Any lens that is capable of taking good shots in a variety of conditions will always be a hit and high in demand. All-in-one lenses offer more flexibility than any other kind, eliminating the need to lug around too much gear. The mm lens by Tamron is one of the latest additions to this category. Vendors market it as the go-to option for zooming in tight for close-ups and taking wide-angle photos.
The question is, does it live up to the claims? It offers premium features like a 35mm focal range of mm, Vibration Compensation for combating blur, 39cm minimum focus distance, Piezo Drive motor, and more. It comes in different fits for various camera types, including Nikon, Sony, and Canon. Check the Price of the Nikonmm on Amazon What we like Superzoom telephoto lenses have always been a compromise, offering wide focal range and versatility at the expense of high aperture figures and image quality.
While this holds for the Tamron mmit does a better job by addressing weak spots and improving specifications. Compared to the previous mm, this lens offers a better focal range and a higher zoom ratio of Its ability to frame subjects 2. The Tamron mm comes with many mechanical improvements that can benefit all-round photographers. The focusing ring is better positioned and supports a full-time manual override.
Its autofocus is a step up, while its VC stabilization is quite useful. The moisture-resistant build, sleeker styling, and compact packaging are a huge bonus. Image quality is probably best at longer focal lengths. The lens also delivers crisp and sharp images across the frame, making it a perfect fit for landscape photography.
Unfortunately, the Tamron mm has its fair share of downsides, starting with a downturn in sharpness at the edges at mm. The other issue is that Tamron assumes that the main subject is almost always at longer settings. Vignetting is not an issue, though, and the distortions and chromatic aberrations can be fixed post-processing.Overview Prices Specs.
Sigma 28-300 vs Tamron 28-300
General info Optics Aperture Focus. Scroll down for more details. Weather-sealed splashproof. Which are the most popular comparisons? General info 1. Has a metal mount. A metal mount is generally superior to a plastic mount as it is more durable. The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes. We consider a lower weight better because lighter devices are more comfortable to carry.
A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products. A shorter minimum focal length allows you to get more of the scene in the photo, and offers a wider angle of view than longer focal lengths.
A longer maximum focal length allows you to focus in on a small part of a scene, and offers a narrower angle of view than shorter focal lengths. Includes lens hood. These are used to block strong light sources, such as the sun, from the lens to prevent glare and lens flare. Optics 1. Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.
The zoom range is the ratio between the longest and shortest focal lengths. A higher zoom range means that the lens is more versatile. A true macro lens has a magnification of This means that the image produced is a life-size representation of the subject being photographed. Aperture 1. With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed.
It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject. Has rounded aperture blades.
Similar to the number of aperture blades, rounded blades affect the way the light gets through to the sensor. Rounded blades, often only found on more expensive lenses, improve the appearance of the out-of-focus areas.
This allows you to attain better, softer looking bokeh in your photos. More blades is often an indicator of a better quality lens. It also allows you to achieve much nicer looking bokeh when blurring out your background, whereas a lens with less blades will often produce harsher, more polygonal bokeh. Focus 1.I'm considering buying a Sigma mm Contemporary lens, and have also looked at the Tamron SP mm lens.
Tamron vs Sigma
The specifications seem to be similar, the major difference in aperture ranges which is not an issue for me. Does anyone here have some hands-on experience with either or both of these lenses, and an opinion on their overall quality? Thanks for any help, William. William KahnDec 22, I'm assuming that your primary purpose for one of these lenses is to shoot at mm. Based on that, if you're talking about the first generation G1 of the Tamron lens, whihch came out inthen the SIgma wins hands down.
The SIgma is much sharper at mm and is compatible with the SIgma Dock which allows you to fine tune focus with a specific body. Thesalesman had personal experience with both--the tamron didn't come up--and much prefered the sigma for IQ and price and weight over the Nikon.
He even preferred it, the contemp. He had taken the sigma on safari and rec'd it highly. All anecdotal, i know, but I am looking at that mix also and came away thinking the sigma was the one, at least vs the Nikon.
Hell, my mileage may vary when I look at them tomorrow.Mercedes w124 for sale
There are a few youtube videos out there comparing them, including head to head sigma vs tamron. The decision is a hard one though because they are so evenly matched. One thing I like about the Tamron though is the foot on it is a swiss arca mount.
But, everyone says they are all very close with no clear cut winner These are heavy lenses and though you'd likely use on a monopod or tripod, you still have to carry them. The Nikon and the sigma S had noticeably more heft than the sigma C. Last edited: Dec 22, John Di LeoDec 22, Thanks, guys. I'm going to go with the Sigma. Stunning images to follow I have the Sigma mm C, reviews and comparisons between Sigma and the Tamron said the Sigma was sharper and a bit better.
I am very pleased with mine. Any firmware updates for Tamron has to be done by Tamron and if the lens is out of warranty you are going to pay. Just something to consider. Sample shot a few months ago at mm. Last edited: Dec 23, Mark KeeferDec 23, Here is a hummingbird shot handheld with the mm C at mm. Cropped, not the best photo, but pretty sharp and I can see a lot of detail in the hummingbird and they are really small.
Really looking forward to this Merry Christmas! William KahnDec 24, John Di Leo and Mark Keefer like this. Sigma is good, but some Tamrons are good too.
Tamron 28 -300 or Sigma 70-300 APO- Which one?

I've seen that people really rate the Sigma. Comments and advice please Thanks Andy. Minimum focus 0. The sigma came out with the highest score of all the lenses tested. The Sigma has a slightly larger aperture at the long end which is where the aperture needs to be as large as possible. ChrisK 16 I'd say it depends on if you want to carry about 1 lens or two. The same thought went through my head a few days ago, but I decided that for the price difference I would rather have two lenses and bought a Sigma mm f3.
Both lenses have macro capability and I'm actually going to sell the Nikkor mm G series lens that came with the Nikon D70, and keep the Sigma. I havent had a great deal of time to test the other than putting it through a few tests last night - but I can safely say I am very impressed with its performance so far.
Tamron have always been slightly lower placed thana Sigma, and for that reason, I am yet to trust them. I have a Tamron and would not recomend it. As the recent test of so called super zooms in PP said they are a compromise and not a very good one.
At the end It is soft wide open on mine this is 5. I curently have no other so nothing to compare it with at this length. However comparing it with my Tamron at 75 the is not only softer but the colour is harsh no nice soft tones.
I think that even though it is very useful to have this range in one lens it is not possible to produce a decent one at this size and price the Canon L series equivalent is a monster in both size and price. I have decided to replace mine with several lenses even though this will cost more and weigh more I think it is worth it. Dear All Thanks for the advice. I think i'm going to stick with Sigma in one form or another.
Probably go for the 70 -everyone who has one rates it! For closer stuff, I'll just stand further back!!!Can anyone tell me why the Tamron costs so much more?
I held both of them today and the sigma seemed to be a better built lens and heftier. The problem is, which one takes better pictures??? Grade 2. But wait! As has been said many times before "good lenses hang around.
My recommendation: put your money into lenses; don't go cheap. If you are on a budget, start with one. You will learn a lens very well if it is the onliy one you have to shoot. I think it is still not the perfect lens to get the best pictures of the SD9, this is only possible with EX or at least APO Lenses but if your are in a really controlled lightening studio and can keep the lens stopped down it might give you good results.
Maybe someone has this lens and can tell us. I'm not a Sigma SD9 owner, but have a lot of Sigma lenses.The Best 24-70mm f2.8 Lens You Can Buy
I've tested the mm hyperzoom and there's an album online. We're working pretty close together with Sigma Benelux and will test the SD9 within a short notice. I believe that's the lens that has been panned. I find it just peachy when there's a need for a very flexible lens. Not as sharp as others, but just fine. I use it Spring when I can get away with a relatively slow lens.
When Summer hits and the tree's blcok the light I switch to the Tamron 2. For still photographers, we feel the Nikon Z5 represents the best value for the money when it comes to full-frame mirrorless cameras. Which is why it receives our top award. The Sony ZV-1 was designed specifically for vloggers, but this compact camera is an excellent option for still photographers too. We got our hands on the brand new Instax SQ1: an easy-to-use instant camera that shoots square format film. Despite a couple of quirks, we think it's a camera that photographers and non-photographers alike will find fun to use.
Sony's a7C is among the smallest full-frame mirrorless cameras you can buy, and in terms of core capability, not much has been sacrificed for the sake of compactness.Working from a null hypothesis, two basic forms of error are recognized: Type I errors (null hypothesis is falsely rejected giving a "false positive") and Type II errors (null hypothesis fails to be rejected and an actual difference between populations is missed giving a "false negative").
Many of these errors are classified as random (noise) or systematic (bias), but other types of errors (e. The presence of missing data or censoring may result in biased estimates and specific techniques have been developed to address these problems.
Statistics can be said to have begun in ancient civilization, going back at least to the 5th century BC, but it was not until the 18th century that it started to draw more heavily from calculus and probability theory.
While many scientific investigations make use of data, statistics is concerned with the use of data in the context of uncertainty and decision making in the face of uncertainty.Dr pimple popper new season 2020
Mathematical techniques used for this include mathematical analysis, linear algebra, stochastic analysis, differential equations, and measure-theoretic probability theory. Populations can be diverse topics such as "all persons living in a country" or "every atom composing a crystal". Ideally, statisticians compile data about the entire population (an operation called census).Webull screener
This may be organized by governmental statistical institutes. Descriptive statistics can be used to summarize the population data. Numerical descriptors include mean and standard deviation for continuous data types (like income), while frequency and percentage are more useful in terms of describing categorical data (like race).
When a census is not feasible, a chosen subset of the population called a sample is studied. Once a sample that is representative of the population is determined, data is collected for the sample members in an observational or experimental setting. Again, descriptive statistics can be used to summarize the sample data.
However, the drawing of the sample has been subject to an element of randomness, hence the established numerical descriptors from the sample are also due to uncertainty. To still draw meaningful conclusions about the entire population, inferential statistics is needed.No cm after ovulation
It uses patterns in the sample data to draw inferences about the population represented, accounting for randomness. When full census data cannot be collected, statisticians collect sample data by developing specific experiment designs and survey samples. Statistics itself also provides tools for prediction and forecasting through statistical models. To use a sample as a guide to an entire population, it is important that it truly represents the overall population.
Representative sampling assures that inferences and conclusions can safely extend from the sample to the population as a whole. A major problem lies in determining the extent that the sample chosen is actually representative.The accommodation was largely excellent and the recommendations for our days were great.
We had one of the best holidays ever, and given that we were in a very unknown environment, did not speak the language and had no experience of driving on the 'wrong side' of the road in snowy conditions, we were very pleased that everything worked so well. Thanks to you all for the great service. The tour was very comprehensive and well organized.
It exceeded my expectations. I have visited over 50 countries. This trip was the best. My son, daughter and son in law are already talking about visiting Iceland. The map, tour book and suggested itinerary were outstanding.
We were not quite sure what to expect, but everything went according to plan. Before our arrival we received a fairly comprehensive information package in the mail including a large map of Iceland and detailed itinerary. On our arrival at the airport we were picked up by a taxi driver who had our vouchers for the hotels, car rental and ferry.
The next day we were driven to the car rental agency, and with our GPS powered-up, away we went. It turned out to be two weeks of incredible scenery, learning and great food. We recommend this trip and company. Me and my girlfriend drove around the country (12 days because we added some extra nights to the base trip) on a self drive tour booked through Nordic Visitor.
We chose budget accommodation throughout and it was beyond excellent. The tour was flawlessly orchestrated by our NV agent. Wholeheartedly an amazing, unforgettable trip. The agent you are assigned is a local, ie. It was brilliantly simple and well detailed (each voucher had contact numbers and addresses to your destinations). Put the information into the GPS you are provided with, and off you go. Need to call your accommodation or activity for more info or because you're arriving late.
NV provides a pre-paid cell phone to get in touch. We even used ours to just call taxis when we needed. NV flawlessly took care of the core details for us, the rest was our own adventure to do as we pleased. If you want to see Iceland, even on shorter routes, NV knows what they are doing. Highly recommended because I would have wasted hours online trying to figure out each days accommodation, activity, etc on my own (especially in the more remote areas).
Iceland lives in my heart now. Booking through NV allowed me to spend more time enjoying this beautiful country, and its wonderful people, without worrying about all the background booking details. From the word go Larus at Nordic Visitor helped us plan our holiday perfectly, and enjoy it to the maximum. We wanted a 5-6 day trip taking in some superjeep experiences both from Reykjavik and up in the north around Akureyri as we didn't want large coach groups or anything too touristy.
