before they get to oh my god my eyes are bleeding levels.

I find photomatix automatically oversaturates and outright alters the colours and there is nothing you can do about it. Its too hard to fix this un natural colour shifting afterwards

I do agree with you.  After I am done tweaking in Photmatix, I give it another overhaul in ACDSee Pro 3.  correcting pretty much whatever needs to be done.  Thanks for the link, off to work but will have a peek soon.

These are all good points in addition though, if shot in color under the same conditions, you can create a recipe and apply to all wanted images for B&W use within DPP via batch process.

534
I'm curious as to anyone's thoughts on this.  I am sure we all realize the immediate advantage of shooting everything in color, then post processing into B&W but why have Monochrome as a built in option on the EOS camera's?  Is there an advantage choosing Monochrome on the EOS Bodies over post processing the color RAW into B&W?

Allou - excellent work on your photos.  Do you primarily use an ND filter?

John, some of those are truly excellent especially the perspectives, DOF and lighting - well done.

K-amps, thanks for the kind words
