Canon Announces T6 Sensor Recall
I want to give credit to Canon for so quickly handling the problem we first reported with some T6 sensors. We announced the problem on April 30th, and within 10 days Canon had determined which cameras were affected (those with Serial Numbers beginning with “01 or “02”) and issued a product alert.…

Sony FE 35 Match-up: Is More, More?
### Time to trash the adapters? Sony has just released a new line of full frame FE lenses that will hopefully eliminate the need to use adapters with lenses from other systems. We just received the Sony FE 35mm F/1.4 ZA Distagon which has the largest aperture in the lineup and we couldn’t wait to…

Announcing C-4 Precision Optics
## Or, What I Did Over Winter Slow Season Those of you who read my blog regularly know I’m not a huge fan of sameness. But new lens releases, lately, have tended to have a lot of sameness. Don’t get me wrong, there have been some excellent lenses released; marked improvements and refinements have…

Just the Lenses: The Great 200mm Shoot Out
For those of you who haven’t read our ‘Just the Lenses’ posts before, these take advantage of our Trioptics Imagemaster optical bench to compare lenses from different camera mounts with no camera involved. Why is that different? Because all other forms of testing (DxO, Imatest, or even photography)…

SLR Magic’s 50mm APO HyperPrime Cine T2.1 MTF Tests
About a year ago, Andrew from SLR Magic came and spent a couple of days in our lab, testing some of the SLR Magic lenses and getting input on improving the optical adjustments on their lenses. At the time Andrew made it clear their company wanted to up their quality and compete with the better…

Addendum to the Nikon 300 f/4E PF ED VR Test
When I posted our Imatest results from the single copy of the Nikon 300 f/4E PF ED VR that we had received, I pointed out that the copy was slightly decentered and therefore the results were questionable. We got a second copy of the lens in today, and this one was perfectly centered. I had planned…

More Canon 400m DO II Comparisons
In an earlier post we were most impressed with how much better the new Canon 400mm f/4 IS DO II resolved compared to the original version. I mentioned that we hadn’t been able to get many copies and didn’t have time to do any other comparisons right then, but that we would do more as soon as we…

The Itsy Bitsy Spider
We spend a lot of time here at Lensrentals getting dust out of lenses. Dust doesn’t affect an image, except in very rare circumstances, but people want their rental lenses to look nice and clean inside and out, and our inspectors check the inside of every lens with spotlights and send any dusty…

A Useful Metabones EF to Black Magic Pocket Camera Article
Way back in the old days, before everything was plug and play, you could buy a computer and accessories from one manufacturer and be certain it would all work together. The cool kids, though, would mix-and-match different pieces and end up with a better system that could do more things than any one…

Sensor Stack Thickness Part III: The Summary
Well, I have to admit this has been a fun series. I’ve learned a whole lot. That’s what makes this so fun — I get some results I don’t understand, get some help figuring out what is going on, and before I know it, I’ve learned something that explains other things I haven’t been able to understand.…

Introducing the Optical Bench
Note: This is a Geek article. If you aren’t into geeky stuff, you won’t be into this. _“We take a step back so that we may leap further.” African proverb_ I wrote a post a couple of weeks ago about our first copies of the Sigma 50mm Art lens, and promised to follow up when we got more samples.…

Yet Another Sigma 50mm Art Post
I suspect I’ll never be on any manufacturer’s “early review copy” list for new lenses. There are already plenty of good early lab reviews on the eagerly awaited Sigma 50mm f/1.4 Art lens at SLRGear, Lenstip, and DPReview, among others. So when we received our first Sigma 50 f/1.4 Art lenses for…
