How does the Canon 17-40mm compare to the Samyang??? I have been debating a 17-40 for traveling, but I am worried that after getting used to the IQ of the Samyang, I will be left wanting more out of the 17-40mm.
Are getting it tomorrow, well it sure is about 20% less viewpoint on 17mm... but the possibility to have a zoom till 40 could make it a nice lens when on a walkaround. At least more versatile than my 24-70. Don't know if 14mm should be compared to 17mm though, it is quite of a difference.
By the way, I really enjoy the pictures you have taken with the 14mm!
Thanks!
Do not remember if I read it here in CR forum or not, but someone was talking about a focus confirmation chip added to his 14mm Samyang or some other lens. I could be wrong, but if that it's possible then awesome.
Well, that probably was me too. I attached an Optix V5+ to the Samyang 14mm. I chose an Optix V5+ because EMF chips (the cheapest ones) don't work with a 5D Mark III, didn't bother about Dandelion then, read that Optix work and just ordered one. For my new Takumar 50mm 1.4 M42 lens I also got a M42 adapter with built in Optix chip.
You can get dandelion chips to mount on most any manual lens but I don't just how accurate they are for focus.
Very accurate actually when speaking for my Optix chip. Until today I absolutely do not know where the chip gets its information if the focal point is sharp but it works just fine. When using the lens more regularly you also learn to approximately guess the distance to your object which makes it quite easy to focus, especially at such a low focal length. Well but when behind 3 metres it's infinity anyway, so for landscape you can't really do anything wrong.
I would love to snag one of those Samyang 14mm but just don't have patience for manual focus.
It is really no big deal. Anything beyond 3 metres is infinity so for a shot like that you just pop it there, all you need to do then is manually set the aperture on the lens. Don't be afraid of manual lenses as long as you don't want to try out a Samyang 85mm 1.4 for example... totally hardcore to get that focus right wide open.
About Sigma 12-24. Note that there is a mk1 version and a mk2 version. The latter has improved optics.
Well I actually have heard the contrary, on amazon.de for example it is often read that the II performs worse than version I. Opinions differed so much I decided against that lens and went with the 17-40 of which flaws I am perfectly aware of.
