    For those who didn't get enough from my review on the Olympus M.Zuiko 8-25mm f4 Pro, here's some additional tests that you asked me to do, my famous brick wall tests 😂 I also want to answer a few questions in this video about the comparison against Olympus popular M.Zuiko 7-24mm f2.8 Pro. Watch and find out which one is for you and whether the new 2021 lens is BETTER than the older, faster brother.

    Press release:

    Panasonic Introduces New Full-range F1.7 Telephoto Zoom Digital Interchangeable Lens for Mirrorless Cameras.

    The LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. (H-X2550) is versatile for photography and videography.

    Newark, NJ (July 7, 2021) - Panasonic is proud to introduce a new telephoto zoom digital interchangeable lens, the LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. (H-X2550), which boasts a large F1.7 aperture throughout the entire 50-100mm (35mm camera equivalent) zoom range with exceptionally high optical performance clearing the stringent LEICA standards. The LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. excels at both photo shooting and video recording, satisfying professional photographers and videographers alike.

    The new LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. (H-X2550) is been designed to be paired with with the LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. (H-X1025), a currently available lens which has been highly acclaimed by creators. They both feature the full-range F1.7 high-speed aperture that provides beautiful bokeh and high descriptiveness. The two lenses cover a focusing distance from wide angle to telephoto, functioning as eight fixed focal length lenses (20mm / 24mm / 28mm / 35mm / 50mm / 75mm / 85mm / 100mm, 35mm camera equivalent) providing the same or an even higher level of descriptiveness than a fixed focal length lens can offer. They have common aperture, high descriptive performance, shape and operability, enabling creators to produce their own unique image product using these two lenses with minimal workflow.

    Comprising 16 elements in 11 groups, the lens system features an aspherical lens and three Extra-low Dispersion (ED) lenses that effectively suppress the axial chromatic aberration and chromatic aberration of magnification. Spherical aberration and distortion are also corrected by the aspherical lenses for stunningly high resolution. The use of aspherical lenses and the optimum design of the lens system results in a compact size and light weight while still achieving outstanding optical performance.

    Compatibility with a maximum 240-fps high-speed sensor drive realizes high-speed, high-precision auto focusing. In addition to the silent operation achieved by the inner focus drive system, the stepless aperture ring and micro-step drive system in the aperture control section help the camera to smoothly catch up to brightness changes when zooming or panning. The optical design achieves exceptional barycentric stability to minimize image shifts during zooming. A focus ring is equipped for intuitive, precise focusing and linear/ non-linear setting can also be switched with this ring. The LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. also excels in video recording performance with a mechanism that suppresses focus breathing at entire zoom range.

    The LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. boasts minimum focusing distance of 0.28m (at wide end, 0.31m at tele end) and the maximum magnification ratio of 0.42x (35mm camera equivalent) for superior macro photography. The rugged dust/splash-resistant* design for high mobility withstands use under harsh conditions even in 10 degrees below zero. Filter diameter is in 77mm.

    The LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. (H-X2550) will be available at valued channel partners for $1,799.99 at the end of August.

    *Dust and Splash Resistant does not guarantee that damage will not occur if this lens is subjected to direct contact with dust and water.

    Chris turns a trip to Calgary Zoo into something of a safari, as he reviews the Canon RF 600mm F11 USM as a wildlife lens. Its long focal length and relatively modest price make it an attractive option for birding and nature photography but, as Chris discovers, it's not without limitations.

    $600-$2,000: 10 Wildlife Photography Lenses Reviewed! - Video

    in Wildlife & Nature Photography

    Posted

    Quote

    Professional wildlife photographers Tony & Chelsea Northrup review EVERY wildlife lens under $2,000 for Canon, Sony, and Nikon cameras. Then, they ranked them from worst to best. The rankings are:

    10. Sigma 150-600 Sport ($1,850)
    Pros: Durable AF
    Cons: Big AND expensive, slow AF, less sharp than it’s cheaper Contemporary cousin

    9. Tamron 150-600 G1 ($600)
    The least expensive lens is also the worst ranked… but if this is all that fits your budget, it’s still a good place to start, and when you’re ready to upgrade you’ll be able to trade it in at KEH.

    Pros: Versatile, Inexpensive, Capable of producing great wildlife images… if you can get VERY CLOSE
    Cons: SLOW AF. SO VERY SLOW. Really soft at 600mm. Our tests have shown it's outperformed by the Canon 400 f5.6 or Nikon 200-500
    TIPS:
    Use the focus limiter
    Shut the aperture down to f/8 if you can

    8. Canon 600 f/11 ($700)
    Pros: Lightweight, Decent close-focusing, Sharp when you can fill the frame, Great stabilization, Decent AF speed (8 of 10)
    Cons: 
    Only works with RF cameras, and we found AF to be frustrating with the R and RP. Thus, we can only recommend using it on the R5 and R6.
    Not nearly as sharp as the 800mm f/11, considering cropping
    Only work with their mirrorless R cameras, and the only R cameras we can recommend for wildlife are the expensive R6 ($2,500) and R5 ($3,900). 
    f/11 gives you less background blur/subject separation
    Lets in less light leading to noise in low light or high shutter speed situations

    7. Canon 400mm f5.6 ($850-$100 used)
    Pros: Light, Well-built, 400mm makes finding subjects easier, adds versatility
    Reason it’s in the test: it’s sharper than these other popular wildlife lenses, even cropped to 600 or 800mm
    Cons: Not stabilized, so you always have to keep your shutter speed at 1/500 or shorter (unless you’re on an R5 or R6). Slow AF. Doesn’t focus very close. Discontinued… but KEH!

    Above this point, it gets REALLY close. There are NO losers

    6. Tamron 150-600 G2 ($1000-$1200)
    Pros:
    DRASTICALLY improved sharpness over the G1
    Handling?
    Light weight
    BEST magnification up close (some breathing)
    Cons:
    Slow AF compared to native lenses
    AF lagged a bit on fast-moving subjects, so birds flying at me at close range were basically always a little out of focus
    Not unsharp, but kinda hazy
    Truly awful chromatic aberration when shooting flying birds
    Above this point, EVERYTHING IS RECOMMENDED. 

    5. Tamron 150-500 ($1400)
    If you’re a Sony photographer who plans to travel or hike with the lens, or you don’t want to drop an extra $500 on the Sony 200-600, this is the lens for you.

    Pros: GREAT AF… but it depends on your body. We only recommend the a1 for wildlife now, primarily because of EVF lag in other bodies. LIGHT. Easily handholdable.
    Cons:
    When you crop to 800mm, the equivalent aperture is f/11… compared to f/8.4 of the Tamron G2 and Sony 200-600
    Pretty bad chromatic aberration in subjects with the sky behind them
    Focus not as reliable as the Sony 200-600, especially with flying birds near the camera, the focus lagged behind the bird a bit, so the tail would be in focus instead of the head.
    Recommended for:
    Sony photographers traveling light or who don’t want to spend $2k on the 200-600

    4. Sigma 150-600 Contemporary ($900)
    Pros: Great price, Great sharpness at 600mm, Good magnification / close focusing. Real-world, VERY sharp shots at close range. Better pictures than the Tamron zooms and it’s big brother. Lock can stop the lens at 150 or 600
    Cons: Slow AF compared to native lenses, Not great for flying birds (missed focus A LOT), Chromatic aberration for birds against a clear blue sky was pretty bad (not the worst)
    Lots of “bad copies” out there (quality control isn’t as consistent as name-brand lenses)

    Recommended for:
    Canon DSLR photographers
    Nikon DSLR photographers on a tight budget

    3. Canon 800mm f/11 ($900 new)
    Pros:
    Sharpest lens in the test
    Good AF
    Amazing stabilization (how slow?)
    Shockingly small and light
    Cons:
    TERRIBLE minimum focusing distance
    Even cropped to 800mm, it’s a full stop slower than the zooms
    Only the R5 and R6 have AF systems and viewfinders we really recommend… but if you have an R5, this lens is a no-brainer. Just carry it with you just in case.

    2. Sony 200-600 ($2,000 new)
    Pros:
    Fast AF
    SHARP
    Internal zooming
    Cons:
    Most expensive
    VERY heavy
    Poor magnification up close
    TERRIBLE focus breathing… 325mm at close range!
    Tips:
    Don’t bother with a TC
    DO attach extension tubes if you want to fill the frame with small animals

    Sony photographers with a budget under $10k

    1. Nikon 200-500 ($1,400 new, $1,200 used)
    Pros:
    Fast AF
    Great close-focusing (puts it ahead of the Sony)
    Cons:
    A couple hundred more than the Tamron and Sigma
