Pricewatch Deals / Re: Sigma 24-105 f/4 DG OS Gets its Price
« on: October 25, 2013, 09:11:02 AM »
OK...this is funny...4 posts back on the rumor homepage is the canon 24-105mm alert for $639... That is quite a bit cheaper...plus the Canon has IS.  I am a little slow on the uptake sometimes...but the Sigma has no IS...correct?
I owned the Canon and it is a very decent Zoom lens ...especially at $639!...
I am A Sigma Fan...own the new 35mm....but I am wondering if this lens really best the IQ on the Canon "significantly" asit will have to to sell well, right?

A couple of things.

1) As mentioned previously, Sigma have their own equivalent of Canon's "IS".
2) The 24-105Ls that are selling for $639 are lenses that have been pulled from kits - they're not standalone lenses. Here is the standalone version of the lens priced at $1149 at B&H:
If you look at this page:
Then the Sigma lens is $250 cheaper.
3) If the MTF graphs are anything to by then yes, this lens will easily surpass the current Canon version.

I thought this was real for about 15 seconds.  :o

Don't worry, when the 80D comes out, it will be almost the same as the 75D.

The reason for this is that the 1/3 increments are not hardware based but software emulation of that ISO number.

I don't think Canon knows what to do.

Between Fuji, Nikon, Olympus, Panasonic and Sony, there is a lot of market fragmentation. And that's not even including the phone with a camera.

More with less.
More for less.

Lenses / Re: 70-300mm IS USM or splurge for Tamron 70-200mm VC
« on: October 18, 2013, 04:17:57 AM »
Get the Tamron 70-300 VC Di. It's better than the Canon 70-300 IS USM and around the same price.

I'm not buying one.


Because this new lens mount (FE) and system will not make a 70-200/2.8 any smaller or weight any less.

Sure, for fast primes under 85mm, it might be better - or short zooms in that range too.

But it is the size of the sensor that governs the size of the lens, not the size of the camera or the distance between the lens and sensor.

From http://www.luminous-landscape.com/reviews/cameras/the_new_sony_cameras.shtml:

The world-wide trend is toward smaller cameras. Maybe it's the aging population, or maybe just a Japanese trend that is slowing spreading around the world. (Apparently more than 50% of new DSLR style camera sales in Japan are now Compact System Cameras rather than larger cameras with optical finders).

... which would mean that Canon is currently excluded from 50% of camera sales in Japan. Interesting!

If the lens on your camera is loose then you will lose it.

Lens isn't listed on Sigma's Global site. The links directed to it don't work, and error occurs.
Perhaps they aren't ready to release it?

Given that it didn't appear on dpreview, I think that you're right about that.

But the cat is well and truly out of the bag.

honestly, the mtf doesn't impress me at all. on the other hand, based on what i've seen from sigma with their latest releases, it should be much better than any equivalents canon or nikon has to offer. my guess the price will be around 750-850$ and i really hope it will perform better than what the MTF shows, otherwise, whats the point? if it does i sure see myself getting myself a copy

one thing i dont understand though, is the A rating... a C would make much more sense

The Sigma MTF *is* better than the Canon MTF for the same zoom and the Sigma lens has less distortion. Vignetting - have to wait and see. Will be interesting to read the DxO review of it, that's for sure!

Then, more recently, we bought the 100-300 f2.8 is os hsm (first stabilized version), and after 4 months, we had it back to service.. the stabilizer was broken and making noise. they changed it and it is now ok.
But, 2 sigma lenses = 2 lenses back to sigma.
And, 4 canon lenses, 4 lenses without any problems.
I'm not sure I would buy a new sigma lens...

At least your lens was fixed first time around. I've had the IS stop working in one of the Canon lenses I've got. It took 3 or was it 4 trips to Canon's service department before they fixed it.

However mechanical devices such as lenses don't just spontaneously "break" ...

I'm not interested in this lens, so I don't care much about this rumor. My only hope is that putting a little focusing ring at the bottom of the lens and a big zoom ring at the top, like in the Tamron 24-70/2.8 and in these pictures of the Sigma 24-105, won't become the new trend...
I can't find any good reason for that, while I can find plenty of downsides. I really don't get it.

What colour is your car?

It would be an interesting lens option. Hopefully sharper than the EF 24-105/4 (and my experience with the Sigma GV lenses says that after calibration it probably would be). But at the same time bigger filters and increased weight (and possibly higher cost) would be negatives.

We've been seeing bigger front element sizes on lenses everywhere and I take this to mean that lens manufacturers recognise that with the advent of digital photography people that own *SLRs have become much more interested in IQ.

So if you want smaller lenses with the accompanying smaller filters but you don't want to compromise IQ then you need to move to m4/3.

Or in other words, it isn't possible to deliver a 24-105/f4 for 35mm cameras that is lighter, smaller and has better IQ than the existing lens.
