EOS Bodies - For Stills / Re: How to differentiate crop vs. FF
« on: October 13, 2014, 10:14:57 AM »
The differences are "neg•li•gi•ble".
Everything else is just noise and a lot of geeking out.
I must politely disagree.

Lenses / Re: used 300 f2.8 IS or new sigma 120-300 f2.8

Although I haven't try 200mm f2 with x1.4 yet, but I have feeling it can't win the bare 300mm f2.8 IS II in term of IQ.

TDP agrees with you:

Let us know how the f/2L trial works out for you  :P

Thanks to everyone for their input.

I ended up picking up the 90mm. I'm looking forward to learning how to use this beast over the winter :)

1D X Sample Images / Re: Any Thing shot with a 1Dx

Using the Sidney Opera house as a canvas, with its everything but flat surface, but still creating a flat image illusion is quite something.

Actually, all of the roof surfaces are sphere surface pieces. There is a nice exhibit around the entrance of the Opera house that explains how Jorn Utzon finally came up with the solution to how to make the roofs (relatively) simple to manufacture.

Sandisk usually includes free recovery software vouchers with their high end cards. I have had to use this once when I accidentally formatted a cf card. The recovery software saved the day. Maybe the other manufacturers also include this, but after my experience I'm sticking with sandisk.

Lexar do that too. Or at least I got licenses with the 1000x cards I bought a couple of years back.

EOS Bodies / Re: A New EOS Pro Body With 46mp Next Month? [CR1]
« on: September 19, 2014, 02:43:38 AM »
At this stage take this rumor with a pinch of salt. Canon has senior camera, lens and sensor engineers at Photokina asking pro photographers what they like and dislike about existing cameras and lenses in three different groups. You dont do that with the associated cost if your about to launch a camera in a month.

Surely they can and will do that (talking to customers about what they like/dislike and launch a new body in 1 month).

My point is that Canon is most likely to have multiple generations of camera bodies under development at the same time, considering the product development time vs the launch cadence, so the camera they would be about to launch would not the one they are taking input on.

That body should be called 1DXs, not 1Ds X - after all, it will have pixels INXS!  ;D

@NancyP:
As I said in the first post, it's the selective focus I want to work with, so I'm leaning towards the longer focal length end (90mm). The only thing going against this is that I don't have a studio, so space is limited ... which means that 90mm could be too long  :(

Thanks for the idea about the MF lens, but since I've never used anything bigger than 35mm film, this is not an option to me.

@Mackgyver:
I'm not sure if lack of ND and CPL is a problem for me, but it's worthwhile to remember. I already have 82mm ND & CPL, so this is in favour of the 24L II.
Thanks for pointing out the Vince LaForet videos, they are quite good. I just went back and re-watched Episode 3.

This is all very interesting. I have only cameras with SD cards, and I always did low level format in the camera, every time. Performance of these cards has stayed stable with time. CF, if faster, merits a look. Any comments on a good card reader? I have a MacBookPro with a SD slot built in, so I have not used a card reader before.

I have the Lexar Professional USB3.0 Dual-Slot Reader (it takes both CF & SD) and I am extremely happy with it. It can do sustained 90-100MB/sec downloads from a Lexar 1000x 32GB card to the local SSD drive (Samsung 840 Evo). At USD35 @ B&H, it's pretty inexpensive too.

Depending on which MBP you have, it may or may not have USB3. If it doesn't, consider looking for a Thunderbolt based reader.

Just remember that the card itself is only half the story.  The other half is the camera.  For example, you can put as fast an SD card as you want into the 5DIII, but it isn't going to write faster than 20 MB/s.  Shooting JPEG on the 5DIII, you'll be limited to less than 50 MB/s.  The camera becomes the limitation in both these scenarios. 

http://robgalbraith.com/camera_wb_multi_page7de5.html?cid=6007-12452

And 18MB/s if you write JPGs to the SD slot.

As for bent pins, I haven't experienced that in 10 years of using CF cards, but my stepmom recently bent several pins on an poorly designed* card reader.

*) Poorly designed because the pins aren't recessed enough in the body, so it is easy to mis-align the CF card when inserting it. At least it wasn't her camera body :)

IMO: I'd stay with the SD cards you have now, and evaluate if I needed to move to CF cards later for speed.

Edit: spelling

My GAS status is now up-north. This could be the last purchase for 2014  :)

Famous last words, or just because you'll buy it on Dec 31st? :D

my ruthless annoying complaining has finally worn the boss (my wife) down and I have been given permission to seek the 300 2.8.  But how to obtain such nirvana.

1)300 2.8 L IS II…just kidding you didn't really think I could do that did you?
2)300 2.8 L IS I…seems like it can be purchased for around 3500 depending upon from where/condition etc
3)Sigma 120-300 sport (around 3500 again)

The main differences from my experience is that the MkII is lighter and has better IS. It is slated to take the 2xx MkIII TC better, focus slightly faster and be slightly optically sharper than the MkI, but I didn't notice that.
I guess you already checked out Bryan's review on TDP.

Considering that the MkII is about 2x the price of a well-kept MkI (at least where I am), you need very (very) good reasons to go for the MkII.

The 300's are quite handholdable at 2,35-2,55kg, even with the 2x TC, whereas the Sigma 120-300mm is 3,4kgs.

I have the 17-40/4L, but I'm lusting for the 16-35/4L IS.

Yes, I'm a geek and I have GAS.  ;D

Lenses / Re: The Sigma 35mm Art is Toasting Canon's?
« on: September 17, 2014, 05:43:21 AM »
The optical performance is really good, but several people have reported about AF consistency issues here, even after going through 2-3-4 copies of the 35A and 50A lenses.

The amount of issues have at been enough to at least discourage myself from looking further into getting a 50A at the moment.

Thanks for all the comments, I really appreciate the collective knowledge and wisdom here.

Keep in mind when making that decision that ably the newer MkII 17mm & 24mm are in fact 'L' Lenses, the older build 45 & 90 are not.

There are differences between the two, there's an expectation that quite soon Canon will upgrade the 45 & 90, so you may want to hold on your decision for a while, but with Canon lately you may also want to ignore that & decide which of the current 17 & 24 suits your needs best.
Indeed. I stopped waiting for the 7D2 two years ago and bought the 5D3, as an example. But the point about the independent rotation of tilt & shift is duly noted.

I would recommend the MII 24mm, both 24mm are L's but the MkII is considerably better both in IQ and functionality.

It will give you more "selective focus" control than the 17, it takes standard sized filters, with a 2XTC it will go to 48mm so you get even more selective focus.

The 45mm is a comparative dog, it desperately needs upgrading.

Hmmm. Using TDP's ISO charts to compare a 24mm L II + 2x TC with the 45mm, and there the 24mm+2xTC are quite soft in the center (even when comparing f/7.1 vs f/2.8 ). Stopping the 45mm down to f/5.6 or f/8 makes it sharper all around.
What am I missing here?

The 90mm blows the 45mm out of the water, optically. Especially if you put the 2x TC on the 45mm, it gets horrible.

As for the price, the 45mm and 90mm are in the 5.000-6.100DKK range (USD870-1.060), whereas the 24L MkII is 9.500DKK (USD1.650).

Since noone have objected to my statement about 17mm & 24mm = architecture and 90mm = product shots, I presume this is right. I guess the addition is now "45mm = The Dog, avoid it at all cost" ;D
