I realize that an EF lens on a crop sensor camera must be multiplied by 1.6 to arrive at the equivalent focal length on a crop camera, but my question; when using an EF-S lens, has the crop factor already been converted? So that an EF-S 17-55 on a crop would be equivalent to a EF 17-55 (if one existed) on a Full Frame without having to multiply by the crop factor?

It kind of makes sense that on an EF-S lens Canon might have already factored in the crop equivalent when stating the focal length. And then again maybe not. Please advise

Ouch! The focus system of my 70-200 F/4 IS was slipping (both in manual and auto), so I sent it in for repair: "600 euro to fix it". I'm almost doubting to get a new lens instead :-\

Just looking for moral support (guarantee period just ended a month before of course ), and wondering if anybody else had this kind of repair.

Longer description: if I point the camera upward, it won't focus from distant to near, the focus group just slips. If I hold the camera pointing downwards everything works fine. Normal horizontal position will work sometimes.

I think a Canon 70D will not presented at photokina 2012. I thought that a new prosumer camera XXD would be imminent, but I think I was wrong.

Since they are two years that the 60D has entered the market, when it could be released an upgrade to the 60D?

give me suggestions

Sorry for my bad english, i'm Italian :-[

For those whose paid full price on 5D III, how do you feel about the 5D III price drop at Adorama Ebay store?

I'll go first. I'm one of the millions people placed a pre-order right after the announcement - YES the very 1st patch with "light leak" ;D ;D issues....I have mixed feeling for Canon when I saw the price drop.

First, I'm happy for those jumped on this deal for $2749 from an AUTHORIZED DEALER with full 1 year US warranty. I would do the same - TRUST ME.

Second, this is just me - Canon allows or accepts the price drop nearly 25% on a 6 months old body....THAT IS NOT RIGHT. This is a lesson & learn for me.

Am I going to place another pre-order with Canon in the future???? am I going to continuous with Canon products??? Time will tell.

What about you? how do you feel?

Based on the worlds fastest growing thread I thought this question would get lost in the 26 pages......

1/4000sec shutter speed I saw some complain that its not nearly fast enough.

I currently own a 450D and that is my max and I can't even think of the times I've gotten that high. Is it really a major draw back?

I thought I saw 1/180 for max flash shutter speed or something like that... thats only for a flash that does not feature high speed sync correct? My 450D is 1/200 max for a slow flash.

Third and final question.... F2.8 Center point how does that compare to other EOS models? Most zoom L glass is only 2.8 fast anyway so is that so bad? and if you use a faster lens it just cant guarantee the accuracy of the focus? Dont really care how many points as I don't do much sports and always use center point.

Thanks for the feed back, I've been shooting for a few years but still obviously have lots to learn from a technical aspect. And would like a camera that will allow me room to grow. I do currently 60% portrait type shots of kids, family 20% landscape although that use to be 90% and 20% weddings as a second shooter for a buddy.

Adorama just sent me a confirmation email for a pre-order of the EOS 6D. The link to the camera does not yet work. But, the description in the invoice says:
ICA6D Canon EOS-6D Digital SLR Camera Body, 20.2 Megapixels, Full Frame CMOS Sensor $2099.00
Fun!
I got wait listed by sending the request to my last Adorama sales agent.

Howdy,

I'm thinking of getting a T3i (600D) converted to full spectrum. Objective is to use it for IR and visible light (with external filters) Have a few queries, would appreciate if any of you could help me with them.

1. How good will the visible light IQ be with a quality UV/IR cut filter when compared to a stock camera?

2. I've read different wavelengths of light focus at different focal planes resulting in chromatic aberration when shooting full spectrum, any remedy to this? Also would I still get CA when say shooting only IR or Visible with filters?

3. Your recommendations on a quality UV/IR cut filter.

Would love to see some samples, if you have any please do post.
Any additional info you can provide would also be appreciated.

Thanks,

I did a high school football game Friday night at a Division 6 high school game and let's just say the lighting was the worst I've ever shot in. Even late in the 2nd quarter, the auto ISO in CWA was registering ISO values higher than what I was wanting to shoot at, and I was even at f/2.8 and 1/500. So I spot metered off the players brightest part and although that left the remainder of the player underexposed, it didn't matter because 1. ISO was about 6400, and 2. the 1DX allows you to pull a TON of shadow detail after the fact in post. I want to emphasize that this is much much easier if ISO is 6400 vs. say, 25,600. This may be a great alternative way to handle this siutation if you dislike shooting at high ISO, which I do. It was still very challenging, but again, I didn't see any of the other photographers shooting anything in the 2nd half, and I still could.

I've recently become the sports photographer for my school and I am interested in finding a good blog or website that I could upload the photos of games that I photograph. I'm looking for something free to upload to and would also like to be able to have a custom URL to some extent (e.g. customname.website.com). I'd also like to be able to make an album/page for each game I photograph. I originally was planning on using Flickr but the fact it limits you to 200 photos isn't going to work out for me.


Thanks for your help!

So I'm saving up for the II and was wondering how much I could get away selling my 24-70mm L I for since they're discontinued. It shows some wear but still works pretty good.

Greetings CR community! I am inclined to update my arsenal, and I'm looking for advice.
I'm currently in the process of becoming a journalist, and I'm looking to incorporate my photography hobby into my profession. I currently have 5DmIII and 70-300L, and that's I think is sufficient for now
However I'm short on cash and that's why I was thinking of maybe trying my skills as a wedding photographer, but I don't know which lenses will I need. Except the 70-300L I've just mentioned I also have 24-105L and Sigma's 50mm.
Any advice?

I am wondering if anyone (preferably a professional landscape photographer) can shed some light on a few things:

1) How did you get your foot in the door in that industry?

2) How were you able to build up your name and get to a point where you can make some real money?

3) Have you found your Canon gear to be enough or do you use medium-format digital?

Thanks in advance.

I've been waiting for this for a while, checking the rumor sites every day. Do you guys think this will release by Photokina? We haven't heard many rumors that makes me doubtful. A positive of that might be that Canon is taking extra time to add some more features, looking at the competition coming from Sony, Nikon, and Panasonic.

I'd use this for both photos and video, so a better sensor for low light, a higher bit rate, better downsampling, and 1080p 60p is a must. I hope Canon delivers.

I know I'm rambling but whatever.

Sorry >_< I'm pretty sure in the time that it's been announced somebody has asked this question.

But will Canon sell the M as a body only camera? I don't really need the lenses that it comes with and I'd rather just purchase the M with the EF connector so I can put a 24-70 I on it or my 24-105 to use it with.

Thanks!

I just did a shutter count on my 1.5 Year old 7D. Its been through quite a bit in a year and a half.

Its almost half-way through its life.

Since people asked... Here are some outdoors comparisons...
First thing I must say is the new lens is exactly 10% brighter. For this comparison, I adjusted ONLY the brightness and made them both as close as I could.
At first glance, they look almost the same. There are 3 crops. Center, Left and Right.
Not only the old lens gets blurry on the edges, but also the horizon line drops significantly! I drew a red horizon line on all crops to illustrate the effect... The new lens has an almost perfect horizon line all the way thru... Amazing!
Sharpness is just awesome. The buildings on the center are probably 3 miles away and the 2 towers on the right hand side are over 6 miles away... Still there is enough detail in them and this is just a 70mm lens.
Check out the Subway billboard on the right... Unbelievable!
I am not a landscape photographer but I used the lens for the first time to shoot a model. In another forum topic I complained about how many out of focus or soft images I was getting out of my 1D X. I was disappointed and frustrated. I must say that I didn't miss any today. ALL images are super sharp and the focus is spot on! I am happy again! The old 24-70 will be on ebay tomorrow!

Here are the links to the comparisons... Just rollover the image to switch and prepare to be amazed!
If you are an outdoors photographer, the perfect horizon line and the sharp edges should be a life changing experience

One more Thing. Since the lens is brighter, it seems more light goes into th sensor, it is even better for low
Light situations. I would guess it's
Like 2 stops brighter. At the studio, When i used to need ISO 640, today I used ISO 400! Same
Lighting setup! Awesome!

Hope u enjoy!

Cheers

Patrick

Canon 5D Mark II + Canon EF 24-105mm f/4 L IS USM

https://www.youtube.com/watch?v=UN4Z-VBS8sk

Ok... If i were to give this a rating it would be a CR2... plausible rumour, but new source...

I picked up a 70-200 IS II (woohoo) from a canon image store in Bangalore... started chatting the manger about the D600, and asked him what he thought canon would do to counter it... he said, straight up, the 7D mkII and a new FF will be out soon!

nothing new, but hey, thought i would share!

Enjoy (i'm off to have fun with my new lens...)

Just got my new 24-70 F2.8L II today!
I ran some simple focus test for fun.
I took a photo of my studio with available light. Handheld 1/160 F2.8 ISO 800.
Single focus point on the red lamp in the center of the frame.
The out of focus "things" on the image are an Ikea lamp in front of me. I did other test shots for sharpness and bokeh.
The bokeh is just a little smoother on the new lens but almost identical... You can see the lamp on the last attachment.
First thing you notice is how much brighter the new lens is. Look at the tufted white pattern on the right.
Then at 100% you really see the difference. Notice how much sharper everything is.
At first I thought I could add some edge sharpening to try to match, and it does get better but adding sharpening also adds noise and artifacts. So a subtle sharpening is fine but it won't match the quality of the new lens.
Color seems similar although I noticed a lot less Chromatic Aberration on the new lens.
I will do more tests when I can. This is a simple, good start, I think. ;D

This isn't technically a macro shot, but I think it's in the spirit of macro photography. Sometimes, you just get lucky.


CDB? by Rick.Scheibner, on Flickr

Hello,

This is my first post to the forum. My interest is shooting at 24mm (on a 5D Mark III) with no flash. Nighttime cityscapes, museum exhibits, indoor group shots, poorly lit indoor events (e.g., cocktail parties, banquets), and outdoor evening events (e.g. social gatherings in patios, courtyards, backyards, etc.) would be the subjects. Would the prime lens be sharper at 24mm f/2.8 than the zoom at 24mm f/2.8?

I would appreciate ideas and opinions anyone might offer (cost is not a factor in my decision).
