Pricewatch Deals / Re: LensRentals.com Introduces Keeper
« on: October 03, 2014, 09:17:13 AM »
If you were to buy one that's, say, a year or so into it's life at LensRentals, it's likely a lot less.

They explain in the blog post that you can see an expected price range right on the website before rental. So for instance, on the 5dIII page, you can click "Get Estimate" to see that the expected range is $3,319 - $2,513 depending on the age of the particular copy you get.

I would expect them to price these a little higher than a straight linear interpolation between purchase price and Lens Authority price, because they're losing out on potential rental revenue for the rest of its lifetime, and they need to recoup their costs to procure a new lens and process, test, and tag it. But I still think for many it'll be worth the extra money to get a lens that's been tested, possibly optically adjusted, and that they already know they're happy with.

EOS Bodies - For Stills / Re: EOS Rebel T5i/700D Firmware 1.1.3 Released
« on: January 15, 2014, 07:13:49 PM »
What about the T4i/650D? I imagine this issue affects it too.

Does Canon stop supporting rebels once they've shipped the next annual release?

"CMOS sensor features pixels measuring 19 microns square in size, which is more than 7.5-times the surface area of the pixels on the CMOS sensor incorporated in Canon’s top-of-the-line EOS-1D X.

Exactly! Come on, people - "optimized for Full HD Video" means that it's a 2-megapixel sensor! Do you really want to shoot stills with that on your next EOS camera?

Third Party Manufacturers / Re: Sigma Announces Mount Conversion Service
« on: August 01, 2013, 10:41:12 AM »
I'm impressed that they were able to design their Global Vision lenses in a way that allows mount changes in a cost-effective way. They must have installed common circuitry and algorithms into all of the mounts and just change a pin or a setting to tell the lens which mode to use.

This is something I've seen people asking for on forums for awhile, especially since Sigma started releasing DSLRs. They should provide the service for free (offer to convert all of the purchaser's Sigma lenses to Sigma mounts) if you buy a Sigma SD1 or future DSLR.

This might actually make sigma lenses more attractive than 1st party lenses for people who are worried about getting locked into a system. If you're a landscape photographer shooting with a D800 until canon comes out with something to match, just buy Sigma lenses and you can always have their mounts changed. On the other hand, the cost to do this might be comparable to just flipping them on the used market.

EOS Bodies - For Stills / Re: EOS-M sharper than 6D?
« on: July 18, 2013, 10:55:09 AM »
Is there any chance we're seeing vibrations from mirror slap in the 6D's large mirror?

Might as well use Mirror Lockup for any future test shots just to rule that out.

EOS Bodies / Re: Canon Dual Pixel Liveview Autofocus
« on: July 02, 2013, 10:43:39 AM »
There's a video on the Canon Global website that shows some nice diagrams and explains the process.

http://www.canon.com/news/2013/jul02e.html

Hopefully the added circutry and the inevitable gap from doubling the number of photoreceptors is very small and gives a minimal loss of SNR.

I'm also hoping that the pixels aren't all split in a left/right horizontal pattern, as the video shows, but that half of them are split vertically, because no one would want the AF system to be sensitive to horizontal contrast only.

EOS-M / Re: The New EOS M Firmware in Action
« on: June 20, 2013, 11:04:55 AM »
Excellent, now can we expect this firmware update for on-sensor phase-detect Canon DSLRs as well (650D, 700D, 100D), because they're just as painfully slow in live view.

EOS-M / Re: EF-M 11-22mm f/4-5.6 IS STM Announcement Soon? [CR2]
« on: June 03, 2013, 09:32:32 AM »
Did anyone else raise an eyebrow at the "IS" in that lens name?

I didn't think people really needed to handhold 1-second exposures at 11mm, but I suppose the technology does help sell lenses to novices.

Could someone explain this to me:

When I look at the-digital-picture's wide open test chart shots at 200mm, the Tamron seems to beat the Sigma (or at worst, matches it), but then switch to 400mm (slap on a 2x TC) and the Tamron completely falls apart!

Am I mistaken? Did Bryan completely blow focus? What's going on???

EOS Bodies / Re: A New DSLR Line from Canon? [CR1]
« on: March 12, 2013, 09:06:58 AM »
Could it actually have both DSLR-like AF and an EVF?

Doesn't the reflex mirror required for phase detection AF force you to use an optical viewfinder?

I don't see them mimicking Sony's SLT system. I guess they could use a translucent flip-up mirror, enabling both phase detection and a sort of live view at reduced brightness/sensitivity. Seems pretty far-fetched to me though...

Lenses / Re: DPReview: Canon EF 24-70 f/2.8L II Review
« on: March 07, 2013, 11:10:29 AM »
Of slightly more concern are the ~30% of shots taken between 70-105mm

I would think that the higher sharpness at 70mm, especially stopped down to f/4, would give you the latitude to crop your photos to at least 85 or 90mm and still match the sharpness of the 24-105. This starts getting pretty close to matching the 24-105's usefulness as a walkaround lens, especially if you're not worried about shutter speed.

Did Canon really manage a 1/2-stop transmission improvement over version I?

DPreview didn't mention it at all in their review but it shows in the lens widget when you compare the two lenses.

Lenses / Re: Sigma 50 1.4 or Canon 85 1.8 OR 100 2.0 for 5d mark ii
« on: February 13, 2013, 11:30:55 AM »
... and then my life will be completed!

Haha, good luck with that!

Thanks for updating us on your choice and posting the photos though.

I'm sure you'll be thrilled with the 100 f/2, as long as you can handle its tight crop. It's a slightly sharper, higher-end lens than the 85, so if you found it for the same price, you got a great deal.

Lenses / Re: Sigma 50 1.4 or Canon 85 1.8 OR 100 2.0 for 5d mark ii
« on: February 06, 2013, 10:08:58 AM »
What a fun dilemma to have! (sorry, but I love this kind of stuff!)

As others mentioned, the 85 has the best bokeh and is an outstanding portrait lens but will be too tight for groups and more general purpose photography. The 50 is overall the most versatile lens, but is a little wide for single portraits, and you'd find yourself wishing for a little more background separation.

I can tell you what I'd do: I'd get the Canon 40/2.8 AND the 85/1.8 USED. I just saw the 40/2.8 show up on the used market for $135, so I'm thinking you could get both for the new price of the sigma 50/1.4. Check classifieds, B&H used, Adorama used, and KEH used.

You'd get the best portrait lens for single/couple portraits and shallow DOF photography, but you'd still have an extremely sharp, compact, stealthy, versatile 40mm lens for everything else. You do lose a couple stops with the 40/2.8, but with group photos (and most wide angle shots) you'd end up stopping down a 1.4 to get everything (or everyone) in focus anyway. You also get better macro with the 40/2.8, but you didn't mention that as a priority.

The only real sacrifice with the 40/2.8 is for very low light handheld, but you've still got your 85/1.8, and now that you've gone Full Frame you can ramp up the ISO more than you might expect. Plus, you've only sunk $135 into the 40, so if you really find yourself wanting the extra two stops on a wide lens down the road, you can easily recoup your costs and grab one of the Sigmas. By that time the 40 will also have taught you whether you'd rather have a 35/1.4 or a 50/1.4.

Good Luck!
