Tiffen Vari ND is your best bet at that price:  http://www.bhphotovideo.com/c/product/813278-REG/Tiffen_77VND_77mm_Variable_Neutral_Density.html

Step up rings are fine, step down not so good for obvious reasons

EOS Bodies - For Stills / Re: High Megapixel DLSR a niche market?

When processing speeds (PC, laptop, even phones), storage space, etc make high MP fast and easy, I'd take 100 MP. Why not? It gives more options.

Even for video.  4K video allows you to crop and zoom in post, or create a slider look in post (without using a slider), etc, and still end up with a 1080p finished product.

As the tools get more powerful, we all benefit. And creative people will find unexpected uses for the new abilities, including ultra-high MP cams.

I say ... bring it on baby!

"bootflag"... I don't even know what that means. I have an EOS-M, and might experiment with that first

Sorry, I assumed you already had a look at the ml faq "How to install it": To run ml, you first need to run a tiny, special firmware update that just does only one thing - it sets a "bootflag" inside your camera, after that the Magic Lantern addon firmware is run from your sd/cf card (and only from there). So if you put in another card without ML, your camera is indistinguishable from before.

ML also provides a way to remove the bootflag again, so that Canon service is not able to tell that you were running ml at all - but this doesn't work on the 5d3 yet, they haven't come around to it. But there is no known case where Canon said running ML voids the warranty, so it doesn't matter, but it's fair to mention this point.

Thanks! It would be comforting to know that this flag could be reset

Firmware is still in alpha dev for 5DIII. I've been waiting for a beta release

... the only real issue is that you cannot remove the bootflag if you've set it to enable ml, if that matters to you and you have panic Canon service seeing you're using ml.

"bootflag"... I don't even know what that means. I have an EOS-M, and might experiment with that first

Fyi: All these above features are already available with Magic Lantern for the rest of us :-) ... http://www.magiclantern.fm/forum/index.php?topic=8931

Even though people do the 'math' of, 'well, it's a 1.4 crop factor times a 35mm focal length, so that's right about 50mm....', that is not accurate.  It's still the exact same distortion of a 35mm focal length.

-dave

Distortion is due to the focal distance (except for distortions due to lens design, which is mostly in ultra-wide zooms). 35mm on APS-C = 35 *1.6 FF Equiv =  56mm. Normally this would give little to no observable distortion in adult head and shoulder portraits. But for babies you have to get much closer, and distortion might be noticeable.

I have the 35 f/2 IS and it's a great lens, but if you're doing baby portraits you probably want something tighter. Most baby photographers use an 85 f/1.2 1.4 or 1.8 on a FF camera. That's pretty close to the 50 that you already have (80mm FF equiva.). Move in close to the baby and you should get nice portraits with shallow DOF. If you need tighter, go for the 85 1.8, which is sharp and shallow wide open.

"Exposure Compensation in Auto ISO with Manual Mode Set"

Great feature ...  add to 5DIII please

I can understand the M hate.

That said, I LOVE mine. Its a great purchase, primarily for its 22/f2 that has no full frame equivalent. 

Yes there is a FF equivalent ... the 35 f/2 IS ... on a 5DIII it is far superior to the EOS-M 22 f/2 combo (I have both). Not only does the 35 f/2 have IS, it generates a much shallower DOF on FF, and the 5DIII has similar IQ at ISO 6400 that the EOS-M has at ISO 800.

249
Interesting for sure, but where are the equally interesting lenses?

If they had a couple of really good pancakes, or even just a good 24 2.8 IS, and a 35 or 50 f/2 IS ready to go, I'd be on it like white on rice. But it's still a mirrorless waiting game for me.

250
The 24-105L IS is really good for general purpose video. f/4 is pretty shallow for video and the IS takes out the micro shakes in hand-held /shoulder-support work.

If I didn't do any hand-held video I'd probably sell the 24-105

What could you add to the 70D to make it more video oriented?

Hybrid EVF/OVF viewfinder?
Faster frame rates below 1080p?
Higher resolution (4k)?
Smooth digital video zoom from full-frame to 1:1?
Quad pixel for 4-way AF sensors on every pixel?
Some sort of power zoom lens system?

A ton! No line skipping for FAR less aliasing and moire and better SNR. Focus peaking, live 10x focus box, RAW video recording, non-mangled up compressed video/HDMI out video, zebras, zoomed modes including 1:1, 4k, etc. etc.

I know it's popular if you are a still shooter to laugh off video, but seriously why not expand your creativity to new world. 5D3 ML RAW video is pretty stunning! Some things work better as video, just as some work better as stills and many work equally as well.

+1000

Dissing video means you are afraid of the future
It's here to stay.

Lenses / Re: A New 50 Coming Soon? [CR1]
« on: October 06, 2013, 03:03:42 PM »

 Beginners don't have that kind of money to spend on a 50 (especially one that isn't 1.4).

Who's to say only beginners use a 50mm prime ?

From my point of view there is naf all difference between f1.4 and 1.8 on a 50. I'd much rather have the slightly slower lens with a smaller objective lens and sharp fully open rather than a 1.4 that is really soft at that aperture.

If I'm out hiking in a beautiful landscape looking for pictures I don't want to be lumbered with carrying gear, and that includes a tripod, so IS on a standard or wide angle lens is very useful to me, and I'm sure to others.

50mm has traditionally been a lens that the manufacturer can offer obsolute top image quality with an affordable price tag. Not everybody wants to fork out for and lug around a lens such as the ( albeit fantastic ) 24-70 f2.8 II.

This.

I find it funny how everyone gets in arms about it being 1.8 instead of 1.4.  I have a 50mm 1.4 and I use it at f/2 most of the time.  On FF I find that f/1.4 the DOF is often too narrow, if this 50mm f/1.8 is a good performer I know I'll be all over it  :)

f/1.4 allows you to get shallow DOF at longer focal distances. Not all shallow DOF photography and videography is headshots, in which 1.4, or even 2.8, on FF can be too shallow.

I just got the 35 f/2 IS after the price drop ($550), and it's a good value at that price. Half the size and weight of the Sigma 1.4, very sharp, IS is a bonus!

I hope the new 50 comes out with IS, but I hope it is f/1.4 and sharp wide open. I'd go to $750 if it's 1.4 and sharp wide open. But perhaps $500 for 1.8

How about a new sharp 85 1.8 with IS? That would be worth $900

Only problem I've had is weight. Sometimes I leave it behind because I have a sore neck. My lens has been 100% reliable, and it's worth the price.

Lenses / Re: Do you usually shoot your lenses wide open?
« on: October 01, 2013, 12:05:29 AM »
Depends on lens and subject, but to generalize:

16-35 2.8L II .... usually between 5.6 and 16. Sometimes 22 for DOF, sometimes 2.8 in really low light
24- 105 .... usuall f/4 to 5.6. Occasionally 16-22 for landscape deep DOF
28 2.8 IS .... usually 2.8 - 4
40 2.8 .... hardly ever use it
50 1.4   usually f/2 ... sometimes 5.6 - 11 for incredible sharpness
70-200 2.8 IS II .... usually 2.8. Occasionally 4- 5.6 for easier in focus video
