was it the £240 price for conversion?

They pointed me to the standard details on their website for prices, so I'd say yes but I didn't specifically ask about the price being the same.

I've had confirmation back from Sigma, they can convert to Sony FE mount but only for lenses that they have released in that mount. So unfortunately no 120-300 at the moment.

Thanks for the update, I’m not convinced the whether it is a viable option. Also thinking from a resale point of view, I think th Canon mount would hold up better

actually the opposite. Sony lenses hold their value better than canon lenses as there are few of them.

Are you saying that i can give sigma my existing 35mm art canon mount lens and they will convert it to proper emount?

yes, for £240

for some of the larger lenses, eg 85mm, its just under £400 though - so might not be worth it on those

Tammy 28-75 in stock, trying to get myself working from home tomorrow so I can get it!

Another experience of focus issues.

 

[jj_glos]

So far, many of those that reported focus issues with the Tamron have all resolved it by setting the camera to focus priority.

Not worth it, sell yours for £400 and buy brand new native FE 35 ART for £650!

 

[jonneymendoza]

How do you go about doing it? Do you have a link to more details on what to do?

yea could do

WEX, I had store credit after a previous return.

True, come reporting the behaviour is only happening in certain modes

Weird though that 1 minute it works then the next it doesn't. That doesn't scream camera setting, FW bug?

You'll lose less money on the Canon, it's true the Sony holds up well but then you probably paid more for the Sony in the first place.

That's the front focus issue not the AF failure requiring them to remove the lens.

I'm hoping the latter is just a small batch issue as I don't like any of the other options in this range at the moment.

 

[Riz_Guru]

Also been very impressed, no mirrorless Ive used until now has beaten my D750 as an allrounder, cant think of any way the D750 is better for my requirements (IQ or AF wise), its (more than) what I hoped Nikon wouldve developed in the D750 mk2 but they have left their development waaaaaay to late. The D750 is 4 years old now.

I have to agree, I too am very impressed when you consider its a £1999 body vs competitors.

Siggy 50 testing in decent light, f1.4 / 1/4000 ISO 100.

Eye AF, 10FPS, subject walking toward me, 24 out of 31 in focus (last 2 were because hit MFD)! MC11 combo cant do that, definitely better than adapted.

A very boring one for anyone wanting to check performance wide open across the frame, click through to full size.

Try it at 8 FPS, in the little I've tested eye af I had better results with that over 10 fps.

Im already hugely impressed but will do

how is the focussing compared to your samyang 35mm f/1.4? and also how is focussing noise compared to it?

Yeah, to be honest the lens locking up so nothing works at all I'd class as a different problem to the front focus issues. Obviously just changing to focus priority isn't going to do much to help with that problem.

AF is better, noise hmmm they're both not dead silent, I wouldn't say either are offensive.

in that case might wait for the ART 35mm then. Will you be swapping to ART 35mm too?

 

[jonneymendoza]

Bodes well for the 105mm sigma art

With the Sigma Art FE lenses?

no I am talking about the tamron 28-75mm.
I am not sure why Jonney felt the need to bring sigma ART lenses in to it!!

[jj_glos]

Amusingly the old Tamron 28-75 works on the mc-11, I forgot how cheap and nasty it was.

That'll be because Jonney's a game changer.

That AF motor lol, optically it was ok. Lots of hit and miss QC.
