One thing I quickly discovered is the intrusion of the lens hood when adapting 35mm lenses onto the medium format GFX. Since the 50mm Sigma casts an image circle closer to 40mm, it's going to pick up more of what's on the periphery of the field of view; in this case it's the lens hood.... Continue Reading →
Enough hyperbole. Mirrorless will not make DSLR cameras extinct the same way film remains extant despite digital. The market for DSLRs will contract significantly, likely surrendering the entry-level, systems camera market to mirrorless, but enthusiast and high-end DSLRs will continue on because you will always have its supporters who will vote with their wallets.
If you'd like to contribute your findings, please include lens specifics (brand, focal length, maximum aperture, lens version, firmware version, and if it's weather sealed or stabilized), adapter used, and camera used. Full sensor sample shots without the lens hood (JPEG, 2000x1500 pixel minimum) needs to be of a white or gray background at the widest aperture at both minimum and infinity focus, repeating this at ƒ/8 and at minimum aperture, be it ƒ/22 or ƒ/32.
This is the first in a series of posts on individual lenses adapted to the Fujifilm GFX 50S with the TechArt Pro EF-GFX adapter. Fujifilm GFX 50S, firmware v3.30 (latest) TechArt Pro EF-GFX, firmware v1.01 (latest) Sigma 50mm ƒ/1.4 Art, firmware v2.02 (latest) Summary: Full compatibility: Autofocus, EXIF OK. This lens shows a correctable vignette throughout the aperture range but is heavily affected by focus breathing. As the aperture shrinks, focus toward infinity causes the vignette to become harder and more pronounced. Despite this, it is easily cropped and corrected while maintaining 45mp or more.
As a Youtuber, credibility should be important to you if you're doing anything more than vlogging your daily experiences. Integrity is the only thing that can establish trust and credibility. So, here are my top 5 ways to establish, or protect, your credibility as a Youtuber.
It's been 3 years since I've gotten back into photography and I wanted to reflect on what I've learned in that time. This is just the first of a few items I'll be touching upon. I wish I'd bought the right camera the first time. I want to address the abundance of Youtubers who often, and loudly, try to talk their viewers out of upgrading their equipment. The line often goes, "instead of upgrading your gear, thinking it will make your photos better, invest that money into education," and then they rattle off the names of affiliated Youtubers who sell online education courses on photography. Realize that this recent trend is wholly self-serving and not in your interest. There are of course those who are so affected by marketing that they believe a new camera will improve their photography but either can't see, or won't admit, that their results are from a personal, and not a technological, deficiency. However, those types are far fewer than these Youtubers would have you believe. More importantly, if you value education, I implore you to seek out a reputable photographer that teaches photographic techniques rather than some nobody whose only reputation is a trail of instagram posts. Just because they charge for their videos doesn't mean they're credible; in fact, your local camera store or public library are 2 places where free, or low cost, but highly valuable sources of education is offered on photography.
As I have alluded to in a burst of recent posts, I am planning to generate a small database of lenses for use on the Fujifilm GFX series. Here's my chance for an introduction to give my rationale and to lay the foundation of this endeavor. I'd like to break this down into three "Y's." Let's begin with a personal "why": I'm choosing to use Sigma lenses to obtain focal lengths and apertures not currently offered in the GF lens lineup. Fujifilm's lineup is sparse at best, and apertures wider than ƒ/2 aren't represented. It's not that I'm a bokeh whore; it's that I need more light gathering for astrophotography and Fujifilm's widest lens, a 23mm, has a maximum aperture of ƒ/4 and that's just not going to work without a star tracker due to the sensor's 51MP resolution. I'm hoping to print a few of these so what counts for "sharp" on the web doesn't work at 20" print sizes. Other benefits: 35mm lenses are much cheaper, especially used prices, and these lenses mostly have direct focusing units unlike the "fly by wire" systems used on Fujifilm lenses. The GFX system just isn't mature enough to have grown both a complete lens lineup or a diverse used lens market.
You're familiar with how they all begin: "this video is sponsored by Squarespace." Ok, well, after that, they then feed you the next line, almost all of it verbatim, "I am not sponsored by (insert brand here). They have not paid me to do this review or told me what to say about it. This review is entirely my own and they don't know I'm making this video. I was/was not provided a sample for the purposes of this review. I am not biased in any way so you can trust what I'm about to say about this product." What they don't mention, obviously, is if they had to return that "review unit." But if you pay close attention, you may catch them using the product in later videos, especially if they were especially laudatory in their review. At least they weren't paid, right? Wrong. Payment is simply one form of compensation. That "review unit" usually comes along with an email that says, "you don't need to send this back to us." Simply put, the item itself is payment. Just because you didn't get to choose the item, the form of compensation or were given a special title associating you with their brand doesn't mean you weren't paid. They paid you with product and exclaiming otherwise is a flat out lie by Youtubers who persistently try to claim otherwise. Rarely are these items cameras and lenses; they're usually "soft goods" or accessories, like bags, lens filter kits, etc. that would likely get damaged during a thorough review period or whose cost of manufacture and/or retail price is so low that the cost of return, reconditioning and resale would consume all or more of the potential profit.
There's a certain couple on Youtube that talks a lot about photography and tends to harp on the value of education also pushes their "free" photography education courses online. You may even begin to believe some of their rhetoric or have heard some of their misinformation floating around. Mind you, much of the technical information they love to claim they're proficient in and knowledgeable about is shit. They'll contradict themselves within the span of 5 minutes. One example is their belief that "professional" lenses on a smaller sensor, like APS-C, will perform worse in sharpness because said lens isn't tuned for the sensor size, yet will then claim that some lenses on 35mm are so sharp, you get the ability to crop the image in closer than other lenses. Realize that these two things are a contradiction and a sharper lens will never give a sensor of fixed resolution higher resolution, perceived or otherwise. How do I know this? Simple physics and geometry. Let me explain:
