Some duct tape should do the trick!
Useless, unless light leak reaches exposimeter.

Lenses / Re: 70-200mm f/2.8 took a bad fall... Any advice?
« on: August 26, 2012, 03:05:24 AM »
I dropped several lense:
16-35 I had to change focus helicoids
200 2.8, 135 f2  and 100 f2 had to change USM
Theire cost was about 130 euros exept the 200 that was 200 euros.
I did not have any issues with lenses though.

I thought that all ISOs value where pushed from 100 ISO.

Lenses / Re: 100mm F2.8 macro vs 100mm F.28L IS macro
« on: August 16, 2012, 01:49:31 PM »
get the 100 f2 USM, really sharp, really nice bokeh, fast AF and 1 stop faster then the macro lenses. For portrati it is much better.

PS I think it is even cheaper

Lenses / Re: Sigma 30mm f/1.4 or Canon 35mm f/2?
« on: August 14, 2012, 01:24:03 AM »
I'll give a try to the 28 1.8. It is a good lens with fast and accurate AF, good bokeh and colors. It may not be the sharpest lens WO, but it is sharp enough. If you close a couple of stop it is very good.
I have had it once and sold it for the 16-35 2.8... then i sold the 16-35 to get the 28 again. Now I use it a bit less just because i got the 35 1.4 L.

Do you need 1.4? Get the 50. Can you live with 2.8? Get the cheaper 40.

Lenses / Re: Unboxing of the the Canon EF 24mm f2.8 IS USM
« on: June 29, 2012, 02:48:03 AM »
while the f2.8 shot of the fower does seems a bit soft, I would not make decision based upon a close up shot test. It is not a macro lens, and it is not unusual that a non-macro lens behave sub-standard in closeup. The 17-55 2.8 IS USM is a good example of a very good lens that behave poorly in closeup photography.
Make some more test with more distant subject to see how the lens behave in its native use.

I Think that IQ of 5dII was allready very good, mutch complayn where about AF, and other hardware stuff like viefinder not 100%. Iq has been improved, maybe somone wanted a biger improovment, but since IQ was what has been addresed has been the hardware. Developing a new AF sistem does cost, build quality is mutch better. There are a lot of improvement over the old model. The bigger IQ will arrive with the 5DIII.

EOS Bodies - For Stills / Re: IQ difference of FF vs APS-C?
« on: June 21, 2012, 01:21:35 AM »
I think that at low ISO difference is marginal, increasing ISO the gap widen. Where I think the biggest difference is, it is more on DR than noise. My 5D has less noise than my 60D but difference is sometimes  scarce, but with my 60D I have to be more carefull not to burn highlight, whereas 5D has greater DR.

EOS Bodies / Re: NEW FF Body that is able to take EF-S Lens
« on: June 20, 2012, 01:54:46 AM »
i think it is quite a useless option.

it's not entirely useless
if the reduced file size of the images can give a faster FPS burst and deeper sustained buffer
ie the camera detects the lens and only processes an APS-C sized image from the sensor resulting in smaller data for each image but can still use the full processing power this sort of function would be pretty handy for action shooters I would think

Off course you will have a faster camera then the FF, but i can't see the point buying 3300 euros, 22mp camera to use it as a 12mp aps-c camera, when you can save money with a 18mp very fast 7D. Thinking of nikon, if i wanted to use my aps-c lenses i would rather buy d7000/d300s than any FF used in crop mode.

EOS Bodies / Re: NEW FF Body that is able to take EF-S Lens
« on: June 20, 2012, 01:32:10 AM »
EF-S lenses where created with the back lens element projecting more inside mirror box. This allows light to reach the sensor more vertically,  But it needed on aps-c camera a smaller mirror. Even if electronically an ef-s lens is able to work with a FF body,  it is impossible to mount it because the plastic ring on the back of the lens that would hit the mirror. Someone has removed this plastic on some ef-s lens to mount and use them on FF, but you would end up with loosing a lot of megapixel cropping images.
I think that if you want to use ef-s lens you better have a crop sensor camera. Even if nikon allows compatibility of their FX camera with aps-c lenses, i think it is quite a useless option.

EOS Bodies / Re: Canon EOS 70D & EOS 7D Mark II Speculation [CR1]
« on: June 01, 2012, 02:18:43 PM »

The general rule of thumb is your shutter speed should be at LEAST 1/focal length. So if you shoot a 200mm lens, your shutter should be at LEAST 1/200. If you really want to be safe, you should at least double that speed. That is why IS is so important.

Dont forget the crop, so on a crop a 200 it should be a minimum of 1/320.

Perhaps, but I'm not entirely convinced a crop body would matter. The crop is just that: a crop. if you take a photo in photoshop and crop down to the center 60% of the pixels, it doesn't make the photo blurry. So I don't see why cropping in the camera with a smaller sensor would require a faster shutter speed. The crop sensor affects the apparent field of view, not the actual focal length, or the magnification. It's just putting more pixels in a smaller space. Now, if a higher pixel density is what requires a faster shutter speed, that would make sense. Since a smaller movement will be picked up by the smaller pixels. But then that would apply to high MP FF too, not just crop.

So I feel it might not be totally correct to just assume a crop body needs a higher shutter speed. Right? Its not the size that matters, its how you use it!
Small sensor are more dense, this is one of the reason why you need shorter time comparing with FF. Another reason is that since you are vieving/printing images in the same way, the images of crop sensora are mignified more this mignifies blurr as well.

Lenses / Re: Would Canon produce new 28/1.8?
« on: June 01, 2012, 01:44:22 PM »
having just renewed 28 2.8, adding IS, I think that it will take a wile before canon will produce a new fast 28mm.
When it will... than i guess it will be a L lens and it may even be faster... it could be a EF 28 1.4 L USM in the same cost range of 35 1.4 and 24 1.4.

I think that DR  of 5D is quite enough for most people/situation. Having more DR may be sometime usefull, but i would never buy a d800 with its huge 36mp/50mb files.
If i had to chose between 5DIII and d800 i would go for the canon.
I am not going to to buy the 5DIII, it is very expansive. I think it may be worth its price, but i do not want to spend so mutch for a camera. Even if i have been tempted.
I think that d800 is very expensive as well. 2800 $ it is not cheap. If I was to spend so mutch money, i would not care spending 500 $ more for the canon.
I don't want to spend so much, but i could spend 1600 euro for 5DII. I would not mind any cheap nikon FF camera, since i have a lot of canon glasses and DR and AF of 5DII suites my needs. And IQ of the camera is very high. Even if it is 4 years old, everybody it is here to say that 5DIII has not improoved IQ over the older model so it must be a High quality 4 years old tecnology.
But if I needed it right now i could go to a shop and buy one.
And I am quite sure that canon will have  FF entry level camera after the 5DII. So i am waiting to see what will happen, even if it will be next year, I am not in hurry.
