Lenses / Re: Canon EF 8-15mm f/4L Fisheye - Durability?
« Last post by Random Orbits on Today at 09:16:43 AM »
I have used this lens for quite a while, and I'm very cautious with it. The front element protrudes a lot, and I'm sure it will get scratched if i hit it on something. That's why I always attach the hood between shots, Or keep it in front of me where I can see whats coming towards the lens.

The hood also comes loose quite easily, which is another concern. It is however not as bad as the 15mm prime, which jumped out of its hood while I was hiking and the lens was in my bag, and it landed not entirely strait back on the hood, which resulted in the aluminium hood scratching against the front element for two hours. Luckily enough that was outside of a crop camera frame, so it was still sell-able.

It takes some getting used to, but the routine of detaching an attaching the hood while you move around becomes natural, and really should not be a reason not to buy this awesome lens.

The lens cap and hood are two pieces but I take both off at the same time by twisting off the hood.  I don't bother with leaving the hood on only because it can interfere when you want a circular image, and the interface between the cap and hood is not very secure and I'd rather not fumble around clipping the cap to the hood in the field.

Lenses / Re: Another standard zoom advice topic
« Last post by procentje20 on Today at 09:10:55 AM »
Do you find yourself switching a lot from your 24-70 zoom to your 85 prime for the additional reach? If so, that would be another vote for the 24-105, in addition to the other recommendations already posted.

I'm on my second 24-105, and really appreciate the extra reach beyond 70mm. (I also have 50- and 100mm primes.)

The difference in framing from 70 to 85mm is usually the same as taking two steps forward. Normally 70mm is fine for a portrait, and with the MP count on the 5d3 you can always crop the sides off an image. So that is no issue. The basic choice between the 24-70 and 24-105 is price and quality. A stop more stabilization and the latest in lens tech might out way the price difference.

Lenses / Need some advice - lens calibration
« Last post by DRR on Today at 08:52:03 AM »
I recently bought a used 35L, and I am convinced it's out of calibration.

I've seen a bunch of 100% crops from this lens online and I'm 99% sure my copy is just soft. It doesn't begin to get sharp until about f/2.8.  F/1.4 is unusable. It's actually quite similar to the images in this FM thread:

http://www.fredmiranda.com/forum/topic/922937/0

Ultimate sharpness is not critical to me. If it had been, I likely would have purchased a different lens. I've used different copies of the 35L in the past and they neither behaved like this.

I've done a couple of AFMA and it's not any better. From my understanding AFMA will correct front focus and back focus, but FF/BF is not my issue. Even with manual focus, I cannot achieve anywhere near the level of sharpness I should be able to. I was expecting a little soft at f/1.4, and then approximately as sharp at f/2 as my old 35mm f/2 non-IS. I did a "manual" AFMA and got a setting of -8. I then tried the DotTune method and got a similar result, landing at -10 (-17, +3).  FWIW, my 6 other lenses are all within +/- 2  of zero, so I have a fair amount of confidence that my camera is at or near zero. This 35L appears to be the outlier, my other lenses perform similarly on other bodies as well.

So where do I go from here? It's a used lens, presumably out of warranty. If I send to Canon, what exactly am I asking for, a "calibration?"

On a side note, I do have enough points for CPS Gold, would that be a better way to go about fixing this? Would this be covered under their standard 11-point inspection for lenses, or would this type of repair be separate?

Can probably post some pictures later tonight but looking for advice in the mean time.

Lenses / Canon EF 8-15mm f/4L Fisheye - Durability?
« Last post by Ruined on Today at 08:42:40 AM »
I really like some of the creative opportunities this lens offers if used wisely.

But, I am concerned with the durability and scratch-resistance of the front element when the hood is not attached.  Has anyone used this for an extended period of time?  How does the front element look over time?  How easy to scratch the front element if a branch or other object comes into contact with it?  Thanks :)

I've been keeping an eye on them, but don't own one.  Their Ada module on Kickstarter is incredibly overdue. 

Be sure to read all the updates.  https://www.kickstarter.com/projects/triggertrap/triggertrap-redsnap-modular-camera-trigger/posts

Yup been keeping up with all of it. Thanks for the feedback everyone. I do realize it's been delayed but honestly, I'd rather wait and get a good product than just getting something out, which is what most companies would probably do. I'm planning to use mine at weddings on an unmanned camera to fire it off right as someone is at the spot I prefocus and frame using the laser sensor.
