Lenses / Re: Primelens 24mm for landscape?
« on: May 24, 2014, 05:31:40 AM »
I am looking for am prime lens (<800€) to shoot landscape. Cam is an Eos 6D.
I own an Tokina 4 12-24 and the Canon 28-70 2.8L.
Would the 24mm 2.8 Canon lens a good choice?Other suggestions?

Thanks
Daniela


Hello Daniela,
What do you expect from the prime that Tokina 12-24 can't give you for landscape? What aperture would you be shooting - f/8 until f/11? Is sharpness accross the frame (thus including the borders/extreme borders) a must?
And - compare with previous shots - what is the most focal length you have used for landscape. You will know whether it is 24mm or other FL. Did you compare the 24 f/2.8 with the Tokina at 24? And compared at f/8 until f/11? TDP may have such comparison. I did not check it.

Great shot!


And, absolutely stunning airshow photos! Wonderful.
Love the photos you did of the people with cameras- great to see that.
Though I am a bit worried.....many of them added up some weight....destiny of the photographer?  ;D

interested to see what 7D II has to offer..... ::)


I think it is G.A.S.  :P

What about the 1DX?
A dream no?
And the 16-35 f/4 IS?
choices choices choices...... 8)


Just for the record, I DO NOT have G.A.S....... ;D   I talked myself out of 600mm: http://www.canonrumors.com/forum/index.php?topic=19923.120

1D X would be a dream camera for many us(including myself). If I can talk myself into selling A7r + FE 55mm, then 1D X is within reach..... ::)

Regardless how fast 7D II might be, I highly doubt I would add crop sensor to my kit. Anyways, still want to see the specs



Oh yeah, the specs of 7D MKII have my interest as well. I used to own the 7D and did many pictures. But....I so much love the IQ of my 5D MK III (and 6D) regardless that you will find more things to prove on that one.
Very curious how much they will improve the IQ of the 7D MKII. Maybe, just maybe to trade the 6D for the 7D MKII if IQ is acceptable (my standards/wishes)


Ha, that 600....I still wish for a 300 f/2.8 II but for now I talked myself out of it. Instead spent some money on the 50ART, 35f/2 IS and the 16-35 f/4 IS (ordered it)...guess you can't runaway from GAS

Lenses / Re: Sigma 50mm Art 1.4 Focusing problems
« on: May 23, 2014, 04:56:52 AM »
I just got my replacement lens. I have not had time to run it through FoCal yet, but did a quick test on LensAlign. To begin with, there is no need for adjustment on this one, but I need more time to see if the inconsistencies appear on this one also.

Regarding Sigma and FoCal; FoCal gives information to use with the camera, not the lens. You adjust the AFMA on the body. On a 1DX and 5DIII, as I have, you even have to do all the adjustments manually. The only adjustment that influences the lens is done through Sigma´s own USB dock.


Good to hear you got a replacement and good to hear the first sign is a good one.
Thanks for your explanation about focal / camera / lens.


I used the dock for firmware upgrade only

After 4 copies of Sigma I'm a bit disappointed.
It's a gorgeous piece of glass but needs adjustments.
All copies are front focusing from the beginning and needs +13 or +17 depends on bodies.
So I decided to return and wait a bit longer.
Really don't think new lens should be adjusted at all !!!

Please share your experience with this lens.


Are those adjustments consistent, or do you need to change the AFMA from time to time, that's the real question to ask yourself. We have two forum members who have had to return their 50A lenses to Sigma because they couldn't focus reliably. Sure, 13-17 is a lot, but consistent (correct) focus beats inconsistent focus every time.

Please have a look at the http://www.canonrumors.com/forum/index.php?topic=20723.0 thread.


Unfortunately it's a very inconsistent results, more like hit and miss, at least on two of the lenses.


Did you use Focal software for AFMA or manually with a product like Spyder LensCal?


With Spyder Lenscal only…. didn't have much time for the Focal


Seems to exclude a theory but I am no techie. I thought that maybe the Sigma circuitboard can not handle the Focal AFMA software adjustments and could be a reason that after the AFMA with Focal the Lens is totally screwed.
Oh well, it is really a pitty for Sigma and this lens that the saga with AF seems to continue. For now, I don't have problems with the 50A on my 6D. I need to do some checking on the 5D MKIII. I can't believe the Sigma has problems with specific the 61-points AF of the 1DX and 5D MKIII. I am sure that Sigma did a good checking on that since they this is an very desirable target group for their 50A.

The thing I wonder about your post and others like it is - how many people "need" 36+ MP?

The thing I wonder about your post and others like it is why do you care? I want a high MP body, I can pay for it, and I'm tired of people telling me I don't (why do people overquote?) "need" it. I want it, got it?
I think you were actually trying to quoting me (the over-quoter, LOL), and what I was really getting at is that I'm actually one of those people who want a high MP body and would make good use of it, but it seems like most of the people who complain about this on the forums are the same ones who never print their work and post 800x600 photos on the web (for fear of image theft, no doubt).  They're also the same people who will someday slap their 50L on their new 40MP camera, shoot hand held at f/1.2 and then complain that their images are all soft.

Okay, maybe I'm being "silly", but so many "people" bitch and moan about "stuff" they don't have when they are "barely" using 20% of what today's "cameras" can do.  I hope I didn't over-quote that last sentence ;)

With everyone jumping up and down over the new 16-35 f4 LIS....I thought I'd post a few of my best shots using the 16-35IIL:


Beautiful series. I especially like the first picture. Well done.

**Service update**

I just now received  an update for my 50 Art at the repair shop.

They have ordered the mother board of the lens to replace. I can guarantee, as an old consumer electronics rep guy, they have NO idea what's wrong, and decided to switch out all the electronics and cross their fingers. It's also cheaper to replace the whole board, than to find a single component that might act up, very tricky to find.

So a brand new lens, and they have no idea whats wrong, so they try something. I'm not all that confident, because I still can't believe yet again I got a faulty brand new lens, no way....

I got - some time ago - a new Tamron 24-70. It caused a battery drain problem in my Camera. I had sent it in and they replaced the circuitboard. It works like Sunshine. Fixed the problem. That, by itself, is good.
Less good in your case is they weren't able to find the problem. However such things happens often with PC's as well. Eventually they need to sort it out since it may become an expensive solution if more people will have this problem. Maybe there is a different - cheaper - solution.
Anyhow, glad they are doing something for you. I am curious if it fixed the problem. Keep us updated. Thanks!

« on: May 20, 2014, 11:03:27 AM »
Well, first of all I apologize because I made a small error... Vignetting is obvious at maximum aperture only of 28mm (not 24mm) and a bit more at 35mm

For those asking about AF accuracy:
The lens show a tendency to back focusing a little, something you spot when focusing from 1-1.5 feet or less at maximum aperture. I made a microadjustment of -8 and everything is perfect!

Do I find the IS useful in a UWA lens?
Absolutely. On one hand you get huge advantage when you shoot still (or near-still) subjects. On the other hand don't forget that this lens target videographers as well. The IS is extremely smooth and you can only notice it (hear) when it's turning on or off, not while working.

In the following images you can see the vignetting - which I consider to be of less importance as it is easily fixed - from f/4 to f/8 at 16/24/28/35mm, and the great resolution achieved at the corners of the image (detail from 100% crop) at 16/24/35mm. It's worth mentioning that I haven't correct vignetting and CA, just some tonal values.

All in all it's a magnificent lens guys. Just placed it on top of my list!

Thank you so much for this information. Very, very useful. I already placed the order last week. Looking forward to get this lens and use it.

Here is one I took with the 5D MKIII @f/1.4
No AFMA adjustment yet. Focus on right eye (from viewer perspective)
Hope to do some outdoor photography this coming weekend

Another portrait photo

I checked my 50Art on my 6D and this time I used SpyderLenscal.
Now I am not a pixelpeeper but it seems no adjustment was needed. So I did not adjust it.
I added also two portraitphotos with centerspot focus on the right eye.
It seems that there is no focus to the left or right nor front or back. But I love to hear your opinion.

I did not check yet my 5D MKIII I am going to use Focal next Friday and start some outdoor shots as well.
