Lenses / Re: Kitlenses - 50D
« on: April 13, 2014, 03:21:26 PM »
Hi thanks for the replies!  :)

As a planespotter I'm using 50D's and 70-300 IS L + 400 L non IS, so enough mm's there.

I want to use my current 18-55 non IS lens on a back-up 400D for some family-pics, and that's it.
This means my new 'smaller' lens needs to serve for photo's of static/expo and some taxyshots of planes. For this 55mm is fine, but a bit more is better. IS is a must :)

Therefore my budget is limited to approx. 200€.  ;)


Lenses / Kitlenses - 50D
« on: April 12, 2014, 04:31:41 PM »

I would like to buy me a 2nd Canon EF-S 18-55mm f/3.5-5.6 IS. But during my search I also saw a few other lenses that made me wonder if they would be a good alternative..
- Canon EF-S 18-135mm f/3.5-5.6 IS (non STM) I have the opportunity to buy a second handed one at 175€..
- Canon EF-S 17-85mm f/4-5.6 IS USM
- Canon EF-S 15-85mm f/3.5-5.6 IS USM
- Canon EF-S 18-200mm f/3.5-5.6 IS

Anyone for some advice, or good occasion tips? Thx!  ;)

Thanks for the useful replies guys, I think a combi of both the 70-300mm L IS + 400mm 5.6 L will be the final decision, so .. now eagerly awaiting some bonus news, in case I don't get a nice one, I will have to go cold turkey..  ;)


SO the 70-200 f2,8 IS L gives better results, even with a 2x convertor? Better than a 400mm L non is or 100-400mm L IS?

Ofcourse for the price of the 70-200mm 2,8 with convertor, one can buy two good lenses; 70-300 IS L + 400 5,6 L..


Well one can fit on my 5OD and the other on my 500D..  :) It's good to have a zoom and a prime ready for the flying action.

However your remark is true, for that price.. that was my initial worry: will the budget give me better IQ results? It is important for me as I love heavy cropping for close-ups..

well, my budget is limited to max $3000, and for that I can have the following:
- Canon 300mm IS L with converter 1,4 III + 70-300mm IS non L
- Canon 400mm non IS L + 70-300mm IS II L
- Sigma 120-300mm 2,8 + convertor 1,4 from Sigma.

Shall I launch a poll to see who chooses what?  ;D


Thanks for the replies so far!  ;D

.. so the Sigma AF 120-300mm f/2.8 EX DG OS HSM could do a better job (with the sigma extender 1.4) as it is a 2.8.. even better than Canon primes (with ext)?


Correct me when wrong, but that review seems from 2009, and probably tells the story about the extender I or II version.. the one I want is the III version and should not eat away quality.. or am I wrong?

According to http://www.the-digital-picture.com

EF400mm f/5.6L > EF300mm F/4L IS + EF1.4X III

EF400mm f/5.6L > ΕF100-400mm f/4.5-5.6L

Center fully open:
ΕF100-400mm f/4.5-5.6L > EF300mm F/4L IS + EF1.4X III

Edges, Corners fully open
ΕF100-400mm f/4.5-5.6L < EF300mm F/4L IS + EF1.4X III

Hi Tron, do you mean the 100-400 gives the same results as the 300 with extender III ?

And a question that still plays : I use a 50D, that auto-adds a crop of 1.6.. with a 1.4 III extender extra, do I loose more than 1 stop? (300mm F4 + extender III + 50D = f5.6 or .. higher? AND does it still has AF?)


Hi all!  :)

As the title says it all, what do you pro's suggest me to do?
I'm currently shooting the 100-400 mm IS on 50D, and am more or less satisfied about the results (aviation spotting), but as it has had its best time I'm looking for an alternative.

Both the 300 mm and 400 mm primes crossed my mind, but I miss -or mm for the 300 mm or IS for the 400 mm- .
So, would it be wise to buy a 400 mm prime f5.6 non-IS, or 300 mm f4 prime IS with extender now.. or just keep the 100-400 mm IS a bit longer until rumors become reality at an affordable price tag (max would be $3000)?

Note: I love playing with the photoshop elements 'cropping tool', so which one gives the best results for some heavy cropping?

Thanks for your help !  ;)
