    Max flash sync speed 1/500. Anything to do with sensor?

    in Mirrorless Digital Cameras

    Posted

    Thanks Joseph, Ellis and Jean-baptiste <br>

    Then I do have another question to add to this. Is this same as the high speed flash (that allows sync upto maximum shutter speed)? <br>

     

    I'm not much worried about technical note about it. I know if you use HP flash you will limit the guide number. The battery will drain faster too. Is that the case with this 1/500 flash sync too? Or it just take the battery life? Or there's no difference from normal flash at all from a user perspective? <br>

    Thanks again guys. Ellis, I notice that the D70 has this too. This is very usefull for bird photographers not to lose shutter speed when using fill flash. I'm considering D70. That's one of the reason I've noticed this...<br>

    Cheers

    Max flash sync speed 1/500. Anything to do with sensor?

    May be a stupid question. Does anybody know if the flash sync speed

    has something to do with CCD/CMOS/LBCAST? I've noticed that all the

    professional film cameras and any digital cameras other than CCD

    sensor has only 1/250s flash speed. Latest Canon 1D II is an example.

    Ne camera has only 1/250 and older version had 1/500. Nikon's D2H

    went down in speed too. Does it has something to do with the speed

    of the sensor? Is there any article explaning this? <br>

    "is it really proven that the 10D has less noise than the D100" <br><br> I don't know Ilkka. I heard D100 has more details. You must be right. I'm not a digital camera expert. Anyway I was happy to see that those pro features in a lower end ditital camera. That means for 1000 dollars you will get almost same spec as a 1000 dollar film body (may be more. I'm comparing to F100 and F5). Sounds like D70 = F5-MLU - CAm1300 - stronger built :)

    "I'm baffled why Nikon keeps playing catch up in this game.". <br><br>

    Nikon is in this mood for a while. That doesn't affect us as long as they produce good cameras.. <br><br>

    Pros<br>

    1) Color matrix metering (may help white balance and so the color problem with D100) <br>

    2) Spot metering and variable center weighted metering <br>

    3) Depth of field preview (For macro and wild life workers)

    4) 1/500 shutter speed with built in flash itself <br>

    5) Compatible with CR2 batteries (in case if the battery is down) <br>

    6) Continuous shooting upto 144 images (JPEG Normal � I don�t know what it�s. I want to know about Raw file)<br>

    7) Faster wake up time (D100 was better that 10D earlier. I�m not sure if this is better than D100)<br>

    8) Less shutter lag. They say it�s unrivalled in this class. They may be comparing to 300D <br>

    8) 2000 shots per charge (limited conditions may be)<br>

    9) On demand Grid on view finder. Very useful<br><br>

     

    Cons<br>

    1) Biggest concern - CCD pictures quality. If it�s same as D100, it�s kind of bad. If the noise is comparable to 10D, then it's great<br>

     

    2) No MLU (Big for me. I know better tripod will absorb more mirror slap vibration. I have too see it with my G1548)<br>

     

    3) Plastic body <br>

    4) ISO 200 (if the quality at 200 is comparable to 100 ISO in other cameras, then it�s not a problem. It�ll be good for wild life)<br><br>

    I guess this is better than 300D in features. Curious to see the image quality.

    If you are talking about the sky, it's mainly because you're using a fast film. Faster films will be more contrasty in general. Now try to come down in speed for higher quality. And try slide and see it projected. There's nothing like that. The cost will be same, you can use the same camera, but the joy of watching image is at it's best when projected :) <br><br>

     

    You've a wonderful start. I should say your images are better than my bird shots :)<br><br><a href="http://www.color-pictures.com" target="w-2">Color-pictures.com</a>

    Which tele-prime or tele-zoom for my F80D?

    in Nikon

    Posted

    Try Nikon's 300/4 AFS. You didn't tell what do you want to do. If you are looking for an alround lens, then I would recomment a zoom. If you are always going to use it in the tele end, then I would go for a prime. Sigma 50-500 is surprisingly sharp zoom. It's hard to believe. I think it's sharper than any Nikon or Canon zooms. I may be wrong..Good luck<br><br><a href="http://www.color-pictures.com" target="w-2">Color-pictures.com</a>

    What tripod you are using? After working with 500mm for a while I'm a big fan for Gitzo and their tripods :). After trying many tripods I settled with G1548 which is truely amazing. If the image was hanld held, it's quite possible that softness is because of lens shake. <br><br><a href="http://www.color-pictures.com" target="w-2">Color-pictures.com</a>

    Matrix metering today vs ....

    in Nikon

    My 2 cents <br>

    I bought F5 for two reasons. 1) Matrix metering and 2) Mirror Lockup. Here're some extreme examples of F5's matrix metering<br>

    <br>

    Here's a mirror lockup at 1/4 sec at 1000mm. You cannot achieve this without Mirror lockup <br>

One thing I learned from a friend of mine is that digital pictures, it's easy to get information out of under exposed images too. So one need not worry about exposure in digital as much we do in slides

    Dwight, <br>

    Sorry this is not an answer, a question to you.. Do you have any good scans? How's the noise? Does it match with current digital SLRs? How sharp it is? How's the shadow details??? Just curious.. I'm trying to stay with film for couple more years. <br><br>

    D1X versus D2H

    I don't think it's worth spending time on these. I made a mistake by start my conversation. :) Sorry. Happy shooting everybody friends. I thought a 17mm lens and 28mm lens will not produce same image with 1.5 croping factor. I may be wrong. Yeah above images are not exact same position, but may be around 2-3 meters away. We were shooting together. People know chicago, knows there's only place you can go to get this image. Anyway we were not testing or anything. I'm not planning to do a comparison. But if we shoot again together I'll try this. <br><br>

    Happy shooting everybody.

    I agree with you 100%. Equipment is just the tool and man behind it decides the image <br><br>

    I'm reluctant to buy digital now because of couple of reasons. Major reason is that digital is still growing technology. It'll go ahead and better things will come out soon. Second reason is that projectors are very expensive. I'm not sure when I'll get a projector that replaces my $150 slide projector and get the same quality. There are some great projectors around for $2000-$3000. We've seen how fast the price is going down for computers. <br><br>

    I'm happy to wait and see what's next. If they come out with a digi camera based of F100, that will be great. I still strongly believe that the mega pizel is going to go up and size too. Now people are saying they can print 20"X30" from 6 mega pixel. How's that possible without interpolation? A 6 mega pixel can go upto 10"X15" if printed at 200 dpi. I'm not happy that some program adds data/pixel to my true image based on some mathematical calculations. I'm a maths/computer major and worked with information retrieval in Java. So I know what it's doing. <br><br>

    I know this everyone's personal preference. I want to take some documentaries rather than digital images that's manipulated and information added based on some 'guessing'. It's just my personal preference.

    I agree there's no magic in 24mm. If all the camera manufacturers decide to stay with small sensor as a unity then eventually people will be used to it. But Canon and Kodak already have full frame and they might do it again for the competetion. The price?? You can see how fast since 2000 when Nikon introduced D1 how fast things has grown. Back then 2mega pixel camera was how much? 10K? Now 6MP is only 3500. File size also is not a problem. Howmany computers are there with memory less than 512MB? Howmany of them slower than 1Gz? If you could open 10MB files back in 200, now you can open 50MB files now at the same speed. The question is how much you need. If you are happy with 6MP you can stay with it. But I'm sure if the technology goes up you may have to upgrade too especially if you want to publish. When D1 came out publishers were happy with it. Now I head everybody is asking for 6MP. How can we say this is going to be the standard. If 6MP file is equal to the resolution of 35mm, nobody will be unhappy if it exeeds the quality of 35mm. This will happen because of the industry...<br><br>

     

    Anyway I've joined the conversation because I don't believe that 50mm is equal to 75mm. Mega pixel and price stuff, I just happened to talk about it. Not much of my interest or area because I don't read digital forums much. One day I'll move to digital too. But not sure when... Happy shooting all....<br>

    Love nature, arts and people :)

    May be you are right. The price may not come down that fast. We will hope. But about the portraits <br><br>

    "why can't there be a, say, 60mm that is good for DSLR portraits?" <br><br> I guess the reason 85mm-100mm was so popular in portraits because they had best 'normal' perspective. If you look through your viewfinder (in a 35mm) and look directly at a person 70-80mm is pretty normal. Even though 50mm is considered as normal, around 75mm you will get the same size as you see a subject with naked eye. When the focal length come down, it's more of a wide angle. But I should agree that this is more of personal taste. If somebody like 35mm perspective rather than 85mm we cannot say that's wrong. But I think majorily like it to be equal to above normal so that the subject will stand out more. I read somewhere there're lots of people use 300mm for fashion photography to get the subject more attraction. <br><br>

    I'm not trying to say that digital or 1.5 crop is bad in some way. Not at all. All I'm trying to say is that a 50mm lens in 35mm is not equal to 75mm in digital. In other words crop is not an advantage in that way. It's an advantage if we agree that a small sensor can produce same quality and size enlargement from a 35mm. I know that majority of us do believe this. Personally I don't know the answer because I never tried to a comparison like this. I know this is true when slides scanned with desktop scanners are compared to 6MP digital. But I think if you print a slide directly in old way still slide can produce bigger images with more shadow details. But I don't want to argue on this.. Just my thought. I still use slide mainly because I like to see images projected in large size.

    "A 57 mm lens on a D100 produces the same image as a 85 mm on 35 mm." <br><br>

    I guess I should post a pictre where I saw the difference. Me and one of my friend shot chicago skyline from same spot. He used 10D and 17-40mm lens at 17mm, in theory 27.2mm and I've used film camera and 28-70mm at 28mm. Both image should look same if the croping factor doesn't affect the image. We found in his picture the buildings towards the end are sloped inwards while 35mm slide showed straight buildings. There's no surprise or bad thing in it. If you compare medium format to 35mm you will see the same problem. So the depth field and prespective are the factors you cannot change with crop. I'll try to get those images and post it here.<br><br>

    I agree that 1Ds crop will be slightly inferior to 10D because of the resolution. That's because 10D is newer camera and newer seosor. It's not because it's smaller sensor. I believe in next version of 1Ds there will be more pixels thus will have more resolution. I agree to the fact that if smaller sensor have the capability of getting same resolution as 35mm film, it's definitely a good thing. But things will change. Number of pixels will go up and most probably sensor size too..

    I'm with Donald in this matter. But none of us or even the camera manufacturers know what's going to be the future. But if aps size is going to be the future, the crop is not a bad thing. But that doesn�t change the optics theory. If you like 85mm angle of view for portraits, you really need 85mm lens to get that. I don�t think you will get same picture (depth of field, angle of view etc) using a 50mm or 60mm lens�

     

    But I do believe there�ll be full frame DSLR�s around for the same price as 10D/D100 now in the market within next couple of years, may 10-20 mega pixels. I won�t be surprised if there�s a declaration in coming PMA. This is an uncertain time. So I would rather weight to buy my DSLR until I see the real future. It�s interesting to see that Nikon is coming out with more �Digital� lenses, but canon doesn�t. If Canon comes out with a replacement for 10D with a full frame DSLR, I�m sure Nikon will do the same or they will lose many more customers (as they do every day) <br><br>

     

    Ellis<br>

    I didn�t try the cropping myself. But isn�t that simple enough to think that way? I believe if you do the crop from 1Ds and compare it with 10D picture they are going to be very close, agreeing that 10D can be slightly better in noise because that�s a newer camera. But you should get same angle of view, perspective and depth of field and even the file size.

    Greg,<br>

    I heard many people saying same thing about crop. <br>

     

    I personally don't think the crop is an advantage in anyway. If I get same quality full frame with more pixels I can allways crop the picture. Since there's no issue of full frame like slides if you have full frame you will have advantage for wide angle lens too. For slides if the picture is not full frame, it's not nice to see. But for digital nobody is going to worry about original picture. People see what you present finally. <br>

    If I have the option to buy a 1.5X or full frame with more pizels, I'll buy full frame. I also heard people saying 500mm lens will become 750m. That's not true I guess.<br><br><a href="http://www.color-pictures.com" target="w-2">Color-pictures.com</a>

    Most likely you won't have any problems with F5. It's a tank. I guess KEH will have some return policy. You can inspect your camera within couple of days and see if everything is working fine. I bought mine used and never had a problem.
