50-200 and DxO - any experience?

I am still searching for additional reach beyond my 16-45. Picked up an F 35-70 but found that just a bit short as well. Not willing to give up the 16 wide-end for the 18-135 yet and don't want a bag full of lenses - this is a travel kit. So, I have been looking a bit more closely at the 50-200. It is the perfect size for me and has just about all of the additional reach I will ever need. 55-300 is a bit bit of overkill both in terms of size and reach - I will not use the 200-300 end. This is going to be a VERY OCCASIONAL lens - when traveling I will use it for architectural details, interesting signage, etc...

I am, however, a bit leery of the quality reputation of the 50-200. I recently began using DxO Optics Pro and am very impressed with what it can do. So......my question is is anyone using the 50-200 and processing with DxO and what do you think of the results? Any help and guidance would be appreciated.

Have you considered 50-135mm?

I don't do anything with DxO but I picked up the 50-200 for the same reasons you cite. I also have a 16-45. I've found it to be fine for the intended task and generally quite impressed by it for it's price.

50-135 is too big for the intended purpose.

I tried two copies of the 50-200mm before deciding to go with the 55-300mm. The 50-200mm is fairly sharp (the 55-300mm is sharper), but suffers with respect to micro-contrast. DxO PP can make images look muddy in case the lens used to take them did not differentiate finer degrees of contrast. For comparison: DxO-ed, pics taken with the 18-55mm kit lens looked better than those taken with the 50-200mm. The 55-300mm is in another league, IMO. (I have the DA L version of the 55-300mm, but my copy is very sharp--but I've seen some not-so-sharp copies...)

PopPhoto.com has done a review of the 50-200 Zoom as the Samsung clone:



On the K-x, wide open:

ISO3200, f/4, 1/100; 50mm


ISO2500, f/4, 1/100; 50mm

On 6Mp K100D, all wide-open at their respective focal lengths -

138mm; f/4.5; 1/125 sec; ISO1600


180mm; f/5.6; 1/50sec; ISO1600


125mm; f/4.5; 1/50sec; ISO1600


160mm; f/5.6; 1/40 sec; ISO1600

I'm starting to accept that it really doesn't matter what reputation a lens has; it just matters how your particular copy performs. The only way the reputation matters if you can try 10 copies and pick the best of the lot, in which case whether one design is theoretically superior would matter.

There are probably some truly clunky designs, and there may be no good copies of those lenses, but they're in the minority.

Having never had more than 200mm (300 with a 1.5x converter) on 35mm, I thought the 50-200 would be all I'd ever want, but now I carry the relatively heavy 100-300 (the "bad" model) around in addition, and find it very useful. I tried a copy of the 55-300, but it seriously underperformed both the 100-300 and 50-200. I'm sure that was just the copy I got, and maybe sometime I'll try some additional copies.
