    HELP and ADVICE needed: I want a new zoom lens for my 7D

    I want a new zoom lens for my 7D

    Some of you already heard about the recent problems I have been having with my 20 year old analog 35-350mm L (white) Canon lens. It seems though as it´s not able to any longer keep up with the sharpness of my current 18MPixel 7D.

    This is some of the few mentiones of the problem in a previous thread:

    The last week, it seems as if some of the images I have taken (even at daylight) seems to be a "bit out of focus"....

    Here is one image.... take a look at the stern of the ship:



    Apparently, there seems to be some issues with the 7D and this problem:

    After some serious testing of all my lenses, it appears as if the main problem lies with the 35-350mm L-lens.

    I brought it down to Japan Photo in Trondheim today, and they were not surprised that it might be a bit soft on the focusing: it's a 20-year old lens made for analog images, and not a lens optimized for a 18-MegaPixel digital camera.

    The lens is no longer in production, and repairs/ adjustments might be too costly, with a not guaranteed result. They basically gave me three options:

    - buy a new lens

    - send it for adjustment (no guarantee for result)

    - live with it

    i think I go for option 3: live with it (until I win the jackpot in the lottery).

    A lot has definitely happened in 20 years and an 18 mp sensor will show any lens defects and weaknesses stronger than a 10 mp sensor.

    If you want a nice telezoom for it`s price the Sigma 150-500 is well worth a mention, i have one and it has never let me down

    That lens has done an incredible job: I think the lens has outlived at least 7 or 8 cameras, both digital and analog cameras. Famous ships like the SS Norway, Crystal Symphony and places from Antarctica to North Cape has been photographed with the lens. Probably more than 100.000 shots of 20 years!

    But, now, the lens might be a bit outdated and old: ready for replacement some time in the far future. I kind of figured that as well, after bringing it in to Japan Photo yesterday morning.

    I guess the OS refers to Optical Stabilization and EX DG version refers to ???

    I really like the SIGMA 50-500 alternative, but there are some differences in price and lettering of these lenses.

    Does anyone have this lens, and what are the differences?

    Is it worth forking over a few thousand more for the more expensive one of them, or is the more cheaper one still a good and reasonable alternative?

        What´s the reason why you plan to sell it, and is that theone you have been using in some of your extraordinary photographs?

          My main reason is size and weight, it`s large and heavy and not very trekking friendly. The other is that it sees very little use beyond 250-300 mm and i can get a much more portable lens that cover the same range.

          However it`s not an easy decision for me and i know i`ll kick myself when that little extra reach it provides is necessary.

          A few shots, all at 500mm, F\8:

            Thanks so much for these samples Speedbird, thank you so much.

            They are indeed great shots.

            Please do remind me, was/is this the 150-500 lens from Sigma retailing at around 7.000 kroner (japanphoto)?

            Also, if I may ask a really stupid question: the 7D is not a full format camera, so when you use a 500mm lens, you really get less (like 350-400mm) out of it?

              Further to my previous, these are the lenses I'm currently are considering:


              1/ Sigma 50-500mm f4.5-6.3 APO OS HSM (retailing at 14.995 NOK at fotovideo)

              2/ (deleted choice)

              3/ Sigma 150-500 f5-6.3 APO DG OS (retailing at 6.990 NOK at japanphoto)

              4/ Canon 100-400mm f4.5-5.6L IS USM (retailing at 13.295 NOK at fotovideo, and 13.980 at japanphoto)

              Which lens did you recommend Dane, the one in your line-up?

                7D crop factor is 1,6, mulituply the focal lenght with 1,6

                I think it is overkill thinking of a 150-500 mm lens on a 7D. The camera has, because of its smaller format than 35 mm, a crop factor of 1,6. So 200 x 1,6 = 320 mm.
                If you go for a 500 mm, multiply with 1,6 and you have a 800 mm monster. This is more than you can handle without a very heavy tripod, most pros would use 2 tripods for this lenght.

                I have been using my 7D since last December with my 70-200 mm, which gives me a real focal length of 112 - 320 mm. This is almost on the edge of what you can use handheld. In addition I have a fixed 300 mm (300 x 1,6 = 480 mm).

                I will advise you to keep to the moderate 4/70-200 IS L, a high quality lens to a moderate price.
                Regards; Sigve.

                  Oh, I see, so it's the other way.

                  I thought you would get less than the actual focal lenght of the lens, when using a camera which is less than full-format.

                  Then, I do understand much better what you say about choice number 4.

                    Sigve, you are right about the focal length multiplier but i have had no problems shooting at 500\800mm handheld or using my modest tripod.
                    The image stabilizer does a really good job at eliminating vibration, all my shots above were shot handheld at max focal length.

                    As for the 70-200 F\4 IS it will be my replacement lens, it`s size and weather sealing makes it the perfect spotting\trekking telezoom in my opinion. Also it`s one of the sharpest Canon lenses available.

                      It's going to be a very hard job deciding which lens to go with: these are some of the lenses Canon makes and are out for sale at fotovideo.no...

                      1. Canon EF 100-400mm F4.5-5.6L IS USM (13 295,-)

                      2. Canon EF 70-200mm F2.8 L USM (10 595,-)

                      3. Canon EF 70-200mm F4.0 L IS USM (8 895,-)

                      4. Canon EF 70-200mm F4.0 L USM (4 995,-)

                      Not easy at all, they do appear the same, but are priced very differently.

                      Another thing is that I do not want to purchase a new lens, just to find out a month later that it's an old version, isn't working well or that another lens would be a better buy.

                        aint there any photoshops where you can rent a lens?
                        here in holland are shops where you can rent a lens or camera for a day.
                        camere dont seem to bee very much,you can´t learn a camera in 1 day,
                        however for a lens you can take that when you go into the woods with extra lenses and try them out what is the best for you

                          I have never heard of lenses for rent before, here in Norway.

                          In Thailand, I would have asked one of my phtographic friends in the photo clubs there... they would almost always be able to help with some of their own lenses. Here, I don't hang out in photo-groups.

                          But it is still a good tip, so I thank you for that one!

                              Both lens no. 2 and 4 are old versions, without image stabilizer, but optically they are top class.
                              There is a new 2,8/70-200 IS L 2, specially adapted for the full 35 mm/full frame format of the EOS 5D mk II and the 1Ds mk ll, but this is not exactly cheap (over NOK 20.000). So choice 1 and 3 are definitely the best.
