So you want sharper images? Sure, you already know that you should stop down your lens and shoot at a lower ISO; but do you know about how black levels and contrast affect your sharpness? Here are some quick ways that you can improve the sharpness of your images by starting with the results in the camera.
Phase One’s IQ250 is a medium format back meant for the very high end shooter. At 50MP and not being a full frame 645 chip (it is cropped) you get the change over from CCD to CMOS with the smaller overall size as a tradeoff. Additionally, the back packs in Wifi transmission, a touch screen, great build quality, and some of the best RAW files that we’ve tested.
But interestingly enough, the Phase One IQ250′s biggest flaws have nothing to do with any of these or even the product itself.
If you’ve gotten a hold of an interchangeable lens camera of some sort, then you should know that replacing your camera every two or three years isn’t always a viable option. However, that’s something that you should think about in the point and shoot world.
The best thing to do instead is to replace your lenses.
When the Phase One IQ250 was announced, it was expected to outdo every DSLR in terms of image quality out there because of the large CMOS sensor. But when you get to the medium format level, you’re only as good as the body and the lenses. The IQ250 can output great images; but it isn’t without its drawbacks.
Or at least that what we’re finding so far…
When Sony’s full-frame E-mount system was first launched last year, it comprised four dedicated lenses for the A7 and A7R cameras. These were the two primes, the FE 35mm f2.8 and FE 55mm f1.8, and the two zooms, the FE 24-70mm f4 and the FE 28-70mm f3.5-5.6. An FE 70-200mm was also announced along the cameras, and will be available soon. While five lenses is quite a solid setup for a brand-new photographic system, these particular ones offer too little choice for demanding photographers.
The good news is, though, that Sony has been promising more lenses for the system, including a wide-angle zoom, another fast prime lens and a macro lens. Zeiss also announced that they are working on new lenses for the full-frame E-mount system, and theirs will be manual primes just like they made for various DSLR systems in the past. Another fast, manual prime lens has recently been announced by Chinese manufacturer Mitakon and should also soon be available.
Sony Alpha Rumors now heard from an anonymous source that over the course of this year, a total of fourteen lenses for Sony’s full-frame E-mount system will become available. This means that in addition to the five lens previously announced by Sony, there will be nine more coming this year including the ones from Sony and Zeiss that we mentioned above. Together with the Mitakon lens, these will make for a total of 15 lenses.
That’s actually not too bad for a system that by the end of the year will be just over a year old. Also, among these 15 lenses, there should be enough choice for most photographers that are contemplating switching to the A7, A7S or A7R. And let’s not forget, because these cameras are mirrorless E-mount cameras, you can adapt almost any full-frame lens to these cameras, and even use autofocus with some when you have the right adapter. So overall, the lens choice for these cameras is already pretty huge.
Canon better come out with a new image stabilization version of its 24-70mm f2.8 lens already. Canon Watch has spotted the fourth patent in a row that illustrates the Japanese Camera company is planning to develop a new IS version of the ever popular 24-70mm f2.8 lens.
As of late Canon has been putting out patents on IS versions of all its lenses from the other extremely popular 17-40mm f4 lens, long telephoto lenses, and even its standard nifty fifty. The 24-70mm f2.8 however seems like the most likely lens candidate to get the IS treatment as it’s one of Canon’s most sought after lenses.
What’s more, third party lens makers are starting to catch up. Last year Tamron introduced its 24-70mm f2.8 SP VC complete with vibration compensation. We’re also still hanging onto earlier rumors of a Sigma 24-70mm f2 lens, which will probably come with image stabilization. Sigma’s already crammed optical stabilization into the 24-140mm f4 DG OS HSM—which isn’t available on official Canon glass—so it is extremely its new 24-70mm lens will also feature IS.
