EOS Bodies - For Stills / Re: Cards for 6D
« on: August 20, 2013, 12:55:57 AM »
Any decent UHS-1 SDXC card should be fine and I think that 64GB cards are the sweet spot in price/capacity these days, so it's around $50 (40-60).

I'm using Transcend USB 3.0 reader and it gives me all the speeds they claim on each card (like ~80MB/s UHS-1). It is cheap, small and it works. If someone is interested, model number TS-RDF8K

1st. Win7 has a silly way to calculate file transferring speed. It shows the progress of data migration to memory buffer instead of the final destination.
2nd. This bug is very obvious with larger files when the source drive has faster copying speed than writing speed of the destination drive, it hangs at 99% (or before finishing each file in a sequence) while waiting for data to finish writing from memory buffer.
Have a look at the other USB devices you have connected; My cellphone for instance causes some screwiness when I have it plugged in.

Some USB devices do not "play nice" with others, you better not use them simultaneously, specially on the same USB hub.

4th. Try copying to a different hard drive (not sure about 11-12MB/s, but if the one you are using is near full it's writing speed may drop below 30MB/s) or using a different USB 3.0 reader.

Good news. I'd like it to be the second generation of Sigma's wide Macro lenses (24/1.8Macro, 28/1.8Macro).

maybe there is some new canon body and lens in testing?  ;)  ;D

OMG, giants exist!  ;D

Lenses / Re: 40mm f2.8 STM - Lens Hood?

I have 52mm-to-58mm filter adapter which looks very much like the ES-52 lens hood :). Perhaps it could act like one as well.

Not only is it arbitrary, but it also changes over time.  For example, when I was growing up, 28mm lenses were far more common than 24mm lenses.  But these days, I doubt many people are buying 28mm lenses - all the interest is in 24mm lenses or wider. 

The same could be said for 85mm.  While appreciating that many people buy 85mm lenses, I suspect that the "standard" longer prime would be in the 90-135mm range (especially when you consider all of the macro lenses in that range that are sold).

I agree with the 24mm vs 28
But 85mm is still by far the most popular short telephoto.
B&H has almost 1400 reviews of the 85 1.8, and only 90 reviews of the 100 f/2, even though these two lenses are about the same price, same size, and deliver the same IQ

IMHO, if there was EF 75mm f/1.4 USM for the same price, then it would beat the 85/1.8 ;)

EOS-M / Re: Am I missing something in the math/conversion here?
« on: August 05, 2013, 11:55:30 AM »
I'm getting an M. Mostly this will be my Parks (WDW) travel setup where the 5D3 is too bulky/heavy.

I'm thinking for Animal Kingdom in bringing the M with the Tamron 70-200 + 1.4 TC. I get 448mm @ f/4. Is that right?
The "M" is APS C, so you will see a angle of view 1.6 X that of a 200mm lens, or 320mm.
Have you tried one with the Tamron? I would not expect it to work well with a Tamron lens, it may be extremely slow to focus.  Most third party lenses do not play well with Canon's live view.  There is no phase detect with a EOS M, so try first or make sure you can return it.
With a huge lens, the body size makes only a slight difference, and balance may be poor.  You might be far better off with a SL1 and the ability to use phase detect AF if you want a small body.  Tamron Af will work reasonably well with phase detect.
Good Luck.

SX50'HS is a nice, small, almost pocketable, cheap super telephoto, but if you want better IQ, then you should avoid TC's on zoom lenses as well. Otherwise, you won't get a much better result than a super-zoom P&S camera.

Canonwatch has what is purported to be a leaked image, would seem this beast is getting a bit less mythical.

Looks fake to me.
120-300/2.8 and 18-35/1.8 photoshopped hybrid.

Canon will be showing off their new headquarters, that's all :).

Actually, it would (kind of) make sense if every next FL had around 2x smaller FoV, like:

If you compare fast Canon L primes
24/14~1.71 >> 1.71*1.71~2.92x
35/24~1.46 >> 1.46*1.46~2.13x
50/35~1.43 >> 1.43*1.43~2.04x
85/50=1.7 >> 1.7*1.7=2.89x
135/85~1.59 >> 1.59*1.59~2.53x
200/135~1.48 >> 1.48*1.48~2.19x
then you'll see that they are not evenly spaced. The FoV difference varies from around 2x to almost 3x.

Sigma 24-70 f/2 OS HSM - great! It could be THE lens for videographers. Now let's think about it realistically:
very BIG, very HEAVY, not weather-sealed (most likely);
much more expensive than 24-70/2.8L'II, could be $3k+ (just look at the 120-300/2.8 ).

Copy images, never move.  Make sure your copy is good, and then make sure you have a backup of that location.  Only then, format the card to make it squeaky clean.

I load many cards as copy and paste after a trip and keep the originals until I am done with all the PP and copy / backup the final images.  Only then will I delete or reformat the card.

+NEVER touch the contacts on SD cards, because static electricity may corrupt the data.

Transcend USB 3.0 Super Speed Multi-Card Reader (SD/SDHC/SDXC/MS/CF)

Importing images directly from camera using the USB cable has a higher chance to corrupt your images, specially if it is connected through a hub along with other USB devices. USB 3.0 is much faster.
