I wouldn't use the canon filter, it certainly degrades sharpness.

EOS Bodies - For Stills / Re: Thinking of downgrading my 5d3 system
« on: January 12, 2013, 12:50:19 PM »
Mmm,…this is a great thread that most likely many of us can relate.  I myself have purchased professional level gear over the past year,….makes me sit back and think if this is practical….but we all enjoy our profession/hobby.  Just my 2 cents,…my opinion,….sell everything except the 5D III.  Keep the 5D III, it’s a great camera and will serve you well for many years.  Next, save the cash and get a 50 f 1.4 and use this exclusively for maybe 6-12 months just as a photography exercise.  Re-evaluate in year and see what direction to go….

I like this as well. Instead of the 50 f/1.4 you could also try the new Sigma 35mm 1.4, if you like it a bit wider!

I don't think the old 35L will sell for more than it sells now used (max. 1100 USD).

Lenses / Re: 50mm upgrade or 85mm coverage?
« on: December 12, 2012, 02:58:31 PM »
I have the 24L, 50L, and 135L and have pondered getting an 85 or the 100 Macro. Every time I shoot with the 135L, I say, :I love this lens" and doubt if I would use either of the other. Every time I shoot with the 50L, I am so very satisfied, I also doubt I would take out the 85 instead.

I would love to have the 35L, 85L and 200L to technically fill the voids of my current kit, but I have never had a situation yet where the lenses I have left me wanting something more/different.

That's almost the same situation I am in, got the 24L, a converted FD 55 1.2 and a soon to be EF converted FD 135/2. Well I also own the 100L, which I don't know if I really need it and the 15mm fisheye which is always nice to have and the 200/2.8! Now I want to sell the 200 because I don't use it, not even with my 1.4x II but don't know if I should buy the sigma 85 to complete my set...or just sell the 100 as well :D and keep the 3 firstly mentioned lenses and the fisheye... ??? After all the sigma 85 1.4 is pretty similar to the 55mm 1.2, you can always crop the pictures from the latter...

A 8-135mm lens with aperture 4 at 8mm, 2.8 at 15mm, and 1.4 at 24mm and 35mm, 1.2 at 50mm, still 1.2 at 85mm, and 2 at 100mm and 135mm ;). IS not needed, please not too big and heavy, and a variable lens hood would be nice :D. Don't forget the integrated ND 0.3-3.0 filter, and the integrated circular polarizer. Last but not least the lens should be compatible with TCs! Price: 7654$.

Good job, CR commenters.

This means, no more comments necessary! Thank you all.

I tend to believe something is probably going to happen in March of 2013

But what?  :o
Well, last March, Japan had a magnitude 9.0 earthquake.  What could top that?

I don't know, but I had to laugh, black humor for the win..

EOS Bodies - For Stills / AutoISO for Canon 5D Mark II
« on: October 19, 2012, 03:15:55 PM »
The last 5D Mark IIs are selling and after they are sold out Canon could just release a firmware update for the camera which implements the notorious AutoISO in M mode. How hard can it be? Who wants to write an open letter? My english ain't the best, I'll have to pass.  ::)

Do the light inspection test [...]

There is no science to it all and this information is in regard to the literally hundreds of used and new lenses that pass through my hands on a weekly basis. If you think your lens is affected by any thing at all, try and find a local person who is willing to work on things for a fair price.

Wow, thanks a lot for this detailed write up! May I ask you where you work, just out of curiosity?

After inspecting the lens I noticed (almost?) no haze, but there were these very little spider webs on the last element/glass (next to the mount) of the lens. Not the glass you can reach when dismounting the lens, but the next one.

It's incredibly common on older filters and lenses when stored in older containers utilizing products like old open-cell foam, foam padded filter cases, etc. the foam and plastic material break down over time and will cause glass to draw these materials to its surface as a 'reaction' to the breaking down of the petroleum based materials.

I guess that's exactly what happened to my lens. I bought in on Ebay and the seller sent it to me in a non original Vivitar case, which is padded inside, and only the smell inside the case wasn't very pleasant..

try and find a local person who is willing to work on things for a fair price.

I will try, there is one repair shop for lenses and he does all kind of repair jobs. Maybe you can tell me another person/address who would disassemble the lens for me? I believe I would be capable to do it myself, but if I would succeed to put it back together is another question.

Lenses / Re: "White fog" on pictures..
« on: October 16, 2012, 12:57:22 PM »
haze is usually caused by the internal lubricants running over the optics over time. It's a common problem on older FD lenses and sometime isn't noticed at all. It looks like haze on this lens and may affect certain focusing distances.

Thanks Ramon. Now I'm sad! And you are most probably right, while converting the lens there was some lubricant all over the "back part" of the lens. I can't remember exactly where but I saw it. I will disassemble the new mount again and maybe wipe the visible and reachable lubricant away. Maybe this will help a bit, but I don't think so. The lubricant has gone probably already inside the lens, between the glass..do you have any advice how to get rid of the haze (if it'll get worse), except disassembling the whole lens?

Lenses / Re: "White fog" on pictures..

I haven't used filters with this lens, and it has a built in lens hood, no petal, but a cylindrical one. I thought the same first, that it's flare, but on the picture above there was only diffuse light shining through the covered sky, how can this cause flare at all?

I don't think it's fungus. When I look through the lens I just see a fair amount of dust particles, most are kinda transparent and there are just a couple of more whitely dust specks. I don't see any haze inside the lens or on the outer optics, although I have never seen a hazy lens before...

EDIT: And if it would be haze, it would be appear on more pictures, and not only on a very small percentage, or am I wrong with this assumption?

Hello!

I have a nFD 135mm f/2 lens converted to EF mount with the EdMika kit. I like the pictures I take with this lens, but from time to time the pictures have a weird "white fog" (is it ghosting?) overlaying the subject. I don't know why it happens, neither can I predict when it happens. I would appreciate it if anyone could give me a hint what is causing this white fog. I have shot very little with the lens, but I'm guessing the white fog thing happens only when the subject has a particular distance from the lens..is this possible? Please have a look at the picture. Thanks!

EOS Bodies - For Stills / Re: How to proceed?
« on: October 06, 2012, 11:50:02 AM »
Alright, I think I owe an update to all answerer to my post. I even almost stopped my "obsessive day dreaming"  8).

In the mean time I bought a 5Dc, shot 1500 pictures in 4 weeks, and sold it with a nice profit last week. I was more than heavily excited by the pictures the 5Dc offered me. I F______ loved it! I even didn't miss the AutoISO of my 60D at all..

What's next? I will buy an used 5DII, because I don't want to use my 60D any more, after seeing what the 5Dc is able to produce. The shallower depth of field of my first full frame was enough to let me think no more about what kind of camera I want to shoot with. A FF camera comes very handy, as I own only primes, and none has a higher aperture number than 2.8. I also own two manual focus lenses, and only because of that I give a S___ about the antique AF system of the 5DII.

Maybe somebody is wondering why I didn't keep the 5Dc instead of getting a 5DII? Good question, I think it was because I want to shoot video occasionally as well, and the back screen of the 5Dc was just horrible. Also I couldn't hold myself back to sell the 5Dc with profit. Not to forget the lack of AFMA on the 5Dc (still the auto focus of my 5Dc was surprisingly accurate on all of my lenses..)

And yes, I got me a 135mm f/2 lens I was talking about. But not the "modern" EF one, but the old nFD, and already converted it to EF with the kit of Edmika. This happened this week, so I only had the time to go outside with it once (and only using it on the 60D) and honestly speaking, I am somehow surprised by the fair amount of CA. Accurate focusing with it is a another story. And there comes the second thing I liked most about the 5Dc, the large viewfinder! Every time I look through the viewfinder of my 60D now, I am just terribly disappointed. I am looking forward to use the 5DII (after I found one for a fair price) with my new 135mm f/2 lens! The converted lens has AF confirmation, but after my shooting I found out that it's not really reliable, a lot of shots where the AF point was blinking on the non moving subject turned out to be not sharp (at all). On my other converted lens the AF confirmation is much more reliable, and I am not sure why. I also tried the to use the manual focus lens with the ML focus trap feature, and it worked quite good, but it's not really helpful when  shooting moving subjects (at least not for my shooting situations), and for non moving ones you mostly have enough time to focus.

One thing I am (or was) still wondering about, how much influence the pixel size has to the IQ of a camera? I know the 5Dc has the highest of all canon cameras! But after looking it up on the inter web, I guess everything above 4, or maybe 5µm makes no difference any more... :)

Thanks for reading, every further comment is appreciated!
