Good point. I honestly can't remember the finish on the various copies I had, but I know that the first three were fairly early copies of the lens, so maybe Sigma did indeed make some improvements ...

The copies I tried were sharp enough by f/2. The problem with the first 3 copies I had was AF - they all exhibited the classic front focus / rear focus issue according to the subject distance ...

Personally I'd give the 50/1.4 a miss and either go for the 50 STM or one of the 3rd party options (FWIW I've got the Tamron 45 f/1.8, but there are also two Sigma 50/1.4 options to consider). I ...

I had the original 35 f2 for a couple of years before I upgraded to the IS USM model. (1) Wide open my copy of the newer lens is a tiny bit sharper in the center than its predecessor, but significantly ...

I wouldn't be confident about drawing any conclusions from those images. Have you tried R. Cicala's make-it-yourself detection chart for decentering issues? ...

I'm a big fan of Tamron's 45 SP too. Really like the second shot with the globes.

I had the Sigma 50 EX for just short of 2 years, prior to getting the Tammie 45 which has been my current 50-ish prime for the last 3 years. There's not much difference in field of view between the ...

Thanks for posting your experiences with this lens and please keep it up! I'm not in the market for an 85 just now but it's cool to see more 3rd party options appearing, especially at the budget end.

I've never upgraded from CS5, but for something like this I use a somewhat different technique that goes like this: 1) Open the image and create 2 duplicate layers - I'll refer to the top layer as ...

FWIW I recently spent a lot of time agonizing last year before I finally switched from my original Canon 24-105 to a (used) EF 24-70 f/2.8 II. I feel this was a good move for me. I do fairly ...

The f4 non-IS is a great lens for sure, but another option to consider might be the EF 70-300mm f/4-5.6 IS II USM. I had both the 70-200 f/4 L and the original 70-300mm IS USM for a time and the ...

If you're happy with 24mm at the wide end then I think the 24-105 is actually a pretty good choice. It's not a standout by any means, but it covers a lot of ground for a single lens, copes with ...

Excellent shots. I'm hoping all the excitement over new the RF lenses will start driving down used prices for some of the classics in Canon's line-up. I'd be more than happy to add a few ...

I've not heard of any similar issues with the Tamron 45, and certainly mine is really quiet, so I'd guess a trip to Tamron service is on the cards.

You're in good company - I really like my 45 too.

It's worth clicking through the cookie nonsense - the article is interesting and I thank GCam for posting it. Regarding the GDPR thing I agree - the cookie notices are a pain. There's a ton of ...

No - I'm talking about the actual quick release clamp that sits on the very top of the tripod head. Take a look at the image at this URL: https://bit.ly/2PsKE4M That shows an RRS quick release ...

Google for "bokeh mirror clipping" - it's a known phenomenon with faster lenses in certain conditions. And next time don't carry your spare lenses in your underpants - that EF lens mount can be sharp.

Just a thought: are you able to change the clamp on your tripod head to an arca compatible one? If you've just got a typical ball head it's likely that you can, which would hopefully put the more ...
