Site Information / Re: Moderators: You are Too Sensitive
« on: February 03, 2013, 03:30:37 AM »
I'd like to comment that I read the purple thread but didn't write anything because the op really seemed disturbed (though of course I cannot tell from just reading some outbursts). But towards the end it got more calmed down and had an interesting topic - how important is camera gear in comparison to other real world issues?

I found some thoughts on this valuable, esp. since I recently spend the money originally reserved for top 5d3+24-70ii gear for other, but more important real world purposes, so I'll end up with a 6d+24-70vc ... but I'm happy with my decision.

Could not agree more, the karma thingy was removed as well due to thin skin of some.

As far as I remember karma was removed because there was some abuse and, imho more importantly, it just didn't work - people confused "agree/disagree" to a particular post with an overall rating of a poster, so being critical esp. towards Canon products drove your karma into the ground which I find unfortunate for matter of fact discussions.

It ended with the racist rant. Most countries have laws about that.... to allow it to remain, particularly after the moderator was made aware, is to invite legal action against CanonRumors.

Well, I didn't read the post, but there's always freedom of speech that has to be weighted against opinions (idiotic as they may be), to remove a racist post is probably more good taste and common political sense then preventing a lawsuit.

You lost me with the lens cap thing... neither 70-300L nor 17-40L have 82mm filters.

Doh, typo - it is "hood", not "cap". Canon was smart enough that with a step-up adapter even 82mm filters fit into these lens hoods, I was surprised myself when I discovered it.

Wow - tough crowd! We have 12+ pages of posts and this is the first direct comparison, if I am not mistaken. And I am been hammered for 10% or so difference in framing, and for wasting bandwidth!

I didn't want to cause undue alarm or attack you, and the surgar-coated version is also available  ... I just tried pointing out that some tiny headroom for even further future improvement exists, but your input is very much appreciated and even at the current state great and very helpful  :-)

Maybe I'm a bit over-critical, but I often observe researchers that for some matter discover exactly what they went out to find and knew before - it was a bit like that with your comparison shots: We know the 135L has better bokeh, so why bother with a real comparison to prove it :-p ?

Actually, for something "well-known" I've never heard that.  Interesting information.  Personally, a 95mm filter size would not have impacted my decision in purchasing such a lens.

I have to say this would matter to me, for two reasons:

* compatibility: 82mm filters fit into all my lens hoods, from the 70-300L to the 17-40L - with a 95mm nd/polarizer I'd have to shoot w/o any lens hood which I don't like because of protection & flare.

* price: there are only so many good 82mm filters (the b+w mrc nd filters are just being released), and they are very expensive. So if I pay €80 for a 77mm filter, €180 for a 82mm one I really don't want to know what 95mm filters with the "early adopters" premium would cost.

But I know people that can afford a €3000+ 24-70/2.8IS will be able to get around these limitations, but I like that the cheaper Tamron & current Canon mk2 "only" have 82mm threads.

Ugh, not exactly inconspicuous or easy to transport :-o

and did notice quite a bit of flare...

Flare control is an issue with uwa lenses since you are bound to have light sources in the frame, the aps-c flavors differ quite significantly, too ... let us know your findings, personally I'm happy my 17-40L is said to be rather flare resistant. Btw: Removing flare is hard to impossible, but if you want to add cool looking flares, there are multiple nice photoshop plugins out there :-o

I was too lazy to use a tripod and frame carefully.

The framing is rather different, moving the 100L towards the doll would have resulted in more background blur. No doubt the 135L is much more bokehlicious(tm), but if you want to do a comparison it'd be done properly, or you can also save the upload time...

Depends on how much you're looking to isolate the subject and how much you're looking to put it in context. Each has its place, in other words.

You constantly write reasonable things, please keep posting on CR :-)

For reverse macro to produce ok results a wider ~24mm lens lens is needed *and* it has to be sharp at the aperture you shoot with - and since the aperture cannot be manually set on the 50mm, that's the very unsharp 1.8 setting.
this is actually not true. you can use any aperture you would like with reverse macro so long as you engage the DOF preview button before you unmount the lens. the aperture will close down to whatever you set it at and then will hold after you unmount the lens. i have used the 50mm at 5.6 to get a bit more DOF as at 1.8 reversed it is ridiculously narrow.

Damn, I didn't figure that out when I tried the reverse macro - stopping down doesn't improve the mediocre max. magnification of the reversed 50mm lens, but it sure would improve the iq.

EOS Bodies - For Stills / Re: 6D vs 5D2 in camera JPEG sharpening method
« on: February 02, 2013, 01:17:31 PM »
Personally i like 5D2 in camera JPEG sharpening method rather than 6D, but luckily i often use RAW file, so i can manage my own sharpening method.

The 5d2 has the sharpest sensor output, esp. at lower iso, of the 5d2/5d3/6d generations, so it can do with less in-camera postprocessing. The 6d is at the other end of the scale, it trades some sharpness for higher iso capability - to compensate, Canon obviously has implemented more aggressive sharpening. I don't think you can do anything about this except bug Canon for a fw update.

I remember this issue being discussed when the first 6d raw and jpeg samples were out. This is more or less the difference between the "pro" 5d2 and the 6d which is tuned for sooc amateur shots, Canon has to protect their 5d3 after all :-o

Btw. the difference between your sample shots is really larger than I'd have expected it, maybe some other problem is at work here in combination with the above sensor difference.

So, if you stand in the same place and take a shot with a 50 f/2 and 200 f/8 and crop the 50 to the same angle of view as the 200, you get, for the most part, an identical image.

Thanks for the explanation! Though I have to comment/ask if the bokeh is not also very dependent on the lens build, i.e. the design of the aperture (blade number and rounded or not) esp. with point highlights in the background?

Pricegap:  :'(

I recently started buying all plastic items, cables, tripod plates, ... from China via eBay, up to €22 there's no tax or vat, up to 150€ only vat (MwSt) ... even considering the fact domestic importers have to pay both and add a profit, the price for plastic items is ridiculously high via Amazon Germany, I'd rather wait 2-3 weeks for a delivery from around the globe.

I bought the grip from Ayex.

There seem to be other brand names for the same item - does your grip have also the blue 60d markings like the Meike one described above?

95€ @ amazon [...] So, it was a good deal. 265€ for the Orirginal Grip is a little bit to much  :o

Then again, shipped from CN it's currently €50 + €10 tax if you're unlucky (I missed the €30 deal, shame on me).

now, i avoid using it for anything other than reverse macro shots.

I also tried that and came to the conclusion that the mag factor with a 50mm lens is too small to be of any value against cropping from a "real" macro lens.

For reverse macro to produce ok results a wider ~24mm lens lens is needed *and* it has to be sharp at the aperture you shoot with - and since the aperture cannot be manually set on the 50mm, that's the very unsharp 1.8 setting.

i do wonder about the 1.4 though. is it really as mushy as the 1.8? i really would be shocked if it were. can the color rendering of the 1.4 be as awkward as the 1.8?

The 50/1.4 is an ok lens, my issue with it is that it hasn't a "real" ring usm but a mediocre micro usm. Just like the 50/1.8 the 50/1.4 is simply outdated, with the 50/1.4 not even being such a great value against Sigma and other competition.

I agree, but I am afraid that if this thread has legs, you will be savaged at some point by a lens snob, or perhaps a lens snob mob.

I'm not in the "big money" league, but I have to admit I almost never use my 50/1.8 anymore except for far in between action nighttime shots because of the noisy af, extremely crappy build quality and very mediocre sharpness. But ymmv on that, I feel esp. with this lens it's very dependent on personal preferences. One thing that is an issue depending on the scene is the very harsh bokeh and non-round bokeh point lights due to the few and edged aperture blades.

But surely it's very good value for the price, though imho more modern Canon lenses have even more value like the 40mm pancake.

thanks, nice to get a reply from somebody who actually studied chemistry

... though I should mention it was quite some time ago and "only" for 2 years, but I did all the basic cooking and theory and have a general idea what might be toxic - which is a lot and becomes more every day, which is part of a reason I didn't end up as a chemist :-o

though ye, I thought that toxins don't always come as a bubbly green liquid : )

Watch out, if you continue to inhale the fumes you might mutate into a hulk-like "super photog", only take stellar shots and can carry a 5d3+70-200L2 all day long without flinching :->

... however some googling suggested that there might be a "phthalates smell")

Ah, well, if you googled it I rest my case :-p ... no, really, I don't want to downplay it and phthalates are banned in Europe for children's toys for a reason. The sad truth is that it's a global scandal, the issue is very complex and cannot be narrowed down to "smell" and you're probably already stuffed with phthalates thorough the food chain (plastic wrappings, esp. in fat foods).

So no smell is better than the a supposed toxic smell, but if you fail to produce children the reason probably won't be the Meike grip :-o ... but please let us know if the smell gets better after a week or so?

Blah blah blah...
Was that a comment on previous posts or a prediction about the value of yours :-p ?

also get the Canon "tripod mount ring D (B)" for tripod use... yes its pricy but all good accessories are...
In this case, I guess you're also buying original, genuine Canon lens caps :-o ... for the rest of us I'd recommend this €18 tripod ring d (I've got it) over the €140 Canon item ... it is a good idea, makes moving the lens on the tripod more precise in comparison to a camera body mount:
