LensRentals.com Contest to Win a MacBook Pro w/Retina Display

From LensRentals.com
A good partner of ours, LensRentals.com is running a contest to win a MacBook Pro w/Retina Display. Apparently people like the laptop and think the screen is pretty good. I might be one of those people.

I’ll say it right off the bat, the contest is for US residents only. It’s not because LensRentals.com dislikes the rest of the planet, it’s just about laws, borders and that sort of thing.

The contest info is in the graphic below (Click for larger).

The Raw Data: The EF 24-70 f/2.8L II is the Sharpest Zoom Canon Has Ever Made

The Raw Data: The EF 24-70 f/2.8L II is the Sharpest Zoom Canon Has Ever Made

From LensRentals.com
Roger over at LensRentals.com ran the new EF 24-70 f/2.8L II through an Imatest session and found it to be a stellar performer as far as resolution goes. 

From Roger
“This is short, sweet, and simple. The resolution absolutely, positively kicks butt and takes names. It is way better than the lens it replaces. It’s better at 70mm than the best Canon zoom I know of, the 70-200 f/2.8 IS II. It’s even better at 24mm than the sharpest 24mm prime we have, the Canon 24 TS-E. In the center, in the corners, it doesn’t care. We only had 5 copies to test, but they were all very similar with little copy-to-copy variation.

Resolution is not everything, of course. But it’s certainly an important thing. Unless the real lens reviewers find some dramatic problems with this lens, I’d have to lean towards worth-the-money on this one. I can’t believe I’m saying that a $2,300 standard zoom is worth the money. But then again, I can’t believe I’m seeing a zoom lens out resolve a $2,000 world-class prime, either.”

The Imatest results are below. The higher the number, the better.
Lens 24mm Ctr 24mm Avg 70mm Ctr 70mm Avg
Canon 24-70 f/2.8 II 954 831 950 809
Canon 24-70 f/2.8 730 605 705 570
Tamron 24-70 f/2.8 VC 815 765 735 655
Canon 70-200 f/2.8 IS II xx xx 885 765
Canon24 f/3.5 TS-E 915 775 xx xx

As you can see, the new EF 24-70 f/2.8L II is an absolute resolution monster. It really looks like it’s the best zoom Canon has ever made optically. There is a small note that distortion at 24mm is slightly worse than version 1, but that’s what software is for. :)

A Small Sigma 180 f/2.8 OS Macro Issue

Issue with the new Sigma Macro
An issue with the Sigma 180mm f/2.8 OS Macro on the 5D Mark III and EOS-1D X has been discovered by LensRentals.com. If this has caused anyone to pull their hair out, the solution is pretty simple, just turn off illumination correction.

Below is an image taken by LensRentals.com showing the phenomenon.

Sigma 180 f/2.8 OS Macro Issue – Click for larger

The Findings

  1. The phenomenon shows up on Canon 5D Mk III and 1Dx cameras only. T4i and 7D bodies with firmware upgrade do NOT do this, nor do any other older cameras we could test.
  2. The Sigma 180 OS and Sigma 150 OS macro lenses both show the effect and it’s identical. No other Sigma lenses that we stock showed the effect, nor did any Tamron or Tokina lenses. Obviously I can’t test what we don’t carry.
  3. If you turn off Illumination Correction in the menu the effect goes away. To repeat, though, Illumination Correction in the 7D and T4i, on or off, doesn’t cause the effect.

The issue probably doesn’t show up on the APS_C cameras because of the image is about the same size as the circular anomaly in the center of the above image.

Canon EF 24 f/2.8 IS & EF 28 f/2.8 IS Quick Review

Canon EF 24 f/2.8 IS & EF 28 f/2.8 IS Quick Review

From LensRentals.com
Roger Cicala at LensRentals.com has put the two new Canon primes through a resolution test and compared them to other lenses in the Canon lineup.

A lot of people are still a bit confused by these two lenses, however their size and decent performance may find a place in the market.

MTF 50 Resolution Test

Conclusion

The bottom line is these are both nice, sharp lenses. Certainly sharper than the current 24-70 f/2.8 L zoom (we’ll have to see if they’re sharper than the 24-70 Mk II) and better than the 24mm and 28mm lenses that they – well, I guess replace. Although I have trouble considering a lens a replacement when the price has jumped 200% to 300%.

Canon EF 40mm f/2.8 STM Quick Review

Canon EF 40mm f/2.8 STM Quick Review

From Roger at LensRentals.com
As Roger does, he received the new Canon EF 40mm f/2.8 STM lens and had to immediately put it through the paces.

Roger did some computer aided tests to check the sharpness at MTF 50 and compared it with other higher end Canon zoom lenses, and it turns out the little pancake outperformed them in some areas.

Roger’s Conclusion

Overall, though, I’m extremely impressed. I’d be impressed if a lens this size and price was just decent, but this one is excellent. I might as well go ahead and get in trouble with the business manager: if you think you want this lens, just go ahead and buy it. At this price, unless some of the more thorough reviewers find something I missed on this quick overview, you can’t go wrong.

Tamron EF 24-70 f/2.8 VC in Stock & Quick MTF Review

Tamron EF 24-70 f/2.8 VC in Stock & Quick MTF Review

Tamron EF 24-70 f/2.8 VC
Don’t want to wait for the new Canon EF 24-70 f/2.8L II? Don’t feel like spending $2200? Wanted some form of image stabilization, perhaps the new Tamron 24-70 f/2.8 VC is for you.

Quick MTF Review
Roger at Lensrentals.com also did a quick and dirty MTF comparison between the new Tamron 24-70 f/2.8 VC and the current Canon EF 24-70 f/2.8L. The Tamron faired quite well.

 

Tamron 24-70 f/2.8 VC vs Canon EF 24-70 f/2.8L (Higher numbers are better)

Roger also mentions the autofocus performance is pretty good on the Tamron, maybe not as quick as the Canon, but much faster than Tamron’s 70-200.

You can read the entire quick and dirty review at LensRentals.com here.

5D3/X and Other Random News

5D3/X and Other Random News

5D Mark III / 5D X
There has been nothing new to report on the recent leaked DSLR from Canon. Keep your thoughts and opinions coming though.

Rebel T4i & 70D [CR1]
I have received little bits of info in regards to the replacement to the T3i and 60D, both will be “addressed” by the time Photokina rolls around (probably a lot sooner). Nothing in regards to specs or direction at this time. There’s a general opinion Canon will announce their mirrorless camera for Photokina in September.

Meanwhile [NL] is told that a new Rebel will be announced at CP+

Announcement date?
My [CR3] level source in regards to announcement dates has yet to see one for CP+. Although it has been confirmed that Nikon will announce that day. It may just be a Coolpix day for them though.

5D Mark II at the Oscars
A movie shot with the 5D Mark II has been nominated for an Oscar. So fear not, even if the new 5D Mark III makes it way to us soon, your 5D Mark II is still very capable.

Article: All About Coatings

Article: All About Coatings

New Article: Reflections on reflections. Coatings: The Most Important Part of Your Lens
We are posting another article written by Roger Cicala at LensRentals.com.

Todays article touches on coatings. Their history, and their importance in optical design. As always, it’s pretty informative..

So How do Coatings Work?
It’s pretty simple to explain if you have a Ph. D. in optical physics and speak higher order mathematics. I don’t, so I’ll just have to explain it to you like it was explained to me (and I’ll put some references at the end of the article for those of you who want to double check the Trig and Calculus formulas). Basically, though, there are three types of coatings, each working in a different way. The first two types can be combined with each other to improve their effectiveness; the third type (nanocoating) is so effective it doesn’t need any help.
