Wow, this is exciting. I have been interested in a fisheye but don't want to buy the Sigma or Canon (as much as I love the 8-15L).

If this comes in around $400ish or so, perfect. 12mm for full fisheye coverage? Insane... 15mm is hella-wide as is with fisheye.

^ I agree... The 300 II has some incredible bokeh!

Lenses / Re: Image quality with or without filters
« on: August 20, 2014, 01:10:19 PM »
I have tested this a few times with my Hoya HD filters that I use on all my lenses.

I put the camera on a tripod, live-view focused on something with a lot of detail... A brand new crisp $1 bill for example, or distant foliage (leaves, thin branches) or something of the sort.

I would take a picture with the filter off and gently screw on the filter, not adjusted focus or anything. Re-take the shot.

I did this with various subjects and compared at 100% and up in Lightroom... I never saw any detail loss to be honest. It always looked the exact same.

The only thing I did notice, is that the exposure drops an extremely small amount... You can see the histogram shift ever so slightly between filter vs. not... Hardly any issue... But this makes sense, as the filters generally allow something like 99.6% or 99.8% light transmission or something.

So that is my experience... I have tested personally and never saw any difference. If I did, I wouldn't be using them. I never had an issue with flare, either.

Lenses / Re: 24-70 II slight clicking sound when zooming
« on: August 20, 2014, 01:05:40 PM »
I did check and confirm that the lens I have is the right one... Serial numbers match up.

Also, it appears the clicking is already "fading". Its quieting down after just a little use and I think it will likely just go away soon.

Either way, I am not worried about it. Lens works perfectly and the noise is really no harm.

I can verify the serial number when I get home, but nothing appeared abnormal and had the UV filter on that I shipped it with. 

I am led to believe they did open the lens though, as internal dust behind the front element had been removed. I did not note this when I sent it in, but in the past they have done more elaborate "cleanings" then they should have for me. They don't always go by the book... If they did open the lens, they may have tightened a few things which started the noise.

For example, my 5D3 was sent in for just a check/clean and they ended up cleaning out the viewfinder pentaprism (requires disassembly), foam pieces, wiring and adjusted CMOS position as well. And again, nothing was ever noted wrong with it... They just did it free (not under warranty and with CMS).

Far from just external checks/cleanings.

I have a 24-70 II that was bought new right when the lens was released... Never had any clicking noises.

Until I sent it in to Canon for a check and clean...

When it came back, it now has a clicking sound (two or three clicks when zoomed). I am assuming they tightened some stuff which made the sound appear. I am not worried at all about it, but it is funny that it was silent until Canon had it  :o

Loving this lens... By far the best UWA Canon has (I have owned/used the 14L II, 17-40L and 16-35 II)

This lens looks phenomenal... So happy mine arrives tomorrow. I am sure it will easily become my most used lens, no doubt.  I am even debating to sell off my 24-70 II and switch to a 35L and 85L combo instead...  ;D

Lenses / Re: Filter for Tamron 150-600?
« on: June 12, 2014, 12:26:35 PM »
Even though I am a pro-filter user for ease of cleaning and such, I would avoid one on this lens for a few reasons.

1.) Generally, super-telephotos run into issues with filters at times (see 100-400 and even the 400 f/5.6)

2.) Expensive... Expect to pay $100 or more for a good 95mm filter. The lens itself is only $1000, so your paying nearly 10% of the lens for a filter.

3.) Being Tamron and not Canon/Nikon, if you did damage front element and require replacement I am sure it would be about the cost of your 95mm filter. Canon may charge $200-300 for a front element, but I don't see Tamron having such a high markup on a lens.


If you do get a filter, I really like the Hoya HD's if they come in that size... Otherwise, one of the B+W MRC filters.

I would not doubt if the IS unit has been updated... There was quite a lot of issues with it. I had three personally that failed near the beginning. Recent units have had no issue.

Vignetting at 16mm looks quite good... Much better than the 17-40, from what I can tell. This is good, as when I use the 17-40 for commercial work I generally work in low light situations and stop down only to reduce vingetting, not really increase sharpness.

This lens is looking so good. I am glad I got my pre-order in very quickly at two different vendors (around 6:45am EST the morning they went up for preorder on B&H). Can't wait!

Plan to sell my 17-40 which is only a few weeks old after this weekend...

Reviews / Re: 35/2 IS Review by Dustin Abbott
« on: May 06, 2014, 06:05:18 PM »
I sold my 35L due to lack of use and tried the 35 IS as a cheaper alternative. Only lasted about a week before I decided to sell that off as well.

I find the 35L a better lens overall. The f/1.4 IMO is better than the IS at f/2. IQ is better on the 35L in the center, edges probably similar or better on the f/2 IS stopped down.

Weight is nice on the f/2 IS, but the 35L is really not heavy by any means.

Both are great lenses, but if I got a 35mm again it would be the 35L for sure before the f/2 IS.

With that much trouble, one has to wonder whether the problems are with the lenses or somewhere else ... like the camera or the "driver".

Trust me... It is Sigma. When all of my Canon glass works perfectly in terms of AF and all (4) sigma lenses are all over the place, I think I can rule out operator error.

Optically aside from the one decentered one, they were amazing. The AF though is a whole nother story... Also note, two copies of the Sigma was on one 5D3 and the other two on another. So I can rule out the body as well.

The 35L nails focus. When it misses, it may be slight but usable. The Sigma misses by a mile at times. Makes no sense. With my commercial work I can't risk that just for sharpness. AF is very important. It's not like I didn't try though.... 4 copies over a year or more? It's not like I gave up after one...

I just tried my 4th... Yes, 4th copy of the Sigma 35... I have written Sigma off at this point. I tried, but I just could not deal with the AF.

The first two I tried right when the lens came out... MA changed heavily indoors vs. outdoors... 0 MA near to far outdoors, +10 required indoors. Was a PITA.

Fast forward to last week, I tried another. Copy 1 seemed to work fine indoors vs. outdoors but was decentered... OK, just get another... I have had plenty of Canon lenses that I needed to exchange.

Got the replacement, indoors to outdoors is perfectly fine (thankfully). However, the AF is just way too darn unreliable. Some shots are so far OOF you wonder how the camera ever thought it was right. Yet the next photo be perfectly sharp, the next somewhat soft, sharp again, way out of focus the next, etc... Mostly near infinity focus it had these issues.

I just slapped my 35L back on and sent the Sigma back home for the last time... Until Sigma can have even better AF, the Canon options are for me.
