Lenses / Re: Guesses on lenses for Photoplus
« on: October 31, 2012, 12:46:15 PM »
The 400/5.6 and 300/4 are AFAIK the oldest lenses in Canon's lineup.  The TS-E 90 and TS-E 45 are due for upgrades similar to the TS-E 24 II.

Released in 1993 and 1999, respectively, they're merely middle-aged in the lineup.  The two non-L TS-E lenses you mention are from 1991.  The 20/2.8 is from 1992, the 100/2 is from 1991, the 35/2 is from 1990, and the 50/2.5 compact macro and 135/2.8 SF are from 1987 (I think those are the oldest lenses in the current lineup).

Lenses / Re: Finally a great standard zoom for full frame?
« on: October 31, 2012, 12:06:24 PM »
The underwhelming optical quality of the 24-105 lens and the missing IS of the 24-70 lenses were two important reasons that have been keeping me away from full frame. I really hope that this is going to change now!

I find comments like this interesting, and a little confusing.  IMO, the best general purpose zoom lens for APS-C is the EF-S 17-55mm f/2.8 IS.  The full frame equivalent of that lens would be a hypothetical 27-88mm f/4.5 lens (f-number in terms of DoF for equivalent framing), meaning the 24-105mm on FF is wider, longer, and faster than the 'best' APS-C standard zoom, and still has IS.  FWIW, the 24-105mm on FF will deliver better all-around IQ than the 17-55mm on APS-C.  So really, nothing should be holding you back from the standpoint of IQ with a standard zoom. 

Now, if you want to talk the cost of the FF system, including replacing EF-S lenses and perhaps buying even longer lenses if you need the reach on FF, that's a different argument.

Yes, the twin flash is pretty much a necessity with the MP-E 65mm. I use it mostly with that, occasionally with the 100L Macro. For the latter, you'll need the Macrolite Adapter 67C.  The MT-24EX clips directly onto the MP-E 65mm.  Note that a filter on the front of the lens prevents mounting the twin lite. Personally, I use filters in all my lenses, but one is very useful on the MP-E 65mm - the working distance is so short I'm always pushing the front of the lens against a bush, etc.  If you want to use a filter with the MP-E 65mm and mount the MT-24EX, get the Macrolite Adapter 58C and mount that in front of the filter.

+1 on the StoFens, I have them.

Been thinking about the RRS brackets - very nice, although the setup costs more than the MT-24EX itself!

EOS Bodies / Re: Official DXOMark Sensor Score for the EOS-1D X
« on: October 31, 2012, 11:50:05 AM »
For anyone wondering why they waited nearly a month after adding 1D X sensor support to DxO Optical Pro to release the 1D X scores, I'd guess it's because they knew there'd be a bit of buzz around these results, and they wanted to drive traffic to their sites now that DxO Optics Pro 8 has just been released. 

How can they rate the D800 better at high ISO noise?

Because the Sports/Low Light Score is based on images downsampled to 8 MP, and when you downsample a 36 MP image to 8 MP, you average out more noise than when you downsample an 18 MP image to 8 MP.

It's a specialty flash, I expect there's virtually no pressure for Canon to update this.

What would be nice?  A major revamp to an -RT system with wireless flash heads (larger to accomodate batteries, probably meaning a more robust mounting bracket), along with the new locking foot design, silent recycle, etc. but realistically, this has got to be near the bottom on Canon's priority list.

I'd say just get it now.

With which lens(es) do you plan on using it?

Lenses / Re: focusing accuracy/repeatability on 50mm
« on: October 30, 2012, 09:34:42 PM »
Did you AFMA the lens, and if so, how?

The 50L has some focus shift - backfocus when stopped down a bit with a close subject (not an issue wide open).

Ordered my 600 II from B&H in late August, received it at the beginning of October. The allotment that covered my order apparently filled all their preorders with some left - it was In Stock on their website for a few hours on the day they prepped my shipment.

What if there was another loss in translation, and this will actually be a 17-70mm f/4L IS.  Now, that would be interesting...

Who would buy the 24-70 II when they could get something with the same focal range that's just as sharp, half the weight, more compact, and 2-3 stops more handholdable? Not many people. A few, but not many.

People who need f/2.8, that's who. Who buys the 85/1.2L with the 85/1.8 available?  Lots of people.

The 24-70 II is like the 70-200mm f/2.8 non-IS lens. Who buys that one?

People who need a sharp f/2.8 but can't afford the 70-200 II.

If they can get the price of the 24-70mm f/4 IS down below $2,000, it's a sure winner.

I bring out the WTF again on this.  The 24-105 f/4L IS close to $1000, if the 24-70 f/4L IS is anywhere even close to $2000, it's a sure big fat loser.

Come announcement time, Canon delivers a lens at around twice the price of the Tamron with marginally better IQ and no image stabilisation. Oops. Tamron out played Canon.

The Tamron lens is cheaper, yes.  One reason is design choices and build quality.  Roger Cicala took apart a Canon 24-70 II and found it to be very robustly built.  He also had an only-glued-in-place element come loose in several of his Tamron 24-70 VC lenses (yes, they're shipped a lot, but the failures also occurred on pretty new lenses).

Lenses / Re: Drop in Filter for EF 500 or 600 f/4L IS II USM
« on: October 30, 2012, 08:58:27 AM »
Thanks but this does not fit for my new lens. you need another for all new II lenses from 300 to 600.

Actually, you don't. The old version fits the new lenses. The only update to the WII version is the color of the 'white' paint (matched to the new white of the MkII superteles). Other than paint color, they're the same and thus forward/backward compatible.

Pricewatch Deals / Re: Canon EOS-M in Stock at Norman Camera
« on: October 30, 2012, 06:35:36 AM »
...swayed by the critics of the autofocus not to pull the trigger.  I am trying to upgrade from a rebel xsi so this will be my first camera for video too.  I want a camera that does both well.  I don't know if I can wait for the t5 as I suspect I'd have to wait a year.  If I don't use the af feature is it hard to do manual focusing?

What's the problem with the T4i's AF??  It inherited the AF sensor of the 40D/50D/60D, a very capable system (to get better, you need a 7D or 5DIII).  I expect the Rebel/xxxD line will keep that AF sensor for the next few update cycles, so if you want better, you'll have a long wait.

Or, did you mean the video AF?  If you want AF during video, that suggests you intend to shoot 'casual' video with a dSLR - there are many reasons why that's not a great idea, and why dSLR video generally involves tripod/fluid head, steadicam, external mic, Zacuto EVF, and other not-cheap accessories.  For casual video, you're better off with a good camcorder, with the dSLR for stills, and for that, the T4i will be very good.
