Lenses / POLL: Why everyone reeeeeally wants a 14-24 F/2.8L lens
« on: May 14, 2014, 03:03:40 AM »
Just curious what the true need is for those clamoring for a 14-24.  Is it to have a wide zoom as sharp as Nikon's legendary lens, or is it there something very important about that specific 14-24 FL?

In this poll, you can't have both.  If you had to choose one over the other, which would you take?

Lenses / Sigma 24mm F/1.4 Art lens is apparently in the works!
« on: April 22, 2014, 05:33:55 PM »

The Sigma Art sharpness train keeps on rolling:

And you can't blame them.  That's another fast Canon prime that's only sharp in the center wide open (see graphic from photozone). 

Sorry for those pining for an 85 Art, but at least according to Photo Rumors, the 24 Art is next.

Lenses / Canon teaser for 4/24 announcement -- new fast prime?
« on: April 21, 2014, 08:59:02 PM »

Check it out:

http://photorumors.com/2014/04/21/new-canon-teaser-for-april-24th/

I have no idea how Photo Rumors came to the conclusion that it's a fast prime, but FYI regardless.

I'll be the first to say that this would be a great time to unveil the non-L 50mm F/nooneknows IS lens before everyone gives their ducats to Sigma.   :P

Bryan Carnathan's most excellent TDP website has posted a very nice head to head of IQ of the Sigma 50 Art against 7 similar focal length primes, including the Canon L, Canon 50 1.4 and the Zeiss Otus:

http://www.the-digital-picture.com/News/News-Post.aspx?News=9491

His IQ comparisons are fun if you haven't used them before.  You mouseover the sample shot and the arrow indicator flips to show what image is being shown.  You can change the aperture and see what changes, and he'll eventually even run the same test on crop body (note: he only has FF data on the new Sigma 50 right now). 

By my eyes on these sample shots, the new Sigma Art thoroughly trounces the Canon 50L (as expected) and the Canon 50 F/1.4 (though it's pretty similar after F/4 or so).  The Zeiss, to me, looks sharper wide open, esp. in the corners.  Maybe that's what +$3k buys for you.  :P

Of course, this is not the end-all be-all for a lens review.  I'm sure Bryan will write quite an opus on this one in the next week or two.

But it's looking good.  Have at it and see for yourself!

All,

with all the great Canon Store refurb deals doing on of late, I thought about picking up the 135 F/2L.  With the sale, it would be $696 including shipping, which is a terrific deal.

That lens has a stellar reputation:  this forum and the tests/reviews I've read agree that this lens is an impressive performer.

My only pause in snatching one up is that I already own the stellar 70-200 F/2.8L IS II, and I have to wonder.  Is being one stop quicker really that valuable?  Is the bokeh that magical?  Is it that extra-bit sharper over one of the sharpest zooms made?

Thoughts?  Knowing that I have the 70-200, if I picked the 135 up, would it just sit in my bag for dedicated portraiture work?

If it helps with your answer: 
  • Besides the 70-200, I use a 5D3 with a 24-70 F/4 IS, 28 F/2.8 IS, 40 F/2.8, 50 F/1.4, 100 F/2.8L IS and a 2x T/C.
  • Enthusiast only -- not a pro.

I appreciate the guidance!

Lenses / Poll: How good do you think the Sigma 50 F/1.4 Art will be?
« on: March 21, 2014, 09:23:05 PM »

Odd ranking categories to be fair, but they were the best I could run out quickly.  Given the hype & Sigma's recent track record, I've not offered the possibility that the lens is a dud.

Take 'performance' to mean whatever you choose.  I realize that comparing AF and MF lenses together is impossible given that some folks *must* have AF, but indulge me.

Curious to see how this comes out.  Thanks for voting.

It's sad, but all I have to look forward to is a future date for a price announcement for a lens that isn't even available yet:

Lenses / Hands-On Video with the new Sigma 50mm F/1.4 Art
« on: February 21, 2014, 01:41:27 PM »

Just spotted this hands-on video with the new Sigma 50 at CP+ here:

Sigma 50mm F1.4 DG HSM | ART Small | Large


Not too much going on, but he has a host of side-by-side comparisons for diameter and length.

No news on pricing.   ::)

PowerShot / Underwater Compact that shoots RAW?
« on: February 13, 2014, 12:53:56 PM »

Hello all,

I'm off to do some snorkeling soon, and was considering how I might take pics underwater.  I've considered both a sealed-up housing for either my iPhone or my 5D3 and I didn't want to risk either.  I've decided that I want to rent a waterproof compact camera instead. 

LensRentals offers the Powershot D20, but as you can see, the shots it takes are okay but not so hot:
http://www.flickr.com/search/?q=%22powershot%20D20%22%20underwater

Given that these shots scream for post-processing (color cast, lack of contrast, etc.), I was wondering if any underwater compacts actually shoot in RAW. 

Are you guys aware of any?

Software & Accessories / ND Grad filters question
« on: January 17, 2014, 01:01:27 PM »
Hey gang,

I currently have the Lee filter setup and have the Big Stopper, and a 2 stop hard and 3 stop hard ND grads in my bag.  If I was to add just one soft ND grad to my bag, what would you recommend? 

I am waffling between the 2 and 3 stop versions, and was wondering what your experience has been on that front.  For those who have both, which do you use more?

Thanks!

Software & Accessories / Shade for 5D3 LCD?
« on: January 16, 2014, 12:40:37 PM »

Gang,

I'll be doing some landscape work soon, and I was wondering everyone's take on shading the LCD for LiveView work.

I've seen all kinds of gadgets -- as simple as a three-sided square hood and as complicated as a Hoodman / Zacuto / etc.

I am looking for something that will:
  • Shade my 5D3's LCD from bright sunlight, specifically during LV landscape work.
  • Should be able to stay on the camera without holding it
  • Come on/off easily without requiring significant hardware or any adhesive
  • Not require the bottom or side of the camera / not interrupt my Arca plate
  • As I don't shoot landscape too often, it would be nice (but not mandatory) to be able to see the camera buttons and the LV screen at the same time (for more realtime confirmation of button-press = result), see my ND grad filters and the screen at the same time, etc.

I realize the last requirement effectively kills off the viewfinder-like attachments, but sell me on those if you truly think they are a winner.

I do not shoot video.  Please completely disregard that need with this request.

All said, what do you recommend?  I am game for a product, a jury-rigged contraption, or even a simple best practice.  What's the way to go?

Thx,
A
