<p class="MsoNormal"]<span style="font-size: 11pt; font-family: Arial;"]Hi
everyone! I need your valuable suggestion.<o

></o

>
<p class="MsoNormal"]<span style="font-size: 11pt; font-family: Arial;"]My camera:
350D [1&half year old] with 18-55 IS and 55-250 IS Lens. The 18 to 250
range is fine for me. I’m not a
professional photographer. I shoot for my MERORY. I’m happy with my camera and
Lenses. But I would like to know if I will buy 70-200 f/4 L [non IS] or 70-300
IS USM will my picture will improve? If it is yes; then how much? [Think out of
100 point how much I’m getting now? After buy any of them how much point will
improve?] I think this point marking will help me to buy any of them[if at all i need?]. For your
information 85% photographs I take in day light & without tripod. Think you
are in this situation – so which one you will pick? <o

></o

<p class="MsoNormal"]<span style="font-size: 11pt; font-family: Arial;"]Hope your
wise suggestion will help me. Thanks all of you.<o

Hi,

I am no pro but just my individual inputs

Many have created pictorial wonders with the kit lenses you have. As you shoot for memory i tend to think as below:

70-200 f/4 L will help you gain a lot in terms of image quality provided you have stable hands as you are planning to buy a non IS version. L series lenses have solid build quality and come with good weather sealing. Also, if you wait for sometime the prices may fall down as newer lenses with latest IS technology implementation are being released. Be ready to get bitten by the L bug; these glasses are pro grade & very tempting.

70-300 IS USM will help you increase your reach and with IS you wont have to bother much about blurry images. In case you dont have very stable hands and want sharp imagesgo for this one you will enjoy it equally. Also saves you some money; with which you could maybe buy a decent tripod. But then no weather sealing and not as high quality pro images as L series.

For comparison of images and more details you can go through Bryan's review of these 2 lenses. Also, compare the weight factor for both these lenses against the lenses you have. I think 70-300 gives you IS advantage and extra reach.

But if you opt for 70-200 f4 L with IS i would go for that one

Good luck,

Daya

Hello

first of all, the 70-200 non IS isn't weathersealed! Be carefull it's only with the IS-versions.

Furthermore the choice of lens depends mostly on your needs. And of course what you think will improve.

Both lenses are probably better with IQ then your 55-250, but... maybe you don't even really notice that difference.

What is it excactly that you don't like about your lens or need to improve? Your picture will not get better with any of both lenses. The image-quality will probably. I must say the 70-200 f4 is a beast of a lens for such bargain, but you might miss the IS a lot. You need a bit of light when shooting at 200mm with 1/200 minimum speed and f4 minimum. At least if you don't want to pump up your iso.

I would recommend that you try and turn off the IS on your 55-250 and see if you like it and you could work with it. If so, definitely buy the 70-200! If not, take a closer look at the 70-300 and see if you think it would suit you more than your 55-250.

Also take a look at the review of the 55-250, there's at least one mouse over with all 3 lenses you mentioned.

Good luck picking!

<p class="MsoNormal"]Hi Sheiky
<p class="MsoNormal"]<o

<p class="MsoNormal"]Thank you for your lovely reflection. I’m using your lines
here “Your picture will not get better with any of both lenses. The
image-quality will probably.” That’s the answer I’m looking for.
<p class="MsoNormal"]I just want to improve the quality of the picture [if possible].

<p class="MsoNormal"]If the quality of picture is not improve why should buy any
of them?
<p class="MsoNormal"]I walk a lot when I traveled. Basically I’m a backpacker. I
carry a small bag which contain a small water bottle, sunglass, binocular, emergency
medicines, rain coat/windcheater, lonely planet book, food etc., which is
nearly 3-4 kilogram. + Canon 350D, 18-55, 55-250, extra 1 battery, battery
charger, blower with Lowepro bag nearly 2 kilogram. So total wait I carry 6/7
kilo. Normally I walk per day 10 to 18 kilometers with my bag.

The three lenses you are talking about, in order of image quality - EF 70-200mm f/4L USM is better than EF 70-300mm f/4-5.6 IS USM is quite a bit better than EF-S 55-250mm f/4-5.6 IS.

Jan's suggestion to turn off IS on your 55-250mm lens is a great one - if you can live without the IS, the EF 70-200mm f/4L will give you the best image quality of the three. You won't miss the 55-70mm region, and in comparing the 70-200 with the 70-300, keep in mind that the optically worst region of the 70-300mm is the 200-300mm range.

<p class="MsoNormal"]Hi
<p class="MsoNormal"]Thank you for your suggestion.
<p class="MsoNormal"]Is it possible to describe the quality of picture by percentage?
<p class="MsoNormal"]Which is taken at normal day light condition, same subject
and same distance?
<p class="MsoNormal"]Like this: Think my 18-55 capture the picture quality 50%
out of 100. If <span>I will buy 17-55 IS USM
will it be 90/100% out of 100 marks?
<p class="MsoNormal"]What about -
<p class="MsoNormal"]55-250 out of 100?
<p class="MsoNormal"]70-200 f/4 L [Non IS] out of 100?
<p class="MsoNormal"]70-300 IS USM out of 100?
<p class="MsoNormal"]<o

<p class="MsoNormal"]Please remember I’m not a photographer! The equation will
help me understand better.

Thanks Maloy,

first of all, I never had the 70-300 nor the 55-250 so I can't really comment on the image quality. I have had the 70-200 f4 non-IS and I must say it delivers great quality! Really good colors, contrast and superb sharpness. In image-quality terms it will beat down the 55-250 and the 70-300 without a doubt, at least if conditions like lighting are great.

I do a lot of hiking myself and I just recently sold my 70-200. For me the lack of IS is a bit of a problem, also I didn't use it enough. Where I live, the Netherlands, you have quite grey and "dark" winters. There's not a lot of sun and light... When I walked early in the morning or later during the day, the lack of IS did make me a bit unhappy. You need at least 1/200 of a second to make sharp out of hand pictures. When there isn't a lot of light and your minimum aperture is only f4 you need to boost your ISO a lot. Which I really disliked on my 50D and I guess it's not much better on your 350D.

That's where the IS comes in. If you could make the same picture 2-3 stops slower and thus having the opportunity to also lessen your ISO 2-3 stops you could maybe get a nicer picture from an 55-250 than from a 70-200 L-lens (brutally said). At least if your camera's high iso capability isn't that great.

That's why I mentioned that you should try out to shoot some photos with your 55-250 with turning IS off and then figure out if you could live with it or not.

So my point: in good circumstances the 70-200 will win hands-down, but in other circumstances, mostly personal, you might not really get the results you hoped to get. Please try your lens out with IS-off and tell us what your findings are.

Jan

Thanks Sheiky

Yes. Tomorrow i will try some with 55-250. I would like to share the result of those photos. How can i upload the photographs?

The 70-200 is a very nice lens, and very well built, I have one and love it. That said,what you get with it is the better sharpness at large apertures, and the excellent construction. As long as you are stopping the lens down to 5.6-8, there will not be much difference in the image quality. If you want to shoot at F4, then its a big improvement. All lenses look very sharp at F8.

Since you are shooting in daylight, it probably won't be a big difference in IQ, if any at all.

One thing you might want to experiment with is depth of field. Buy a cheap 50mm F 1.8 lens and start practicing with large apertures and shallow depth of field. This will isolate your subject from the background and create some very memorable images.

You should see this:http://www.The-Digital-Picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=104&Camera=452&Sample=0&am p;FLI=3&API=3&LensComp=456&CameraComp= 452&SampleComp=0&FLIComp=5&APIComp=3

At f8 you could see a difference in sharpness, not even to speak of color and contrast, chromatic aberrations etc etc. The 70-200 is much more valuable. IfMaloyrajucould live with shooting without IS. The 70-200 will certainly make him very happy! Much more then his 55-250.

Thus I strongly disagree with you on this one.

That's for sure. The 70-200 is very usable at f4, it really kicks ass.

My idea remains: if he could live without IS, he would definitely be very happy with all aspects of the 70-200 f4. One downside of the 70-200 is the white/grey color, which makes you less stealthy, that's the only downside I can think of. And it's a downside which is very personal and very easy to solve so....
