Upgrade UWA

[naryab]

Hi,

I don't need advice to the over-common, "what should I get"... BUT...

I recently bought a 5D, still have a 30D. I ended up buying a 10-22 for the 30D for UWA since my 17/40 f4 wasn't that wide. Now that I have the 5D, I was thinking about selling the 10-22 and 17-40 and put it towards a 16-35 f2.8 mkII. The only thing I will lose is the true 16 on the 30D from the 10mmx1.6 crop, right? Obviously I can shoot 16mm on the 5D and I assume that would be the same as the 10mm on the 30D (love that lens by the way, so I really want to make sure I don't lose anything on the wide side). I know I will also lose the 5mm range on the top, but I also have the 24-70mm f2.8, so I am not worried about that.

Is there anything I am missing here? I will be shooting indoors part of the time so the 2.8 will help out weigh a small difference, if there is one, which I am having problems finding.

Any advise would be appreciated. THANK YOU!! mike

I can see the possible pluses of swapping the 17-40 for the 16-35, but if you plan on keeping the 30D I'm not sure of the logic of dumping the 10-22.

Hi thanks for responding. One thing I think I left out to justify it, would be it is the Canon 10-22 EF-s lens, it won't fit on the 5D. Therefore my thought was the best the 10mm would give me being limited to the 30D would be 16mm. If the 10mm fit on the 5D, I agree, I wouldn't part with it. Does that make more sense? And I don't think it is necessary to be able to shoot "16mm" on both cameras. Obviously with the cost of the 16-35mkII, the sale of the 10-22 would help some, again assuming I don't lose anything by selling it. thanks again

I have the Sigma 10-20 and many of the same lenses you do. I wanted to keep the low end on the 20D so will retain the 10-20. I don't need my 17-85 because the the 17-40 and 24-105 will cover the range on the 20D. Agree with your logic, but for my needs I'd rather keep the high end and low end covered on both camera bodies. Just my two cents.

Thanks again Mel. Your 2 cents helps! :)

The situations when I need my UWA 10-22 (on 30D) are usually pretty specific and they don't often overlap with a need for telephoto. If that's the case with you also, why not dump the 10-22 and use the 5D when you want need UWA and the 30D when you want a lightweight, compact telephoto situation? Seems like that's the benefit of having both bodies.

[naryab]

I am with you on the use of the UWA for specific situations, so the overlap isn't necessary for me. I just want to make sure that the 16mm on the 5D is equal to the 10mm on the 30D with 1.6 crop. I know... I have heard this 100 times and have seen the difference since I have both cameras, but before I lay out another $1600 I want to make sure. LOL

This is a point that will come up for lots of us when we get a 5D (or 6D .... :) )and keep the 1.6X.

The MK II 16-35 looks like a big improvement over the MK I for edge and corner performance on paper at least. I don't think there are many quantitative tests about yet other than http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=412&Camera=9&FLI=0&API=5&LensComp=100&CameraComp=9&FLIComp=0&APIComp=4; the server was giving an error when I tried this earlier.

The only risk I can see is if you swap a sharp 17-40 for a bad copy of the 16-35 MK II; I presume the loss of 5mm at long end is insignificant.

Yes, the EF-S 10-22 and the EF 16-35 Mk II cover exactly the same range, one for APS-C and the other for FF.

I am planning on getting a 16-35 Mk II too, but only once I have saved enough for it and the 5D II whenever that comes out next year.

I will not get rid off my 10-22, and neither wil I sell the 60 macro, for the simple reason that in case I want to travel light, I still have the same options with the crop body, in my case a 400D, as with the FF cam. The 60 can be used on the 5D when you use an extension tube anyway, be it only for macro. I will also keep the Tokina 10-17 Fisheye Zoom, as that is also usable on a FF body :).

But that is just my take :).

Maybe you need ot exchange your 30D for an XTi/400D with a batterygrip, to have a really small camera for superlight travel, a medium weight with the batterygrip attached, and a heavyweight with the FF.

If you still have the 17-40, for the time being you could use that as your UWA on the 5D.

HTH, kind regards, Wim

I reread all the stuff on the 1.6 crop factor when I got my 5D. Pixel for pixel the 10mm on the 30D is different than the 16mm on the 5D. The 5D's pixels are larger (~8um compared to ~6um on the 20/30D) So although the image that gets recorded on the chip of the 20/30D is 1.6x the same image on the 5D, from a pixel count standpoint (XxY pixels in picture) the 20/30D is really only a 1.25x factor. And this is for pixel peepers, but does make a difference it you blow things up alot.

Thank you all again! After your comments and a tad bit more contemplating, I am going to get the 16-35 mkii and drop the 17-40. As far as the 10-22, I might hold on to for a while, and I have decided I can "technically" afford to keep it, if I decide to sell it will be once I have both in hand and test them out.

You've all been a great help, again, and I thank you for your time.

As mentioned above, 10mm on a 30D should have the same Field of view as a 16mm on FF.
I've thought about this as well and going wide on a 5D is a very expensive proposition compared to a 30D with a 10-22. However, you will have a constant f2.8 which no ultrawide zoom for cropped sensors have.

If you can afford it, I think it's a great option. If you plan on using the 30D with a 10-22 for ultrawide use, then keeping the lens maybe of use, but personally, if I had a 5D with a 16-35, I'd probably never use a 10-22 on a cropped body to do the same job, so I'd probably sell the lens to help fund the 16-35 purchase.

Good luck.

Just to chip in, there was a 20D 10-22 @ 10mm vs 5D 17-40 @ 17mm comparison done and the full frame one, my expectation was the lens was the limiting factor rather than either sensor at these focal lengths so it would make sense to keep the full frame UW rather than the other way around.

I prefer to use 10-22 on 30d and 24-70 [or 24-105] on 5D and thus i am completely covering the range between 16-105 [10-22 is equivalent to 16-35 on 30D so i continue the FL with 24-xxx on 5D].
