Lenses / Re: Something with 50mm L lens that make it different

For me it's color and skintone rendition.

It's the same feeling I get with my 24 1.4 ii and 24 70 ii.

Looks flimsy to me.  I have some rogue flash benders for my flashes (similar idea) and they are a pain to use. Why you would want this functionality in a hood is beyond me

I've recently become very interested in street photography. I've come to the realization that my 17-40mm f/4L, 40mm f/2.8 STM, and 50mm f/1.4 USM are not suitable for this type of photography on APS-C sensors. The 17-40 is just too large of a lens and the 40mm and 50mm are too cropped in. I've decided that I want a fast wide-angle prime. Sure, 24mm and 28mm aren't wide angle per se on APS-C sensors, but with full frame in my future, one of them seems like a good investment.

Now, I've decided to get one of these Canon primes with IS because I have a physical deformity that hinders stabilization on my part. But I'm stuck deciding between the two focal lengths. I've run some tests at 24mm and 28mm with my 17-40, but I can't make up my mind. With street photography becoming something I want to experiment with more, which lens would you all recommend? Do any of you have experience with these new IS primes?

Thanks for your help!

Have you thought about the sigma 30 1.4? I had the original version on 7d for years with greet results


 My first attempt.i went ambitious

 This was a 27 shot stack of a wasp using a demo I downloaded of helicon focus.

The wasp wasn't dead so as I was taking this my heart was pounding and I was terrified as his feelers kept twitching. There is a bit of movement in the stitch but I'm pleased with my first effort.

As daft as it sounds, I'm always amazed these creatures have faces.

Canon60d, 100mm macro, full set of kenko extension tubes, raynox 250 10x dioptre.
canon580exii with lastolite softbox

I bought the olympus tg850 for my honeymoon. Fantastic waterproof. Good iq. Super macro is great. 21mm super wide angle. Video really good. Compact.

Plus flippy screen for under water selfies and awkward angle shots.

I have a 5d3, 60d and about 10 lenses including tamron 150-600 & canon 70200 2.8 ii

Does anyone use the think tank logistics manager 30 for storing DSLR gear at home?

I'm thinking this could be a 1 bag fits all solution to store all my lenses and gear but I'm struggling to find many example pictures on the net of what this could fit in.

Anyone got one?

Lenses / AFMA Oddity
« on: June 29, 2014, 06:46:29 PM »
I have a question about afma.

I have 2 bodies (60d and 5d3). They are both calibrated to be the same and All my lenses need no afma adjustments   

However I just bought a tamron 150 600. On my 5d3 it appears to near +6 on the tele end and -5 on the wide end. However my 60d seems to be fine with it.

Is this possible? Or must my tests be wrong.

You do realise, that f/4 on FF is still thinner DoF than f/2.8 on APS-C, right?

This is incorrect. A lens mounted on full frame or crop will deliver the same dof at the same aperture. Ie if you mount a 50 1.4 on a 70d or a 6d both will have the same dof. It's the same glass. But the angle of view will obviously be a lot wider on 6d

three legged thing (3LT) brian. A fantastic travel carbon fiber tripod. I used with my 5d3 + 70-200 no issues. Super light, super strong.

Plus one of the legs unscrews and it becomes an extremely light monopod

It's not without its stellar performance reputation and extremely consistent build quality that the EF 70-200 f/2.8isII has found it's way into just about every Canon professional's bag on the planet. From this point it's frequently stated as being a "most-used" lens. So what's happening for you?

There is a chance that it is a very rare poor copy, it's in serious need of AFMA adjustment, there is comprehensive user-error or the unlikelihood of you being a malicious troll. I doubt this is the case!

Read up on AFMA (auto focus micro adjustment in case you were unsure) and do the adjustments as a start point.

This tends not to be a lens that disappoints. If you bought second hand, there are the occasional copies that have been dropped/damaged and badly repaired, then dumped into the hands of a trusting, unsuspecting buyer. As with anything pre-owned, YMMV.


You can afma easily using the af beep method.

Tripod mount
Manual focus a subject with 10x live view. Preferably a subject some noticeable  detail
Set focus to manual.
Set af confirmation to beep.
Adjust afma back and forth and press the shutter button on between each time, noting the point where the beeping stops.  Then average the result.

Eg if it stops beeping at -3 and 3 then your lens is spot on.
If it stops beeping at -6 and -2 then set your afma to -4.

Repeat a few times for greater accuracy.

It is quick. Simple and free. I calibrate all my lenses this way. It works great for me. Better than using software

Don't buy a 7d. It's old tech.

If you can afford it id buy a 70d or 6d.

If your struggling for funds just buy a 1100d and make do whilst you save up for something better

Thanks everyone for the comments. I think ill errr on the side of the tamron. I really want 600mm so think it would be better (and cheaper) to go with that. And just suffer any slow af at the long end or any softness wide open.

Lenses / Need a 600mm. Don't want to pay for one

I want a 600mm focal length for zoos on my 5d3 but I can't afford the big canon glass.

The options I'm considering are:

Tamron 150-600 @ £950


Sigma 120-300 Sport @ £2500 + a 2x TC

I can afford either of these options but not both. My question is, which will be better at 600mm? considering, IQ and AF speed.

I have the canon 70-200 2.8ii so the sigma for its 120-200 range doesn't excite me (neither does the cost or weight). but 300mm f2.8 excites me, so does 400mm f4 but I not sure about 600mm via a 2x TC.

Have anyone come across a direct comparison of these two routes to 600mm?

All opinions greatly welcomed.
thanks in advance.

use AFMA to correct it.

If you can't correct it in camera send it back to the shop and say it has a manufacturing fault. Ask for a refund or another copy. I've never had any problems in the UK returning lenses with calibration problems.
